This approach, Antidepressant for treatment-resistant depression, treatment-resjstant followed by switching, is consistent with multiple treatment guidelines and systematic reviews deprexsion 9,13,14 ].

Given that Improve your athletic performance efficacy of augmentation is not clearly superior to switching antidepressants, shared decision making with patients is important.
Patients who partially benefit from the initial antidepressant and experience few adverse effects generally prefer adjunctive pharmacotherapy rather than switching [ 18 ].
Conversely, patients who experience less symptomatic improvement and more side effects with the antidepressant prescribed at first presentation typically prefer switching antidepressants.
For treatment-resistant depression, multiple practice guidelines suggest either augmentation or switching [ 9,11,13, ]. Among patients with treatment-resistant depression who augment antidepressants with a second drug and do not respond, it is not clear how many trials of add-on therapy that clinicians should administer before switching the antidepressant.
We generally provide one to three courses of augmentation before switching the antidepressant. When switching the antidepressant, we typically continue the current adjunctive drug, based upon the principle of making only one change at a time.
Although monotherapy often causes fewer adverse effects than multidrug regimens [ 24 ], this is not always the case.
The overall incidence of distressing side effects for each group was similar. For patients with treatment-resistant depression who initially switch antidepressants and do not respond, it is not clear how many trials of antidepressant monotherapy that clinicians should administer before augmenting the antidepressant with a second treatment.
We generally provide one to three courses of next-step antidepressant monotherapy before using augmentation. An alternative to switching antidepressants or augmenting the antidepressant with a second medication is to switch from pharmacotherapy to psychotherapy eg, cognitive-behavioral therapy [CBT] or to TMS, or retain the initial antidepressant and add psychotherapy or TMS [ 13,26,27 ].
In addition, it is reasonable to augment the initial antidepressant with both pharmacotherapy and psychotherapy. However, psychotherapy is often not available, and many patients decline it [ 18 ].
The efficacy of switching to and augmenting with psychotherapy are each discussed elsewhere in this topic. See 'Psychotherapy' below and 'Psychotherapy' below.
Implementation of augmentation and switching are discussed elsewhere in this topic. See 'Initial approach' below and 'Next step treatment' below.
Efficacy of primary treatment strategies — For treatment-resistant depression, relatively few head-to-head randomized trials have compared augmentation with switching treatments.
Although results across the trials are mixed, the most compelling evidence suggests that add-on therapy may be at least modestly superior to switching antidepressants:. Nearly half of the patients had comorbid posttraumatic stress disorder, and most patients were currently receiving psychotherapy.
The primary findings included the following:. In the augment-bupropion group, remission occurred in 27 percent, which did not differ statistically from the other two groups. Anxiety occurred more often in the augment-bupropion group and the switch group, compared with the augment-aripiprazole group.
One limitation of the study was attrition; during the week acute phase, 25 percent of the patients withdrew from the study. Other limitations included the lack of blinding for patients and treating clinicians, as well as the predominantly male sample; major depression occurs twice as often in females than in males.
Nevertheless, other randomized trials indicate that aripiprazole augmentation may be more efficacious in females than in males [ 30 ]; if true, the present study may have underestimated the benefit of aripiprazole augmentation [ 31 ].
Study treatments were administered for six weeks, and patients and treating clinicians were not blind to treatment. Remission occurred more often with aripiprazole augmentation than switching antidepressants 54 versus 20 percent of patients and functioning also improved more with aripiprazole.
In addition, tolerability appeared to be comparable, such that discontinuation of treatment due to adverse effects for augmentation and switching occurred in 6 and 10 percent of patients. Weight gain during the six weeks with augmentation and switching was 0.
More limited evidence suggests that for treatment-resistant depression, the benefits of augmenting with pharmacotherapy and switching antidepressants are comparable:. Pooled remission rates for the augmentation and the switch strategies appeared to be comparable 37 and 41 percent; difference was not statistically tested.
The probability of remission for the two groups was comparable. In some cases, switching antidepressants may be more efficacious than augmentation. Remission occurred in more patients who switched to imipramine than those who added mirtazapine 71 versus 39 percent.
Initial approach — For mild to moderate unipolar major depression that does not respond to an antidepressant, our initial approach generally relies upon augmentation interventions [ 41 ].
Standard augmentation strategies for managing treatment-resistant depression include pharmacotherapy and psychotherapy [ 8 ].
The choice between the two is generally based upon availability and patient preference because there is no compelling evidence that one is superior to the other for acute outcomes [ 42 ]. Pharmacotherapy is typically used for augmentation because it is more available and often preferred. However, patients acutely ill with unipolar major depression who improve with pharmacotherapy and subsequently discontinue it appear to be at greater risk for relapse, compared with patients who improve with and discontinue psychotherapy eg, CBT.
If augmentation with either pharmacotherapy or psychotherapy is not effective, add-on treatment with the other modality may be beneficial. In a trial of patients with unipolar major depression who were initially randomized to monotherapy for 12 weeks with an antidepressant or CBT, did not remit and subsequently received augmentation with the other modality for another 12 weeks [ 43 ].
Remission with combination treatment occurred in 62 percent. Another standard augmentation intervention for acute resistant depression is TMS.
However, it is not known if maintenance treatment with TMS for unipolar major depression is beneficial. Treatment-resistant depression that is managed with add-on pharmacotherapy or psychotherapy may also benefit from supplementary interventions such as exercise [ 44 ].
A week randomized trial enrolled 42 patients with major depression who did not respond to at least six weeks of antidepressant treatment and compared adjunctive aerobic exercise two sessions per week, each lasting one hour, in a physical therapy setting with a single consultation focused upon advice for physical activity [ 45 ].
Improvement of both depression and cardiovascular fitness was greater with exercise. Pharmacotherapy — For patients with treatment-resistant depression who receive augmentation, drug-drug interactions between antidepressants and add-on medications eg, second-generation antipsychotics, lithiumor triiodothyronine are generally not a problem.
However, combining a monoamine oxidase inhibitor MAOI with another antidepressant, such as a selective serotonin reuptake inhibitor SSRIcan cause the serotonin syndrome or a hypertensive crisis [ 12,46 ]. Specific interactions between an antidepressant and another medication may be determined using the drug interactions program included in UpToDate.
Treatment-resistant patients who are treated with an add-on drug and do not respond within 6 to 12 weeks of reaching the target dose, or do not tolerate the combination, should be treated with a second medication combination. We suggest tapering and discontinuing the failed adjunctive medication over one to two weeks at the same time another adjunctive medication is started and titrated up.
The failed medication is generally tapered by the same amount for each dose decrease. As an example, aripiprazole 15 mg per day is decreased by 5 mg per day every one to three days. At the same time, the antidepressant is continued at the same dose.
However, it is reasonable to switch the antidepressant after the adjunctive drug has been switched. Switching antidepressants is discussed elsewhere in this topic. See 'Next step treatment' below. However, we generally avoid complex medication regimens because there are no data supporting their utility, and patients may feel worse due to the cumulative side effects.
Choosing a drug — For patients with mild to moderate depression who are treatment resistant and receiving add-on pharmacotherapy, several options are available. The most widely studied drugs include [ 8,28,36, ]:.
Some patients may prioritize treatment efficacy, and others may prioritize tolerability and avoiding adverse effects.
These approaches are described in the subsections below. See 'Patients who prioritize efficacy' below and 'Patients who prioritize tolerability' below. However, it is reasonable for clinicians to augment with any of these four pharmacotherapy options, because in the few head-to-head trials that compared different drugs, efficacy was generally comparable [ 1,53 ].
As an example:.
: Antidepressant for treatment-resistant depression| Latest news | Recently, it has been used more widely due to its approval for treatment-resistant depression TRD — that is, severe depression that has not improved via other therapies, including people who are experiencing suicidal thoughts. A prescription version of ketamine called esketamine Spravato , given through a nasal spray, was approved in by the FDA for TRD; however, according to the guidelines, it is only to be used "under the supervision of a health care provider in a certified doctor's office or clinic. The effectiveness of ketamine for TRD was first demonstrated for short-term treatment in research that resulted in clinically and statistically significant decreases in depression scores for ketamine versus placebo In both groups in this study, the patients continued with their regular antidepressants because of concern of not treating TRD in the placebo arm. Nasal ketamine was shown to have longer-term efficacy, in a study where ketamine plus the regular antidepressant helped people stay in stable remission 16 weeks into treatment. Relief from TRD with ketamine happens rapidly. Instead of waiting for an SSRI to hopefully provide some relief over the course of weeks, people who are suffering under the crushing weight of depression can start to feel the benefits of ketamine within about 40 minutes. This is a discussion that should include your primary care doctor, your mental health provider, and any other health care professionals who care for you. It's important to remember that ketamine isn't a first-option treatment for depression, and it is generally used only when other, more longstanding treatments haven't been effective. It is not thought to be curative; rather, it improves symptoms for a certain amount of time. It is easier to say who isn't appropriate for ketamine treatment, based on the side effects. Independent, outpatient ketamine clinics are popping up all over the place. It is estimated that there are currently hundreds to thousands of these clinics — almost all of which were established in when ketamine was approved for TRD. Typically, these clinics are for-profit enterprises that are staffed by some combination of either a psychiatrist or an anesthesiologist who can administer the infusion , a nurse, a social worker, and of course the businesspeople who make it all work. In writing this piece, I called several ketamine clinics, posing as a patient, to investigate what would be involved in receiving ketamine therapy. Most of them seemed as if they would provide ketamine for me without any major hurdles, after an introductory medical interview by a nurse or a social worker. A few clinics required communication or a diagnosis from my psychiatrist — and this seemed quite sensible. The clinics operate on a fee-for-service arrangement, so you would pay out of pocket, as insurance rarely covers this treatment. Thankfully, today, there are a number of other options and some promising approaches for the future. A promising experimental neuromodulation technique, deep brain stimulation, uses implanted bilateral electrodes in certain brain areas that—when connected to a pulse generator—stimulate electrical impulses that control abnormal brain activity. Surgical implantation takes about four hours and a second surgery is needed to connect the electrodes to the generator. The neurologist programs the pulse generator, and the patient can control the electrical impulses with an external remote control. A study, conducted at the University of California San Francisco,² found that the discovery of a neural biomarker — a specific pattern of brain activity that indicated the onset of depressive symptoms—led to the creation of a customized DBS device that responded only when that pattern was recognized. This device then stimulated a different part of the brain circuit, leading to almost immediate eradication of depression. Note: Biomarker is short for biological marker, a biological response that can be measured. Blood pressure is an example of a biomarker. In rTMS , treatment is aimed at the parts of the brain which cause depression and regulate executive functions mental processes needed for us to plan, focus attention, remember instructions, and juggle multiple tasks. An electromagnetic coil is placed over the scalp and focused pulses are discharged to stimulate cortical neurons. Four to six weeks of once-daily sessions are required to treat depression. No anesthesia is needed and there are no cognitive side effects such as memory loss. A study at the Stanford University School of Medicine³ examined SAINT, Stanford accelerated intelligent neuromodulation therapy , a new type of magnetic brain stimulation, requiring five consecutive days of ten minute sessions, with breaks in between, that pinpointed an overactive subregion of the brain related to depression. The FDA cleared SAINT in September for treatment-resistant major depressive disorder; the technology is expected to be commercially available in late on a limited basis by prescription only. In ECT , a muscle relaxant is administered, electrodes are placed bilaterally or unilaterally on the scalp. Under general anesthesia, low-intensity electrical currents are passed through the brain to trigger a grand mal seizure. The procedure, in use since the late s, resets brain function to decrease or eradicate depression. It can cause memory loss and other cognitive impairments, although most are reversible once treatment has ended. A patient typically receives two to three weekly treatments and usually requires between six and 18 total sessions. Each session lasts about an hour and is done on an outpatient basis. Maintenance sessions may be recommended. A review of studies on the efficacy of ECT for depression concluded "there is consistent evidence that there are low to mild side effects and most of them are transient and remit usually before the second treatment" and "there is a low relapse rate compared to other treatments. Having TRD is nothing to laugh about. The effects lasted two to four weeks. The lower concentration was just as effective as the higher one used in Phase 1 trials, but with fewer side effects such as sedation and nausea. Nitrous oxide is an antagonist inhibitor of the NMDA receptor, as is ketamine , currently one of the most promising treatments for TRD, although further, larger studies are needed. NMDA receptors play a critical role in depression. The antidepressant properties of NMDAR-antagonists are attributed to their ability to affect neurotransmitters that are involved in mood regulation. Researchers hope a better understanding of NDMAR antagonists will lead to new uses in TRD. One meta-analysis, investigating the effectiveness of psychotherapy for TRD, found that adding psychotherapy to treatment as usual TAU provided better outcomes. The vagus nerve originates in the brainstem and extends through the neck and all the way down to the abdomen. You've heard of the gut-brain axis, right? Well, the vagus nerve is largely responsible for communication through the human body. Vagus nerve responsibilities include digestion, heart rate, and respiratory rate. Certain reflexes such as swallowing, vomiting, coughing, and sneezing are also controlled by the vagus nerve. Along with ECT and rTMS, vagus nerve stimulation is an FDA-approved neurostimulation technique for TRD. In an outpatient procedure under general anesthesia, an implantable pulse generator is surgically inserted under the skin of the chest and connected to one of the vagus fibers in the neck. The repeatedly stimulated vagus nerve sends impulses to certain regions of the brain involved with emotion, memory, and behavior. Imaging studies have shown that activity in the thalamus and cortex region of the brain in patients with depression is altered by VNS therapy. The treatment also seems to help to modulate the concentration of neurotransmitters that affect mood. One meta-analysis found that VNS, when used in addition to the usual standard of care, caused improvement of TRD for up to 24 months with minimal safety issues. Transcutaneous vagus nerve stimulation tVNS can also be used to address TRD. It's a less invasive procedure that is similar to traditional VNS. With tVNS, surface electrodes are attached to the body that target the vagus nerve. |

| How to Manage Treatment-Resistant Depression | Esketamine itself also works differently to traditional antidepressants; instead of targeting certain neurotransmitters in the brain, such as serotonin and norepinephrine, it uniquely targets the glutamate system, which is the major excitatory neurotransmitter in the brain. Essentially, esketamine binds to the inhibitory neurons in the brain, causing net excitation in the areas of the brain that are part of the depression circuit. Spravato is a nasal spray to be used in conjunction with an oral antidepressant for the treatment of depression in adults who have tried other antidepressant medications but have not benefited from them — a. a treatment resistant depression. As well as esketamine, Auvelity is another recently approved antidepressant, after receiving FDA approval just last year , and is a combination of dextromethorphan — best known as a cough suppressant — and bupropion — used to treat major depressive disorder and facilitate tobacco cessation. Auvelity is also thought to provide faster-acting relief than traditional antidepressants and could be especially effective for people with treatment resistant depression, providing relief within one week of commencement. Currently, in phase 3 of clinical development for both major depressive disorder and postpartum depression, if approved, Zuranolone could be a potentially groundbreaking new antidepressant. This is because, not only is it fast-acting — some people may feel better within two or three days — but only a 2-week course is required, with the effects being sustained well beyond the period of those two weeks. This takes away the burden of having to take antidepressants chronically, and also helps to minimize any potential side effects. Mona Kotecha, M. The GABA system is a pathway that is important in tampering down messaging because the brain is really a balance of excitation and inhibition; so excitatory signaling and inhibitory signaling. Zuranolone is currently under review by the FDA after Biogen filed a new drug application for it. On top of taking antidepressants, it is important to remember that seeking psychological support is also extremely effective for people suffering from depression, as medication alone might not work if the core issues of their depression are not dealt with or made manageable. Kotecha said that Biogen strongly believes there is an urgent need for innovative therapies for all types of depression. But the recent approvals and research around new antidepressants certainly seems promising, and they may well provide the answer to helping those suffering with treatment resistant depression.

Treatment-resistant depression: the challenges Studies have shown that about one-third of people suffering from depression do not respond to current medications, with standard treatments either not helping at all, or improving symptoms temporarily, only for them to keep on returning. How do new antidepressants differ from more traditional types? Blood pressure is an example of a biomarker.

This fast-growing branch of precision medicine sometimes called individualized medicine uses DNA sequencing and analysis of specific alleles variant forms of genes within the DNA, for information about how the body will respond to medication in advance of trying it. Based on the results of the DNA test a physician could use the information to inform their prescribing decision. For example, starting with an SNRI rather than an SSRI. More research is needed to determine how these tests might one day help with selection of the most effective treatment for a specific person. The FDA has deemed psychedelics a " breakthrough therapy " for TRD meaning the approval process is expedited. In some clinical trials, psilocybin aka magic mushrooms is administered via capsule to a patient.

| Unipolar depression in adults: Choosing treatment for resistant depression - UpToDate | Anxiety disorders are one of the most common disorder types associated with treatment-resistant depression. The two disorders commonly co-exist, and have some similar symptoms. Some studies have shown that patients with both MDD and panic disorder are the most likely to be nonresponsive to treatment. Substance abuse may also be a predictor of treatment-resistant depression. It may cause depressed patients to be noncompliant in their treatment, and the effects of certain substances can worsen the effects of depression. Other psychiatric disorders that may predict treatment-resistant depression include attention deficit hyperactivity disorder , [5] personality disorders , obsessive compulsive disorder , and eating disorders. Some people who are diagnosed with treatment-resistant depression may have an underlying undiagnosed health condition that is causing or contributing to their depression. Endocrine disorders like hypothyroidism , Cushing's disease , and Addison's disease are among the most commonly identified as contributing to depression. Others include diabetes , coronary artery disease , cancer , HIV , and Parkinson's disease. Another factor is that medications used to treat comorbid medical disorders may lessen the effectiveness of antidepressants or cause depression symptoms. People with depression who also display psychotic symptoms such as delusions or hallucinations are more likely to be treatment resistant. Another depressive feature that has been associated with poor response to treatment is longer duration of depressive episodes. There are three basic categories of drug treatment that can be used when a medication course is found to be ineffective. One option is to switch the patient to a different medication. Another option is to add a medication to the patient's current treatment. This can include combination therapy : the combination of two different types of antidepressants , or augmentation therapy : the addition of a non-antidepressant medication that may increase the effectiveness of the antidepressant. Increasing the dosage of an antidepressant is a common strategy to treat depression that does not respond after adequate treatment duration. Practitioners who use this strategy will usually increase the dose until the person reports intolerable side effects , symptoms are eliminated, or the dose is increased to the limit of what is considered safe. Switching people with treatment-resistant depression to a different class of antidepressants may also be effective. People who are non-responsive after taking an SSRI may respond to moclobemide or tricyclic antidepressants , bupropion or an MAOI. Primarily dopaminergic or norepinephrine releasing stimulants, in low doses, have been used especially in the past, or in conjunction with a multidisciplinary therapy approach, although more targeted and "mild" agents, including modafinil and atomoxetine are considered first line [ by whom? When depression is related or co-morbid to an inattention disorder, often ADHD , then both can be carefully managed with the same first line stimulant medication, typically both methylphenidate and lisdexamfetamine. Medications that have been shown to be effective in people with treatment-resistant depression include lithium , liothyronine , benzodiazepines , atypical antipsychotics , and stimulants. Adding lithium may be effective for people taking some types of antidepressants; it does not appear to be effective in patients taking SSRIs. Liothyronine synthetic T 3 is a type of thyroid hormone and has been associated with improvement in mood and depression symptoms. Benzodiazepines may improve treatment-resistant depression by decreasing the adverse side effects caused by some antidepressants and therefore increasing patient compliance. Since the entry of olanzapine into psychopharmacology , many [ quantify ] psychiatrists have been adding low dose olanzapine to antidepressants and other atypical antipsychotics such as aripiprazole and quetiapine. Eli Lilly, the company that sells both olanzapine and fluoxetine individually, has also released a combination formulation which contains olanzapine and fluoxetine in a single capsule. Some low to moderate quality evidence points to success in the short term 8—12 weeks using mianserin or antipsychotics cariprazine , olanzapine , quetiapine or ziprasidone to augment antidepressant medications. However, stimulants have been shown to be effective for the unyielding depressed combined lacking addictive personality traits or heart problems. Ketamine has been tested as a rapid-acting antidepressant [18] for treatment-resistant depression in bipolar disorder , and major depressive disorder. A placebo randomized controlled trial evaluated the rapid antidepressant effects of the psychedelic ayahuasca in treatment-resistant depression with positive outcome. Electroconvulsive therapy is generally only considered as a treatment option in severe cases of treatment-resistant depression. It is used when medication has repeatedly failed to improve symptoms, and usually when the patient's symptoms are so severe that they have been hospitalized. Electroconvulsive therapy has been found to reduce thoughts of suicide and relieve depressive symptoms. rTMS repetitive transcranial magnetic stimulation is gradually becoming recognised as a valuable therapeutic option in treatment-resistant depression. A number of randomised placebo-controlled trials have compared real versus sham rTMS. In , the Food and Drug Administration FDA approved esketamine Spravato for treatment-resistant depression. Doctors deliver this nasal spray to individuals in an office or clinic, and it quickly reduces symptoms in about half of people. However, esketamine has significant side effects, including high blood pressure and dissociative symptoms. Some people have success with psilocybin , the psychedelic in hallucinogen mushrooms. Its mechanism of action may be somewhat similar to first-line traditional medications, such as SSRIs, which increase levels of serotonin in the brain. Researchers believe inflammation plays a role in treatment-resistant depression, so they may use anti-inflammatory drugs to treat it. Medications in this category may include cyclooxygenase-2 inhibitors COX-2 inhibitors such as celecoxib Celebrex and infliximab Remicade. Older research from notes that a combination of risk factors contribute to treatment-resistant depression, including:. Older research indicates that unlike normal depression — which responds to typical treatment interventions — treatment-resistant depression manifests in:. If you or someone you know is having thoughts of suicide, a prevention hotline can help. The Suicide and Crisis Lifeline is available 24 hours a day at During a crisis, people who are hard of hearing can use their preferred relay service or dial then Find more links and local resources. According to research from , more than one-third of people with treatment-resistant depression go into remission. The remainder have residual symptoms. One of these is an older clinical trial that investigated the effect of electroconvulsive therapy in people with MDD. According to a study , experts do not fully understand how remission works. They still have much to learn about helping people reach and maintain remission. A diagnosis of treatment-resistant depression means a person has tried two different antidepressants that did not provide sufficient symptom reduction. About one-third of people with MDD have treatment-resistant depression. A doctor may recommend adding or changing medications, psychotherapy, electroconvulsive therapy, or new or novel medications. TMS is a noninvasive therapy that doctors may recommend for people with treatment-resistant depression. Learn more. Severe depression means depression symptoms are often bad enough that they interfere with many daily functions. Psychedelic therapy is the use of plants and compounds that can induce hallucinations to treat mental health diagnoses, such as depression and PTSD…. Depression is a lifelong mental health condition. There is no cure for depression, but many different treatments are available to manage the symptoms. Prozac and Zoloft are two types of antidepressant. In this article, we compare the uses, dosages, and side effects of the two drugs. In light of the serious nature of treatment-resistant depression and the need for patients to receive some form of treatment, all patients in these studies started a new oral antidepressant at the time of randomization and the new antidepressant was continued throughout the trials. The primary efficacy measure was the change from baseline on a scale used to assess the severity of depressive symptoms. In one of the short-term studies, Spravato nasal spray demonstrated statistically significant effect compared to placebo on the severity of depression, and some effect was seen within two days. The two other short-term trials did not meet the pre-specified statistical tests for demonstrating effectiveness. In the longer-term maintenance-of-effect trial, patients in stable remission or with stable response who continued treatment with Spravato plus an oral antidepressant experienced a statistically significantly longer time to relapse of depressive symptoms than patients on placebo nasal spray plus an oral antidepressant. The most common side effects experienced by patients treated with Spravato in the clinical trials were disassociation, dizziness, nausea, sedation, vertigo, decreased feeling or sensitivity hypoesthesia , anxiety, lethargy, increased blood pressure, vomiting and feeling drunk. Patients with unstable or poorly controlled hypertension or pre-existing aneurysmal vascular disorders may be at increased risk for adverse cardiovascular or cerebrovascular effects. Spravato may impair attention, judgment, thinking, reaction speed and motor skills. Patients should not drive or operate machinery until the next day after a restful sleep. Spravato may cause fetal harm and women of reproductive potential should consider pregnancy planning and prevention; women should not breastfeed while being treated.

Antidepressant for treatment-resistant depression -
The new findings are published March 3 in The New England Journal of Medicine and are to be presented that same day by Eric J. Lenze, MD — principal investigator and head of the Department of Psychiatry at Washington University — and colleagues at the annual meeting of the American Association for Geriatric Psychiatry in New Orleans.
Consequently, some doctors switch such patients to different antidepressants in the pursuit of finding one that works, while other physicians may prescribe another class of drugs to see if a combination of medications helps.
Both strategies have been recommended by experts as options for older adults with treatment-resistant depression. However, the new study was designed to help determine which strategy is most effective.
We found that adding aripiprazole led to higher rates of depression remission and greater improvements in psychological well-being — which means how positive and satisfied patients felt — and this is good news. Treatment-resistant depression is no more or less common in older people than younger people, but because it seems to accelerate cognitive decline, identifying more effective ways to treat it is very important.
Lenze, along with colleagues at Columbia University, UCLA, the University of Pittsburgh and the University of Toronto, studied people, ages 60 and older, with treatment-resistant depression, meaning their depression had not responded to at least two different antidepressant medications.
The researchers evaluated strategies commonly used in clinical practice to help alleviate treatment-resistant depression in older patients and designed the study to have two distinct phases.
This Cochrane review included 10 randomized controlled trials with 2, patients. One study involved switching medications, whereas the others augmented therapy with a second medication.
The most common baseline antidepressant was fluoxetine Prozac. Most studies had 12 weeks or less of follow-up, but one included follow-up at one year.
Because changes in average depression scores are difficult to interpret, studies reported more clinically oriented measures. The remission rate was defined as the number of participants with depression scores reduced below a threshold that demonstrates resolution of depression.
Studies also reported dropout rates for any reason as a measure of treatment harm. One small, low-quality study demonstrated that switching from fluoxetine to mianserin a tetracyclic antidepressant not available in the United States did not improve depression scores, response rates, or remission rates.
Two European studies evaluated the benefit of augmenting fluoxetine therapy with another antidepressant. Augmentation with mianserin at a daily dosage of 60 mg increased both response and remission rates, without increasing drop-out rates.
Augmentation with mirtazapine Remeron , 30 mg daily, failed to improve depression symptoms, response rates, or remission rates after 12, 24, or 52 weeks. One study in which fluoxetine or citalopram Celexa was augmented with buspirone Buspar , 10 to 30 mg twice daily, showed no improvement in depression scores or response rates compared with placebo.
Augmentation with atypical antipsychotics had more evidence of benefit. Although use of quetiapine did not affect drop-out rates overall, dosages of mg daily increased dropouts, whereas lower dosages did not. Augmenting an SSRI or SNRI with cariprazine, 1 to 4. Guidelines from the Institute for Clinical Systems Improvement ICSI and the National Institute for Health and Care Excellence NICE recommend augmenting antidepressant therapy to manage treatment-resistant depression.
ICSI suggests augmentation with bupropion, buspirone, mirtazapine, thyroxine, stimulants, lithium, or atypical antipsychotics. Editor's Note: The NNTs, NNHs, and CIs reported in this Cochrane for Clinicians were calculated by the authors based on raw data provided in the original Cochrane review.
