Which medications have consistently replicated randomized placebo-controlled trial evidence of efficacy in treating symptoms that are unresponsive to sertraline or paroxetine? Take the quiz and learn more.
The correct answer is E. None of the above
Only 2 medications have FDA indications for PTSD: paroxetine and sertraline. Some treatment guidelines recommend these or other antidepressants, including fluoxetine and venlafaxine, as equivalently first choice with focused CBT.1 Others regard focused CBT as having better evidence and suggest antidepressants only when therapy has failed or is not available, or in cases of severe depression.1-5 This reflects a number of negative randomized clinical trials (RCTs) with SSRIs, and small-to-moderate effect sizes relative to trauma-focused cognitive-behavioral therapy. It is important to note that many patients remain symptomatic and functionally impaired despite standard treatments and require alternative interventions.
There are medications with expert recommendations against their use (benzodiazepines), with uniformly negative RCTs (divalproex, bupropion, guanfacine, tiagabine), or with a mixture of both positive and negative evidence (fluoxetine, mirtaza¬pine, risperidone and olanzapine augmentation of antidepressants, topiramate). Furthermore, some commonly used pharmacologic agents have not been subject to RCTs in PTSD (citalopram, escitalopram, gabapentin, clonidine, lithium), nor have many newer agents such as levomilnacipran, milnacipran, vilazodone, vortioxetine, lurasidone, iloperidone, cariprazine, and brexpiprazole. Given the challenges in helping people with treatment-resistant PTSD, it was not surprising to find an impressive variety of alternative pharmacologic agents that have shown benefit in at least some treatment-resistant patients
