Vilazodone (Viibryd – Forest), a selective serotonin reuptake inhibitor (SSRI) and partial 5-HT_1A receptor agonist, has been approved by the FDA for treatment of depression. It has been claimed to have no sexual side effects and not to cause weight gain.

Five different selective serotonin reuptake inhibitors (SSRIs) are promoted for treatment of depression and a sixth (fluvoxamine) for use in obsessive compulsive disorder. Which one should we prescribe for our patients?

Bipolar disorder is characterized by episodes of mania, hypomania, and depression. Recurrences of manic or (more frequently) depressive symptoms are common. About 15-20% of patients with bipolar disorder die by suicide.

Depression occurs in up to 20% of pregnant women, and the use of selective serotonin reuptake inhibitors (SSRIs) in these women has been increasing. Maternal depression has itself been associated with intrauterine growth problems and low birth weight, so the risks of exposure to antidepressants during pregnancy must be weighed against the risks of untreated depression, which also include self-harm, poor bonding and poor parenting. SSRIs available in the US for treatment of depression include citalopram (Celexa, and others), escitalopram (Lexapro), fluoxetine (Prozac, and others), paroxetine...

The FDA has required manufacturers of propoxyphene-containing products (Darvon, and others) to strengthen boxed warnings to include the potential for overdose.1 This action followed disclosure of fatal overdoses linked to propoxyphene-containing products taken alone or concurrently with other CNS depressants, including alcohol. Many of the overdoses occurred in patients with a history of emotional instability or suicide attempts. Accumulation of metabolites of propoxyphene can lead to central nervous system, cardiac and respiratory depression; convulsions and cardiotoxicity have occurred.A...

Cognitive behavioral therapy for insomnia (CBT-I) is recommended for initial treatment of chronic insomnia. CBT-I includes stimulus control, sleep education and hygiene, sleep restriction, relaxation training, and cognitive therapy. When CBT-I alone is not effective, pharmacologic treatment should be added.

Clomipramine (Anafranil - Ciba-Geigy), a tricyclic antidepressant, is now available for treatment of obsessive compulsive disorder (OCD) in accordance with the new US Food and Drug Administration (FDA) procedure for promising investigational drugs (FE Young et al, JAMA, 259:2267, 1988). In other countries, clomipramine has been widely used for many years for treatment of depression.

In 2011, the FDA asked the manufacturers of the selective serotonin reuptake inhibitor (SSRI) citalopram (Celexa, and generics) to lower the maximum daily dosage of the drug because of a dose-related increase in the QT interval. Since then, some of our readers have asked whether escitalopram (Lexapro, and generics), the active enantiomer of citalopram, could have the same effect.

In the short time since fluoxetine (Prozac - Lilly) first became available in the USA (Medical Letter, 30:45, 1988), it has become the most frequently prescribed of all antidepressants. Some recent reports, however, have questioned its safety.

Venlafaxine hydrochloride (Effexor - Wyeth-Ayerst) was recently approved by the US Food and Drug Administration for treatment of depression. An aminomethyl-benzyl- cyclohexanol, it is chemically related to bupropion (Wellbutrin).
