Some recently published studies suggest that taking selective serotonin reuptake inhibitors (SSRIs) may increase the risk of developing osteoporosis. A relationship between SSRIs and osteoporosis is biologically plausible because bone has serotonin receptors, and SSRI-treated mice have reduced bone mass.

A "Dear Colleague" letter from the UK's Committee on Safety of Medicines advised physicians, on the basis of unpublished data, not to use paroxetine (Paxil in the US; Seroxat in the UK) to treat children and adolescents with depression because of possible increased risk of suicidal behavior. This review describes the efficacy and safety of SSRIs in children.

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...

Since the introduction of fluoxetine (Prozac - Medical Letter, 30:45, 1988), bupropion (Wellbutrin - Medical Letter, 31:97, 1989), sertraline (Zoloft - Medical Letter, 34:47, 1992) and paroxetine (Paxil - this issue), the choice of an antidepressant has become more difficult. Should these widely prescribed new drugs replace tricyclic antidepressants such as amitriptyline (Elavil, and others), imipramine (Tofranil, and others), or nortriptyline (Aventyl, and others) for treatment of most patients with depression?

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?

Venlafaxine (Effexor, Effexor XR - Wyeth), an antidepressant that inhibits both norepinephrine and serotonin reuptake, was first approved by the FDA in 1993. It has been used mainly as a second-line agent for patients who have not responded to a selective serotonin reuptake inhibitor (SSRI). Some Medical Letter consultants have had the clinical impression that venlafaxine is more effective than an SSRI, particularly for patients with severe, classic depression (melancholia), and believe it should be considered a first-line drug (Treatment Guidelines from the Medical Letter 2003, 1:69). Is...

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.

Escitalopram (Lexapro - Forest), the active S-enantiomer of racemic citalopram (Celexa - Forest), a selective serotonin reuptake inhibitor (SSRI), was recently approved by the FDA for treatment of depression. The manufacturer plans to stop promoting Celexa in favor of Lexapro; Celexa will continue to be available for patients already taking it.

A selective serotonin reuptake inhibitor (SSRI) is generally used for initial treatment of major depressive disorder (MDD). A serotonin-norepinephrine reuptake inhibitor (SNRI), bupropion (Wellbutrin SR, and others), and mirtazapine (Remeron, and others) are reasonable alternatives. Improvement in symptoms can occur within the first two weeks of treatment with these drugs, but a substantial benefit may not be achieved for 4-8 weeks.

Citalopram hydrobromide (Celexa - Forest/Parke-Davis), a selective serotonin reuptake inhibitor (SSRI) available in Europe since 1989, has now been approved by the US Food and Drug Administration (FDA) for treatment of depression. It is being advertised as having a 'favorable side-effect profile.'
