A comparison of the newer treatment options for ADHD (PDF)January 1st 2003
Psychostimulant drugs have consistently demonstrated efficacy in the treatment of attention-deficit/hyperactivity disorder (ADHD). Innovative technology has fueled the development of novel release mechanisms and isolation of active enantiomer components with the hopes of enhancing the duration of action and improving the safety and effectiveness. As a result, several new stimulant agents have recently been added to the arsenal of ADHD treatment options. Formulary selection is complicated by the high costs and small but distinct differences among these agents. The five newest FDA-approved stimulant agents for the treatment of ADHD are detailed, and a brief summary of future treatment options, including a recently approved nonstimulant agent, is provided.
Duloxetine: An antidepressant that inhibits both norepinephrine and serotonin uptakeJanuary 1st 2003
Duloxetine is a reuptake inhibitor at serotonergic and noradrenergic neurons and appears to have low affinity for other neurotransmitter systems. In three published clinical trials in patients with MDD, duloxetine was well tolerated and more effective than placebo. Further study is needed to compare its efficacy with that of other antidepressants, to prospectively assess time to onset of antidepressant effect, and to clarify effects on somatic symptoms and potential adverse cardiovascular and sexual effects. Duloxetine is also under investigation for the treatment of stress urinary incontinence in women (trade name to be determined, comarketed by Lilly and Boehringer Ingelheim). Preliminary information suggests that duloxetine therapy reduces the number of incontinence episodes. Duloxetine has been deemed ?approvable? for the treatment of MDD and will be comarketed under the trade name Cymbalta by Eli Lilly and Company and Quintiles.
From the Stanley Conference: Options expand for bipolar disorderNovember 1st 2002
Studies presented at the Third European Stanley Foundation Conference on Bipolar Disorder in September in Freiburg, Germany, show two newer antipsychotics are each more effective than standard therapy for preventing mania relapse or reducing symptoms.
Aripiprazole: First of a new class of antipsychotics (PDF)November 1st 2002
Aripiprazole is an investigational atypical antipsychotic that received an approvable status from FDA in September 2002 for the treatment of schizophrenia. The decision on approval could be made as early as the end of this year. Aripiprazole offers a unique mechanism of action as a dopamine system stabilizer. Aripiprazole has been found to be effective in both short-term (4?6 wk) and long-term (26?52 wk) treatment trials. It appears to produce less hyperprolactinemia, weight gain, and extrapyramidal symptoms than other antipsychotics.
NEW WARNING: Clinicians alerted to Seroquel/Serzone confusionJuly 1st 2002
Confusion between two drugs with sound-alike proprietary names, the antipsychotic quetiapine fumarate (Seroquel, AstraZeneca) and antidepressant nefazodone HCl (Serzone, Bristol-Meyers Squibb) has prompted AstraZeneca to send a "Dear Healthcare Professional" letter warning of the potential mix-up.
Market share shift analysis identifies potential impact of atypical antipsychotic formulary addition on budgetJuly 1st 2002
Anoka Regional Treatment Facility, Anoka, MN-This 150-bed regional treatment facility was spending over half its annual budget on atypical antipsychotic medications. In an effort to better control rising drug class costs, a market share shift analysis of the products currently in use at the facility was conducted.
Part 2: Beyond depression: Evaluation of newer indications and off-label uses for SSRIs (PDF)June 1st 2002
In this final installment of this series, the authors focus on the use of SSRIs in alcohol dependence, chronic pain, eating disorders, premenstrual dysphoric disorder, and sexual dysfunction. For each condition, the authors examine how well clinical trial evidence supports the application, discuss dosing and safety considerations, and provide their recommendations on preferred and alternative SSRIs, based on the weight of the evidence.
Part one of a two-part series: Beyond depression: Evaluation of newer indications and off-label uses for SSRIs (PDF)May 1st 2002
Although selective serotonin reuptake inhibitors (SSRIs) are prescribed most often for depression disorders, they are increasingly being used to treat a variety of other conditions. In this article, the authors assess the evidence on anxiety disordersâ€”generalized anxiety disorder, obsessive-compulsive disorder, panic disorder, posttraumatic stress disorder, and social phobia. For each condition, they present the rationale for SSRI use, the degree of supportive clinical trial evidence, indication-specific dosing and safety considerations, and their recommendations for the preferred and alternative SSRIs.
