Celecoxib shows similar rates of recurrent bleeding to diclofenac plus omeprazole
April 1st 2003Two options are available for patients requiring treatment for arthritis who are at risk for ulcer disease: nonsteroidal anti-inflammatory drugs (NSAIDs) that are selective for cyclooxygenase-2 (COX-2) or the combination of a non-selective NSAID with a proton-pump inhibitor. A recent study of representative members from these therapeutic classes has offered findings that the two alternatives are statistically similar in their efficacy with respect to the prevention of recurrent ulcer bleeding.Celecoxib, a COX-2-selective NSAID, was given to 144 patients through random assignment. Another group of patients (N=143) were randomly assigned to receive a combination of diclofenac (a nonselective NSAID) plus omeprazole (a proton-pump inhibitor) during the 6-month trial.

Inhaled corticosteroids may carry less risk of BMD reduction in postmenopausal women
April 1st 2003Corticosteroid therapy is an effective treatment for asthma sufferers, but the use of systemic corticosteroids is known to increase the risk of osteoporotic fractures. A recent study published in the Journal of Allergy and Clinical Immunology suggests that moderate doses of inhaled corticosteroids (ICs) carry less risk than traditional oral corticosteroid (OC) therapy with respect to reduction of bone mineral density (BMD) in postmenopausal women. This assertion is based on the premise that the lowest daily dose of IC sufficient to control the patient's asthma is used.

Enfuvirtide: The first fusion inhibitor for the treatment of patients with HIV-1 infection (PDF)
April 1st 2003Enfuvirtide (Fuzeon, Roche/Trimeris) is the first member of a unique class of antiretrovirals known as the fusion inhibitors to gain FDA approval for the treatment of human immunodeficiency virus type-1 (HIV-1) infection. Enfuvirtide is indicated for use in combination with other antiretroviral agents in the treatment of HIV-1 infection in treatment-experienced patients with evidence of HIV-1 replication despite ongoing antiretroviral therapy. Phase 3 trials demonstrated that adding enfuvirtide 90 mg twice daily to an optimized background regimen chosen with genotypic and phenotypic resistance testing improved the surrogate end points of HIV ribonucleic acid (RNA) levels, CD4 cell counts, and the proportion of patients reaching clinically undetectable HIV RNA levels (<400 and <50 copies/mL) through 24 weeks. Enfuvirtide?s efficacy in treatment-experienced patients when added to an optimized background regimen makes it a promising choice for salvage therapy. Further studies will be required to support enfuvirtide?s use in treatment-naïve patients.

When it comes to sheer inspiration, Rocky Balboa doesn't have anything on Dr. Edson Bueno. Boxers always have a "puncher's chance" to land a knockout blow, but what chance does a poor -- and poorly educated -- Brazilian boy have of becoming the leader of his nation's biggest health plan?

Vardenafil (Levitra, Bayer AG/GlaxoSmithKline) is a selective inhibitor of phosphodiesterase 5 (PDE5) currently under review by FDA for the treatment of erectile dysfunction (ED). If approved, vardenafil will become the third PDE5 inhibitor to be marketed in the United States and the fourth oral agent approved for the treatment of ED. Vardenafil has been studied in subjects of various ages (<45 and >65 years of age), with different etiologies and different baseline severity of ED. Studies evaluating vardenafil have determined it to be safe and effective at doses of 5 mg to 40 mg, including subjects with diabetes mellitus and subjects who have undergone radical prostatectomy. Vardenafil has a pharmacokinetic profile similar to that of sildenafil (Viagra, Pfizer). The drug appears to be well tolerated. In clinical trials, headache, dyspepsia, and flushing were the most common adverse effects reported by subjects taking vardenafil. No adverse hemodynamic or visual effects have been reported during clinical trials of vardenafil; however, further investigation, including post-marketing surveillance, will be required. Further research and clinical experience with the newer PDE5 inhibitors (vardenafil and tadalafil [Cialis, Lilly/ICOS]) will be needed before their roles in the treatment of ED can be determined.

New insights into the treatment of pulmonary arterial hypertension (PDF)
March 1st 2003Pulmonary arterial hypertension (PAH) is a progressive, debilitating disorder associated with poor quality of life and shortened life span. For many years, medical therapy consisted of calcium channel blockers, warfarin, supplemental oxygen, and digitalis glycosides. A better understanding of the pathophysiology of PAH has led to the recent development of effective treatments for this disorder. Therapeutic agents target the pathophysiologic mechanisms of PAH: pulmonary vasoconstriction, pulmonary vascular remodeling, and in situ thrombosis. With better understanding of the pathogenesis of PAH, recent advances in pharmacotherapy have been introduced for the treatment of PAH. Data are presented on efficacy and safety of newer approved and investigational agents: prostacyclin analogues, oral endothelin antagonists, and phosphodiesterase 5 inhibitors.

Atomoxetine, a norepinephrine reuptake inhibitor, is the first nonstimulant agent approved for the treatment of ADHD (Strattera, Lilly). It has been approved for use in pediatric and adult patients. Atomoxetine improves ADHD symptom severity versus placebo, as evaluated by the ADHD Rating Scale (ADHD RS), and its efficacy appears comparable to immediate-release methylphenidate. Atomoxetine requires dosage titration and may be administered once or twice daily. Common side effects seen in both pediatric and adult patients include nausea, decreased appetite, and dizziness. Dosage adjustments are necessary for patients receiving atomoxetine and cytochrome P450 2D6 inhibitors. Based on average wholesale price (AWP), atomoxetine is more costly than existing ADHD therapies. Atomoxetine provides an alternative ADHD therapy for patients who may fail or cannot tolerate conventional treatments.
