American Urological Association: 5-ARI, alpha-blocker differ in number of BPH-related complications
The 5-alpha-reductase inhibitor dutasteride is associated with markedly lower BPH-related complication rates than the alpha-blocker tamsulosin, according to analysis of 2 large trials.
Key Points
The 5-alpha-reductase inhibitor dutasteride (Avodart) is associated with markedly lower BPH-related complication rates than the alpha-blocker tamsulosin (Flomax), according to a post-hoc analysis of 2 large clinical trials of these agents presented at the American Urological Association annual meeting in Washington, DC.
The data were presented by lead author Claus G. Roehrborn, MD, of the University of Texas Southwestern Medical Center, Dallas.
The rates of acute urinary retention (AUR) and BPH-related surgery were compared in the treatment arms of the CombAT (Combination of Avodart and Tamsulosin) and REDUCE (Reduction by Dutasteride of Prostate Cancer Events) studies. These rates were compared among subgroups of men with the same prostate volume and International Prostate Symptom Score (IPSS).
The post-hoc analysis focused on men with an IPSS of 12 or greater at screening and a baseline prostate volume of 30 mL to 80 mL.
The rate of AUR/BPH-related surgery was significantly lower in all dutasteride arms compared with tamsulosin monotherapy or placebo. The rates of AUR/BPH-related surgery were:
The rates of AUR/BPH-related surgery for the dutasteride groups were relatively stable when stratified by prostate volume, but in the non-dutasteride groups, the rates more than doubled when comparing smaller to larger prostate volumes.
Over 4 years, the rates of serious BPH complications approached 20% in men with the largest prostates-60 mL to less than 80 mL-in the men randomly assigned to tamsulosin monotherapy (17.4%) and placebo (19.7%).
"Dutasteride, with or without tamsulosin, reduced the rate of these complications to 2.9%–5.4% across the spectrum of the prostate volume categories," said Dr Roehrborn.
Coalition promotes important acetaminophen dosing reminders
November 18th 2014It may come as a surprise that each year Americans catch approximately 1 billion colds, and the Centers for Disease Control and Prevention estimates that as many as 20% get the flu. This cold and flu season, 7 in 10 patients will reach for an over-the-counter (OTC) medicine to treat their coughs, stuffy noses, and sniffles. It’s an important time of the year to remind patients to double check their medicine labels so they don’t double up on medicines containing acetaminophen.
Support consumer access to specialty medications through value-based insurance design
June 30th 2014The driving force behind consumer cost-sharing provisions for specialty medications is the acquisition cost and not clinical value. This appears to be true for almost all public and private health plans, says a new report from researchers at the University of Michigan Center for Value-Based Insurance Design (V-BID Center) and the National Pharmaceutical Council (NPC).
