Beta-Blockers: All-for-One or One-for-All?

Primary Care Blog

Given a choice, most health plans will recommend a generic medication over a similar but branded one.  Of course, one has to remember that prior to the medication being made available as a generic, it was once sold only under a brand name.  In general, each pharmaceutical company wants to differentiate its me-too drug from everyone else's in the same drug class.  But those who handle the purse strings would like us to believe in class effect over drug effect, that they're all the same & replaceable.

The problem with this meta-analysis is that it's a meta-analysis.  It's not a direct comparison of each drug to its competitors.  This type of drug comparison study is rarely published because it's rarely funded & performed.  After all, which pharmaceutical company wants to take the chance that their already cleared & marketed drug will lose to a competitor.  So you have to leave it to the government to fund this type of study OR you look at the existing literature and run some tricky statistics.

Will I change my prescribing habits based upon a single study, especially a meta-analysis?  Probably not.  At least not until we find more of a trend as opposed to a possible fluke.  As always, discuss your concerns with your prescribing physician before stopping any medication.
