LOW DOSE DAILY ASPIRIN REDUCES TOPICAL MINOXIDIL EFFICACY IN ANDROGENETIC ALOPECIA PATIENTS.

Summary of "LOW DOSE DAILY ASPIRIN REDUCES TOPICAL MINOXIDIL EFFICACY IN ANDROGENETIC ALOPECIA PATIENTS."

Topical minoxidil is the only US FDA approved OTC drug for the treatment of androgenetic alopecia (AGA). Minoxidil is a pro-drug converted into its active form, minoxidil sulfate, by the sulfotransferase enzymes in the outer root sheath of hair follicles. Previously, we demonstrated that sulfotransferase activity in hair follicles predicts response to topical minoxidil in the treatment of AGA. In the human liver, sulfotransferase activity is significantly inhibited by salicylic acid. Low dose OTC aspirin (75mg-81mg), a derivative of salicylic acid, is used by millions of people daily for the prevention of coronary heart disease and cancer. It is not known whether oral aspirin inhibits sulfotransferase activity in hair follicles, potentially affecting minoxidil response in AGA patients. In this study, we determined the follicular sulfotransferase enzymatic activity following 14 days of oral aspirin administration. In our cohort of 24 subjects, 50% were initially predicted to be responders to minoxidil. However, following 14 days of aspirin administration, only 27% of the subjects were predicted to respond to topical minoxidil. To the best of our knowledge, this is the first study to report the effect of low dose daily aspirin use on the efficacy of topical minoxidil. This article is protected by copyright.

Medical and Biotech [MESH] Definitions

A potent direct-acting peripheral vasodilator (VASODILATOR AGENTS) that reduces peripheral resistance and produces a fall in BLOOD PRESSURE. (From Martindale, The Extra Pharmacopoeia, 30th ed, p371)

A non-steroidal anti-inflammatory agent that is less effective than equal doses of ASPIRIN in relieving pain and reducing fever. However, individuals who are hypersensitive to ASPIRIN may tolerate sodium salicylate. In general, this salicylate produces the same adverse reactions as ASPIRIN, but there is less occult gastrointestinal bleeding. (From AMA Drug Evaluations Annual, 1992, p120)

Asthmatic adverse reaction (e.g., BRONCHOCONSTRICTION) to conventional NSAIDS including aspirin use.
