On this episode of the Real Life Pharmacology Podcast, we cover minoxidil pharmacology, adverse effects, drug interactions, and much more.

Minoxidil is a potent arterial vasodilator used in the treatment of hypertension and androgenetic alopecia.

The route of administration greatly impacts the drug’s safety profile. Oral minoxidil is typically reserved for refractory hypertension due to its strong systemic effects and associated risks.

Topical formulations (2% or 5%) are widely used for hair regrowth, offering local benefits with minimal systemic absorption.

Systemic minoxidil can result in fluid retention, tachycardia, and even pericardial effusion, often requiring co-administration with a diuretic and beta-blocker.
