Minoxidil (U10858) is an orally administered vasodilator with hair growth stimulatory and antihypertensive effects.

Halothane (Anestan) is a nonflammable, halogenated, hydrocarbon anesthetic that provides relatively rapid induction with little or no excitement. Analgesia may not be adequate. NITROUS OXIDE is often given concomitantly. Because halothane may not produce sufficient muscle relaxation, supplemental neuromuscular blocking agents may be required.

Minoxidil sulfate (U-58838) is the active metabolite required to exert the vasodilatory and hair growing effects of minoxidil.

Tetraethylammonium bromide (TEA bromide) can selectively block potassium channels.

Nifedipine (Procardia) is a dihydropyridine calcium channel blocking agent. Nifedipine inhibits the transmembrane influx of extracellular calcium ions into myocardial and vascular smooth muscle cells, causing dilatation of the main coronary and systemic arteries and decreasing myocardial contractility. This agent also inhibits the drug efflux pump P-glycoprotein which is overexpressed in some multi-drug resistant tumors and may improve the efficacy of some antineoplastic agents.

Butamben (Butyl 4-aminobenzoate) is a long-duration local anesthetic used for the treatment of chronic pain.

Tannic acid (Gallotannic acid) is a novel hERG channel blocker.

Ursodeoxycholic acid (UDCA) can be used to dissolve gallstones and reduce cholesterol absorption.
