# Isoxsuprine hydrochloride ## Overview Isoxsuprine hydrochloride is a vasodilator and beta-adrenergic agonist. ## Primary Indications Peripheral vascular disease, particularly intermittent claudication. Its efficacy is debated, and it is not a first-line therapy. ## Adult Dosing 10-20 mg orally 3-4 times daily. Maximum dose typically 80 mg daily. ## Pediatric Dosing No established pediatric dosing. ## Dose Adjustments No specific dose adjustments for hepatic or renal impairment are established. Use with caution. ## Contraindications * Hypersensitivity to isoxsuprine. * Should not be administered in the immediate post-operative period following surgery. * Concurrent administration with an epinephrine injection. ## Adverse Effects Common: Nausea, vomiting, gastric upset, dizziness, weakness, rash, flushing. Less Common: Hypotension, tachycardia, abdominal pain, pruritus. ## Key Drug Interactions * **Epinephrine:** Isoxsuprine antagonizes the vasoconstrictor and pressor effects of epinephrine. Avoid concurrent use. * **Antihypertensives:** May potentiate hypotensive effects. ## Monitoring * Monitor for therapeutic response (improvement in claudication symptoms). * Monitor for adverse effects, particularly cardiovascular ones (hypotension, tachycardia). ## Clinical Pearls * The clinical benefit of isoxsuprine in peripheral vascular disease is controversial and not well-supported by robust evidence. * It is generally considered a second or third-line agent, if used at all. * Lifestyle modifications (smoking cessation, exercise) and other evidence-based therapies should be prioritized. *** *Disclaimer: This information is intended for healthcare professionals.
