# Isoxsuprine hydrochloride ## Overview Isoxsuprine hydrochloride is a vasodilator agent that is thought to relax vascular smooth muscle, leading to peripheral vasodilation. Its clinical efficacy is controversial. ## Primary Indications * Treatment of peripheral vascular disease (e.g., intermittent claudication, arteriosclerosis obliterans, Raynaud's disease). ## Adult Dosing * **Intermittent Claudication/Peripheral Vascular Disease:** 10-20 mg orally three to four times daily. * Dosing may be adjusted based on patient response and tolerance. ## Pediatric Dosing * There is no established pediatric dosing for isoxsuprine hydrochloride. ## Dose Adjustments * No specific dose adjustments are routinely recommended for renal or hepatic impairment, but caution should be exercised and doses may need to be reduced based on clinical assessment and patient tolerance. ## Contraindications * Hypersensitivity to isoxsuprine hydrochloride. * Use in patients with congenital heart disease. * Use in patients who require a more rapid increase in blood pressure. ## Adverse Effects * **Common:** Hypotension, tachycardia, dizziness, flushing, nausea, vomiting, abdominal distress, rash. * **Less Common:** Weakness, nervousness, drowsiness. ## Key Drug Interactions * **Antihypertensives:** Isoxsuprine may potentiate the hypotensive effects of antihypertensive medications. * **Epinephrine:** Concomitant administration with epinephrine may antagonize the vasodilating effects of isoxsuprine. ## Monitoring * Blood pressure and heart rate. * Signs and symptoms of peripheral vascular disease. * Patient tolerance to the medication. ## Clinical Pearls * The effectiveness of isoxsuprine in treating peripheral vascular disease is not well-established and remains controversial. * Administer with food to minimize gastrointestinal upset. * Advise patients to avoid activities requiring mental alertness until they know how the drug affects them, as it may cause dizziness or drowsiness. *** *Disclaimer: This information is intended for healthcare professionals.
