# Isoxsuprine hydrochloride ## Overview Isoxsuprine hydrochloride is a vasodilator. Its exact mechanism of action is not fully understood but is believed to involve direct relaxation of vascular smooth muscle, leading to vasodilation and improved peripheral circulation. ## Primary Indications * Peripheral vascular disease (e.g., intermittent claudication, Burger's disease) to improve blood flow. * Arteriospasm and its sequelae. ## Adult Dosing * **Oral:** 10-20 mg by mouth 3 to 4 times daily. * **Maximum Daily Dose:** Not clearly defined, but typically 80 mg per day. Doses may be adjusted by the prescriber based on patient response and tolerance. ## Pediatric Dosing * There is no established pediatric dosing for isoxsuprine hydrochloride. Its use in pediatric patients is generally not recommended. ## Dose Adjustments * **Renal Impairment:** No specific guidelines. Use with caution and monitor for adverse effects. * **Hepatic Impairment:** No specific guidelines. Use with caution and monitor for adverse effects. ## Contraindications * Hypersensitivity to isoxsuprine. * Use in patients with congenital heart disease or those requiring surgical intervention for peripheral vascular disease. ## Adverse Effects * **Common:** Flushing, gastric distress, nausea, vomiting, dizziness, weakness, hypotension. * **Less Common:** Tachycardia, palpitations, skin rash, epigastric distress. ## Key Drug Interactions * **Antihypertensives:** May potentiate hypotensive effects. Monitor blood pressure closely. * **Other Vasodilators:** Additive hypotensive effects may occur. ## Monitoring * Blood pressure and heart rate. * Signs and symptoms of peripheral vascular disease (e.g., claudication distance, skin temperature, color). * Signs of adverse effects. ## Clinical Pearls * Isoxsuprine is generally considered to have limited efficacy in treating peripheral vascular disease and is often not a first-line agent. * Treatment should be discontinued if no appreciable improvement is observed after a reasonable trial period. * Avoid administration immediately after meals to minimize gastric distress. *** *This information is intended for clinical professionals. Always verify current prescribing information and consult with a qualified healthcare provider before making any treatment decisions.*
