# Isoxsuprine Hydrochloride ## Overview Isoxsuprine hydrochloride is a vasodilator that acts as a beta-adrenergic agonist. It is thought to cause vasodilation by directly relaxing vascular smooth muscle. ## Primary Indications * Peripheral vascular disease, including intermittent claudication and Raynaud's disease. ## Adult Dosing * **Oral:** 10 mg to 20 mg three to four times daily. The dose may be increased to 40 mg four times daily if necessary. ## Pediatric Dosing * Safety and efficacy in pediatric patients have not been established. ## Dose Adjustments * No specific dose adjustments are recommended for renal or hepatic impairment. Caution is advised in patients with significant renal or hepatic disease due to potential for accumulation. ## Contraindications * Hypersensitivity to isoxsuprine. * Should not be administered intravenously. ## Adverse Effects * **Common:** Nausea, vomiting, gastric distress, dizziness, lightheadedness, flushing, weakness, blurred vision. * **Less Common:** Hypotension, tachycardia, rash, epigastric distress. ## Key Drug Interactions * **Antihypertensives:** Isoxsuprine may potentiate the effects of antihypertensive medications, leading to hypotension. * **Sympathomimetic agents:** Concurrent use may lead to additive cardiovascular effects. ## Monitoring * Blood pressure and heart rate should be monitored, especially at the initiation of therapy or with dose increases. * Assess for improvement in symptoms of peripheral vascular disease. ## Clinical Pearls * Efficacy in improving peripheral vascular disease has been debated, and its use is limited. * Oral administration is the only recommended route. * Avoid use in patients with recent arterial bleeding. **Disclaimer:** This information is intended for healthcare professionals.
