# Isoxsuprine Hydrochloride
## Overview
Isoxsuprine hydrochloride is a peripheral vasodilator. Its exact mechanism of action is not fully understood but is thought to involve direct relaxation of vascular smooth muscle.
## Primary Indications
* Peripheral vascular disease (e.g., arteriosclerosis obliterans, intermittent claudication, vasospastic states) to improve blood flow.
* Historically used for threatened premature labor, but this use is generally not recommended due to lack of efficacy and safety concerns.
## Adult Dosing
* **Peripheral Vascular Disease:** Typically 10-20 mg orally three to four times daily.
* Maximum dose: Not clearly established, but doses exceeding 40 mg daily are uncommon.
## Pediatric Dosing
* No established pediatric dosing. Use in children is generally not recommended.
## Dose Adjustments
* No specific dose adjustments are routinely recommended for hepatic or renal impairment, though caution is advised.
## Contraindications
* Use with extreme caution or avoid in patients with congenital heart defects, arrhythmias, or hypotension.
* Hypersensitivity to isoxsuprine.
## Adverse Effects
* **Common:** Flushing, dizziness, nausea, vomiting, abdominal distress, headache, weakness, rash.
* **Less Common:** Hypotension, tachycardia, palpitations, drowsiness, excitement.
## Key Drug Interactions
* **Antihypertensives:** Isoxsuprine may potentiate the hypotensive effects of antihypertensive medications.
* **Sympathomimetics:** May cause additive effects on heart rate and blood pressure.
## Monitoring
* Blood pressure and heart rate.
* Symptoms of peripheral vascular disease.
## Clinical Pearls
* Efficacy in treating peripheral vascular disease is controversial and often based on anecdotal evidence.
* Monitor for adverse effects, especially cardiovascular ones.
* Patients should be advised to avoid activities requiring mental alertness until they know how this medication affects them.
