# Isoxsuprine Hydrochloride
## Overview
Isoxsuprine hydrochloride is a peripheral vasodilator. Its exact mechanism of action is not fully understood, but it is thought to relax vascular smooth muscle, leading to vasodilation.
## Primary Indications
* Treatment of peripheral vascular disease, such as intermittent claudication and arteriosclerosis obliterans.
* May be used as an adjunct in the treatment of cerebrovascular insufficiency.
## Adult Dosing
* **Typical Dose:** 10-20 mg orally 3-4 times daily.
* **Maximum Dose:** Not well-established, but doses exceeding 20 mg per administration are generally not recommended.
## Pediatric Dosing
There is no established pediatric dosing for isoxsuprine hydrochloride. Use is generally not recommended in this population due to lack of data.
## Dose Adjustments
No specific dose adjustments are recommended for renal or hepatic impairment, but caution is advised, and lower doses may be considered due to potential for accumulation.
## Contraindications
* Hypersensitivity to isoxsuprine hydrochloride.
* Use with extreme caution in patients with hypotension or tachycardia.
## Adverse Effects
* **Common:** Hypotension, dizziness, flushing, nausea, vomiting, abdominal distress, rash, weakness.
* **Less Common/Serious:** Tachycardia, palpitations, blurred vision, drowsiness, gastrointestinal upset.
## Key Drug Interactions
* **Antihypertensives:** Isoxsuprine may potentiate the hypotensive effects of antihypertensive medications.
* **Epinephrine:** May antagonize the vasodilating effects of isoxsuprine.
## Monitoring
* Blood pressure and heart rate.
* Signs and symptoms of peripheral vascular disease.
* Adverse effects.
## Clinical Pearls
* Isoxsuprine has shown limited efficacy in clinical trials for its primary indications and is not widely recommended by many professional guidelines.
* Effectiveness can vary significantly between individuals.
* Administration with food may help reduce gastrointestinal upset.
