# Isoxsuprine Hydrochloride
## Overview
Isoxsuprine hydrochloride is a vasodilator that acts primarily on vascular smooth muscle, causing relaxation and vasodilation.
## Primary Indications
* Peripheral vascular disease (e.g., arteriosclerosis obliterans, intermittent claudication, Buerger's disease).
* Cerebrovascular insufficiency.
* Diabetic angiopathy.
## Adult Dosing
* **Typical Dose:** 10 mg to 20 mg orally three to four times daily.
* **Maximum Dose:** Not explicitly defined, but typically 20 mg four times daily. Dosing should be individualized based on patient response and tolerance.
## Pediatric Dosing
* There is no established pediatric dosing. Use in children is generally not recommended.
## Dose Adjustments
* **Renal Impairment:** No specific dose adjustments are routinely recommended, but caution may be warranted.
* **Hepatic Impairment:** No specific dose adjustments are routinely recommended, but caution may be warranted.
## Contraindications
* Hypersensitivity to isoxsuprine hydrochloride.
* Recent arterial bleeding.
* Tachyarrhythmias.
## Adverse Effects
* **Common:** Flushing, hypotension, dizziness, nausea, vomiting, abdominal distress, rash, weakness.
* **Less Common:** Palpitations, tachycardia, headache, drowsiness, blurred vision, nervousness.
## Key Drug Interactions
* **Antihypertensives:** Isoxsuprine may potentiate the effects of antihypertensive medications, leading to excessive hypotension.
* **Sympathomimetic agents:** Concomitant use may lead to additive cardiovascular effects (e.g., increased heart rate, blood pressure).
## Monitoring
* Blood pressure and heart rate.
* Symptoms of peripheral vascular disease.
* Signs of adverse effects.
## Clinical Pearls
* Isoxsuprine is generally not effective in relieving acute arterial occlusion.
* Optimal therapeutic effects may take several weeks to develop.
* Patients with glaucoma, diabetes, or severe atherosclerosis should be monitored closely.
