Metaoxedrin

Phenylephrine Hydrochloride, the active ingredient in Metaoxedrin, is a Alpha-1 adrenergic agonist presented as a injection solution for intravenous use. It treats acute hypotension, various forms of shock, and can be employed as a nasal decongestant in appropriate clinical settings.

GNH USA supplies Metaoxedrin as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals worldwide.

Phenylephrine Hydrochloride is an alpha‑1 adrenergic agonist used in conditions requiring rapid elevation of blood pressure.

Acute hypotension: raises systemic blood pressure to restore adequate organ perfusion. Septic shock: provides vasopressor support to maintain hemodynamic stability. Anesthetic‑induced hypotension: counteracts blood pressure drops during surgery. Nasal congestion (off‑label): reduces nasal mucosal edema through vasoconstriction.

Phenylephrine Hydrochloride may cause a range of adverse reactions, from mild to severe. Monitoring patients for any unexpected response is essential.

Common Side Effects: - Headache: mild to moderate discomfort often related to vasoconstriction. - Reflex tachycardia: compensatory increase in heart rate. - Nausea: transient gastrointestinal upset. - Tremor: fine muscle shaking.

Serious or Rare Side Effects: - Severe hypertension: abrupt, dangerous rise in blood pressure. - Myocardial ischemia: reduced heart muscle blood flow. - Arrhythmia: abnormal heart rhythm. - Allergic reaction: including anaphylaxis. - Tissue necrosis at injection site: due to intense vasoconstriction. - Peripheral ischemia: compromised blood flow to extremities.

Phenylephrine Hydrochloride requires careful clinical oversight to minimize risks.

Monitor blood pressure: obtain baseline values and observe continuously during infusion. Use cautiously in coronary artery disease: risk of myocardial ischemia. Avoid in severe hypertension: may exacerbate high blood pressure. Exercise caution in the elderly: increased sensitivity to vasoconstriction. Store at 2-8°C: keep refrigerated, protect from light, do not freeze or shake.

Phenylephrine Hydrochloride can interact with several drug classes, necessitating vigilance.

Major Interactions (Avoid): - MAO inhibitors: risk of hypertensive crisis. - Tricyclic antidepressants: additive vasoconstrictive effect. - Ergot alkaloids: potential severe vasospasm.

Moderate Interactions (Monitor Closely): - ACE inhibitors: may blunt blood pressure response. - Diuretics: can potentiate post‑infusion hypotension. - Calcium channel blockers: additive cardiovascular effects.
