Phenylephrine Hydrochloride API is primarily used as a decongestant, to dilate pupils (mydriatic), and to increase blood pressure (cardiotonic), acting as a selective α1-adrenergic receptor agonist. Here's a more detailed breakdown of its uses:
- Decongestant: It's used to relieve nasal congestion and stuffiness caused by colds, allergies, and other breathing illnesses.
Mydriatic: It's used to dilate the pupils (enlarge them) before eye examinations, eye surgery, and to treat certain eye conditions.
Cardiotonic Agent: It can be used to treat hypotension (low blood pressure) that may occur during surgery or in situations like shock or anesthesia.
Mechanism of Action: Phenylephrine works by mimicking the effects of adrenaline (a hormone) and causing vasoconstriction (narrowing of blood vessels), which reduces swelling and congestion.
Formulations: Available in various forms, including nasal sprays, eye drops, and injectable solutions.
Over-the-counter: In many countries, phenylephrine hydrochloride is available as an over-the-counter medication for decongestion
