Phenylephrine Hydrochloride + Chlorpheniramine MaleateThird Party Manufacturing in India

Phenylephrine Hydrochloride + Chlorpheniramine Maleate is a dual-action syrup combining a nasal decongestant with an antihistamine for the symptomatic relief of allergic rhinitis and the common cold.

Phenylephrine Hydrochloride is a selective alpha-1 adrenergic receptor agonist that constricts dilated arterioles in the nasal mucosa. By reducing blood flow to engorged nasal tissues, it decreases mucus production, relieves nasal stuffiness, and restores normal breathing through the nasal passages with minimal central nervous system stimulation. Chlorpheniramine Maleate is a first-generation alkylamine antihistamine that acts as a competitive antagonist at histamine H₁ receptors. By blocking histamine-mediated responses, it effectively controls sneezing, rhinorrhoea, nasal itching, and ocular symptoms associated with allergic rhinitis. Its additional anticholinergic properties further reduce excessive nasal and lacrimal secretions.

Together, Phenylephrine targets the vascular congestion component while Chlorpheniramine addresses the histamine-mediated allergic response, providing comprehensive relief from both nasal congestion and allergic symptoms in a single syrup formulation.

Phenylephrine Hydrochloride + Chlorpheniramine Maleate Syrup is indicated for the symptomatic relief of nasal congestion and allergic symptoms associated with the common cold, allergic rhinitis, sinusitis, and upper respiratory tract infections:

• Nasal Congestion: Phenylephrine provides rapid relief from nasal stuffiness, sinus congestion, and difficulty breathing through the nose by constricting blood vessels in the nasal mucosa.
• Sneezing and Rhinorrhoea: Chlorpheniramine effectively controls sneezing, runny nose, and nasal itching by blocking histamine H₁ receptors.
• Allergic Rhinitis: Manages both seasonal and perennial allergic rhinitis symptoms including nasal itching, congestion, and excessive mucous discharge.
