🔬 How This Medicine Works (Pharmacology)
Pharmacokinetics
How It Works
Chlorpheniramine Maleate is a first-generation antihistamine that competitively blocks histamine H1 receptors, thereby preventing histamine-mediated allergic responses such as vasodilation, increased vascular permeability, and sensory nerve stimulation. Paracetamol acts primarily in the central nervous system by inhibiting prostaglandin synthesis, which leads to reduction of fever and pain. The combination provides both antihistaminic and analgesic-antipyretic effects.
