What is Chlorphenamine Maleate ?

Usage
Function of Chlorphenamine Maleate
Chlorpheniramine is an H1 receptor antagonist, and its chemical structure belongs to hydrocarbon amines.
It can competitively block the histamine H1 receptor on the target cells of allergic reaction, so that histamine
cannot bind to the H1 receptor, thus inhibiting the allergic reaction caused by it. But chlorpheniramine does
not affect histamine metabolism, nor does it block histamine release in the body. Chlorpheniramine also has
central inhibition and anticholinergic effects, so after taking the drug, drowsiness, dry mouth, constipation,
sputum thickening and dry nasal mucosa.
Application of Chlorphenamine Maleate
After a long time of clinical practice that chlorpheniramine antihistamine
effect is strong, small dosage, small side effects. The antihistamine effect of chlorpheniramine was stronger than
that of diphenhydramine and promethazine, but the central inhibitory effect was weaker and the anticholine effect
was weaker. Due to drowsiness and other adverse reactions, it is suitable for children and patients who need to
work during the day. Chlorpheniramine can also reduce tracheal secretion and gastric acid secretion. Before the
new generation of antihistamines, is the most commonly used clinical antihistamines.
