Synopen

Synopen Uses, Dosage, Side Effects, Food Interaction and all others data.

Chlorpyramine is a first generation antihistamine used in Eastern European countries to treat bronchial asthma as well as allergice rhinitis, allergic conjunctivitis, and other allergic reactions. It is also indicated for Quincke's edema, allergic reactions to insect bites, food and drug allergies, and anaphylactic shock.

Chlorpyramine is a competitive reversible H1 receptor antagonist. This inhibits vasodilation, increases in vascular permeability, and tissue edema associated with histamine release. In addition, chloropyramine has some anticholinergic properties. These effects, along with its ability to pass through the blood-brain barrier lead to side effects such as drowsiness, weakness, vertigo, fatigue, dryness in the mouth, constipation, and rarely - visual disturbances and increase of intraocular pressure.

How Synopen works

Synopen binds to the histamine H1 receptor. This blocks the action of endogenous histamine, which subsequently leads to temporary relief of the negative symptoms brought on by histamine.
