Identification
- Summary
Dexchlorpheniramine is a chlorpheniramine enantiomer antihistamine indicated in the treatment of sunburns, insect bites, and allergic reactions of the skin.
- Generic Name
- Dexchlorpheniramine
- DrugBank Accession Number
- DB13679
- Background
Dexchlorpheniramine is a potent S-enantiomer of chlorpheniramine. The salt form dexchlorpheniramine maleate as the active ingredient is available as a prescription drug indicated for adjunctive therapy for allergic and anaphylactic reactions. It is an antihistamine drug with anticholinergic (drying) and sedative actions. It disrupts histamine signaling by competing with histamine for cell receptor sites on effector cells.
