Pathway Description
Aceprometazine H1 Antihistamine Smooth Muscle Relaxation Action Pathway
Homo sapiens
Drug Action Pathway
Aceprometazine is a is a drug with neuroleptic and anti-histamine properties. Although not widely prescribed, it is used in combination with meprobamate for the treatment of sleep disorders in France under the trade name Mepronizine. Aceprometazine, acting as an H1-receptor antagonist can induce sedation by being able to cross the blood-brain-barrier and binding to H1-receptors in the central nervous system.
H1-antihistamines interfere with the agonist action of histamine at the H1 receptor and are administered to attenuate inflammatory process in order to treat conditions such as allergic rhinitis, allergic conjunctivitis, and urticaria. H1-antihistamines act on H1 receptors in T-cells to inhibit the immune response, in blood vessels to constrict dilated blood vessels, and in smooth muscles of lungs and intestines to relax those muscles. Allergies causes blood vessel dilation which causes swelling (edema) and fluid leakage.
