Pulmorest D helps in the treatment of chronic cough due to allergic rhinitis by reducing allergy related symptoms and suppressing coughing. Please contact your physician for dosages.
Chlorpheniramine in Pulmorest D is a first generation H1 receptor blocker. It competitively antagonizes action of histamine at H1 receptors. The effectively blocked histamine induces bronchoconstriction and many manifestations of immediate hypersensitivity (Type -1).
