Chlorpheniramine-d6 is intended for use as an internal standard for the quantification of chlorpheniramine (Item No. 21253) by GC- or LC-MS. Chlorpheniramine is a histamine H1 receptor antagonist with an IC75 value of 0.0016 ?g/ml for reversal of histamine-induced spasms in isolated guinea pig ileum.{39804} It protects against intravenous histamine-induced death (PD50 = 0.15 mg/kg) and delays induction of aerosolized histamine-induced coughing (ED100sec = 0.44 mg/kg) in guinea pigs. Chlorpheniramine (20 mg/kg, i.p.) prevents histamine-induced passive cutaneous anaphylaxis (PCA) in rabbits.{39805} It also reduces respiratory resistance and hypersecretion of tracheobronchial fluid in a dog model of histamine-induced asthma.{39806} Formulations containing chlorpheniramine have been used in the treatment of seasonal allergies.
