Evaluation of H2 receptor antagonists in chronic idiopathic urticaria.
H1-antagonist (hydroxyzine hydrochloride) in dosage of 10 mg-25 mg thrice a day failed to elicit satisfactory response in 60 out of 170 patients of chronic idiopathic urticaria. Additional administration of H2-antagonist (cimetidine) in dosage of 200 mg four times a day, in patients not responding earlier to H1-antagonist alones exhibited moderate to good improvement of various parameters of urticaria in approximately 85% patients.
