    Abstract:
    The purpose of the present study was to compare the effectiveness of pirenzepine and carbenoxolone in accelerating the healing of chronic gastric ulcer. Sixty-six out-patients with endoscopically proven gastric ulcer, without major systemic diseases, were admitted to the study. Patients were randomly allocated to either pirenzepine, 50 mg three times a day for 6 weeks, or carbenoxolone, 100 mg three times a day for one week followed by 50 mg three times a day for the remaining five weeks. At 6 weeks, the ulcers had healed in 20 out of 34 patients (59%) treated with pirenzepine, and in 15 out of 29 patients (52%) treated with carbenoxolone. Symptomatic improvement was similar with both drugs. Some major side effects (oedema, hypokalaemia and hypertension) occurred in approximately 30% of patients treated with carbenoxolone; of those receiving pirenzepine 25% complained of minor symptoms (e.g. dry mouth, headache, tachycardia). It is concluded that pirenzepine and carbenoxolone are of similar, but rather limited, efficacy in speeding the healing of chronic gastric ulcer, but show important differences with respect to tolerability.
