Long-term therapy with carbenoxolone in the prevention of recurrence of gastric ulcer. Natural history and evolution of important side-effects and measures to avoid them.

Abstract

Between 1970 and 1979, 140 patients aged between 19 and 84 years with endoscopically confirmed gastric ulcer (GU), were treated with Biogastrone in reducing doses for 6 months. They received a daily dose of 300 mg for one week, 150 mg for 5 weeks, 100 mg for 6 weeks and 50 mg for the remainder of the 6 months. All the patients were reviewed at 2, 4, 6, 8, 12, 16, 20, 32, and 38 weeks and thereafter every 3 months or earlier in the event of significant dyspepsia. The anticipated recurrence rate of GU of approximately 42% at 2 years (3) was nearly halved to 26.7% over a median follow-up of 36 months in 140 cases completing the full six months course of treatment. The incidence of side effects was as follows: (i) A weight gain of 3.5 kg or more was seen in 23% of the patients at 2 weeks; this effect was maintained through the 6 month period. (ii) Oedema was noted in 14% of the patients at 2 weeks but declined to a 2% incidence by the end of the study. (iii) Elevated diastolic blood pressure in 14--18% of patients below 60 years and 20--27% patients above 60 years of age was noted throughout the study period. A high proportion of patients (38%) receiving other therapy had hypertension prior to the trial period; Carbenoxolone treatment had little further effect on blood pressure in these patients. (iv) Hypokalaemia was noted in the early stages of treatment especially in those over 60 years (43%). The incidence declined with the reduction in dosage through the 6 month treatment period. All side effects were successfully treated by diuretics and potassium supplements.
