Hypoglycaemic coma due to chlorpropamide: observations on twenty-two patients

Area of Science:

• Geriatric Medicine
• Pharmacology
• Endocrinology

Background:

• Chlorpropamide is an oral hypoglycaemic agent used for type 2 diabetes.
• Elderly populations are susceptible to adverse drug reactions.
• Hypoglycaemia can lead to severe morbidity and mortality.

Observation:

• A medical center observed 22 cases of chlorpropamide-induced hypoglycaemic coma.
• The median patient age was 72, with many over 80.
• Four patients died, three potentially due to hypoglycaemia.

Findings:

• Contraindications for chlorpropamide use were present in most patients, irrespective of age.
• Hypoglycaemia occurred postoperatively in two patients.
• Nineteen of 22 cases might have been preventable with stricter prescribing practices and age considerations.

Implications:

• Reinforces the need for careful patient selection and monitoring when prescribing chlorpropamide.
• Highlights the importance of considering advanced age as a relative contraindication.
• Suggests improved adherence to prescribing guidelines could reduce adverse events in geriatric patients.
