Amlodipine gynaecomastia

We report only the second published confirmed case of gynaecomastia caused by amlodipine (a dihydropyridine calcium channel blocker). Gynaecomastia developed in a 70-year-old male within 3 months of starting amlodipine, and symptoms resolved within 3 weeks of drug withdrawal suggesting a strong relationship between amlodipine and gynaecomastia in this patient. Recent research has suggested possible interesting novel mechanisms for amlodipine gynaecomastia, which are discussed.
