Novel use of famotidine in treatment of frozen shoulder: a case report

Famotidine is a H2 receptor blocker used to reduce gastric acid secretion. This case report highlights a novel use of famotidine. It may be used in the treatment of frozen shoulder. Frozen shoulder is a pathological condition characterised by restricted shoulder movement. We present a case report of a diabetic and hypertensive patient suffering from frozen shoulder along with hyperacidity and gastroesophageal reflux disease (GERD). Famotidine was prescribed for treatment of GERD. Famotidine not only provides relief from acidity but also results in decrease in pain score, disability score and shoulder pain and disability index (SPADI) due to frozen shoulder with improved movement. This therapeutic importance encourages us to report the significance of Famotidine in frozen shoulder. This also opens a new dimension in the role of acidity in the study of pathophysiology of frozen shoulder.
