Introduction: Nicorandil is a potassium channel activator used for the treatment for refractory angina. GIT ulceration associated with Nicorandil is well reported , however to our knowledge this is the first case report of Nicorandil causing FSGS and Bullous pemphigoid.
Case report: 81 year old female presented with bullous skin lesions and nephrotic syndrome. Nicorandil was commenced for refractory angina 6 months ago and it had been stopped due to blistering skin lesions. Due to ongoing angina, Nicorandil was recommenced approximately 4 weeks prior to current presentation. Bullous lesions reappeared followed by onset of leg oedema and swelling. She underwent a renal and skin biopsy which showed Focal segmental glomerulosclerosis and bullous pemphigoid respectively. Nicorandil was discontinued and prednisone 40mg was commenced. The nephrotic syndrome remitted within one week and the skin lesions have completely healed with no further new lesions.
Conclusion: Nicorandil has been increasingly used for the management of refractory angina. In our case, it was associated with causing cutaneous lesions and glomerular injury which completely remitted after stopping the drug. Awareness of possibility of this condition is crucial for prescribers.
