Nicorandil-Induced Hyperkalemia in a Uremic Patient
Nicorandil is an antianginal agent with nitrate-like and ATP-sensitive potassium channel activator properties.After activation of potassium channels, potassium ions are expelled out of the cells, which lead to membrane hyperpolarization, closure of voltage-gated calcium channels, and finally here vasodilation.We present a uremic case suffering from
