Descripción

Application

Quinidine has been used:

• as an inhibitor of cytochrome P450 enzyme isoform CYP2D6
• as a potassium (K⁺) channel blocker in microglia
• to test its effect on electrophysiological behaviour of human induced pluripotent stem cells (hiPSC) cardiomyocytes

Biochem/physiol Actions

Quinidine, an isomer of quinine has potential side effects like proarrhythmia on usage. It prolongs cardiac potential and is sodium channel blocker. It is a potential antagonist for α1-adrenoceptors and contributes to hypotension. It inhibits cytochrome P450 2D6 and improves circulation and brain penetration of dementia drug, dextromethorphan. Quinidine-dextromethorphan combination may be useful in treating pseudobulbar affect (PBA).

Class IA antiarrhythmic; potassium channel blocker.
