An optical isomer of quinine, extracted from the bark of the CHINCHONA tree and similar plant species. This alkaloid dampens the excitability of cardiac and skeletal muscles by blocking sodium and potassium currents across cellular membranes. It prolongs cellular ACTION POTENTIALS, and decreases automaticity. Quinidine also blocks muscarinic and alpha-adrenergic neurotransmission.
Quinidine has been studied across 11 research domains including ❤️ Cardiovascular, 🧠 Focus & Attention, 🫁 Liver & Detox, ⚡ Energy & Fatigue, 🫘 Kidney. The primary research focus is ❤️ Cardiovascular with 33% of studies addressing this area.
