Quinidine (Chinidin) Summary

Description: An optical isomer of quinine, extracted from the bark of the Cinchona 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 potential, and decreases automaticity. Quinidine also blocks muscarinic and alpha-adrenergic neurotransmission.

Also Known As: Chinidin; Quinidex; Quinora; Adaquin; Apo-Quinidine Show All >>
