NUROMAX™ Glaxo Wellcome Doxacurium Chloride Nondepolarizing Skeletal Neuromuscular Blocking Agent Action And Clinical Pharmacology: Doxacurium is a long-acting, nondepolarizing, skeletal neuromuscular blocking agent for i.v. administration. Nondepolarizing agents antagonize the neurotransmitter action of acetylcholine by binding competitively with cholinergic receptor sites on the motor end-plates. This antagonism is inhibited, and neuromuscular block reversed, by acetylcholinesterase inhibitors such as neostigmine. Pharmacodynamics: Doxacurium is approximately 2.5 to 3 times more potent than…

NOVO-VERAMIL SR Novopharm Verapamil HCl Antiarrhythmic – Antianginal – Antihypertensive Antihypertensive Action And Clinical Pharmacology: Angina and Arrhythmia: Verapamil, a calcium ion influx inhibitor (calcium entry blocker or calcium ion antagonist) is believed to exert its antiarrhythmic and antianginal effects by selectively inhibiting transmembrane influx of calcium ions in cardiac muscle, coronary and systemic arteries and in cells of the intracardiac conduction system. Verapamil blocks the transmembrane influx of calcium…

NOVOCAIN® Sanofi Procaine HCl Local Anesthetic Action And Clinical Pharmacology: Local anesthetics block the generation and the conduction of nerve impulses, presumably by increasing the threshold for electrical excitation in the nerve, by slowing the propagation of the nerve impulse and by reducing the rate of rise of the action potential. In general, the progression of anesthesia is related to the diameter, myelination, and conduction velocity of affected nerve fibres….
