antihypertensive agent |
bretylium
bretylium: RN given refers to parent cpd. bretylium : A quaternary ammonium cation having 2-bromobenzyl, ethyl and two methyl groups attached to the nitrogen. It blocks noradrenaline release from the peripheral sympathetic nervous system, and is used in emergency medicine, cardiology, and other specialties for the acute management of ventricular tachycardia and ventricular fibrillation. | 1.96 | 1 | 0 | quaternary ammonium ion | adrenergic antagonist;
anti-arrhythmia drug;
antihypertensive agent |
guanethidine
Guanethidine: An antihypertensive agent that acts by inhibiting selectively transmission in post-ganglionic adrenergic nerves. It is believed to act mainly by preventing the release of norepinephrine at nerve endings and causes depletion of norepinephrine in peripheral sympathetic nerve terminals as well as in tissues.. guanethidine : A member of the class of guanidines in which one of the hydrogens of the amino group has been replaced by a 2-azocan-1-ylethyl group.. guanethidine sulfate : A organic sulfate salt composed of two molecules of guanethidine and one of sulfuric acid. | 1.96 | 1 | 0 | azocanes;
guanidines | adrenergic antagonist;
antihypertensive agent;
sympatholytic agent |
lidocaine
Lidocaine: A local anesthetic and cardiac depressant used as an antiarrhythmia agent. Its actions are more intense and its effects more prolonged than those of PROCAINE but its duration of action is shorter than that of BUPIVACAINE or PRILOCAINE.. lidocaine : The monocarboxylic acid amide resulting from the formal condensation of N,N-diethylglycine with 2,6-dimethylaniline. | 1.96 | 1 | 0 | benzenes;

procainamide
Procainamide: A class Ia antiarrhythmic drug that is structurally-related to PROCAINE.. procainamide : A benzamide that is 4-aminobenzamide substituted on the amide N by a 2-(diethylamino)ethyl group. It is a pharmaceutical antiarrhythmic agent used for the medical treatment of cardiac arrhythmias. | 1.96 | 1 | 0 | benzamides | anti-arrhythmia drug;
platelet aggregation inhibitor;

ouabain
Ouabain: A cardioactive glycoside consisting of rhamnose and ouabagenin, obtained from the seeds of Strophanthus gratus and other plants of the Apocynaceae; used like DIGITALIS. It is commonly used in cell biological studies as an inhibitor of the NA(+)-K(+)-EXCHANGING ATPASE.. cardiac glycoside : Steroid lactones containing sugar residues that act on the contractile force of the cardiac muscles.. ouabain : A steroid hormone that is a multi-hydroxylated alpha-L-rhamnosyl cardenoloide. It binds to and inhibits the plasma membrane Na(+)/K(+)-ATPase (sodium pump). It has been isolated naturally from Strophanthus gratus. | 1.96 | 1 | 0 | 11alpha-hydroxy steroid;

quinidine
Quinidine: 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 : A cinchona alkaloid consisting of cinchonine with the hydrogen at the 6-position of the quinoline ring substituted by methoxy. | 6.96 | 1 | 0 | cinchona alkaloid | alpha-adrenergic antagonist;
