Antiarrhythmic Agent
Antiarrhythmic agents, also known as cardiac dysrhythmia medications, are a class of drugs that are used to suppress abnormally fast rhythms (tachycardias), such as atrial fibrillation, supraventricular tachycardia and ventricular tachycardia. Many attempts have been made to classify antiarrhythmic agents. Many of the antiarrhythmic agents have multiple modes of action, which makes any classification imprecise. Action potential The cardiac myocyte has two general types of action potentials: conduction system and working myocardium. The action potential is divided into 5 phases and shown in the diagram. The sharp rise in voltage ("0") corresponds to the influx of sodium ions, whereas the two decays ("1" and "3", respectively) correspond to the sodium-channel inactivation and the repolarizing efflux of potassium ions. The characteristic plateau ("2") results from the opening of voltage-sensitive calcium channels. Each phase utilizes different channels and it is useful to compar ...

Carbamates
In organic chemistry, a carbamate is a category of organic compounds with the general formula and structure , which are formally derived from carbamic acid (). The term includes organic compounds (e.g., the ester ethyl carbamate), formally obtained by replacing one or more of the hydrogen atoms by other organic functional groups; as well as salts with the carbamate anion (e.g. ammonium carbamate). Polymers whose repeat units are joined by carbamate like groups are an important family of plastics, the polyurethanes. See for clarification. Properties While carbamic acids are unstable, many carbamate esters and salts are stable and well known. Equilibrium with carbonate and bicarbonate In water solutions, the carbamate anion slowly equilibrates with the ammonium cation and the carbonate or bicarbonate anions: : : Calcium carbamate is soluble in water, whereas calcium carbonate is not. Adding a calcium salt to an ammonium carbamate/carbonate solution will precipitate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dibenzazepines
Dibenzazepine (iminostilbene) is a chemical compound with two benzene rings fused to an azepine ring. Many pharmaceuticals, such as carbamazepine, oxcarbazepine, and depramine, are based on a dibenzazepine structure. See also * Benzazepine * Dibenzothiazepine * Dibenzothiepin * Dibenzoxepin Dibenzoxepin, or dibenz 'b'',''e''xepin, is a tricyclic compound. It is the parent structure of certain drugs such as the tricyclic antidepressant doxepin and the analgesic fluradoline. The former is the only tricyclic antidepressant that is a di ... * Iminodibenzyl References External links * {{Chemical classes of psychoactive drugs Tricyclic antidepressants Aromatic amines Nitrogen heterocycles ...
