MeSH

Salts of hydrobromic acid, HBr, with the bromine atom in the 1- oxidation state. (From McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

Drugs used to prevent SEIZURES or reduce their severity.

Hydrobromic acid (HBr). A solution of hydrogen bromide gas in water.

Year introduced: 1994

Inorganic compounds that contain bromine as an integral part of the molecule.

Year introduced: 1994

An atom or group of atoms that have a positive or negative electric charge due to a gain (negative charge) or loss (positive charge) of one or more electrons. Atoms with a positive charge are known as CATIONS; those with a negative charge are ANIONS.

A broad class of substances encompassing all those that do not include carbon and its derivatives as their principal elements. However, carbides, carbonates, cyanides, cyanates, and carbon disulfide are included in this class.

Year introduced: 1998

Substances that dissociate into two or more ions, to some extent, in water. Solutions of electrolytes thus conduct an electric current and can be decomposed by it (ELECTROLYSIS). (Grant and Hackh's Chemical Dictionary, 5th ed)

Negatively charged atoms, radicals or groups of atoms which travel to the anode or positive pole during electrolysis.

Year introduced: 1974

Uses of chemicals which affect the course of conditions, diseases, syndromes or pathology to benefit the health of an individual.

Year introduced: 2004

A broad category of chemical actions and uses that result in the prevention, treatment, cure or diagnosis of disease. Included here are drugs and chemicals that act by altering normal body functions, such as the REPRODUCTIVE CONTROL AGENTS and ANESTHETICS. Effects of chemicals on the environment are also included.

Year introduced: 2004(1999)

A group of pharmacologic activities, effects on living systems and the environment, and modes of employment of drugs and chemicals. They are broken into actions, which describe their effects, and uses, which describe how they are employed.

Year introduced: 1999

A class of drugs producing both physiological and psychological effects through a variety of mechanisms. They can be divided into specific agents, e.g., affecting an identifiable molecular mechanism unique to target cells bearing receptors for that agent, and nonspecific agents, those producing effects on different target cells and acting by diverse molecular mechanisms. Those with nonspecific mechanisms are generally further classed according to whether they produce behavioral depression or stimulation. Those with specific mechanisms are classed by locus of action or specific therapeutic use. (From Gilman AG, et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p252)
