pyrazinamid

A pyrazine that is used therapeutically as an antitubercular agent.
MSH

antibacterial derived from nicotinic acid, used as a tuberculostatic.
CSP

A synthetic pyrazinoic acid amide derivative with bactericidal property. Pyrazinamide is particularly active against slowly multiplying intracellular bacilli (unaffected by other drugs) by an unknown mechanism of action. Its bactericidal action is dependent upon the presence of bacterial pyrazinamidase, which removes the amide group to produce active pyrazinoic acid. Pyrazinamide is an important component of multidrug therapy for tuberculosis. (NCI04)

pyridostigminbromid

A cholinesterase inhibitor with a slightly longer duration of action than NEOSTIGMINE. It is used in the treatment of myasthenia gravis and to reverse the actions of muscle relaxants.
MSH

The bromide salt form of pyridostigmine, a quaternary ammonium carbamate derivative and a acetylcholinesterase inhibitor. Pyridostigmine bromide binds reversibly to acetylcholinesterase active sites in the peripheral nervous system, thereby preventing the breakdown of acetylcholine. This leads to an accumulation of acetylcholine at cholinergic synapses and facilitates transmission of impulses across the neuromuscular junction. Mediated through muscarinic receptors, this agent increases contraction of bronchial and intestinal smooth muscle and the exocrine glands secretions, while it causes paralysis of the skeletal muscles mediated through nicotinic receptors . In addition, pyridostigmine is used as a reversible blocking agent to prevent organophosphates from binding to the acetylcholinesterase receptors and thereby protect the nervous system from the effects of nerve agents such as Soman.
