| P5'N | Pyrimidine 5' nucleotidase |
|---|---|
| PD | Pyrimidine dimer |
| PyNPase | Pyrimidine nucleoside phosphorylase |
| antibiotics, antitubercular | Substances obtained from various species of microorganisms that are, alone or in combination with other agents, of use in treating various forms of tuberculosis; most of these agents are merely bacteriostatic, induce resistance in the organisms, and may be toxic. (12 Dec 1998) |
|---|---|
| antibiotics, combined | Combination of antibiotics used against difficult-to-treat infections. Antibiotic combinations have been used mainly to broaden the antibacterial spectrum and prevent development of resistance. In some instances these combinations have shown lower toxicity, but drug antagonism may be one of the problems encountered by their use. They may be given simultaneously or sequentially. The drugs need not be in the same dosage form. (12 Dec 1998) |
| antibiotics, glycopeptide | Antibiotics whose structure contains one or more cyclic peptides to which are attached one or more deoxy sugars in glycosidic linkage. They are generally effective against gram-positive bacteria and act by inhibiting peptidoglycan synthesis in bacterial cell walls. (12 Dec 1998) |
| antibiotics, lactam | Compounds containing a four-membered ring with an amide nitrogen and a keto group. This configuration includes bacteriostatic, cell-wall inhibiting antibiotics, such as penicillins and cephalosporins; their analogs and derivatives, such as the penem (or penam) compounds; clavulanic acids; and monobactams. They are substrates for and may act as inhibitors of bacterial beta-lactamases. (12 Dec 1998) |
| antibiotics, macrolide | A group of antibiotics containing a macrocyclic lactone ring linked glycosidically to one or more sugar moieties. These antibiotics are produced by certain species of streptomyces. They often inhibit protein synthesis by binding to the 50s subunits of 70s ribosomes. (12 Dec 1998) |
| antibiotics, peptide | Antibiotics whose structure contains one or more peptides, usually cyclic. They are generally effective against gram-positive bacteria and act by inhibiting peptidoglycan synthesis in bacterial cell walls. (12 Dec 1998) |
| antibiotics, tetracycline | <chemical> Broad-spectrum natural and semisynthetic antibiotics with a naphthacene structure obtained from various streptomyces species. Pharmacological action: protein synthesis inhibitor. (12 Dec 1998) |
| intravenous antibiotics | The administration of an antibiotic solution into the venous circulation. (27 Sep 1997) |
| topical antibiotics | A ointment (or cream) based medication that kills bacteria. Examples include Neosporin, Bactroban, Garamycin, bacitracin, gentamicin, mupirocin, neomycin, silver sulphasalazine, chloramphenicol and clindamycin. (27 Sep 1997) |
