POLYMYXIN B SULFATE AND TRIMETHOPRIM- POLYMYXIN B SULFATE AND TRIMETHOPRIM SULFATE SOLUTION/ DROPS BAUSCH & LOMB INCORPORATED ---------- POLYMYXIN B SULFATE ANDTRIMETHOPRIM OPHTHALMIC SOLUTION, USP (STERILE) RX ONLY FOR TOPICAL APPLICATION IN THE EYE DESCRIPTION Polymyxin B sulfate and trimethoprim ophthalmic solution, USP is a sterile antimicrobial solution for topical ophthalmic use. It has pH of 4.0 to 5.5 and osmolality of 270 to 310 mOsm/kg. CHEMICAL NAMES: Trimethoprim sulfate, 2,4-diamino-5-(3,4,5-trimethoxybenzyl) pyrimidine sulfate, is a white, odorless, crystalline powder with a molecular weight of 678.72 and the following structural formula: C H N O S Mol. Wt. 678.72 Polymyxin B sulfate is the sulfate salt of polymyxin B and B which are produced by the growth of _Bacillus polymyxa_ (Prazmowski) Migula (Fam. Bacillaceae). It has a potency of not less than 6,000 polymyxin B units per mg, calculated on an anhydrous basis. The structural formula is: 28 38 8 10 1 2 EACH ML CONTAINS: Actives: polymyxin B sulfate equal to 10,000 polymyxin B units, trimethoprim sulfate (equivalent to trimethoprim 1 mg); Inactives: purified water, sodium chloride. Sulfuric acid and, if necessary, sodium hydroxide may be added to adjust pH (4.0 – 5.5). Preservative: benzalkonium chloride 0.004% CLINICAL PHARMACOLOGY Trimethoprim is a synthetic antibacterial drug active against a wide variety of aerobic gram-positive and gram-negative ophthalmic pathogens. Trimethoprim blocks the production of tetrahydrofolic acid from dihydrofolic acid by binding to and reversibly inhibiting the enzyme dihydrofolate reductase. This binding is stronger for the bacterial enzyme than for the corresponding mammalian enzyme and therefore selectively interferes with bacterial biosynthesis of nucleic acids and proteins. Polymyxin B, a cyclic lipopeptide antibiotic, is bactericidal for a variety of gram-negative organisms, especially _Pseudomonas aeruginosa._ It increases the permeability of the bacterial cell membrane by interacting with the phosphol Izlasiet visu dokumentu
