DESCRIPTION Gentamicin Sulfate is a water-soluble antibiotic of the aminoglycoside group. Gentamicin Sulfate Ophthalmic Solution is a sterile, aqueous solution buffered to approximately pH 7 for ophthalmic use. Gentamicin is obtained from cultures of Micromonospora purpurea . It is a mixture of the sulfate salts of gentamicin C 1 , C 2 , and C 1A . All three components appear to have similar antimicrobial activities. Gentamicin sulfate occurs as white powder and is soluble in water and insoluble in alcohol. The structure is as follows: Established name: Gentamicin Sulfate Chemical name: 0-3-Deoxy-4-C-methyl-3-(methylamino)-β-L-arabinopyranosyl-(1→6)-0-[2,6-diamino-2,3,4,6-tetradeoxy-α-D-erythro-hexopyranosyl-(1→4)]-2-deoxy-D-streptamine. Ingredients: Each mL contains: Active: Gentamicin Sulfate USP (equivalent to 3 mg gentamicin). Preservative: Benzalkonium Chloride 0.1 mg (0.01%). Inactives: Dibasic Sodium Phosphate Anhydrous, Sodium Chloride, Sodium Hydroxide and/or Hydrochloric Acid (to adjust pH), Tyloxapol and Purified Water. chemicalstructure
