TEMAFLOXACIN HYDROCHLORIDE

Description

Temafloxacin hydrochloride is a new fluoroquinolone antibacterial structurally and mechanistically related to tosufloxacin, another microbial DNA topoisomerase inhibitor introduced in 1990. It is particularly useful against beta-lactamase producing organisms and is indicated for the treatment of respiratory and urinary tract infections as well as sexually transmitted diseases, skin and soft tissue infections. The compound has high tissue penetration and is reported to have a low propensity to cause adverse effects and drug interactions.

Originator

Abbott (U.S.A.)

Uses

Temafloxacin Hydrochloride is an antimicrobial quinolone drug.

Uses

Antibacterial (microbial DNA topoisomerase inhibitor).

brand name

Omniflox (Abbott);Temac.

in vitro

the in-vitro activities of temafloxacin, ciprofloxacin, and ofloxacin against gram-negative bacteria were compared. the 90% minimal inhibitory concentrations (mic90s) of temafloxacin for respiratory pathogens were less than or equal to 0.06 micrograms/ml. temafloxacin was also active against bacterial agents of sexually transmitted diseases, such as neisseria gonorrhoeae and chlamydia trachomatis [1].

in vivo

mixed aerobic-anaerobic infection was induced by i.p. implantation of gelatin capsules containing bacteroides fragilis, escherichia coli, and sterile rat faeces. temafloxacin was found to be highly active with a 90.9% cure rate in comparison with no treatment, and as active as a combination of clindamycin and gentamicin. temafloxacin at 12 mg/dose resulted in rise to serum concentrations exceeding the mic values of both microorganisms for at least 8 h [2].
