Kinetics of cefatrizine penetration into gynaecological tissues after oral administration.

Twenty-four patients, hospitalized in order to undergo radical gynaecological surgery, were orally administered cefatrizine in a single dose of 1 g at different times before surgery. The tissue levels determined in the organs considered (uterus, ovary, tubae, vagina) proved that cefatrizine possesses good absorption in the genital tract, reaching concentrations near to the MICs of most gram-negative and gram-positive sensitive bacteria lasting even 12 h after administration.
