Pharmacokinetics and tissue penetration of temocillin.
The pharmacokinetics of intravenous (bolus) temocillin 1 g were studied in 6 healthy male volunteers, and a cantharides blister method was used to estimate tissue penetration of the antibiotic. The mean elimination half-life was 4.5 hours. Temocillin penetrated blister fluid rapidly and reached concentrations of about 50% of those in serum by 2 to 3 hours after administration. Over an 8-hour period, the serum and blister fluid concentrations exceeded the MIC90 of susceptible bacteria by 2-fold or greater, suggesting that twice or even once daily dosing with temocillin may be sufficient.
