Abstract
Adsorption, metabolism and excretion (ADME) of cefuroxime axetil (CXM-AX) 500 mg given orally at 30 minutes after meals to male volunteers who had undergone gastrectomy was compared with that of healthy volunteers.
1. The transition of the drug's serum concentrations was observed as follows: Tmax was somewhat shorter and T 1/2 longer in the gastrectomized volunteer group than in the healthy volunteer group.
2. Total urinary recovery rates of cefuroxime (CXM) were not significantly different between the 2 groups, averaging 53.6% for the gastrectomized volunteer group and averaging 54.5% for the healthy volunteer group.
3. Total urinary recovery rates of CXM-Δ2 were not significantly different between the 2 groups either, averaging 1.7% for the gastrectomized volunteer group and 1.3% for the healthy volunteer group.
4. The above results suggest that ADME of CXM-AX in the gastrectomized volunteers is not fundamentally different from that of the healthy volunteers. The absorption, however, may be reduced when peristalsis of the intestinal tract is accelerated as a result of gastrectomy.
