Flucloxacillin, a new isoxazole penicillin, is active against penicillinase-producing strains of Staphylococcus aureus and is well absorbed in man after oral and intramuscular administration. Compared with isoxazole penicillins in current clinical use-namely, oxacillin, cloxacillin, and dicloxacillin-flucloxacillin has proved as active against Gram-positive cocci, including penicillin-resistant staphylococci. The extent of binding of flucloxacillin to the protein of human serum was similar to that of oxacillin and cloxacillin and less than that of dicloxacillin. In man flucloxacillin given orally produced total and free serum levels higher than those obtained with oxacillin and cloxacillin; total serum levels similar to those of dicloxacillin, and free levels greater than those of dicloxacillin. Similarly, after intramuscular injection the free serum levels of flucloxacillin were higher than those of oxacillin, cloxacillin, and dicloxacillin.
氟氯西林是一种新型异恶唑青霉素,对产青霉素酶的金黄色葡萄球菌菌株有活性,口服和肌内注射后在人体内吸收良好。与目前临床使用的异恶唑青霉素(即苯唑西林、氯唑西林和双氯西林)相比,氟氯西林已被证明对革兰氏阳性球菌(包括耐青霉素葡萄球菌)具有同等活性。氟氯西林与人血清蛋白的结合程度与苯唑西林和氯唑西林相似,低于双氯西林。在人体内,口服氟氯西林产生的总血清水平和游离血清水平高于苯唑西林和氯唑西林;总血清水平与双氯西林相似,游离水平高于双氯西林。同样,肌内注射后,氟氯西林的游离血清水平高于苯唑西林、氯唑西林和双氯西林。
