临床上,当抗生素需肠道外途径给药时,即使肌肉注射价廉且省时,但人们往往仍倾向于静脉内给药。这个问题很值得讨论。当然有些抗微生物和抗病毒药是不宜肌肉注射的。例如:万古霉素、灭滴灵、二性霉素B、阿糖腺苷因难以溶解,羧苄青霉素和羧噻吩青霉素因剂量太大均不适宜肌肉注射。通常使用的抗生素如:青霉素、氨基糖甙类,氯洁霉素、红霉 Clinically, when antibiotics are administered parenterally, even though intramuscular injection is inexpensive and time-saving, people tend to prefer intravenous administration. This question is worth discussing. Of course, some anti-microbial and antiviral drugs should not be intramuscularly injected. For example: vancomycin, metronidazole, amphotericin B, arabinoside due to difficult to dissolve, carbenicillin and cefpilor for large doses are not suitable for intramuscular injection. Commonly used antibiotics such as: penicillin, aminoglycosides, clindamycin, erythromycin
