抗藥性機轉¶
藥物動力學 (Pharmakokinetics)¶
- 描述藥物在體內的分布情況
Drugs binding to serum proteins have a major influence on V\(_d\) . Acidic drugs tend to bind to albumin and typically have lower V\(_d\) values because they are retained in the plasma compartment. Basic drugs tend to bind to α 1 -acid glycoprotein and are retained within tissues leading to larger V\(_d\) estimates. Protein binding is an important consideration for antimicrobial agents because unbound drug is available to exert antimicrobial activity, and in vitro methods used to assess potency through the MIC evaluate unbound drug.
Penetration/Tissue concentration¶
- 過BBB: penicillin, ampicillin, oxacillin, 3rd-4th cephalosporins, moxifloxacin, vancomycin, chloramphenicol, rifampin, imipenem, meropenem, trimethoprim-sulfamethoxazole
- Prostatitis/epididymo-orchitis: ceftriaxone, doxycycline, fluoroquinolones, trimethoprim-sulfamethoxazole
- Endophthalmitis: 3rd cepha, vancomycin, triazoles, L-AMB
- Intracellular bacteria: lipid soluble agents (e.g. macrolides, quinolones, rifampicin)
Bone penetration for selected antibiotics¶
Antibiotic | Range of mean bone to serum concentration ratios |
---|---|
Levofloxacin | 0.36-1.0 |
Ciprofloxacin | 0.27-1.2 |
Moxifloxacin | 0.33-1.05 |
Vancomycin | 0.05-0.67 |
Linezolid | 0.2-0.51 |
Daptomycin | 1.17 |
Clindamycin | 0.21-0.45 |
Cefazolin | 0.179 |
Ceftriaxone | 0.07-0.17 |
Cefuroxime | 0.04-0.55 |
Rifampin (rifampicin) | 0.08-0.57 |
藥效動力學 (Pharmakodynamics)¶
- 描述藥物作用於病原體的決定因素,並與藥物動力學因素相關
濃度依賴型抗生素¶
這類抗生素多為抑制細菌蛋白質或核酸合成的抗生素,如aminoglycosides、fluoroquinolones,因其殺菌作用與血中濃度呈正比,為達最大之殺菌作用,建議抗生素之Cmax須高於MIC 4倍以上,且因其有抗生素後效應 (Post-antibiotic effect, PAE) 的特性,即便血中藥物濃度在給藥間隔期間內低於MIC,仍可維持一定的抗菌作用。因此採高劑量、延長給藥間隔的方式投予是比較理想的方式,once-daily aminoglycoside的給藥模式即以此理念所發展。
時間依賴型抗生素¶
這類抗生素多為beta-lactams類,如penicillin、cephalosporins。對penicillin和cephalosporins而言,血中藥物濃度>MIC的時間越長越能滲透體內組織,建議治療期間的血中濃度有50%以上的時間高於MIC,以達療效最大化、抗生素耐藥性最小化的目標。此類藥品以連續輸注或延長輸注時間的方式給藥,除了可穩定抗生素血中濃度的變化、不增加重症患者AKI的發生率外,對整體的醫療照護支出費用也可顯著降低。
曲線下面積/最低抑菌濃度相關¶
如vancomycin,建議血中藥物濃度之曲線下面積 (AUC) 與MIC比值達到400-600
mg × h/L的目標(假設MIC為1),可確保抗生素療效與安全性。

- 腸道菌群失衡(可能導致偽膜性腸炎)
- 血小板減少症
Ceftriaxone¶
- 肝毒性、黃疸
- 不可加入含鈣之點滴注射液
Cefepime¶
- 神經毒性(尤其是在腎功能受損的病人中,可能引起癲癇)
Carbapenems¶
- 神經毒性(特別是在高劑量或腎功能不全時)
Aminoglycosides (Gentamicin)¶
- 腎毒性:preexisting renal impairment, concomitant nephrotoxic medications, advanced age and dehydration
- 耳毒性(可能引起聽力損失或平衡障礙):proportional to the amount of drug given and the duration of treatment; tinnitus or vertigo may be indications of vestibular injury and impending bilateral irreversible damage

- 高血鉀
- 腎毒性
- 肝毒性
- 過敏反應
- 骨髓抑制(可能引起貧血、白血球減少、血小板減少)
Vancomycin¶
- 腎毒性
- 耳毒性
- 嗜中性球低下、白血球減少、血小板減少
- Red man syndrome:與vancomycin的劑量有所關聯,特別是發生在劑量較大且快速滴注時。主要是由皮膚、肺、腸胃道、心肌及血管系統中的肥大細胞及嗜鹼性白血球釋出組織胺所導致的。此現象通常發生在首次的給予劑量,但也可能會發生在任何一個給藥時間。一般常見的典型的症狀為上半身軀幹有潮紅、紅疹、蕁麻疹及搔癢之現象,在幾個比較嚴重的案例中曾發現低血壓、胸痛及呼吸窘迫之症狀。
- 全身性過敏反應:是一種急性且危及生命的免疫反應,一般發生非常迅速,通常在給藥後之5-30分鐘以內發作。首先病人會對vancomycin敏感而在體內產生vancomycin特異性的IgE(vancomycin-specific IgE)。若對產生過敏之病人重複投予vancomycin會造成敏感性肥大細胞上的IgE接受器產生交叉連結反應,而引起血管活化調節物質的釋出,這些物質例如有組織胺、白三稀素C4(leukotriene C4)、前列腺素(prostaglandin D2)及細胞介質素,例如:腫瘤壞死因子(TNF-a)及interleukin 4, 5, 6, 7, 8及13。因為這些物質之釋出而擴大vancomycin之過敏反應進而產生血管擴張作用引起全身性皮膚紅疹、搔癢、蕁麻疹、支氣管收縮、腸道過度蠕動、低血壓或心律不整。
