[臨床藥學] 熱病修改Amikacin使用於透析病人劑量建議 (Dosing Recoemmendation of Amikacin in Patients Receiving Hemodialysis in the Sanford Guide)...

熱病 (the Sanford Guide) 一直是居家常備良藥,相信只要是醫師藥師,家裡多多少少會有這本"小本的",對藥師來說,"腎功能劑量劑量調整 (renal impairment adjustment)"這一塊,更是最常翻到爛的地方...

如果您手上有熱病,不論是2012~2013的,請看203頁,有關Aminoglycosides類抗生素使用於腎功能不全劑量調整...

For hemodialysis, CAPD

Amikacin HEMO: 15 mg/kg AD 3x/wk
Amikacin CAPD: 15-20 mg lost per L dialysate per day

在熱病非常有限的篇幅裡面,不知道每個人對上面這些語句的解讀是? 對接受血液透析病人來說,amikacin到底該如何投與?

事實上,我們就曾接獲醫師因為熱病建議開出非常高的劑量,監測血中濃度後當然是爆表到一個極致

經我們寫信給熱病的作者後,作者回信表示將會修改劑量建議,不讓他的"美意"被誤會了,來函原文照登:

Thank you for your inquiry. You are correct as to the confusing dose adjustment recommendation. In recognition , we adjusted the recommendation in the 2013  Print Guide; However, even there, we can do better.

The current recommendation as will be stated soon in the electronic version of the  Sanford Guide will read for patients on hemodialysis:

“In addition to the 7.5 mg/kg q48h dose, give an extra 50% (3.7 mg/kg) dose after dialysis. If the q48h dose is due on a dialysis day, give the 7.5 mg/kg dose before dialysis and the then the extra 3.7 mg/kg dose after dialysis.
Periodically check peak and trough serum levels. “

We have made similar adjustments to the recommendations for gentamicin and tobramycin.

Thank you for your interest in the Guide.  Dave Gilbert

我們對熱病中amikacin使用於血液透析病人的劑量建議存疑,作者回覆,將會改成

7.5 mg/kg Q48H,然後...

(1) 透析當天不給藥: 透析後補充一半劑量 (3.75 mg/kg)

(2) 透析當天給藥: 透析前給一完整劑量 (7.5 mg/kg),透析後再給一半劑量 (3.75 mg/kg)

我們很好奇,這樣有一點複雜的治療方法,臨床上的可行性如何,但就目前看來,很快地熱病上就會改用這種給藥方法...

事實上,文獻中越來越多討論傾向"透析前 (pre-dialysis)"給藥,而非傳統的"透析後 (post-dialysis)"給藥,好處是比起傳統的方法,更可以達到一定的波峰 (peak) 濃度,將再與熱病的作者討論相關的議題...[扶眼鏡,繼續看下去]
