咳嗽有黄色脓痰,家庭医生开的消炎药。biaxin XL 500mg clarithromycin 500mg
我怀疑是医生字迹潦草,抓药的PHARMACY弄错了。大家感觉呢?
google 了下,http://www.drugs.com/ppa/clarithromycin.html
Adults
PO Two 500 mg ER tablets every 24 h for 7 days.
PO是什么意思啊?
Elimination
The half-life is about 3 to 4 h (250 mg) and 5 to 7 h (500 mg). 20% to 40%
is excreted in urine as unchanged drug; 10% to 15% is excreted as 14-OH
clarithromycin. |

Biaxin XL,XL=extended release, so it last 24 hours compare to regular format.
So 2tabs once daily is reasonable. |

c********e 发帖数: 496 | 4 clarithromycin 两种给药方式都可以的,500mg Bid,或者 1000mg QD,没有区别的,
(很多其他的药是有区别的),每日服一次能增加患者服药的依从性。
药物一般在3-5个半衰期之后在体内清除,
P.O.是拉丁文,一种半象形文字, P就是pill,O就是张开的嘴, |
