“大病进医院,小病进药店”已经成为人们治病的习惯,可目前常用治病药物中,尽管每一种药物各有所长,但作用多是大同小异,有时可以互相代替。人生病之后,不但希望能早日康复,而且希望能尽量少花钱,这就需要科学、经济地选用药物。 “Ill into the hospital, a small illness into the pharmacy ” has become the habit of people to cure, but currently used in the treatment of drugs, although each drug has its own strengths, but the role is more or less the same, and sometimes can replace each other. After people get sick, they not only hope to recover soon, but also hope to spend as little as possible. This requires the scientific and economical selection of drugs.
