消化不良时,很多人会选择胃动力药,但这类药并不是随时难受了就能吃,最好在饭前服用。胃动力药是能增强胃蠕动、加速胃排空的药物,能改善胃胀、呕吐、恶心等症状,常见的有多潘立酮(吗丁啉)、西沙比利、甲氧氯普胺(胃复安)等。有人认为,胃动力药应该在饭后服用,能给消化“加把劲”。可事实恰恰相反,在饭前空腹时,胃动力药更容易被吸收。以吗丁啉为例,服药后分钟,其血药浓度达到高峰。如果在餐前分钟左右服药,进餐时正值血药浓度达高峰时,也正是药效最强的时候。相反,如果饭后吃,不仅吸收差、药效发挥晚,有些人还会饿得更快,再吃东西后胃胀更严重。
Indigestion, many people will choose gastric motility drug, but these drugs are not always uncomfortable to eat, it is best to take before meals. Gastric drug is to enhance gastric motility, gastric emptying to speed up the drug, can improve the bloating, vomiting, nausea and other symptoms, the common domperidone (domperidone), cisapride, metoclopramide )Wait. Some people think that gastric motility drugs should be taken after a meal, to give digestion, “plus”. But the fact is the opposite, when fasting before meals, gastric motive drugs are more easily absorbed. To domperidone, for example, after taking the minute, the plasma concentration reached its peak. If you take medication about minutes before a meal, when the meal is at a peak blood concentration, it is also the most effective time. On the contrary, if you eat after a meal, not only will it be poorly absorbed, but the efficacy will be late, and some people will starve more quickly.
