The best time to take the drug needs specific analysis. The advantage of taking the drug before meals is that it can reduce the influence of food on drug absorption, improve the bioavailability of the drug, and allow the drug to work better. For a small number of patients who experience digestive system adverse reactions, such as nausea and vomiting, after taking the drug, as well as patients who usually have weak spleen and stomach functions, it would be more beneficial to health to take it after meals after weighing the pros and cons. Therefore, you can choose the right time to take the medicine according to your actual situation. It should be noted that once the time of taking the medication is determined, the medication should be taken at a basically fixed time throughout the period of taking the medication in order to maintain a stable blood concentration.
