As for the effect, many papers were published in the national core medical journals to compare the efficacy and side effects of domestic and imported nifedipine sustained-release tablets, and the conclusions are consistent: domestic nifedipine controlled-release tablets and imported nifedipine controlled-release tablets are effective and safe in treating essential hypertension, with few adverse reactions and good tolerance, and are satisfactory antihypertensive drugs for patients with mild to moderate hypertension. There is no significant difference in statistical data.
Clinically, for patients with good economic conditions, new drugs are generally prescribed, while for patients with poor economic conditions, domestic nifedipine sustained-release tablets are used. It's actually just a sales tool. Specific to the antihypertensive effect and side effects, there is really no difference.
Analyze the specific situation and choose the medicine that suits you according to your own conditions.
