Both drugs are nifedipine extended-release tablets in the same dosage, but we use sodium alginate slow-controlled technology for our drug, while Xingueda uses skeletal extended-release technology. The difference between the two technologies is the duration of efficacy, which is 12-16 hours for Nifuda and 8-12 hours for Skeletal Sustained Release. Ourfada is indicated for patients with hypertension, severe hypertension, and respiratory disease with good efficacy and relatively few side effects, while Xingueda is also used to treat hypertension and variant angina pectoris. Both drugs have the same adverse reactions, essentially the same, but with technical differences. And the doses taken are basically the same, mainly because the instructions are different and the manufacturers are different. Both can treat various types of hypertension, angina pectoris and other diseases, and should be taken in accordance with the instructions to differentiate.
