Problems solved by technology

In the former method, the orally disintegrating tablets prepared are unevenly mixed with the three coating particles, resulting in unqualified quality and poor uniformity, which affect product quality and therapeutic effect. At the same time, the production process is complicated because the three active substances are coated separately , long working hours and high cost are not conducive to industrial production. The latter adopts dry mixing, which will also bring about the problem of uneven mixing, affecting product quality and curative effect
