Preparation Process And Quality Standard Research Of Mida-naxin Pill

Imidafenacin is a new type of drugs, The Chemical structure is 4-(2-Methyl-1H-imidazol-1-yl)-2, 2-Dip Henylbutanamide of highly selective in bladder, It is usually used in the treatment of bladder excessive activity. Imidafenacin can inhibit bladder smooth muscle contraction and inhibition of acetylcholine free dual role, and the selectivity of bladder strong in the salivary glands. For brain tissue, the affinity of the receptors is low, and the central and peripheral adverse reactions are less, which can reduce the adverse reactions on the basis of the effect of the treatment. At present, there is no perfect preparation process and quality standard method in this standard, therefore, the preparation process and quality standard of this preparation is studied. Using high performance liquid chromatography to identification test, determination of content uniformity, dissolution test and detection method specificity test. It provides a basis for the preparation of the test method.
