Stabilization compositions for cysteamine and its hydrochloride and process method related. The composition comprises the following ingredients on the basis of percent by weight: A, 10~60% of cysteamine and its hydrochloride; B, 1~15% of molecular sieve; C, 1~50% of skeleton material; D, 10~80% of diluent. The method comprises: adsorbing cysteamine and its hydrochloride into molecular sieve selecting from zeolite and silica gel, and adding skeleton material and diluent, to obtain skeleton slow-released granule preparation with high stability. |
