包装与药物的保管有着密切的关系。如片剂在包装不严密的情况下,会吸潮膨胀、松散或软化液化,有很多药物与空气长期接触,被水分与氧气的作用以致变色、分解,如毛地黄、青霉素、磺胺噻唑,重碳酸钠等。一些生药制片剂由于其中有一些霉菌,这些霉菌大都为需氧菌,在没有氧气和水分的供给下不能发育,若包装不严便大量得到氧和水分而使其发育致片剂生霉。复方阿司匹灵或阿司匹灵片因用易于吸潮的淀粉作赋形剂,由于包装不严致吸潮而逐渐分解析出水杨酸及醋酸:
Packaging and drug custody are closely related. Such as tablets in the case of packaging is not tight, will absorb moisture expansion, loose or softened liquefaction, many drugs and long-term exposure to the air, the role of moisture and oxygen discoloration, decomposition, such as fumonie, penicillin, sulfathiazole, Sodium carbonate and so on. Because of some molds, these molds are mostly aerobic bacteria that can not develop without the supply of oxygen and water. If the packaging is not strict, they will get a lot of oxygen and water to develop tablets mold mold. Compound aspirin or aspirin tablets due to the use of easy to absorb moisture as the excipient of starch, due to the packaging is not strict moisture absorption and gradually decomposed salicylic acid and acetic acid:
