The function of sustained-release agent is to delay the process of drug release, absorption, distribution, metabolism and excretion in vivo, so as to prolong the drug action time. General preparations are usually given once a day, and sustained-release preparations are only given once or twice a day, and the side effects are less than general preparations.

It is suggested that sustained-release drugs should not be taken apart because there is a controlled-release membrane outside the tablets, through which the drugs in the tablets are slowly released and maintain the effective blood concentration. If the drug is taken apart and the controlled-release film is destroyed, the stable release procedure of the tablet will be destroyed, which will lead to excessive drug release and fail to achieve the expected purpose.
