[0002] Anorectal administration, also known as rectal administration, is a common way of drug administration. Its purpose is to deliver the drug directly into the colon and rectum, thereby avoiding the destruction of the drug in the stomach and reducing the occurrence of adverse gastrointestinal reactions. In addition, the drug can also enter the blood circulation directly through the rectal wall, thereby improving the bioavailability of the drug and making the drug work faster. Rectal administration can also be used for the treatment of some special drugs, such as drugs for treating constipation, which can be delivered directly into the rectum to promote defecation. In addition, rectal administration can also be used to treat some diseases, such as hemorrhoids, proctitis, etc. The drug can act directly on the lesion site and relieve symptoms. Rectal administration is an effective way of drug administration, which can improve the bioavailability and therapeutic effect of the drug and reduce the occurrence of adverse drug reactions. For example, anorectal administration can promote intestinal peristalsis, help defecation, and relieve constipation symptoms when constipated.
