Description

Technical Field

[0002] When producing drugs, pharmaceutical companies will choose to make the drugs into corresponding tablets, capsules, powders, etc. according to the conventional usage of the drugs, so as to facilitate patients to take them. In hospital departments, doctors will formulate corresponding medication plans according to the specific symptoms of patients. This will make the patient's medication method inconsistent with the customary finished state of the drugs in some specific cases; for example, when acute symptoms occur in the anorectal department, when direct oral medication can stabilize the symptoms, and conventional symptomatic drugs are in the form of tablets, if tablets are taken directly, the tablets will break down slowly after taking them, making the drug effect slower and the effect on acute symptoms poor.
