Background
The ointment is a uniform semisolid external preparation prepared by mixing the raw material medicines with an oleaginous or water-soluble matrix. Suppositories are solid preparations of the drug with a suitable matrix having a shape for administration in the human body lumen. The suppository is solid at normal temperature, and can be rapidly softened and melted or dissolved in secretion at body temperature after being plugged into the cavity, and gradually releases the medicine to produce local or systemic effect.
The ointment is a commonly used pharmaceutical dosage form for anorectal diseases, and when in use, the ointment is usually connected to an ointment opening through a disposable plastic tube, the front end of the plastic tube is implanted into the anus, and the medicine is led into the anorectum through extrusion. However, this method has a certain disadvantage, in which the most important is that the medicine remains in the disposable plastic tube, and the disposable plastic tube needs to be replaced every time it is used, and each time it is used, the medicine remains and is wasted.
