Abstract
The invention relates to a pharmaceutical composition, which comprises liquid oil, at least one compound as shown in the following formula I and at least one pharmaceutical active component. The pharmaceutical composition can be used for a sustained release preparation system, so that the medicine is in a semi-solid or solution form at normal temperature, the semi-solid preparation can be directly used as a medicine storage bank at the administration part, the liquid preparation is subjected to phase change to form the medicine storage bank after the administration part is in contact with body fluid, and meanwhile, the medication safety and tolerance are improved.
