Abstract Objective: To prepare rapamycin suppository, and to evaluate its quality. Methods: Rapamycin was used as active ingredient, polyethylene glycol 2000 and polyethylene glycol 4000 were used as main substrates. The suppositories were made using hot melt process method, and the drug content, weight difference, melting time, drug release with time were evaluated. Results: Polyethylene glycol suppository with rapamycin appeared white and translucent. Good hardness could be maintained at room temperature. The drug content, weight variation and melting time limit matched the requirements for the suppository. More than 75% of the loaded drug in the suppositories was released at about 25 min in the medium. Conclusion: This preparation of rapamycin polyethylene glycol (PEG) suppository can reach the quality requirements of Chinese pharmacopoeia, and may be developed as a new formulation of rapamycin.
