Popis: To develop a clotrimazole-loaded solid suppository with poloxamer and propylene glycol, the melting points of various formulations composed of poloxamer 188 (P 188) and propylene glycol were investigated. The dissolution study of clotrimazole delivered by the suppository composed of P 188 and propylene glycol was performed. The mixtures composed of P 188 and propylene glycol were homogeneous. Propylene glycol affected the melting points of poloxamer mixtures. In particular, the mixture [P 188/propylene glycol (70/30%)] with the melting point of about was a solid form at room temperature and instantly melted at physiological temperature. Furthermore, propylene glycol affected greatly the dissolution rates of clotrimazole from the suppository. Dissolution mechanism analysis showed the dissolution of clotrimazole was proportional to the time. Our results indicated that the solid suppository with P 188 and propylene glycol would be a candidate of rectal dosage form for clotrimazole.
