Abstract
To develop a poloxamer-based solid suppository with poloxamer mixtures, the melting points of various formulations composed of P 124 and P 188 were investigated. To investigate the effect of poloxamer to the dissolution and dissolution mechanism of diclofenac sodium from the suppository the dissolution of diclofenac sodium delivered by the poloxamer-based suppository was performed. Furthermore, to investigate the mucoadhesive property of the poloxamer-based solid suppository, the identification test in the rectum was carried out after its rectal administration in rats. The poloxamer mixtures composed of P 124 and P 188 were homogeneous. Very small amounts of P 188 affected the melting points of poloxamer mixtures. In particular, the poloxamer mixture [P 124/P 188 (97/3%)] with the melting point of about 32℃ was a solid form at room temperature and instantly melted at physiological temperature. Furthermore, very small amounts of P 188 in the poloxamer-based suppository hardly affected the dissolution rates of diclofenac sodium from the suppository. Dissolution mechanism analysis showed the dissolution of diclofenac sodium was proportional to the time. At 4 h after administration, the blue color of poloxamer-based suppository [diclofenac sodium/poloxamer mixture (2.5/97.5%)] with the P 124/P 188 ratio of (97/3%) and blue lake in the rectum was faded. However, the position of suppository in the rectum did not significantly change with time. Thus, it retained in the rectum for at least 4 h. Our results indicated that the poloxamer-based solid suppository with P 124 and P 188 would be a candidate of rectal dosage from for diclofenac sodium.
