  1. FORMULATION OF A FAST-DISSOLVING KETOPROFEN LYOPHILIZED TABLET I.S. Ahmed a,*, M.M. Nafadi a, F.A. Fatahalla b a Department of Pharmaceutics and Industrial Pharmacy, Faculty of Pharmacy, Cairo University, Egypt. b National Organization for Drug Control and Research, Cairo, Egypt.

  2. AIM OF WORK The objective of the current work was the improvement of the solubility and dissolution rate of poorly water-soluble ketoprofen by formulating a fast-dissolving tablet of ketoprofen using highly water soluble materials and a freeze-drying technique.

  3. METHOD OF PREPARATION The tablet was prepared by mixing ketoprofen with highly soluble carrier materials namely gelatin, glycine and sorbitol. The suspension was poured in blisters packs and freeze dried in a Novalyphe- NL 500 Freeze Dryer.

  4. CONCLUSION • We demonstrated that a lyophilized ketoprofen tablet made of widely used, safe, water-soluble excipients showed much better solubility and much faster dissolution when compared to the plain drug or the PM. These results were attributed to the formation of an amorphous state of the drug in the porous lyophilized matrix. Such dosage form could be very beneficial for use in pediatric and geriatric patients and those patients who find it difficult to swallow tablets and capsules.
