摘要
Purpose: This study aimed to formulate an orally disintegrating tablet (ODT) containing both baclofen and meloxicam together for treating osteoarthritis. Methods: Direct compression method was used to prepare ODTs using three types of co processed excipients (Prosolv ODT G2 (R), F-melt (R), and Pharmaburst (R) 500). ODTs were evaluated according to weight variation, thickness, friability, hardness, drug content, wetting time, in-vitro disintegration time, in-vitro dissolution test, and palatability. To enhance the in-vitro dissolution of meloxicam and palatability of ODT, a six sigma methodology was used, and an improvement phase was established where ODTs were prepared using lyophilization and levigation techniques. Finally, a pharmacokinetic study of the improved ODT was accomplished in comparison to the conventional oral tablet. Results: Pharmaburst-based formula (F4) showed the shortest wetting time and, consequently, the shortest disintegration time and the highest percentage of drug dissolved within 3 min compared to the other formulae. All the improved ODTs had a bitterness taste score vary from (0) palatable and (+1) tasteless. The current sigma level was 3.628 sigma and 3.33 sigma for palatability and solubility of ODT, respectively, which indicated the process was successfully improved compared with the previous sigma level of 2.342 sigma of both processes. Pharmacokinetic study of the improved ODTs showed a significant decrease of Tmax to 120 and 30 min instead of 180 and 120 min for meloxicam and baclofen, respectively. Conclusion: ODTs were successfully improved using the six sigma methodology, the pharmacokinetic parameters of both drugs were enhanced due to rapid absorption through the oral mucosa.
