Formulation development of intermediate release Nimesulide tablets by CCRD for IVIVC studies

Area of Science:

• Pharmaceutical Sciences
• Materials Science

Background:

• Optimizing drug delivery systems is crucial for therapeutic efficacy.
• Nimesulide intermediate release tablets require careful formulation for desired release profiles and stability.

Purpose of the Study:

• To develop and characterize intermediate release Nimesulide tablets using a central composite design (CCRD).
• To evaluate the impact of excipients (Avicel, HPMC, magnesium stearate) and mixing times on micromeritic properties and tablet characteristics.
• To assess the stability and dissolution profiles of optimized Nimesulide formulations.

Main Methods:

• Micromeritic properties (bulk density, tap density, compressibility, angle of repose, Hausner's ratio) of placebo and Nimesulide blends were compared.
• A central composite design (CCRD) was employed to optimize tablet formulations with varying excipient concentrations.
• Physicochemical properties, dissolution patterns, and stability studies were conducted using R Gui for analysis.

Main Results:

• Nimesulide presence enhanced micromeritic properties, with 9 minutes identified as the optimal mixing time.
• Tablet hardness correlated positively with relative density in Nimesulide-containing tablets.
• The F16 formulation exhibited the best release pattern and stability, predicting a shelf life of 72 months.

Conclusions:

• The study successfully developed stable intermediate release Nimesulide tablets through systematic formulation optimization.
• The optimized formulation (F16) demonstrates significant potential for extended shelf life and predictable drug release.
• This research provides a cost-effective approach for developing robust Nimesulide tablet formulations.
