Process to manufacture effervescent tablets: air forced oven melt granulation

Area of Science:

• Pharmaceutical Technology
• Materials Science

Background:

• Effervescent granules require specific manufacturing processes for optimal tablet formation.
• Traditional granulation methods can be complex and time-consuming.

Purpose of the Study:

• To investigate the application of air forced oven melt granulation for single-stage effervescent granule manufacture.
• To identify key process parameters influencing granule and tablet properties.

Main Methods:

• Melt granulation of anhydrous citric acid and sodium bicarbonate in an air forced oven.
• Systematic variation of process parameters including PEG 6000 concentration and residence time.
• Evaluation of granule and tablet characteristics, including compression behavior.

Main Results:

• Process parameters like PEG 6000 concentration, residence time, and lubricant efficiency significantly impacted granule and tablet characteristics.
• Optimized formulations (B2 and E2) processed for 30 minutes exhibited ideal compression properties.
• Granules demonstrated stability for 7 days under specified environmental conditions (60% RH/18°C).

Conclusions:

• Air forced oven melt granulation is a dry, simple, rapid, effective, economical, and reproducible process for effervescent granules.
• The method is well-suited for producing effervescent tablets with optimal compression characteristics.
• Careful control of process parameters is crucial for achieving desired product quality.
