CHALLENGE:
Achieving uniform particle size distribution of API in tablet formulations is essential for consistent dosage and effective treatment. Variability in particle size can lead to dosage inconsistencies and affect the performance of the medication. The challenge was to precisely analyse and optimize the API particle size distribution to enhance the quality and reliability of the tablets.
SOLUTION:
To tackle the challenge of API particle size distribution, we implemented Raman spectroscopy, a powerful analytical technique that provides detailed insights into the distribution and characteristics of API particles. The solution involved in the following
➢ Raman Mapping of API
➢ Analysis of API Particle Size Distribution
➢ Excipients Raman spectra
➢ Tablet Examination
