Pharmaceutical Quality Control via FT-IR

Significance of the Topic

Pharmaceutical quality control under GMP and GLP regulations is critical to ensure the safety and efficacy of drug products. Fourier-transform infrared spectroscopy provides a rapid, non-destructive approach to identify and quantify active pharmaceutical ingredients, excipients, polymorphs and contaminants in various dosage forms.

Study Objectives and Overview

This article reviews the application of Bruker’s FT-IR instrumentation and OPUS software for compliance-driven QC tasks, including material verification, particle contamination analysis and mapping of component distribution.

Methodology and Instrumentation

FT-IR spectroscopy employs infrared light to induce molecular vibrations that generate unique absorption spectra. Attenuated total reflection (ATR) enables surface analysis in seconds without sample preparation. FT-IR microscopy provides micrometer spatial resolution for mapping APIs, excipients and inclusions. OPUS software ensures data integrity with audit trails, user management, 21 CFR part 11 compliance and automated spectral matching. The OPUS Validation Program delivers comprehensive instrument qualification (IQ, OQ, PQ) protocols.

Main Results and Discussion

Key findings include distinct infrared fingerprints of acetylsalicylic acid, talc, mannitol and glycerol across the 4000–600 cm-1 range; rapid identification of raw materials and packaging; detection and chemical characterization of microscopic contaminants; and automated library search for sample verification. Software-driven validation and traceability support regulatory audits.

Benefits and Practical Applications

• Non-destructive analysis with minimal or no sample preparation and results in seconds
• Microscale resolution for contamination and polymorphism studies
• Qualitative and quantitative evaluation of powders, tablets, liquids, creams and coatings
• Integrated compliance features, audit trails and secure data archiving

Future Trends and Applications

Advances may include artificial intelligence integration for enhanced spectral interpretation, focal plane array imaging for faster chemical mapping, online process monitoring for real-time quality control and expanded spectral libraries for complex formulations.

Conclusion

FT-IR spectroscopy combined with validated OPUS software offers a robust, compliant solution for pharmaceutical quality control, delivering rapid, accurate identification, quantification and spatial analysis essential to meet stringent regulatory standards.
