2. Core Steps in Reverse Engineering for Development of Generic Drugs
Reverse engineering follows a structured, multi-step analytical approach designed to reproduce the original drug’s quality and performance.
| Step | Objective | Analytical Techniques Used |
|---|---|---|
| Deformulation | Identify excipients and APIs | LC–MS, FTIR, GC–MS |
| Quantitative Analysis | Determine component ratios | HPLC, UV–Vis |
| Functional Characterization | Evaluate physical properties | DSC, XRD, Rheometry |
| Process Replication | Reconstruct manufacturing method | DOE, QbD modeling |
| Performance Testing | Compare bioequivalence | Dissolution profiling, PK studies |
Each of these steps helps scientists understand how the RLD performs, ensuring that the generic version matches all key quality parameters. ResolveMass’s Deformulation and Characterization Services ensure accuracy in identifying ingredients that affect drug stability, performance, and bioavailability.
3. Analytical Techniques in Reverse Engineering of Pharmaceuticals
Advanced analytical tools and skilled expertise are essential for accurate deformulation. Common techniques include:
