Abstract

Background: Pharmaceutical technology transforms medicinal substances into stable, acceptable, palatable, therapeutically useful and reproducible result generating dosage forms. Ayurveda has an extensive pharmaceutical tradition encompassing Panchavidha Kashaya Kalpana, Sneha Kalpana, Avaleha, Vati, Asava-Arishta, and mineral/herbo-mineral preparations. Contemporary pharmaceutical technology employs unit operations such as size reduction, mixing, filtration, extraction, evaporation, drying, and distillation, supported by process validation, Quality by Design (QbD), Process Analytical Technology (PAT), analytical fingerprinting, and stability assessment. Methods: A narrative literature review was undertaken using relevant literature from PubMed-indexed publications, Google Scholar-oriented scholarly sources, WHO publications, and pharmaceutical- quality guidelines was additionally considered. Classical Ayurvedic pharmaceutical concepts were interpreted alongside contemporary pharmaceutics without presuming direct equivalence between traditional and modern processes. Results and Discussion: The review demonstrates substantial conceptual convergence between Ayurvedic pharmaceutical operations and contemporary engineering principles. Classical trituration, levigation, filtration, heating, extraction, concentration, fermentation, calcination, and dosage-form conversion can be evaluated using measurable process variables including particle size, temperature, processing time, shear, solvent-to-drug ratio, moisture, mixing intensity, and drying kinetics. However, process equivalence requires experimental validation because classical procedures may incorporate qualitative and multidimensional endpoints. Contemporary analytical and manufacturing technologies can enhance identity, purity, consistency, process control, stability, and dosage-form performance. Conclusion: Integration rather than replacement represents the most appropriate pathway for modernization of Ayurvedic pharmaceutics. Incorporation of critical material attributes, critical process parameters, quality attributes, analytical standardization, validation, and safety monitoring can improve reproducibility and scientific communication while preserving the pharmacotechnical identity of Ayurvedic formulations.
