Degradation Kinetics Quantitation

Degradation kinetics quantitation characterises pharmaceutical decomposition rates employing mathematical models. Zero-order kinetics show constant degradation regardless of concentration. First-order kinetics follow exponential decay common for many drugs. Temperature dependence follows Arrhenius relationships predicting shelf-life. Humidity acceleration demonstrates moisture sensitivity.

Stress testing establishes representative degradation profiles. Stability-indicating methods quantitate degradation products. Accelerated studies extrapolate to real-time conditions. Regulatory submissions justify shelf-life predictions. Non-linear kinetics complicate predictions requiring careful assessment. Emerging analytical techniques provide improved degradation quantitation.
