Kinetic Solubility Measurement

Kinetic solubility measurement quantitates rapid dissolution rates prior to thermodynamic equilibrium establishment. Nephelometry detects precipitation as compound concentration exceeds solubility. Kinetic solubility often exceeds thermodynamic solubility temporarily. Supersaturation conditions enable higher concentrations initially. Crystallisation converts supersaturated solutions to stable polymorphs.

Formulation strategies exploit kinetic solubility increasing bioavailability. Amorphous solid dispersions maintain kinetic solubility temporarily. Stabilising polymers inhibit crystallisation. Regulatory submissions justify solubility characterisation. Post-approval monitoring confirms bioavailability maintenance.
