Physiologically Based Pharmacokinetic Modeling and Mechanistic In Vitro-In Vivo Correlation for Long-Acting Injectable Suspension
Long acting injectable (LAI) suspensions demonstrate extended release by forming depots at the injection site (subcutaneous or intramuscular), from which poorly soluble drugs are slowly dissolved and absorbed into the systemic circulation
When Mechanistic IVIVC Falls Short: The Case for IVIVR in Oral Drug Delivery
Traditional IVIVC is robust for ER formulations where dissolution is rate limiting.
