Where Modeling Drives Discoveries
?
○???? Clinical Pharmacometrics : Application of Pharmacometrics in the bedside for assisting in? precision pharmacotherapy. We conduct clinical pharmacokinetics studies to collect pharmacokinetic data in patient- population that includes special populations like neonates, renal transplant patients and oncology patients. The data will be analyzed using appropriate pharmacometric methods to derive the pharmacokinetic parameters and nomograms. These nomograms can aid in precise dosing as per the requirements of patients.
?
○???? Model informed drug development : Clinical pharmacology based decisions drive the drug development pathways and pharmacometrics is an important tool in clinical pharmacology that can be helpful in driving the progression of drug development. Pharmacometrics can also be applied in the drug development stages spanning from the preclinical to clinical stages.
?
Training and mentoring : Centre focuses on developing the talent base needed for clinical pharmacology and pharmacometrics. Centre runs certificate courses, offering fellowships in pharmacometrics and conducting workshops on relevant focus areas of drug development and clinical pharmacometrics. Centre envisages for the conduct of national conferences in the area of drug development and pharmacometrics.?
