Complete Guide to Cyclosporine Pharmacokinetics
Overview
Cyclosporine is a Small Molecule used in the Transplant therapeutic area. It is indicated for Organ Transplant Rejection. Gamma absorption PK model for cyclosporin (Neoral). Therapeutic drug monitoring with C0, C2, and AUC targets.
Mechanism of Action
Cyclosporine exerts its pharmacological effect by targeting Calcineurin. As a Small Molecule, it modulates this target to achieve therapeutic efficacy in Organ Transplant Rejection. Understanding the target engagement is critical for interpreting the pharmacokinetic-pharmacodynamic (PK/PD) relationship and optimizing dosing regimens.
Key Pharmacokinetic Parameters
The following parameters are derived from published PopPK models for Cyclosporine:
| Parameter | Value |
|---|---|
| Q | 50.6 L/h |
| CL | 56.2 L/h |
| V1 | 61.3 L |
| V2 | 61.2 L |
| scaling | Allometric (WT^0.75 for CL/Q, WT^1.0 for V) |
| C2 | 800-1400 ng/mL |
| AUC 0 12 | 4400-5500 ng·h/mL |
| C0 trough | 100-200 ng/mL |
Parameters represent typical population estimates from published literature. Individual values may vary.
Dosing & Administration
Cyclosporine is administered via the Oral route. Oral administration involves absorption from the gastrointestinal tract, and bioavailability may be affected by food intake, formulation, and first-pass metabolism.
Dosing recommendations should always follow approved prescribing information. The interactive simulator allows you to explore different dosing scenarios and their impact on drug exposure metrics such as AUC, Cmax, and Ctrough.
Clinical Considerations
In the Transplant therapeutic area, for the treatment of Organ Transplant Rejection, understanding the pharmacokinetics of Cyclosporine is essential for dose optimization and therapeutic drug monitoring. Key clinical factors that may affect Cyclosporine pharmacokinetics include:
- •Body weight and body composition
- •Renal and hepatic function
- •Drug-drug interactions and concomitant medications
- •Age, sex, and genetic polymorphisms
