Overview
PK/PD modeling is a powerful, data-driven approach that integrates two key disciplines: Pharmacokinetics (PK), which studies how a drug moves through the body (absorption, distribution, metabolism, and excretion), and Pharmacodynamics (PD), which examines the drug's effect on the target pathogen. By establishing a quantitative relationship between drug exposure (PK) and antifungal effect (PD), we can predict drug efficacy, determine optimal dosing regimens, and identify potential risks in preclinical and clinical stages.
Our PK/PD modeling services provide a sophisticated understanding of your compound's behavior, allowing you to:
-
Select the most promising candidates
-
Design more effective and safer clinical trials
-
Reduce the need for extensive in vivo studies
-
Obtain a competitive advantage in a challenging market

Mechanism of Action: How PK/PD Modeling Works for Antifungals
The core of our service lies in understanding the complex interplay between drug concentration and microbial response. We utilize a range of mathematical models to describe this relationship, often focusing on key PK/PD indices that correlate with antifungal efficacy:
-
AUC/MIC (Area Under the Curve to Minimum Inhibitory Concentration Ratio): This index is a measure of total drug exposure over time relative to the potency of the drug against the pathogen. It is often the primary predictor of efficacy for time- and concentration-dependent drugs.
-
Cmax/MIC (Peak Concentration to Minimum Inhibitory Concentration Ratio): This ratio is critical for concentration-dependent killing, where a high peak concentration is required for effective pathogen clearance.
-
T>MIC (Time Above Minimum Inhibitory Concentration): This index represents the duration for which the drug concentration remains above the MIC. It is crucial for time-dependent killing where sustained exposure is key.
By fitting experimental data (in vitro time-kill curves, in vivo animal model data) to these models, we can determine the optimal values for these indices, which can then be used to predict effective human doses.

FAQs
What is the typical cost of a PK/PD modeling project?
The cost varies depending on the scope and complexity. We provide a detailed, project-based quote after the initial consultation.
What data do I need to provide?
We need a combination of PK data (e.g., plasma concentration-time profiles) and PD data (e.g., fungal burden, CFU counts). The more detailed the data, the more robust the model.
Can you help us design the animal study to generate the data?
Yes, we offer full-service support, including protocol design and coordination with a network of trusted partners for animal studies.
Is PK/PD modeling accepted by regulatory agencies?
Yes, it is a well-established and highly valued component of drug development and is often requested or recommended by regulatory agencies to justify dosing regimens.
