Clinical pharmacokinetics pharmacy handbook /

Abstract

The Clinical Pharmacokinetics Pharmacy Handbook, 2nd Edition, is a practical reference that guides pharmacists in applying clinical pharmacokinetics to optimize drug therapy and improve patient outcomes. Published by the Pharmacy Practice & Development Division of the Malaysian Ministry of Health, the handbook serves as a training and practice guide for pharmacists involved in clinical pharmacokinetics and therapeutic drug monitoring (TDM).

The handbook explains how pharmacokinetics—the relationship between drug dosage and drug concentration in the body over time—affects therapeutic efficacy and safety. It emphasizes the importance of understanding the processes of absorption, distribution, metabolism, and elimination (ADME) in order to individualize drug dosing and maintain drug concentrations within the therapeutic range while avoiding toxicity.

The second edition updates earlier guidance by incorporating current clinical information and revised therapeutic ranges for several drugs. It also expands the list of medicines requiring therapeutic drug monitoring, adding lithium and revising recommendations according to modern clinical practice. The handbook includes real clinical case scenarios and calculation examples to help pharmacists understand pharmacokinetic concepts and apply them in clinical decision-making.

Key chapters focus on drugs that commonly require pharmacokinetic monitoring, such as aminoglycosides, vancomycin, digoxin, methotrexate, carbamazepine, phenytoin, valproic acid, and immunosuppressants. These sections guide dosage adjustments, interpretation of serum drug concentrations, and management of toxicity.

Overall, the handbook aims to support pharmacists in delivering effective clinical pharmacokinetics services, ensuring safe and individualized medication therapy, and enhancing the quality of patient care in healthcare institutions.
