Therapeutic Drug Monitoring
Therapeutic Drug Monitoring is a branch of clinical pharmacology measures the concentration of a drug in the blood at regular intervals. Its main focus is on drugs with narrow therapeutic window, i.e. drugs that can easily be under-over taken. TDM is used to determine the dose at which a drug will be the most safe and effective. According to medicine, monitoring is analyses of several diseases over time. It can be performed by two ways one by continuously analysing the parameters using medicine monitor and the other by repeatedly performing the tests. Therapeutic agent that causes therapeutic effect to amount that causes toxicity is determined by therapeutic index. Medication with a small therapeutic window must be handled with care, frequently measuring the drug concentration in blood to avoid harm.
