Benefits of Therapeutic Drug Monitoring

- Facilitates rapid determination of the appropriate dosing regimen.

The patient's specific pharmacokinetic parameters are used to determine the appropriate dose required to achieve plasma drug conc within the therapeutic range.

- Evaluates existing dosage regimen.

This is achieved by determining if the patient's dosing regimen produces plasma conc within the therapeutic range.

- Protects against drug toxicity and serious adverse effects.

Maintaining the plasma drug conc within the therapeutic range will decrease the probability of developing serious adverse effects.

- Distinguishes between pharmacokinetic and pharmacological causes of therapeutic failure.

Determination of plasma drug conc can help in determining if the therapeutic failure is caused by inadequate drug dose or by the use of ineffective drug.
