What is the risk associated with exceeding the MTC of a drug?

Exceeding the maximum therapeutic concentration (MTC) of a drug primarily poses a risk of adverse effects. The MTC represents the upper limit of drug concentration in the body at which the medication remains effective without causing harmful side effects. When this threshold is surpassed, the likelihood of experiencing toxic effects or harmful reactions increases significantly.

For many medications, particularly those with a narrow therapeutic index, even minor increases in concentration can lead to severe complications. This underscores the importance of closely monitoring drug levels and adhering to prescribed dosages to prevent potentially serious health implications. Understanding the MTC and the associated risks helps pharmacy technicians ensure patient safety and promote effective medication management.
