Interaction with Other Medications: Potential Risks and Precautions

Types of interactions: interactions between medicines can occur in several ways, such as the alteration of absorption, distribution, metabolism and excretion of the drug. These interactions can potentially lead to a therapeutic failure or a higher risk of side effects. Some common types of interactions include:

  1. Pharmacokinetic interactions: These interactions imply changes in the movement of drugs within the organism. A medication can affect the way another is absorbed, metabolizes or eliminates. This can lead to an alteration of blood levels of either drug.
  2. Pharmacodynamic interactions: These interactions occur when two or more drugs are used jointly with similar mechanisms of action. The combined effect can be additive, synergistic or antagonistic. Depending on interaction, it can enhance the therapeutic effect or increase the risk of adverse effects.
