  2. Types
    1. Pharmacokinetic (most common)
      1. Two drugs compete for the same Mechanism of absorption, distribution, metabolism or excretion (ADME)
      2. Results in a change in one or both drugs concentration at the site of their action when both agents are taken
      3. Typically involves Cytochrome P450, UGT, P-Glycoprotein or OATP
      4. Often drug dosage changes and monitoring are sufficient for low to moderate risk interactions
    2. Pharmacodynamic
      1. One drug directly blocks or exacerbates another drugs activity without modifying drug concentrations
      2. Offending drug, typically must be stopped (drug dosage modifications typically do not resolve interaction)
  3. Causes: Food Interactions

Food Interactions (C0242784)

Definition (CSP) physical chemical interaction between nutrients, or between nutrients and other components of the diet or other compounds, including desirable or undesirable results; nutrients are substances that can be metabolized by an organism to give energy and build tissue; for the concept of nutrients interacting with drugs use NUTRIENT DRUG INTERACTION.

Drug Interactions (C0687133)

Definition (NCI_NCI-GLOSS) A change in the way a drug acts in the body when taken with certain other drugs, herbals, or foods, or when taken with certain medical conditions. Drug interactions may cause the drug to be more or less effective, or cause effects on the body that are not expected.
Definition (NCI) Alteration of the disposition and/or effect of a drug, owing to the presence of another factor such as a second drug, or food.
Definition (MSH) The action of a drug that may affect the activity, metabolism, or toxicity of another drug.
Definition (PSY) Chemical and/or pharmacological reactions of drugs in combination, including agonistic and antagonistic interactions.
Definition (CSP) physical chemical interaction between drugs and other compounds, including other drugs, particularly in biological systems.
