What is a pharmacokinetic drug interaction?
Pharmacokinetic interactions. These occur when one drug alters the absorption, distribution, metabolism, or excretion of another, thus increasing or decreasing the amount of drug available to produce its pharmacological effects.
What are the four pharmacokinetic processes related to drug interaction?
There are four main components of pharmacokinetics: liberation, absorption, distribution, metabolism and excretion (LADME). These are used to explain the various characteristics of different drugs in the body.
What are drug interactions?
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.
How do you read drug interactions?
A drug interaction is a change in the effect of a drug when it is taken with another drug, food, or substance. Because medications are prescribed to treat specific illnesses or symptoms, such changes mean that the drug is no longer effective, and in many cases, it could become very dangerous.
What are the different types of drug interactions?
There are three types of drug interactions:
- Drug-drug interaction: A reaction between two (or more) drugs.
- Drug-food interaction: A reaction between a drug and a food or beverage.
- Drug-condition interaction: A reaction that occurs when taking a drug while having a certain medical condition.
What are the four principles of pharmacokinetics?
Four processes encompass the pharmacokinetics of a medication. They are absorption, distribution, metabolism, and excretion. Each of these processes is influenced by the route of administration and the functioning of body organs.
