How does medicine spread in the body?
Drugs undergo four stages within the body: absorption, distribution, metabolism, and excretion. After a drug is administered, it is absorbed into the bloodstream. The circulatory system then distributes the drug throughout the body. Then it is metabolized by the body.
How does drug travel through the body?
How does medication enter the bloodstream? The vast majority of medications are taken orally and are broken down within the gastrointestinal tract. Once the medication arrives, it is broken down by stomach acids before it passes through the liver and then enters the bloodstream.
How are drugs distributed throughout the body?
Distribution in pharmacology is a branch of pharmacokinetics which describes the reversible transfer of a drug from one location to another within the body. Once a drug enters into systemic circulation by absorption or direct administration, it must be distributed into interstitial and intracellular fluids.
How does a medicine work in the body?
A lot of medicines are swallowed, either as a pill or a liquid. Once the medicine is swallowed, the digestive juices in the stomach break it down, and the medicine can pass into the bloodstream. Your blood then carries it to other parts of your body where the medicine works best.
How is medicine distributed in the body?
After a drug enters the systemic circulation, it is distributed to the body’s tissues. Distribution is generally uneven because of differences in blood perfusion, tissue binding (eg, because of lipid content), regional pH, and permeability of cell membranes.
How does a drug distribute to the body?
The average circulation time of blood is 1 minute. As the blood recirculates, the drug moves from the bloodstream into the body’s tissues. Once absorbed, most drugs do not spread evenly throughout the body.
What organs do medications pass through?
Most drugs must pass through the liver, which is the primary site for drug metabolism. Once in the liver, enzymes convert prodrugs to active metabolites or convert active drugs to inactive forms.
