Top best answers to the question «Why would the use of antacids affect the drug absorption»

Antacids interfere with gastrointestinal drug absorption by either increasing or decreasing the rate at which a drug is absorbed, or the total quantity absorbed. Antacids influence drug absorption by alteration of ionization state or solubility, factors dependent upon pH.

FAQ

Those who are looking for an answer to the question «Why would the use of antacids affect the drug absorption?» often ask the following questions:

❓ Can inflammation affect drug absorption?

Inflammation has been shown to reduce the activity of both drug metabolizing enzymes and transporters [5,6,7,8].

❓ How aging affect drug absorption?

Ageing is associated with a reduction in first-pass metabolism. This is probably due to a reduction in liver mass and blood flow [52]. As a result, the bioavailability of drugs undergoing extensive first-pass metabolism such as propranolol and labetalol can be significantly increased [53–55].

Question from categories: drug interactions

❓ What factors affect drug absorption?

Drug absorption depends on the lipid solubility of the drug, its formulation and the route of administration. A drug needs to be lipid soluble to penetrate membranes unless there is an active transport system or it is so small that it can pass through the aqueous channels in the membrane.

How does gi motility affect drug absorption?

How does grapefruit juice affect drug absorption?

drug food interactions grapefruit juice grapefruit drug interactions chart

Many drugs are broken down (metabolized) with the help of a vital enzyme called CYP3A4 in the small intestine. Grapefruit juice can block the action of CYP3A4, so instead of being metabolized, more of the drug enters the blood and stays in the body longer. The result: too much drug in your body.

Absorption. Both the lipid solubility of the drug and the pH of the gastric tissues affect drug absorption from the GI tract. Lipid-soluble drugs are absorbed more rapidly than non–lipid-soluble drugs. Gastric fluid has a pH of approximately 1.4.

The most common mechanism of absorption for drugs is passive diffusion. This process can be explained through the Fick law of diffusion in which the drug molecule moves according to the concentration gradient from a higher drug concentration to lower concentration until equilibrium is reached.

How does ionization affect absorption of drugs?

acidic drugs list ionized and unionized drugs

Ionized (or charged) drugs are not absorbed as efficiently as un-ionized drugs are. Practically speaking, this means that if taken orally, a drug that is a weak acid will be absorbed primarily in the acidic environment; whereas, a drug that is a weak base will be absorbed in the alkaline environment small intestines.
