Which of the following are factors affecting bioavailability quizlet?

Summary of physical factors affecting – dissolution:

  • Solubility in GI media.
  • Effective surface area available for dissolution.
  • Diffusion coefficient.
  • Thickness of boundary layer.
  • Concentration of drug in bulk.

What causes bioavailability?

Bioavailability refers to the extent and rate at which the active moiety (drug or metabolite) enters systemic circulation, thereby accessing the site of action. Bioavailability of a drug is largely determined by the properties of the dosage form, which depend partly on its design and manufacture.

What factors affect the bioavailability of vitamins and minerals?

Suzanne Cole at the University of Michigan, bioavailability is influenced by several factors including diet, nutrient concentration, nutritional status, health, and life-stage.

What are the factors that affect drug absorption and bioavailability?

Factors affecting Absorption of Drugs

  • Formulation.

How does absorption affect bioavailability?

5.1 Definition. Absorption is the movement of drug from the site of drug administration to the systemic circulation. Bioavailability is the extent to which absorption occurs. In other words, bioavailability is the fraction of the administered drug that reaches the systemic circulation in the unchanged form.

What are 4 factors that affect absorption of a drug?

These include:

  • physicochemical properties (e.g. solubility)
  • drug formulation (e.g. tablets, capsules, solutions)
  • the route of administration (e.g. oral, buccal, sublingual, rectal, parenteral, topical, or inhaled)
  • the rate of gastric emptying.
