    Entrance of the drug into the blood stream.
  21. Factors That Affect Absorption
    • Solubility of Drug
    • Site of Administration, Oral, Parenteral, Topical
    • Drug Ionization, un-ionized drug enhanced drug absorption.
    • Drugs already in solution will be absorbed faster
    • The smaller the particle size of the drug, the faster the rate of dissolution and absorption
  22. Distribution
    The process by which a drug; is carried to the various tissues and organs of the body.
  23. Metabolism
    The enzymes responsible for drug metabolism
  24. Elimination
    The process by which materials, including drugs, are removed from the body to the external environment.
  25. Sites of Excretion
    Kidney, Feces, Lung, Sweat, Tears, Saliva., Breast Milk
  26. What is first pass metabolism? What routes of administration can be used to avoid this effect?
    After oral administration, all drugs are carried by the bloodstream to the liver before they are distributed to other tissues or organs. Some drugs are metabolized significantly on this first pass through the liver. This is known as the first-pass metabolism. It can greatly reduce the amount of active drug that reaches the site of action.
  27. What is half life?
    the time it takes 1/2 of the drug in the body to be eliminated.
  28. List several reasons for coating tablets.
    • Taste, bad taste and foul odors
    • Stability: oxygen, light, or moisture in the atmosphere
    • Prevent Contact with Drug: Aspirin - Ecotrin?
    • Separate Active Ingredients: Two ingredients
    • Control Rate of Release: alter the rate of release of a drug
    • Control the Site of Release: specific sites
    • Improve Appearance: have a visually pleasing product
    • Prevent Loss of Volatile Ingredients
  29. What are the reasons for enteric coating?
    • Enhance drug stability and to control the rate of drug release.
    • Prevent gastric degradation or digestion
    • Prevent gastric mucosal irritation (Ecotrin?, Ery-Tab?)
    • Prevent dilution of drug prior to reaching its site of action (Azulfidine?)
    • Provide delayed action
    • Control or monitor physiological location of drug delivery
  30. What is compliance? How do coatings and extended action preparations relate to compliance?
    A patient��s adherence to the dose schedule and other particular requirements of the specified regimen.
