"ABSORPTION 2" | Intravenous administration does not have an ABSORPTION step. |
"ABSORPTION 3" | When gastric contents SLOWS DOWN, it will take longer to move through the bowel, therefore increasing absorption. |
"ABSORPTION 4" | Metabolizing enzymes in the GI tract wall will DECREASE absorption. |
"ENZYMES"? | Complex proteins that causes chemical reactions in other substances. |
"ENZYMES INHIBITION"? | Typically occurs in the liver. |

"ENZYME INDUCTION"? | The increase in ENZYMES activity that results in greater metabolism of drugs. |
KIDNEYS | The KIDNEYS filter the blood and remove waste materials including drugs and metabolites. |
"BIOAVAILABILITY" | The relative amount of an administered dose that reaches the general circulation and the rate at which it occurs |
"BIOEQUIVALENT DRUG PRODUCTS" | DRUGS PRODUCTS that contain identical amounts of the same active ingredients in the same dosage form, so they have same bioavailability. |
"PHARMACEUTICAL ALTERNATIVE" | Same active ingredient. Amounts can be different. Dosage form can be different. Inactive ingredient can be different. |
"ORANGE BOOK" FDA? | The FDA requires drug manufacturers to perform bioequvalency studies on their products before they are approved for marketing. |
"MINIMUM EFFECTIVE CONCENTRATION"? | The blood concentration needed of a drug to produce a response. |
"PASSIVE DIFFUSION"? | Is the most common way an orally administered drug is distributed through the body.The movement |
"PASSIVE DIFFUSION 2"? | The movement of drugs from an area of higher concentration to a lower concentration. |
"SELECTIVE ACTION"? | The characteristic of a drug that makes its action specific to certain receptors and the tissues they effect. |
BINDING | Drugs BIND to may proteins in blood and tissue. |
