Document Summary
Achievement of the desired therapeutic goal from drug therapy. Pharmaccotherapeutics is the study of the clinical purpose - the indication - for giving a drug. The desired pharmacotherapeutics can be to induce a cure or prevent a problem. Nurses do need to question all orders if the intended pharmacotherapeutics of a drug does not correlated with the patient"s reason for receiving drug therapy. Pharmacokinetics is the movement of the drug particles inside the body. Absorption is the movement of the drug from the site of administration into the bloodstream. Distribution is the movement of the drug from the site of administration into the bloodstream. Metabolism is the conversion of the drug into another substance or substances. Process by which drugs move through the body. Drug molecules move during all phases of pharmacokinetics. Drugs cross cell membranes in one of the three ways: First, they can pass between the spaces or channels between the molecules in the membrane.
