TYPES OF DRUG EFFECTS → overdosage, extension of the desired effect → One of the most common occurrences in drug therapy is the development of adverse effects from simple overdose. In such cases, the patient suffers from effects that are merely an extension of the desired effect. For example, an anticoagulant may act so effectively that the patient experiences excessive and spontaneous bleeding. This type of adverse effect can be avoided by monitoring the patient carefully and adjusting the prescribed dose to fit that particular patient’s needs.

• After a drug is administered, its molecules first must be absorbed into the body; then they make their way to the reactive tissues. If a drug is going to work properly on these reactive tissues, and thereby have a therapeutic effect, it must attain a sufficiently high concentration in the body. • Amount of drug that is needed to cause a therapeutic effect • Basis of the recommended dosage
