Agonist
Drugs that bind to a receptor and cause a response.
Analgesics

Antagonist
drugs that bind to receptor sites and prevent a normal response by cell.
Anticoagulant
a medication that prevents blood clotting reducing risk of abnormal thrombi formation
Antiplatelet
a medication that interferes with platelet aggregation.
Barbiturates
sedatives whose mechanism of action includes an increase in affinity between the receptor sites and the neurotransmitter GABA
Bioavailability
the degree to which a drug becomes available at the site of physiologic activity after it is administered.

medications that stimulate the cellular acetylcholine Ach receptors
Contraindications
the conditions under which administering and other wise indicated medication would result in patient harm

over the counter
Parasympatholytics
medications that reduce the actions of the parasumpathetic nervous system
Parasympathomimetics
classification of medication that are agonist to the parasympathetic nervous system
Pharmacodynamics
the actions the drug have on the body
Pharmacology
the study of drugs actions and reaction
Potentiation
the enhancement of one medication as a result of being combined with another
