Comprehensive High-Yield NUR 210 Pharmacology Study Guide: Detailed Mechanisms, Indications, Pharmacokinetics, Pharmacodynamics, Nursing Considerations, Side Effects, Adverse Reactions, and Patient Education Across CNS Medications, Analgesics, Anti-Inflammatories, Antigout, Antipsychotics, Antidepressants, Mood Stabilizers, and Seizure Drug Exam Questions Verified and Provided with Complete A+ Graded Rationales Latest Updated 2026 Peak Highest concentration of the drug Trough The lowest plasma concentration of a drug and it measures the rate at which the drug is eliminated Onset The time it takes for a drug to reach the minimum effective concentration Duration The length of time the drug exerts therapeutic effects Agonist Produces a desired response Antagonist Block a desired response Additive The sum of the effects of the two drugs Synergistic effect When 2 or more drugs are given together, one drug can have a clinical effect substantially greater than that of either drug alone Half Life The time it takes for the amount of the drug in the body to be replaced by half Potentiation When the combined effects of two different drugs exceed the expected additive effect of each of the drugs Pharmacokinetics Process of drug movement through the body to achieve necessary drug reaction Protein Binding When 2 highly protein drugs are administered they compete for protein binding sites leading to an increase in free drug being released into the circulation Distribution The movement of the drug from the circulation to body tissues where it is being absorbed in the body Bioavailability Refers to the % of the administered drug available for activity Drug Excretion Elimination of the drug from the body through the kidneys, bile, lungs, saliva, sweat, and breast milk Pharmacodynamics Is the study of the effects of the drug on the body Side Effects Are 2nd effects of drug therapy; all drugs have some form of side effects even with normal dosage Adverse Reaction Are unintentional, unexpected reactions to drug therapy that occurs at normal drug dosages Benzodiazepine Increase the action of inhibitory neurotransmitter gamma-aminobutric acid (GABA) receptors/neuron excitability Non-Benzodiazepines CNS depression neurotransmitter inhibition Local Anesthetics Block pain at the site where the drug is administered by preventing the conduction of nerve impulses NSAIDS Inhibit or block both COX-1 and COX-2; used to treat pain, inflammation, and fever Salicylates Used to treat pain, fever, inflammation, and antiplatelet therapy Lidocaine A local anesthetic used to block pain at the site of administration Zolpidem A non-benzodiazepine used for insomnia Celecoxib Inhibits COX-2, providing protection for the stomach lining Ibuprofen An NSAID that inhibits both COX-1 and COX-2 Drowsiness GI Upset Aspirin Inhibits prostaglandin synthesis, hypothalamic heat regulator center, and platelet aggregation Aspirin Adverse Reactions Bleeding, Hearing loss/tinnitus, GI ulceration Aspirin Indications Used to Treat Gout and Hyperuricemia Allopurinol
