QuestionAnswer
The study of drugs and their effects on living organisms Pharmocolgy
what the body does in response to the drugs (e.g., absorption, distribution, metabolism, excretion) is called? Pharmacokinetics
amount of drug (e.g., in milligrams) needed to produce an effect; the more potent an agent is, the lower the dose needed to produce an effect Potentcy
desired effect elicited by drug, independent of dose Efficacy
Side effects fall under the category of adverse reactions, T or F True
effect on an organ other than that intended to be altered (e.g., insomnia resulting from a bronchodilator); dose-related and often predictable side effect
varies from mild rash to anaphylaxis; involves an antigen–antibody reaction (e.g., rash from penicillin); can include urticaria, soft-tissue swelling, and difficulty in breathing; not predictable and not dose-related allergic reaction
Drug has an affinity for a receptor site and binds to it but produces no effect; competitively blocks the effect of the agonist Antagonist
Drug has an affinity for a receptor site and binds to it producing an effect. Agonist
The neurotransmitter for the Parasympathetic Nervous System (PANS) is ? acetylcholine
The neurotransmitter for the Sympathetic Nervous System (SANS) is adrenalin/epinephrine
Which part of the nervous system is active when the body is at ease? parasympathetic
which part of the nervous system is active when the body is experiencing "fight or flight'? sympathetic
drugs that imitate which neurotransmitter are known as parasympathomimetic or cholinergic drugs (P+) acetylcholine
drugs that block or inhibit acetylcholine (P-) are known as what kind of drugs? anticholinergic
The 2 types of receptors in the PANS are muscarinic, nicotinic
drugs that imitate(SANS+) epinephrine are known as ? sympathomimetic or adrenergic drugs
drugs that block or inhibit epinephrine (SANS-)are known as sympatholytic or antiadrenergic drugs
what are the 2 types of receptors for the SANS alpha and beta
Beta receptors of the SANS divide into 2 subclasses, what are they and what do they effect? Beta 1 = heart, Beta 2= lungs and other tissues
Which receptor of the SANS is involved in the contraction of smooth muscle vasoconstriction? Alpha
Which receptor of the SANS inhibits contraction, causing vasodialation? Beta
In the blood vessels both alpha and beta receptors are present, however which receptors predominates? Alpha
Which receptor of the SANS would you use to stimulate lower blood pressure beta 1
which receptor of the SANS would you use to stimulate higher blood pressure? beta 1, because a positive effect can increase the heart rate and a negative will decrease the heart rate.
Beta stimulation in the lungs results in? Bronchodialation
Beta stimulation in the lungs results in? Bronchodialation
A Cholinergic drug acts like acetlycholine (PANS)what are the general adverse effect of these drugs? SLUD (salivation, lacrimation, urination, defacation)
A Cholinergic drug acts like acetlycholine (PANS)what are the general adverse effect of these drugs? SLUD (salivation, lacrimation, urination, defacation)
If you needed to dry someone up name one drug you could give. Atropine
If you needed to dry someone up name one drug you could give. Atropine
For someone who had xerostomia or urinary retention what class of drug would you give? Cholinergic - Xerostomia ie saligen
For someone who had xerostomia or urinary retention what class of drug would you give? Cholinergic - Xerostomia ie saligen
A patient is going in for surgery and the surgeon wants to decrease salivary flow, urine flow etc...what class of drug does he/she give? Anticholinergic such as Atropine
Scopolamine is a drug like atropine used to treat travel sickness (vomiting) what are the main side effect? sedation, xerostomia and xeropathalmia (or dry eyes)
