elderly (65 and older), prescriber ultimately decides
What is the CYP450 (cytochrome P450) --SOLUTION--
liver enzyme system where medications are
metabolized, can either be inducers or inhibitors and
create drug-drug interactions
CYP450 inducers --SOLUTION-- Speed up metabolism
of drugs (drug is cleared faster), drug has lesser
effect (decrease blood levels of drug), elevate
CYP450 enzymes
CYP450 inducers pneumonic --SOLUTION-- "Bullshit
Crap GPS INDUCES rage"
CYP450 inducer drug names --SOLUTION--
Barbituates, St John wort, Carbamazepine, rifampin,
alcohol, phenytoin, griseofulvin, phenobarbital,
sulfonylureas
,CYP450 inhibitors --SOLUTION-- inhibit metabolism,
increase blood levels of medications
CYP450 pneumonic --SOLUTION-- "VISA credit card debt
INHIBITS spending on designers like CK to look GQ"
CYP450 inhibitors drug names --SOLUTION-- Valproate,
isoniazid, sulfonamides, amiodarone, chloramphenicol,
ketoconazole, grapefruit juice, quinidine

Schedule IV
Not always necessary to have a prescription
Loperamide, diphenoxylate and cough medicine with
less than 200mg/100 ml pregabalin --SOLUTION--
Schedule V

for human testing --SOLUTION-- Preclinical research
Initial clinical safety studies in humans. May be as few
as 10 subjects, often healthy volunteers --SOLUTION-
- Phase I
The study drug or treatment is given to a larger group
of people (100-300) to see if it is effective and to
further evaluate its safety --SOLUTION-- Phase II
The study drug or treatment is given to large groups of
people (1,000-3,000) to confirm its effectiveness,
monitor side effects, compare it to commonly used
treatments, and collect information that will allow the
drug or treatment to be used safely --SOLUTION--
Phase III
A study conducted after a drug has been shown to work
and has been granted a license (post-marketing
surveillance study) --SOLUTION-- Phase IV
Drugs that stimulate and mimic the actions of the
sympathetic nervous system. Also called
sympathomimetics. --SOLUTION-- Adrenergic agonists
Decrease sympathetic impulses from the CNS to the
heart and arterioles, causing vasodilation
, Lowers blood pressure, diuretic may be needed
Clonodine, Methyldopa, Guanabenz
SE: dry mouth, urinary retention, weight gain etc. -
Answer>> alpha 2 agonists
A drug that blocks the actions of the sympathetic
nervous system. --SOLUTION-- Adrenergic Antagonist
Decreases arterial and venous vasoconstriction
Decreases blood pressure, helps relieve bph, Diuretic
may be needed
-osin --SOLUTION-- Alpha 1 Antagonist
drugs that block beta-adrenergic receptors; may be
nonselective or selective; also called beta blockers -
Answer>> Beta adrenergic antagonists
Effects heart muscle, blocks receptors in SA node to
decrease hr, decrease contractility
Reduces bp, reduces arrethymias, decreases angina
incidences
Metoprolol --SOLUTION-- Beta 1 Antagonist
Lowers bp
Effects lungs, bronchial constriction, avoid in asthma
patients
Propranolol --SOLUTION-- Beta 2 antagonist
do not take with acetaminophin or warfarin --SOLUTION--
Propranolol Interactions
