(OT), ]home ]health ]services, ]etc. ]Prescriptive ]authority ]encompasses ]more ]than ]writing ]a ]prescri

(Mitchell ]& ]Oliphant, ]2016). ]Most ]patients ]receiving ]a ]prescription ]are ]taking ]other ]medications,
]whether ]prescription ]or ]over-the-
counter. ]Appropriate ]selection, ]dosing, ]and ]duration ]of ]pharmaceutical ]agents ]are ]key ]to ]maximi
zing ]outcomes ]and ]minimizing ]adverse ]effects

Rational ]drug ]selection ]requires ]a ]logical ]approach ]that ]includes ]the ]formulation ]of ]a ]diagnosis ]b

Considerations ]include: ]Cost, ]guidelines, ]availability, ]interactions, ]side ]effects, ]allergies, ]hepatic/

Beer's ]Criteria ]- ]correct ]answer: ]identifies ]drugs ]with ]a ]high ]likelihood ]of ]causing ]adverse ]effects ]
in ]older ]adults. ]Accordingly, ]drugs ]on ]this ]list ]should ]generally ]be ]avoided ]in ]adults ]older ]than ]65
]years ]except ]when ]the ]benefits ]are ]significantly ]greater ]than ]the ]risks.
Pharmacodynamics ]- ]correct ]answer: ]the ]study ]of ]the ]biochemical ]and ]physiologic ]effects ]of ]dru
gs ]on ]the ]body ]and ]the ]molecular ]mechanisms ]by ]which ]those ]effects ]are ]produced
Pharmacokinetics ]- ]correct ]answer: ]the ]study ]of ]drug ]movement ]throughout ]the ]body

. ]The ]purpose ]of ]this ]is ]to ]combine ]the ]sciences ]of ]genomics ]and ]pharmacology ]to ]provide ]indivi
dualized, ]targeted, ]safe ]drug ]therapies ]to ]patients
CYP450 ]inducers ]- ]correct ]answer: ]Inducers ]are ]xenobiotics ]
(medications ]and ]environmental ]agents) ]that ]elevate ]CYP450 ]enzyme ]activity ]by ]increasing ]enzy
me ]synthesis. ]This ]action ]leads ]to ]additional ]sites ]available ]for ]biotransformation. ]The ]increased ]
number ]of ]sites ]enhances ]medication ]metabolism, ]decreasing ]the ]concentration ]of ]the ]"parent ]
drug" ]while ]increasing ]metabolite ]production.
Inducers ]= ]Increase ]medication ]metabolism ]
(Carbamazepine, ]Rifampin, ]Alcohol, ]Phenytoin, ]Griseofulvin, ]Phenobarbital, ]Sulfonylureas)
CYP450 ]inhibitors ]- ]correct ]answer: ]Inhibitors ]are ]medications ]that ]inhibit ]the ]metabolic ]activity ]
of ]one ]or ]more ]of ]the ]CYP450 ]enzymes. ]Medications ]that ]inhibit ]an ]enzyme ]potentially ]slows ]th
at ]enzyme's ]activity ]or ]blocks ]the ]activity ]required ]for ]the ]metabolism ]of ]other ]medications, ]the
reby ]increasing ]the ]levels ]of ]medications ]dependent ]on ]that ]particular ]enzyme ]for ]biotransform
ation. ]Inhibitors ]= ]decrease ]medication ]metabolism ]
(Valproate, ]Isoniazid, ]Sulfonamides, ]Amiodarone, ]Chloramphenicol, ]Ketoconazole, ]Grapefruit ]Jui
ce, ]Quinidine)
cultural ]influences ]in ]prescribing ]- ]correct ]answer: ]The ]greatest ]concern ]surrounding ]race-
based ]therapy ]has ]to ]do ]with ]genetic ]variability. ]We ]know ]there ]is ]great ]diversity ]within ]and ]am
ong ]racial ]groups; ]therefore, ]a ]"one ]fits ]all" ]approach ]based ]on ]race ]is ]unwise. ]Still, ]we ]can ]use ]k
nown ]associations ]to ]guide ]choices. ]For ]example, ]differences ]in ]metabolism ]between ]people ]wit
h ]East ]Asian ]and ]European ]heritage ]are ]common. ]The ]provider ]can ]use ]this ]knowledge ]to ]guide ]i
nitial ]dosing ]
(with ]adjustment, ]as ]indicated ]based ]on ]response) ]if ]genetic ]testing ]is ]not ]feasible ]or ]warranted
Polypharmacy: ]Definition, ]challenges, ]and ]outcomes ]- ]correct ]answer: ]treatment ]with ]multiple ]d
rugs
, greatly ]increases ]the ]risk ]for ]interactions. ]Some ]of ]these ]interactions ]are ]negligible, ]but ]some ]ca
n ]have ]life-
threatening ]consequences. ]It ]is ]of ]crucial ]importance ]to ]ask ]the ]patient ]about ]all ]current ]drugs, ]i
ncluding ]over-the-counter ]
(OTC) ]medications ]and ]other ]herbal ]preparations. ]Many ]patients ]do ]not ]consider ]OTC ]or ]alterna
tive ]pharmaceuticals ]as ]"medications" ]and ]may ]not ]mention ]them ]unless ]you ]ask ]specifically.
Acute ]Pain ]Management ]- ]correct ]answer: ]

(DEA) ]coordinates ]with ]local, ]state, ]and ]federal ]agents ]to ]reduce ]illicit ]drug ]use. ]The ]DEA ]enacte
d ]the ]Controlled ]Substances ]Act ]
(CSA) ]in ]1970 ]to ]regulate ]drugs ]and ]other ]substances ]based ]on ]their ]potential ]for ]abuse ]and ]dep
