MODULE v1
1. What vare vthe vBON vrules vand vregulations vfor vprescriptive vauthority vfor vthe
vadvance vpractice vnurse?
1. Texas vis vvery vrestricted
2. Describe vthe vpharmacokinetic vprocesses vof vabsorption, vdistribution, vmetabolism
vand velimination vand vhow vdifferences vin vthese vareas vaffect vdrug vaction.
1. Absorption
1. Drug’s vmovement vfrom vthe vsite vof vadministration vinto vthe vblood.
2. Distribution
1. Drug’s vmovement vfrom vthe vblood vinto vthe vinterstitial vspace
vof vtissues vand vfrom vthere vinto vcells.
3. Metabolism
1. Biotransformation vis vthe venzymatically vmediated valteration vof
vdrug vstructure.
4. Elimination
1. Combination vof vmetabolism vand vexcretion
3. Compare vand vcontrast vpharmacokinetics vand vpharmacodynamics vof
vspecial vpopulations—pediatrics, volder vadults vand vthose vthat vare vpregnant.
1. Pediatrics—they vhave vorgan vimmaturity, velderly—they vhave vorgan
vdegeneration, vloss vof vnephrons, vexcretion vof vdrug vis vdecreased vand vyou vhave
vto vgive vthis vpopulation va vlower vdose vof vmedication. vMedication vcan vpass
vthrough vmilk vof vlactating vfemales.
4. Analyze va vdrug vinteraction vto vdetermine van vappropriate vcourse vof vaction.
1. Basic vmechanism vof vdrug-drug vinteractions vthrough vpharmacokinetic
vinteractions vare valtered vabsorption, valtered vdistribution, valtered vmetabolism,
vand valtered vrenal vexcretion.
5. Identify vmedications vwith va vnarrow vtherapeutic vindex vrequiring vdrug
vlevel vmonitoring.
1.
6. Discuss vthe veffect vof vionization vand vpH von vabsorption.
1. Drugs vthat vare vweak vacids vare vbest vabsorbed vin vacidic venvironments. vAcidic
vdrugs vaccumulate von vthe valkaline vside, vbasic vdrugs vaccumulate von vthe vacidic
vside vknown vas vion vtrapping. vIonization vof vthe vdrugs vis vpH vdependent, vwhen vthe
vpH vand vthe vfluid von vone vside vof vthe vmembrane vdiffers vfrom vthe vpH von vthe
vother vside, vdrug vmolecules vtend vto vaccumulate von vthe vside vwhere vthe vpH vmost
vfavors vionization.
7. Discuss vfactors vaffecting vdrug vdistribution.
1. Competition vfor vprotein vbinding vand valteration vof vextracellular vpH
8. Discuss vbarriers vaffecting vdrug vdistribution—such vas vplacental vmembrane,
vblood vbrain vbarrier vand vvolume vof vdistribution.
1. Placental vmembrane: vdrugs vare veasily vpassed vthrough vthe vplacental vmembrance
2. Blood vbrain vbarrier: vthe vPGP vpumps vdrugs vback vinto vthe vblood vand vthereby
vlimits vtheir vaccess vto vthe vbrain.
3. Volume vof vdistribution:
,9. Discuss vthe v“first-pass veffect”—what veffect vcan vthis vhave von vdistribution vof va vdrug?
1. Rapid vhepatic vinactivation vof vcertain voral vdrugs. vWhen vdrugs vare vabsorbed vby
vthe vGI vtract, vthey vare vcarried vdirectly vto vthe vliver vthrough vthe vhepatic vportal
vvein
, before ventering vthe vsystemic vcirculation. vIf vthe vcapacity vof vthe vliver vto vmetabolize
vthe vdrug vis vextremely vhigh, vthis vdrug vcan vbe vcompletely vinactivated von vits vfirst
vpass vthrough vthe vliver.
10. Discuss vthe vsignificance vof vthe vCytochrome vP450 vsystem von vmetabolism vof vdrugs.
1. It vis va vgroup vof v12 vclosely vrelated venzyme vfamilies. vCYP1, vCYP2, vCYP3
vmetabolize vdrugs. vThe vother v9 vfamilies vmetabolize vendogenous vcompounds
v(ex. vFatty vacids, vsteroids).
11. Discuss vthe vmajor vhepatotoxic vdrugs vand vpossible veffects von vdrug
vmetabolism. v1.
12. List vvarious vroutes vof vdrug velimination—review vnormal vrenal vfunction vincluding
vglomerular vfiltration, vpassive vtubular vreabsorption vand vactive vtubular vsecretion;
vdescribe vthe vimplications von vdrug vclearance vand vhow velimination vaffects
vprescribing.
1.
13. Discuss vterms vused vto vdescribe vdrug vactions-agonist, vpartial vagonist, vantagonist.
1. Agonist: vmolecules vthat vactivate vreceptors
2. Partial vagonist: vOnly vhas vmoderate vintrinsic vactivity. vMaximal veffect vthat va
vpartial vagonist vcan vproduce vis vlower vthan vthat vof va vfull vagonist.
3. Antagonist: vProduce vtheir veffects vby vpreventing vreceptor vactivation vby
vendogenous vregulatory vmolecules vand vdrugs.
14. Discuss vthe vimpact vof vfood von vdrug vabsorption, vdrug vmetabolism vand von vdrug
vtoxicity vand vaction—as vwell vas vthe vtiming vof vdrug vadministration.
LIFESPAN
1. Hepatic vmetabolism vand vGFR vincrease vduring vpregnancy, vdosages vof vsome
vdrugs vmay vneed vto vbe vincreased.
2. Rate vof valbumin vto vwater vdecreases
1. Third vtrimester: vRenal vblood vflow vis vdoubled vand vrenal vexcretion
