QUESTION
Leukotrienel modifiers

Answer:
Leukotrienel receptorl antagoinistsl (LTRAs)l andl 5l lipoxygenasael pathwayl inhibitorsl
developedl basedl onl thel theoryl thatl cysteinyll leukotrienesl playl al significantl rolel inl thel
chronicl inflammationl associatedl withl asthmal andl allergy
->l Thisl causesl airwayl ededmal smoothl musclel constriction,l andl cellularl changesl
associatedl withl thel inflammatoryl process
->Originallyl al lotl ofl excitementl whenl thesel camel tol thel marketl butl nowl actuallyl onlyl
typicallyl usedl asl secondl line
->Canl bel orall whichl mightl helpl withl compliance



QUESTION
Leukotrienel modifiersl PK

Answer:
-leukotienel receptorl antagonistsl =l zafirlukast,l montelukast
-5l lipoxygenasel pathwayl inhibitors=l zileuton
-typicallyl welll absorbed,l 3-5l hrl halfl lie
-extensivel hepaticl metabolism,l cautionl forl liverl disease



QUESTION
Leukotrienel modifersl precautions

Answer:

,-avoidl zileutonl inl severel liverl diease
***dol notl usel forl primaryl treatmentl ofl anl acutel asthmal attackl (longerl terml affects)
-chewablel montelukastl containsl phenylalanine-l don'tl takel ifl youl havel PKU
-cautionl ifl systemicl corticosteroidl dosel isl reducedl orl substitutedl canl leadl tol
eosinophilia,l vascularl rash,l worseningl pulm,l cardiacl complicationsl andl neuropathy
-reportsl ofl neuropsychiatricl events
Zileuton=l pregl c
LTRASl generally=l pregl b
Zafirlukastl goodl forl kidsl agel 5+,l Montelukastl >l 12l m
Leukotrinel modifiersl s/e
-zileutonl rare=l hepaticl injury
Drugl interactions:l increasel theophyllinel levelsl sol mustl decreasel theophyllinel dose
Canl increasel PTl withl Warfarin



QUESTION
LTRA'sl clinicall usel andl ptl education

Answer:
-treatmentl ofl CHRONICl ASTHMA
-montelukast=l preventl ofl exercisel inducedl bronchoconstrictionl inl agel >15,l allergicl
rhinitisl >6l months
-mustl bel takenl dailyl evenl ifl symptoml free-l notl forl acutel episodes,l mustl continuel

QUESTION
Inhaledl corticosteroidsl (ICS)

Answer:
-beclomethasone,l triamcinolone,l budesonidel (Pulmicort),l fluticasonel (Flovent)
-PD:l suppressesl airwayl inflammationl byl activatingl anti-inflaml genes,l switchingl offl
inflammatoryl genel expressionl andl inhibitingl inflammatoryl cells
->l reductionl inl thel severityl ofl asthmal symptoms,l increasedl peakl flowl readings,l andl
decreasedl airwayl hyperl responsiveness
-inl general,l safel andl welll toleratedl forl childrenl andl adults
-corticosteroidsl canl alsol bel usedl intranasallyl forl allergicl rhinitis



QUESTION

,Inhaledl corticosteroidsl PK

Answer:
-onlyl 10-30%l systemicallyl absorbed,l spacersl increasel overalll absorption
-asthma=l preferredl longl terml controll medicationsl forl managingl thel inflammaotryl processl
withl asthma
-willl startl onl alll patientsl withl mildl persistentl asthmal orl wrose
Or
-allergicl rhinitis=l nasall cortico

Answer:
-***notl indicatedl alonel forl acutel asthmal attackl orl usel forl reliefl ofl acutel bronchospasm
-ifl takingl withl orall steroids,l increasel riskl forl hypothalamicl pituitaryl adrenall suppressionl
(HPA)\
-avoidl inl ptsl withl Cushings
-pregl C,l budesonidel DOCl inl preg*
-**highl dosel inhaledl steroidsl inl childrenl mayl inhibitl growth
