Umsebenzi
I-Pranlukast lichiza lomlomo elichasene ne-aleji elisetyenziswa ikakhulu ukunyanga i-asthma kunye ne-rhinitis ye-alergic. Yinto ekhethiweyo ye-leukotriene receptor antagonist evimbela ngokufanelekileyo imiphumo ye-leukotrienes, ngaloo ndlela inciphisa iimpawu ezinxulumene nokungahambi kakuhle kunye ne-asthma. Le ilandelayo yimisebenzi ephambili yePranlukast:
1. Isiphumo sokuchasa ukudumba:I-Pranlukast inceda ukulawula iimpawu ze-asthma ngokuthintela iziphumo ze-leukotrienes kunye nokunciphisa impendulo yokuvuvukala kwiindlela zomoya.
2. Phucula umsebenzi wokuphefumla:Ngokunciphisa ukuxinwa kunye nokuvuvukala kweendlela zomoya, i-Pranlukast inokuphucula umsebenzi wokuphefumula wezigulane ze-asthma kunye nokunciphisa ukuvela kokuphefumla kunye nobunzima bokuphefumla.
3. Ukuphelisa iimpawu zokwaliwa:I-Pranlukast ikwasetyenziselwa ukunyanga i-rhinitis ye-allergies kwaye inokuphelisa iimpawu zokungalungelani ezifana nokuxinana kweempumlo, impumlo ephumayo, ukuthimla, njl.
4. UThintelo loHlaselo lwe-Asma:Ukusetyenziswa kwexesha elide le-Pranlukast kunokunceda ukukhusela ukuhlaselwa kwe-asthma, ngakumbi kwizigulana ezine-asthma ezibangelwa umthambo.
