I-Pravastatin - Ukusetshenziswa, Isilinganiso, Imiphumela Engemihle Nokunye

Isingeniso: Iyini i-Pravastatin?

I-Pravastatin umuthi ongowesigaba semithi eyaziwa ngokuthi ama-statin, asetshenziswa kakhulu ukwehlisa amazinga e-cholesterol egazini. Ngokuvamile inikezwa ukusiza ukunciphisa ingozi yesifo senhliziyo, ukuhlaselwa yinhliziyo, kanye nesifo sohlangothi ngokulawula amazinga e-cholesterol. I-Pravastatin isebenza ngokuvimbela i-enzyme ehilelekile ekukhiqizweni kwe-cholesterol esibindini, okuholela emazingeni aphansi e-cholesterol ye-low-density lipoprotein (LDL), evame ukubizwa ngokuthi i-cholesterol "embi".

Ukusetshenziswa kwe-Pravastatin

I-Pravastatin ivunyelwe ukusetshenziswa kwezokwelapha eziningana, okuhlanganisa:

• I-Hyperlipidemia: Isetshenziselwa ukwelapha amazinga aphezulu e-cholesterol, ikakhulukazi i-LDL cholesterol ephezulu.
• Ukuvimbela Izifo Zenhliziyo: I-Pravastatin inqunyelwe ukunciphisa ingozi yezehlakalo zenhliziyo ezigulini ezinomlando wesifo senhliziyo noma labo abasengozini enkulu.
• I-Family Hypercholesterolemia: Kusebenza kahle ekuphatheni amazinga e-cholesterol kubantu abanalesi simo sofuzo esibangela i-cholesterol ephezulu.
• Ukuhlaselwa yinhliziyo ngemva kokuhlaselwa yinhliziyo: I-Pravastatin ingasetshenziswa ngemva kokuhlaselwa yinhliziyo ukunciphisa ingozi yezinkinga zenhliziyo ezengeziwe. Ukukhetha i-statin kanye nomthamo kuncike empilweni yakho iyonke, ubudala, kanye nokubekezelela kwakho. Udokotela wakho uzonquma ukuqina kwe-statin okufanele ngemva kokuhlaselwa yinhliziyo.

Isebenza Kanjani I-Pravastatin?

I-Pravastatin isebenza ngokuvimbela isenzo se-enzyme ebizwa ngokuthi i-HMG-CoA reductase, edlala indima ebalulekile ekukhiqizweni kwe-cholesterol esibindini. Ngokuvimbela le enzyme, i-pravastatin yehlisa ukukhiqizwa kwe-cholesterol iyonke, okuholela ekwehleni kwamazinga e-LDL cholesterol egazini. Lokhu kusiza ukuvimbela ukunqwabelana kwe-plaque emithanjeni yegazi, ngaleyo ndlela kunciphisa ingozi yesifo senhliziyo nesifo sohlangothi.

Isilinganiso nokuphathwa

Umthamo ojwayelekile we-pravastatin uyahlukahluka kuye ngesimo somuntu kanye nendlela asabela ngayo ekwelashweni.

Abantu abadala:

Umthamo ojwayelekile wokuqala u-10 kuya ku-20 mg othathwa kanye ngosuku, okungcono kusihlwa. Umthamo ungalungiswa ngokusekelwe emazingeni e-cholesterol kanye nokubekezelelana kwayo, ngomthamo omkhulu ongu-80 mg ngosuku.

Iziguli Zezingane:

Ezinganeni ezineminyaka engu-8 nangaphezulu, umthamo wokuqala ojwayelekile ngu-10 mg kanye ngosuku, kanti umthamo omkhulu ngu-20 mg ngosuku.

I-Pravastatin itholakala ngesimo samaphilisi futhi kufanele ithathwe ngomlomo nokudla noma ngaphandle kokudla. Kubalulekile ukulandela umthamo kanye neshejuli enqunyiwe enikezwa uchwepheshe wezempilo.

Imiphumela Engemihle Ye-Pravastatin

Njengayo yonke imithi, i-pravastatin ingabangela imiphumela emibi.

Imiphumela emibi evamile ihlanganisa:

• bekhanda
• I-nausea
• Uhudo
• Ubuhlungu bemisipha noma ubuthakathaka
• Ukukhathala

Imiphumela emibi kakhulu, nakuba ingavamile, ingase ihlanganise:

• Izinkinga zesibindi (eziboniswa ukuphuzi kwesikhumba noma amehlo)
• Izinkinga ezinkulu zemisipha, njenge-rhabdomyolysis, azivamile kakhulu kodwa zingaba zimbi kakhulu. Ukubikwa kusenesikhathi kobuhlungu bemisipha, ukuthamba, umchamo omnyama, noma ubuthakathaka obungavamile kusiza ukuvimbela izinkinga.
• Ukungezwani komzimba (ukuqubuka, ukulunywa, ukuvuvukala)

Iziguli kufanele zibike noma yiziphi izimpawu ezingavamile kumhlinzeki wazo wezempilo ngokushesha.

Ukusebenzisana kwezidakamizwa

I-Pravastatin ingasebenzisana nemithi eminingana kanye nezinto ezisetshenziswayo, okungandisa ingozi yemiphumela emibi noma kunciphise ukusebenza kwayo. Ukusebenzisana okukhulu kwemithi kufaka phakathi:

• Amanye ama-statin: Ukusebenzisa ama-statin amaningi kungandisa ingozi yemiphumela emibi ehlobene nemisipha.
• Ama-Fibrates: Ukuhlanganisa i-pravastatin nama-fibrate athile kungandisa ingozi yezinkinga zemisipha. I-Gemfibrozil inengozi ephezulu yokubangela imiphumela emibi ehlobene nemisipha uma isetshenziswa nama-statin. I-Fenofibrate ngokuvamile ibhekwa njengephephile kodwa kufanele isetshenziswe ngokuqapha.
• Ama-antibiotic kanye nemithi yokulwa nesikhunta: I-Pravastatin ngokuvamile ayinazo izindlela eziningi zokwelapha izidakamizwa kunezinye izidakamizwa ngoba ayicutshungulwa kakhulu ngama-enzyme e-CYP450. Kodwa-ke, amanye ama-antibiotic (njenge-erythromycin) noma imithi elwa namagciwane (njenge-ketoconazole) angandisa ingozi yemiphumela emibi uma ithathwa kanye ne-pravastatin. Udokotela wakho angase alungise umthamo wakho noma akuqaphe eduze uma udinga le mithi.

Iziguli kufanele zazise umhlinzeki wazo wezempilo ngayo yonke imithi eziyisebenzisayo, okuhlanganisa nemithi ethengiswa ngaphandle kwemithi kadokotela kanye nezithasiselo.

Izinzuzo ze-Pravastatin

I-Pravastatin inezinzuzo eziningana zezokwelapha nezisebenzayo, okuhlanganisa:

• Ukulawulwa Okuphumelelayo Kwe-Cholesterol: Yehlisa kakhulu amazinga e-cholesterol e-LDL, okubangela impilo yenhliziyo engcono.
• Ukunciphisa Ingozi Yenhliziyo: Kuyasiza ekunciphiseni ingozi yokuhlaselwa yinhliziyo kanye nokushaya kwenhliziyo kubantu abasengozini.
• Okubekezelelwe Kahle: Iziguli eziningi zibekezelela kahle i-pravastatin, kanye nemiphumela emibi elawulekayo.
• Umthamo Wansuku zonke: Ukulula komthamo owodwa wansuku zonke kuthuthukisa ukunamathela ekwelashweni.

Izimo zokuphikisana ne-Pravastatin
