Ntshav qab zib thiab kev rog tau dhau los ua ob txoj kev cov nyom loj hauv ntiaj teb kev noj qab haus huv hauv ntiaj teb. Raws li lub Koom Haum Ntiaj Teb Kev Noj Qab Haus Huv (Leej twg), tus naj npawb ntawm cov neeg mob ntshav qab zib muaj ntau dua 500 lab, thiab tus naj npawb ntawm cov neeg rog tau dhau 1 txhiab tus neeg. Kev Kho Mob Ib txwm muaj muaj kev txwv ntawm cov ntshav plab zom mov thiab kev tswj hwm ntshav, thiab kev tsim hluav taws xob tau ua kom nrawm nrawm rau cov kev cuam tshuam. Tirzepatide, raws li ib hom tshiab ntawm Dual Receptor Eponist, nrog nws cov kev ua tau zoo dua thiab tseem ceeb rau kev kho mob ntshav qab zib thiab rog. Kab lus no yuav tau txheeb xyuas tus nqi tshiab ntawmTirzepatideLos ntawm plaub qhov ntev: Tshuaj Yeeb Tshuaj, Cov Ntsiab Lus ntawm Kev Ua, Daim Ntawv Thov Kev Kho Mob, thiab Yav Tom Ntej.

Cov yam ntxwv ua tshuaj: Kev tsim kho tshiab hauv cov qauv tshuaj thiab cov kws ua tshuaj ua noj ua ke
Tus Qauv Tshuaj Txheej Txheem: Tsim Tsim Tsim ntawm 39 amino acids
Tirzepatide yog ib qho synthesly ua 39 - amino {} kua qaub linear peptide. Nws cov qauv yog engineered raws cov kab ke ntawm cov piam thaj qabzoo-nyob hauv insulinottropic polypepropic polypeptide (gip). Cov qauv tseem ceeb muaj xws li:
Tsis - ntuj amino acid hloov kho:Qhia Amino iSobutyric acid (AIB) ntawm txoj haujlwm 2 thiab 13 los txhim kho molecular ruaj khov thiab receptor binding tshwj xeeb.
C20 fatty acid saw txuas:Txuas 1,20 {{{- tert {}} gluorecanooctlamtoctanoic Linping, txoj kev sib tw ntev-saw pham acid qauv.
C -} Lub davhlau ya nyob twg:Terminate c -}}} pab pawg nrog ib pawg amide, txuas ntxiv ruaj khov lub molecular conformation.
Tus qauv no xaus nrog dual receptor agonist muaj peev xwm, thiab albumin binding,} lub neej rau 120 teev, koom nrog ib zaug ua haujlwm.
Pharmaconinetics: Ntev - ua yeeb yam thiab ruaj khov sib npaug
Kev nqus:Tom qab kev txhaj tshuaj, tirzepatide yog maj mam nqus tau los ntawm cov lymphatic system, nrog lub sijhawm siab ntev (tmax) ntawm 48-72 teev.
Faib: Highly bound to plasma albumin (>99%), nrog cov khoom xa tawm (VD) ntawm 11.7 L.
Metabolism:Feem ntau degraded los ntawm peptide enzymes, tsis yog nyob ntawm Cytochrome P450 enzyme system, txo txoj kev pheej hmoo ntawm cov kev pheej hmoo ntawm cov tshuaj sib cuam tshuam.
Excretion:Ua kom tiav raws li cov metabolites los ntawm ob lub raum, tsis muaj kev hloov kho kom haum rau cov neeg mob uas tsis muaj kev pheej hmoo (tab sis vigilance rau lub cev muaj hmoo tsis txaus ntseeg.

Mechanism ntawm Kev Ua: Synergistic Kev Cai los ntawm GLP-1 thiab GIP Receptors
Ua kom muaj ntawm GLP-1 tus receptor: Dual kev cai ntawm cov ntshav ntshav qab zib thiab lub cev hnyav
GLP-1 cov receptor ua kom zoo dua cov metabolism hauv qab no txoj hauv kev:
Txhim Kho Insulin Incallion: qab zib {}
Glucagon Inhibition: Txo cov zais cia ntawm glucagon los ntawm cov hlwb pancreatic, ntxiv rov qab cov ntshav qab zib ntxiv.
Ncua lub plab zom mov: qeeb ntawm lub plab zom mov, ua kom muaj kev vam meej satiety, thiab txo cov zaub mov noj kom tsawg.
Appetite Cenation kev cai tswj: Ua raws li lub chaw pub mis nyob rau hauv hypothalamus, interhiting kev tshaib plab, thiab txhawb kom yuag poob.
Ua kom muaj kev ua haujlwm ntawm GIP: Kev ua kom zoo ntawm insulin rhiab rhiab thiab cov roj metabolism thiab rog rog
Kev ua kom muaj zog ntawm GIP receptors pab cov teebmeem ntawm GLP-1 los ntawm cov txheej txheem hauv qab no:
Txhim kho Insulin Daim Ntawv Sau Tseg: Stimulates Beta hlwb hauv Synergy nrog GLP-1, tshwj xeeb tshaj yog thaum hypoglycemia.
Txhim kho cov insulin rhiab: Ua rau cov nqaij adpose, txhawb kev rog, tso cov roj ntsha tsis zoo, thiab txhim kho insulin rhiab.
Kev tswj cov rog: inhibits daim siab rog saftthesis, txo cov roj ntsha visceral, thiab txhim kho Lipid metabolism.
Qhov zoo dual agonist kom zoo dua: syergistic nyhuv ntawm 1 + 1> 2
Tirzepatide cov khoom ua pov thawj asymmetry nyob rau hauv nws cov kev ua kom muaj GLP-1 thiab GIP RECEPTORS:
Lub affinity ntawm GIP receptors yog siab dua: nws affinity rau ntuj gip yog tsib zaug ntawm GLP-1, txhim kho insulin tso zais pa thiab kev tswj hwm ntawm cov roj me metabolism.
Lub GLP - 1 receptor yog qhov ua kom zoo dua qub: nws feem ntau ua kom tau txais kev kho mob kom zoo nkauj, txo cov kev ua haujlwm tau txais txiaj ntsig zoo los ntawm kev ua haujlwm zoo nkauj, thiab sijhawm ntev lub sijhawm.
Qeb ntawm Adiponectin yog nce: nws tseem ceeb nce lub zais ntawm adiponectin (ib qho insulin {}}}}}} ecsulin tsis kam thiab arteriosclerosis.
Qhov no dual agonist mechanism ua rau kev nthuav tawm cov kev tswj hwm cov ntshav qab zib thiab cov kev tswj kom muaj kev ntxhov siab ib leeg.
Kev xam pom yav tom ntej: kev nthuav tawm los ntawm cov ntshav qab zib rau cov mob metabolic
Qhia Qhia nthuav dav: Tsis {-}}}}}}}}} ishment rog rog (Nash) thiab Chronic Mob Kab Mob (CKD)
Kev Kho Mob Nash: Tirzepatide qhia cov peev xwm hauv kev txhim kho lub siab mob ntsws fibrosis thiab muaj kev ua kom muaj zog nyob hauv Nash cov neeg mob thiab tam sim no nyob rau theem III chaw kuaj mob.
CKD kev kho mob: hauv CKD cov neeg mob uas muaj cov kev pheej hmoo ntawm cov proteinuria thiab tsis zoo rau kev xaiv ua tshiab rau CKD.
Kev Kho Mob: Synergistic Daim Ntawv Thov nrog cov tshuaj insulin lossis lwm yam kev mob siab ntsws
Basal insulin kev sib xyaw ua ke: kev sib xyaw nrog cov tshuaj tiv thaiv kab mob ntshav qab zib tuaj yeem ua kom txo cov ntshav qab zib ntshav qab zib thiab txo cov insulin ntau thiab kev pheej hmoo ntawm hypoglycemia.
SLGLT-2 inhibitor kev cai: kev sib xyaw nrog SGLT-2 Inhibitors tuaj yeem txhim kho cov neeg mob plawv thiab cov txiaj ntsig rov qab, tshwj xeeb tshaj yog rau cov neeg mob nrog cov kab mob plawv lossis ckd.
Qhov ncauj tsim kev tsim kho: Ua txhaum los ntawm cov kev txwv ntawm kev txhaj tshuaj
Qhov ncauj Tirzepatide: tam sim no nyob rau hauv kev txhim kho, los ntawm kev nkag mus txhim kho qhov ncauj siv tshuab los txhim kho qhov ncauj ntawm qhov ncauj, yog tias ua tiav, nws yuav txhim kho tus neeg mob ua raws.
Ntev -}} kev ua tau zoo thiab kev nyab xeeb: Kev saib xyuas thiab ua kom zoo dua qub
Ntev -} sau cov ntaub ntawv sau: Ntxiv cov ntaub ntawv sau ntawm kev ua tau zoo thiab kev nyab xeeb ntawm Tirzepatide tshaj 5 xyoos kev cuam tshuam ntawm cov qog, pob txha metabolism, thiab lwm yam.
Cov tshuaj kho mob ib leeg rau cov neeg: tshawb txog cov tshuaj kho mob raws cov cai raws li cov neeg genotypes, phenotypes, lossis biomarkers kom ua kom cov txiaj ntsig kho kom tshwm sim.
Kev Nyab Xeeb thiab Ua Rau Muaj: Feem ntau cov hnyuv siab, feem ntau tswj tau
Cov Kev Ruaj Ntseg Sib Xws: Feem Ntau Cov Txheej Txheem
Xeev siab: tshwm sim nyob rau hauv txog 30% -40% ntawm cov neeg muaj mob, feem ntau me me mus rau nruab nrab, thiab maj mam sib npaug, thiab maj mam sib npaug, thiab maj mam sib npaug, thiab maj mam sib npaug, thiab maj mam sib npaug, thiab maj mam sib npaug, thiab maj mam sib npaug, thiab maj mam sib raws sijhawm.
Zawv plab: tshwm sim li 20% -30%, feem ntau thaum lub sij hawm xaiv kev khiav dim.
Ntuav: tshwm sim li ntawm 10% -15%, ntsig txog xeev siab.
Cem quav: tshwm sim li 10%, tej zaum tau vim muaj kev ncua plab.
Cov nyom tshwm sim loj: tsawg tsawg tab sis Well Wranture Vigilance
Pancuitis: tshwm sim hauv<0.5%, requires monitoring for symptoms such as abdominal pain and vomiting.
Thyroid C - Cov qog cell: cov kev sim tsiaj qhia kev pheej hmoo, tab sis tsis muaj pov thawj hauv tib neeg. Zam txhob ua rau cov neeg mob nrog keeb kwm lossis tsev neeg keeb kwm ntawm kev sib tham thyroid carcinoma.
Hypoglycemia: tsawg hypoglycemia tus nqi qis (<2%) with monotherapy, but need to be vigilant when combined with insulin or sulfonylureas.
Cov tshuaj rau cov neeg tshwj xeeb
Cov tsis muaj npe tsis txaus: Tsis muaj kev hloov kho cov hmoov av (tab sis saib xyuas kev pheej hmoo ntawm lub cev qhuav dej (tshwj xeeb yog thaum ua kom ntuav lossis raws plab).
Mob siab tsis txaus: Tsis muaj kev hloov kho cov neeg mob me uas muaj mob me me mus rau lub siab tsis txaus, tab sis kev ceev faj rau cov neeg mob uas tsis txaus siab.
Cov neeg laus: Tsis tau hloov kho cov kev yuav tsum tau kho, tab sis ceeb toom rau cov kev pheej hmoo ntawm hypoglycemia thiab lub cev qhuav dej.
Cov menyuam yaus thiab cov tub ntxhais hluas: kev nyab xeeb thiab kev ua tau zoo tsis tau tsim, tsis pom zoo rau cov neeg mob hnub nyoog qis dua 18 xyoo.
