Wannan tsarin aikin mai karɓa da yawa yana ba shi fa'idodi na musamman a cikin asarar nauyi. Idan aka kwatanta da magungunan asarar nauyi waɗanda ke aiki akan mai karɓa guda ɗaya, Retatrutid na iya ƙarin daidaita tsarin tafiyar da rayuwa ta jiki [1] . Retatrutid yana samun asarar nauyi ta hanyar daidaita masu karɓar hormone da yawa. Ba wai kawai yana da tasiri mai mahimmanci na asarar nauyi ba amma har ma yana da ƙananan sakamako masu illa na gastrointestinal. Bugu da ƙari, idan aka kwatanta da wasu sababbin magungunan asarar nauyi, Retatrutid, a matsayin mai agonist mai karɓa sau uku, yana da tasiri mai tasiri mai karfi da kuma yawan adadin yawan jama'a.
Menene tsarin aikin Retatrutid?
Tsarin aikin Retatrutid ya samo asali ne daga tasirin tasirinsa akan masu karɓa da yawa. Da farko, tasirinsa na agonist akan mai karɓa na glucagon-kamar peptide-1 (GLP-1R) yana ƙara haɓakar insulin, yana hana ƙwayar glucagon, yana rage matakan glucose na jini, kuma a lokaci guda yana jinkirta zubar da ciki, yana ƙaruwa, kuma yana rage cin abinci [2] . Abu na biyu, tasirinsa na agonist akan mai karɓar insulinotropic polypeptide mai karɓa na glucose (GIPR) na iya haɓaka haɓakar insulin, haɓaka amfani da glucose, kuma yana da tasiri akan metabolism na mai, hana lipolysis da haɓaka haɓakar mai [2] . Bugu da ƙari, kodayake tasirin agonist na Retatrutid akan mai karɓar glucagon (GCGR) yawanci yana haɓaka glycogenolysis da gluconeogenesis a cikin hanta, haɓaka matakan glucose na jini, a ƙarƙashin aikin Retatrutid, wannan tasirin haɓakar glucose na jini yana raguwa ta sakamakon sauran masu karɓa guda biyu. A lokaci guda, yana inganta lipolysis kuma yana rage yawan kitse [2] . Wannan yanayin aiki mai yawan manufa na iya zama mafi inganci wajen magance kiba fiye da agonists masu karɓa ɗaya.
Ta hanyar kunna waɗannan masu karɓa guda uku a lokaci guda, Retatrutid na iya yin tasiri iri-iri na tsarin rayuwa da kuma haifar da tasirin warkewa akan kiba da cututtukan da ke da alaƙa. Dangane da daidaita matakan glucose na jini, saboda kunna GLP-1R da GIPR waɗanda ke haɓaka haɓakar insulin da hana ƙwayar glucagon, da kunna GCGR ta hanyar tasirin sauran masu karɓa guda biyu, Retatrutid na iya daidaita matakan glucose na jini yadda ya kamata, wanda ke da mahimmanci ga kula da nau'in ciwon sukari na 2, [1] .

Ta yaya daidai Retatrutid ke sarrafa glucose metabolism bayan kunna masu karɓa uku?
Retatrutid yana sarrafa glucose na jini ta hanyoyi da yawa, gami da kunna GLP-1 da masu karɓa na GIP, haɓaka ƙwayar insulin, hana ƙwayar glucagon, jinkirta zubar da ciki, daidaita metabolism mai, da rage matakan ANGPTL3/8. Dangane da tsarin glucose na jini, Retatrutid yana aiki akan GLP-1 da masu karɓar GIP, yana haɓaka haɓakar ƙwayoyin pancreatic β zuwa glucose, haɓakawa da sakin insulin, sa'an nan kuma haɓaka haɓakawa da amfani da glucose ta kyallen takarda, yana samun tasirin rage glucose na jini [4, 5] . (HbA1c), wanda galibi yana fa'ida daga rawar da yake takawa wajen haɓaka fitar insulin (Rosenstock J, 2023). A lokaci guda, kunna mai karɓar GLP-1 na iya hana ƙwayar glucagon ta ƙwayoyin α pancreatic, yana hana glucose jini daga girma. A cikin nazarin asibiti, an lura cewa matakan glucagon na marasa lafiya da ke amfani da Retatrutid sun ragu, wanda hakan yana taimakawa wajen tabbatar da kwanciyar hankali na glucose na jini [4, 5] . Kunna masu karɓar GLP-1 da GIP kuma na iya jinkirta adadin zubar da ciki, rage narkewar abinci da sha, da rage haɓakar hauhawar glucose na jini bayan cin abinci. Nazarin ya nuna cewa lokacin zubar da ciki na marasa lafiya da aka yi wa magani tare da Retatrutid yana tsawaitawa sosai bayan cin abinci, don haka yana rage ƙimar ƙimar glucose na jini na postprandial [4].
Tsarin metabolism na mai ta hanyar Retatrutid shima yana shafar metabolism a kaikaice. Alal misali, a cikin nazarin marasa lafiya masu kiba, an gano cewa Retatrutid na iya rage matakan triglycerides (TG), low-density lipoprotein (LDL), da ƙananan ƙananan ƙwayoyin cuta (VLDL) cholesterol [2, 6] . Wannan haɓakawa a cikin metabolism na lipid na iya kasancewa yana da alaƙa da haɓaka haɓakar insulin, ta haka yana ba da gudummawa ga sarrafa glucose na jini. Musamman, bayan magani na Retatrutid, plasma 3-hydroxybutyric acid (3-HB) yana ƙaruwa, tare da karuwa a cikin 3-hydroxybutyrylcarnitine (C 4OH), rabon acetylcarnitine zuwa carnitine kyauta (C 2/ C 0), da kuma acylcarnitine matsakaici-sarkar, yana nuna haɓakar lipolysis a cikin ƙima da haɓakar kitse.
Retatrutid kuma zai iya rage jimlar dihydroceramides (DhCers), kuma wannan canji yana hade da ingantaccen insulin hankali, rage steatosis na hanta, da kumburi na tsarin [6] .A lokaci guda, Retatrutid kuma zai iya rage ƙaddamar da hadaddun ANGPTL3 / 8 a cikin nau'in nau'in ciwon sukari na 2 na ciwon sukari, yana daidaita glucose metabolism [7] . ANGPTL3/8 shine mafi inganci mai hanawa na lipoprotein lipase (LPL), kuma matakin jininsa yana da alaƙa kai tsaye da TG da ƙananan ƙarancin lipoprotein cholesterol (LDL-C). Retatrutid yana rage matakin ANGPTL3/8, wanda zai iya daidaita glucose metabolism ta hanyar rage lipoproteins masu wadatar triglyceride [7] .
A waɗanne bangarori ne Retatrutid ke nuna tasirin sa?
Muhimman tasirin asarar nauyi:
Retatrutid ya nuna gagarumin tasirin asarar nauyi a cikin gwaje-gwajen asibiti da yawa. Alal misali, a cikin binciken asibiti wanda ya shafi manya na 338 [2] , marasa lafiya da aka bi da su tare da nau'i-nau'i daban-daban na Retatrutid sun sami asarar nauyi a cikin makonni 48. Daga cikin su, marasa lafiya a cikin rukunin kashi na 12mg suna da asarar nauyi na 24.2%, kuma yawancin marasa lafiya sun sami asarar nauyi zuwa digiri daban-daban. Misali, tsakanin marasa lafiya da ke karbar 4mg, 8mg, da 12mg allurai, 92%, 100%, da 100% na marasa lafiya sun rasa 5% ko fiye na nauyin jikinsu, bi da bi. A cikin wani binciken [8] , gwaje-gwajen da aka sarrafa guda biyu da suka shafi 353 nau'in ciwon sukari na 2 sun nuna cewa idan aka kwatanta da placebo, Retatrutid zai iya rage nauyin jikin marasa lafiya da 11.89kg kuma ya rage glycated haemoglobin (HbA1C). Bugu da ƙari, a cikin gwaji na marasa lafiya marasa ciwon sukari, Retatrutid ya haifar da asarar nauyi na 24.2% a cikin marasa lafiya, kuma 83% na marasa lafiya sun rasa 15% ko fiye na nauyin jikinsu a makonni 48. Wadannan sakamakon sun nuna cewa Retatrutid yana da babban tasiri a cikin asarar nauyi.
Jiyya na nau'in ciwon sukari na 2 :
Retatrutid kuma yana nuna wasu yuwuwar a cikin maganin nau'in ciwon sukari na 2. A wasu gwaje-gwajen asibiti, Retatrutid ya nuna raguwar haemoglobin glycated (HbA1c) da asarar nauyi mai dogaro da kashi. Alal misali, a cikin binciken daya, a cikin nau'in ciwon sukari na 2, Retatrutid ya nuna tasiri mai mahimmanci na sarrafa glucose na jini, yana rage glycated haemoglobin da 1.64% idan aka kwatanta da placebo [4, 8] . Bugu da ƙari, a cikin bazuwar, makafi biyu, placebo, da kuma aiki mai sarrafa nau'i-nau'i-nau'i-nau'i-nau'i 2 gwaji, nau'in dabba da nau'in ciwon sukari na 2 ya nuna raguwa mai yawa a cikin matakan haemoglobin glycated da asarar nauyi mai dogara da kashi bayan karbar magani na Retatrutid [4] . Ana iya danganta wannan ga cikakken tasirin maganin akan GLP-1, GCGR, da GIPR, waɗanda ke haɓaka metabolism na glucose da ma'aunin kuzari.
Inganta abubuwan haɗari na zuciya:
Retatrutid ba zai iya rage nauyin jiki kawai ba har ma yana inganta abubuwan haɗari na zuciya da jijiyoyin jini, kamar bayanin martabar jini da matakan haemoglobin glycated. Wannan yana nuna kusancin pathophysiological tsakanin kiba da cututtukan zuciya, kuma Retatrutid na iya inganta lafiyar cututtukan zuciya na marasa lafiya masu kiba ta hanyoyi da yawa. Misali, rage marasa HDL-C, apoB, da LDLP matakan na iya rage haɗarin atherosclerosis; Rage matakan haemoglobin glycated na iya inganta sarrafa glucose na jini a cikin masu ciwon sukari, don haka rage haɗarin rikice-rikice na zuciya [8-10] .
Maganin cutar hanta mai ƙiba mara-giya (NAFLD):
Retatrutid wani labari ne na peptide mai karɓar mai karɓa sau uku wanda ke hari ga mai karɓar glucagon (GCGR), mai karɓar insulinotropic polypeptide mai dogaro da glucose (GIPR), da mai karɓar glucagon-kamar peptide-1 (GLP-1R). Nazarin ya nuna cewa Retatrutid yana da damar yin maganin cututtukan hanta maras-giya. A cikin binciken daya, an gudanar da gwajin bazuwar, makafi biyu, gwajin sarrafa wuribo na tsawon makonni 48 akan mahalarta tare da cututtukan hanta mai rauni mai alaƙa da ƙwayar hanta mai abun ciki na ≥10%.
