Günümüzde kullanımları daha kontrollü olarak hala devam etmektedir. Ancak yan etkileri ve bağımlılık potansiyelleri nedeniyle hastaların izlenmesi gerekmektedir. Araştırmacılar tarafından, insan vücudunda doğal olarak sentezlenen ve opioid benzeri etkilere yol açan endojen opioid peptidleri bulunmuştur. Bu peptidlerin sentetik analogları da sentezlenmektedir. Bu bileşikler kimyasal yapılarından dolayı hidrofiliktir, yük taşırlar ve oral olarak uygulanmaları kısıtlıdır. Bu nedenle formülasyon için farklı yaklaşımlar geliştirilmiştir. Peptid tabanlı hidrojel sentezlenmesi ve bileşiğin hidrojele konjuge edilmesi, peptidin kumarinik asit temelli siklik bir ön ilaca dönüştürülmesi yaklaşımları stabil olmayan opioid peptidleri enzimatik parçalanmadan korur. Peptidin bir nanopartiküle yüklenmesi ve lipozomal nanotaşıyıcıların kullanılmasında nanoteknolojiden yararlanılmıştır. Multiveziküler lipozomlar (DepoFoam) kullanılarak cerrahi sonrası ağrı yönetiminde peptid temelli ilaç uygulanması mümkündür. Opioid peptidler, tedavide faydalanılabilecek birçok endikasyona sahiptir. Peptidlerin formülasyonunda çok çeşitli teknolojiler kullanılmaktadır ve bu çalışmalardan umut verici sonuçlar elde edilmiştir.","PeriodicalId":39138,"journal":{"name":"Hacettepe University Journal of the Faculty of Pharmacy","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73816330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although several studies have demonstrated its protective effects on the kidney, the FDA warns about the risk of DAPA-induced nephrotoxicity. SGLT2 inhibitors may induce oxidative stress and inflammation in the kidney due to their mechanism of action. In the present study, it was aimed to clarify the molecular effects of DAPA on the kidney. Streptozotocin (STZ)-induced diabetes was initiated by single injection of STZ (35 mg/kg b.w.) after a two-week high-fat diet in male rats. Diabetic rats were administered with DAPA at 10 mg/kg b.w., by oral gavage for 28 days. The oxidative stress, inflammation and apoptosis induction potentials of DAPA were evaluated in kidney homogenates. The morphological changes and apoptosis were investigated by histological examinations. It was observed that DAPA treatment reduced oxidative parameters. The inflammatory mediators increased in diabetic control group, however, this increase was slightly inhibited by DAPA treatment. According to the histological examinations, DAPA ameliorated the diabetes-induced changes and apoptosis. As a result, DAPA showed a protective effect on the kidney by alleviating oxidative stress and inhibiting inflammation and apoptosis. However, further studies are needed to determine the long-term effects of DAPA on the kidney in diabetics by focusing on different mechanisms and individual differences.","PeriodicalId":39138,"journal":{"name":"Hacettepe University Journal of the Faculty of Pharmacy","volume":"225 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83126307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There are several outbreaks of this disease, but diabetic foot ulcer is a dreadful situation imparting harsh skin ailments to an individual’s feet. The etiology of these ulcers includes high glucose levels, improper foot hygiene, etc. The pathophysiology of diabetic foot ulcers involves oxidative stress to the nerve tissues and other complications leading to loss of sensation in the patient’s feet along with skin dryness. Many times, diabetes remains undiagnosed but the foot ulcers can be evaluated by the latest electro-diagnostic, radiological, or vascular studies. Once identified, they can be treated with several topical antibiotics and certain foot assistance methods.
