Nimodipine is a prominent calcium channel blocker that must be\u0000given intravenously for an extended period of time (1-2 weeks) in order to treat cerebral vasospasm.\u0000It might be possible to substitute a sustained-release biodegradable formulation for the\u0000ongoing intravenous infusion used in this traditional therapy.\u0000\u0000\u0000\u0000The primary goal of this study was to formulate and evaluate the potentiality of ethosomes\u0000to deliver nimodipine, a potent water-insoluble anti-hypertensive drug, through the deeper layers of the\u0000skin. The greatest challenge for drug formulation is its poor oral bioavailability and solubility.\u0000\u0000\u0000\u0000Nimodipine-loaded ethosomal gel was developed for transdermal drug delivery to increase\u0000solubility and skin penetration and to promote oral bioavailability. Central composite design\u0000employing a thin-film hydration method was used to prepare and optimize ethosomes. A better\u0000dispersion medium for nimodipine's preparation in ethosomes was selected based on the effect. The\u0000design consisted of independent variables as lipid (X1), ethanol (X2), and sonication time (X3).\u0000Concentrations were manipulated to examine the effects on three responses, namely the %entrapment\u0000efficiency (Y1), vesicle size (Y2), and %cumulative drug release (Y3).

The preparation of\u0000ethosomal gel formulations began with incorporating a single ethosomal formulation (F4) into various\u0000concentrations of gelling agents. These studies performed physicochemical characterization,\u0000compatibility testing, and in vitro drug release tests on ethosomal gels. In vivo studies involving hypertensive\u0000rats were conducted after skin permeation, and ex vivo studies were performed. In order\u0000to assess the drug's permeability and deposition, we employed the abdomen skin of rats.\u0000\u0000\u0000\u0000The optimal process parameters resulted in ethosomes with 89.9 ± 0.19 percent entrapment\u0000efficiency, a vesicle size of 102.37 ± 5.84 nm, and a cumulative drug release of 98.3 ±\u00000.13%. pH and drug content measurements were consistent with the homogeneous ethosomal\u0000gels.

Evaluation of the polyphenols and flavonoid content\u0000in the extract was also performed.\u0000\u0000\u0000\u0000A calcium oxalate nephrolithiasis case was established in rats by adding ethylene glycol\u0000(1%) to the rats' daily drinking water for a duration of one month. Treatment was achieved by\u0000oral co-administration of RMAE to rats administrated ethylene glycol.\u0000\u0000\u0000\u0000Phytochemical results showed that LC/MS-MS analysis led to the identification of 37\u0000compounds in the phytoconstituent profile of RMAE. The biochemical results revealed significant\u0000improvement in serum kidney functions (urea, creatinine, and uric acid) in addition to restoring\u0000the calcium x phosphorous product and parathyroid hormone (PTH) levels in the plant-treated\u0000group compared to the non-treated one. The data have been supported by the significant decrease\u0000in lactate dehydrogenase enzyme (LDH) expression in the liver tissues, reflecting the decrease in\u0000oxalate synthesis in the liver compared to the non-treated group. Kidneys' histological examinations\u0000showed the absence of oxalate crystals in the treated group and the immunohistochemical\u0000findings of osteopontin (OPN) protein revealed the impact of RMAE on OPN expression in kidney\u0000tissues. Improvements in the femur bone fractures and the parathyroid gland in the treated\u0000group were also noticed during microscopic examinations.\u0000\u0000\u0000\u0000The anti-lithiatic effect of the extract was attributed to its influence on serum phosphate,\u0000serum PTH, and OPN levels in kidney tissues and decreasing synthesis of LDH in liver\u0000tissues in addition to the prevention of secondary disease incidences, such as secondary hyperparathyroidism\u0000and cardiovascular diseases. On the other hand, the plant's considerable content\u0000of phenolics and flavonoids has been found to play a role in controlling kidney stone progression\u0000episodes.\u0000","PeriodicalId":10772,"journal":{"name":"Current Bioactive Compounds","volume":"23 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139963355","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}
