RESUMO
BACKGROUND: Obesity has become a prevalent issue worldwide, leading to various complications such as hyperlipidemia, diabetes, and cardiovascular problems. Statins, as FDA approved anti-hyperlipidemic drugs, still pose some concerns upon their administration. Recently, researchers have looked for natural products as an alternative to manage hyperlipidemia and obesity. AIM: This work aimed to study the hypolipidemic effect of Lepidium sativum garden cress (GC) from different preparations; orally administered seeds, and hydrogel, in comparison to atorvastatin. METHODS: GC hydrogel was prepared from the GC aqueous extract and pharmaceutically evaluated for its pH, spreadability, seeds content, homogeneity, rheology, and in vitro release. The rat's body weight, blood glucose levels, total lipid profile, and liver biomarkers were evaluated on obese rats for one month. In addition, the histopathology study was also performed. RESULTS: GC hydrogel had acceptable pharmaceutical properties and showed a sustained release performance over 24 h. Oral and topical GC significantly reduced the lipid profiles, blood sugar and ALT, AST levels more than the negative control group and comparable to atorvastatin. It was found that oral GC showed a significant effect on the percentage decrease in the rat's body weight than the applied hydrogel. Histopathology study revealed a better outcome in the histological structure of pancreas and liver compared with rats feed on high fat diet post-treatment for one month. CONCLUSION: GC orally administered, or topically applied hydrogel could be a promising, safe alternative formulation to atorvastatin in managing hyperlipidemia and normalizing body weight of obese rats.

BACKGROUND: Lepidium sativum, Garden Cress (GC), seeds have a lot of natural molecules with a pronounced activity against different disorders. It was reported that GC seeds have the ability to lower the blood glucose level. AIM: The aim of this work was to formulate GC seeds into oral tablets containing a fixed dose of the grounded seeds. Furthermore, the anti-diabetic performance of the prepared tablets was studied in the streptozotocin rats' model in comparison with positive control metformin. METHODS: Micrometrics of GC grounded seeds with different excipients were investigated. Then, GC tablets were prepared via direct compression technique. GC tablets were characterized for their uniformity of dosage unit, friability, hardness, disintegration time, and in vitro release. The antidiabetic effect was studied in rats for a period of 28 days. Glycosylated hemoglobin, liver performance, and lipid levels include total cholesterol (TC), triglycerides (TGs), high-density lipoprotein (HDL), and low-density lipoprotein (LDL) were also estimated. In addition, histopathological study of liver and pancreas was also performed. RESULTS: Prosolv®EasyTab produced tablets with higher hardness, lower disintegration time, and fast release. GC tablets significantly lower the elevated blood glucose level. In addition, they have antihyperlipidemic activity, hepatocellular protective role and restore the histology of the liver and pancreas. CONCLUSION: GC tablets could be a promising alternative formulation to control the high blood glucose level in diabetic rats rather than chemically derivatized drugs.
