Pharmaceutically speaking, OLM is a class II medication (low solubility, high permeability) that is practically insoluble.Due to its extremely poor solubility, which negatively affects its usefulness, oral medication have a low (26%) bioavailability. The current strategy involves generating OLM as a micellar dispersion in the nano range scale utilizing the film hydration process. In order to prepare transparent aqueous formulations, increase drug solubilization, and administer medication orally, Soluplus (SLP) was employed as a micellar nanocarrier.Different SLP concentrations were used to make eight formula

It is caused by mutations in the CTNS gene that encodes the cystine transporter, cystinosin, which leads to lysosomal cystine accumulation. It is the major cause of inherited Fanconi syndrome, and should be suspected in young children with failure to thrive and signs of renal proximal tubular damage. The diagnosis can be missed in infants, because not all signs of renal Fanconi syndrome are present during the first months of life. Elevated white blood cell cystine content is the cornerstone of the diagnosis. Since chitotriosidase (CHIT1 or chitinase-1) is mainly produced by activated macrophages both in normal and inflammator

Naproxen is non-steroidal anti-inflammatory drug, which has antipyretic and anti-inflammatory effect. It is extensively bound to plasma albumin, and exhibits gastric toxicity, so it may be more efficient to deliver the drug in its sustained release dosage form and adequate blood level is achieved. Three liquid formulations with in situ gelling properties have been assessed for their potential for the oral sustained delivery of naproxen . The formulations were dilute solutions of: (a) pectin; (b) gellan gum and; (c) sodium alginate, all containing complexed calcium ion that form gels when these ions are released in the acidic environment of the stomach . The viscosity of the sols and drug release were measured, and was found to be depende

It was postulated that cilnidipine would mitigate the liver damage linked to cholestasis by its confirmed farnesoid x receptor (FXR) activation. Hence, this study aimed to examine the impact and potential anticholestatic capabilities of cilnidipine in the rat’s model of cholestasis produced by α‑naphthyl isothiocyanate (ANIT), which is a widely used model that resembles human cholestasis. The white albino rats used in this investigation were separated into three distinct groups, with eight in each group. Negative control (Group I), in this group, rats ge
