Sublingual Fast-Dissolving Thin Films of Loratadine: Characterization, In Vitro and Ex Vivo Evaluation.

Loratadine (LOR) is a second-generation antihistamine that exhibits a low and variable oral bioavailability (10-40%) and delayed onset owing to poor solubility and an extensive first-pass effect. Therefore, in light of the clinical need, the main goal of the present study was to develop sublingual fast-dissolving thin films of LOR-citric acid co-amorphous systems (LOR-CAs) with the aim of eliciting a faster onset and improving the bioavailability. We formulated sublingual fast-dissolving thin films of LOR by a film-casting technique using hydrophilic polymers like hydroxypropyl methylcellulose (HPMC E15), polyvinyl pyrrolidone K30 (PVP K30), and hydroxypropyl cellulose EL (HPC-EF) and citric acid as a pH modulator, while glycerin served as a plasticizer.

Formulation and Evaluation of pH-Modulated Amorphous Solid Dispersion-Based Orodispersible Tablets of Cefdinir.

Cefdinir (CEF) is a semi-synthetic third-generation broad-spectrum oral cephalosporin that exhibits poor solubility at lower pH values. Considering this, pH-modulated CEF solid dispersions (ASDs) were produced by solvent evaporation method employing various hydrophilic carriers and alkalizers. Among different carriers, ASDs produced using PEG 6000 with meglumine as alkalizer were found to significantly increase ( < 0.

Box-Behnken Design-Based Optimization and Evaluation of Lipid-Based Nano Drug Delivery System for Brain Targeting of Bromocriptine.

Bromocriptine (BCR) presents poor bioavailability when administered orally because of its low solubility and prolonged first-pass metabolism. This poses a significant challenge in its utilization as an effective treatment for managing Parkinson's disease (PD). The utilization of lipid nanoparticles can be a promising approach to overcome the limitations of BCR bioavailability.

Leaves Normalize Hormonal Profile and Total Cholesterol in Polycystic Ovarian Syndrome Rats.

In the present study, the beneficial effect of leaves of on testosterone, estradiol, progesterone, LH hormones, blood glucose, and total cholesterol levels in the experimentally induced polycystic ovaries of female Sprague Dawley rats were evaluated. Letrozole was used to induce PCOS in rats, and clomiphene citrate was used as a standard control. This study was carried out in vivo on 30 female rats where group I received normal saline and group II to V were treated with letrozole (1 mg/kg/day), which was dissolved in normal saline orally for 21 days to induce PCOS.
