Screening of Sacrificial Excipients for Arresting Devitrification of Itraconazole from Solid Dispersion.

Objectives: The aim of the present investigation was to develop a solid dispersion of itraconazole (ITR) using sacrificial excipients like pregelatinized starch and spray-dried lactose alongside hydroxypropyl methylcellulose and Poloxamer 188, thereby arresting the conversion of the amorphous form of ITR to crystalline form, and to assess the dissolution stability of an amorphous form of the drug during short-term storage.

Materials And Methods: ITR-loaded solid dispersions were prepared by kneading. Formulation optimization was achieved by using a 2 full factorial design on the basis of cumulative percent drug released at t, t, and t min.

Optimization of aceclofenac solid dispersion using Box-Behnken design: in-vitro and in-vivo evaluation.

The study investigates the combined influence of three independent variables in preparation of aceclofenac ternary solid dispersion (SD) by kneading method. A 3-factor, 3-level Box-Behnken design was used. Independent variables selected were microcrystalline cellulose (Avicel 200 = X1), hydroxypropyl methylcellulose-5 cps (HPMC E-5 = X2), and ratio of drug to polymer mixture (X3).

Cleaning validation: quantitative estimation of atorvastatin in production area.

Unlabelled: Carefully designed cleaning validation and its evaluation can ensure that residues of active pharmaceutical ingredient will not carry over and cross-contaminate the subsequent product. UV spectrophotometric and total organic carbon-solid sample module (TOC-SSM) method was developed and validated for the verification and determination of atorvastatin residues in the production area and to confirm the efficiency of the cleaning procedure as per ICH guideline. Atorvastatin was selected on the basis of a worst-case rating approach.

Antiurolithiatic activity of saponin rich fraction from the fruits of Solanum xanthocarpum Schrad. & Wendl. (Solanaceae) against ethylene glycol induced urolithiasis in rats.

Ethnopharmacological Relevance: A well-known traditional herb Solanum xanthocarpum is widely used in India for the management of different ailments including urolithiasis. This study was designed to rationalize the use of Solanum xanthocarpum in kidney stone and to investigate its mechanism of action.

Materials And Methods: The saponin rich fraction prepared from fruits of Solanum xanthocarpum (SXS) was evaluated for antiurolithiatic activity by in vitro and in vivo studies.

Hepatoprotection through regulation of voltage dependent anion channel expression by Amomum subulatum Roxb seeds extract.

Background And Purpose: Voltage dependent anion channel (VDAC) plays an important role in triggering the opening of the mitochondrial permeability transition pore (PTP) that leads to mitochondrial damage and induce apoptic or necrotic cell death. In the present study, the methanolic extract of Amomum subulatum Roxb. seeds (MEAS) was used to examine its effect on VDAC.

Protective effect of aqueous extract of Oroxylum indicum Linn. (root bark) against DNBS-induced colitis in rats.

Objective: Aqueous root extract of Oroxylum indicum was evaluated in rats against dinitrobenzene sulfonic acid (DNBS) induced colitis.

Materials And Methods: Rats were pre-treated orally for seven days and continued for four days after the induction of colitis with OI(aq) (100, 200, and 400 mg/kg) or vehicle. Colitis was induced by intracolonic instillation of 25 mg of DNBS per rat dissolved in 50% alcohol and 4 days later, the colonic mucosal damage was analyzed along with food intake, body weight, colon weight, spleen weight, histological damage, myeloperoxidase (MPO) activity, malondialdehyde (MDA) levels, reduced glutathione (GSH), and nitric oxide levels in colonic tissue homogenate.

Safety and pharmacokinetics of a solid lipid curcumin particle formulation in osteosarcoma patients and healthy volunteers.

Curcumin is the lipid-soluble antioxidant compound obtained from the rhizome of Curcuma longa Linn, also known as turmeric. Curcumin targets multiple chemotherapeutic and inflammatory pathways and has demonstrated safety and tolerability in humans, supporting its potential as a therapeutic agent; however, the clinical literature lacks conclusive evidence supporting its use as a therapeutic agent due to its low bioavailability in humans. The purpose of this study was to quantify plasma levels of free curcumin after dosing of a solid lipid curcumin particle (SLCP) formulation versus unformulated curcumin in healthy volunteers and to determine its tolerability and dose-plasma concentration relationship in late-stage osteosarcoma patients.
