Development of extended release oral formulations of dexketoprofen trometamol (DT), a rapidly eliminated drug with high solubility, poses a great challenge especially when a portion of the dose is to be absorbed from the colon. In this study, site-specific release retardant mini-matrix tablets (SSRRMT) were developed and functionally coated with pH-responsive materials to achieve a site-specific delivery of DT at the duodenojejunal (DSRRMT) and ileocecal (ISRRMT) regions. Stomach-specific coated mini-tablets (SSCMT) were manufactured for immediate release of about 16% of the daily dose of DT in the stomach...

Halogenated boroxine dipotassium trioxohydroxytetrafluorotriborate, K2 [B3 O3 F4 OH] (boroxine) was previously shown to be very effective in inhibition of several carcinoma cell lines, including the skin cancer. Here, we investigated its antimicrobial potential by targeting the multidrug-resistant opportunistic pathogens associated with skin and wound infections. The antimicrobial testing against eleven bacterial and four fungal species revealed good activity of boroxine against pathogenic filamentous fungi Penicillium funiculosum and Aspergillus niger (MIC50 64 and 128 µg/ml), and a moderate bioactivity against the yeast Candida albicans (MIC50 512 µg/ml)...

OBJECTIVES: Development and evaluation of rapidly dissolving film for intra-oral administration of naftopidil. SIGNIFICANCE: Formulation of naftopidil in the form of rapidly dissolving buccal film can eliminate the dissolution problem of naftopidil and provide greater chance for direct absorption into the systemic circulation bypassing the presystemic metabolism. This can improve the oral bioavailability. In addition, this film guarantees patient compliance and is suitable for geriatric patients...

Numerous normal and tumors cells are well-known to express the somatostatin receptors (SSTRs) on their surface which make the receptor be useful for tumor scintigraphy. Thus, identification of SSTRs is beneficial, especially SSTR2. The somatostatin analogue, Octreotide (OCT) was chosen as a ligand, as it is known to selectively bind to SSTR2. Moreover, polyethylene glycol (PEG), 8armPEG was used as a branched PEG to provide a low non-specific cell binding and easily chemical modification. OCT, and fluorescein (Flu) were conjugated to branched PEG using a water-soluble carbodiimide (EDC) and N-hydroxy succinimide (NHS) so as to activate its carboxylic acid group...

Objectives : The aim of the study was to deliver effective doses of Quercetin (Que) to the lower region of hair follicles (HFs) using the transfollicular route through dipalmotylphosphatidylcholine (DPPC) reinforced poly lactide- co- glycolide nanoparticles (DPPC-PLGA hybrid NPs) for the treatment of alopecia. Method: PLGA and DPPC-PLGA hybrid NPs were prepared by double emulsification solvent evaporation method. NPs were characterized for size, shape, zeta potential entrapment and drug release. Drug-polymer interactions were determined by infrared spectroscopy (FTIR) and differential scanning calorimetry (DSC)...

This work aims at the formulation of nasal nano-emulgel for resveratrol, employing carbopol 934 and poloxamer 407 as the gelling agent. The optimum nano-emulsion was determined through further characterization of the selected system. The nasal nano-emulgel was prepared and tested for the in vitro release, the release kinetics, FTIR, ex vivo permeation, nasal mucosa toxicity and in vivo pharmacokinetic study...

Metronidazole, a BCS class I drug, could be waived based on the BCS principles, thus enabling in vitro dissolution data as a surrogate of BE study. However, the impact of dissolution profiles of metronidazole tablets on the in vivo performance has never been studied systematically. So the aim of the present study was to conduct a multipronged approach of in vitro dissolution, in silico simulation and in vivo study to evaluate the effect of dissolution performance on oral absorption of metronidazole tablets, as well as the accuracy of PBPK model to predict the oral bioavailability for BCS I drug...

Mefenamic acid (MA) has been reported as a weakly soluble drug which presents weak in vivo absorption upon oral administration using conventional formulations. Solid dispersions (SDs) have been investigated extensively in literature for enhancing the solubility and bioavailability of weakly-soluble molecules. Hence, the aim of proposed study was to prepare MA novel formulations in the form of SDs using hot-melt extrusion technology in order to enhance its palatability, bioavailability and pharmacodynamics effects/anti-inflammatory efficacy...

Meloxicam (MX), a nonsteroidal anti-inflammatory drug, widely used to treat arthritis, has a very bitter taste. Chemical modification of the bitter functionality was achieved by synthesis of a prodrug, meloxicam pivalate (MXP). Taste improvement was evaluated using single bottle-test rat model. It was found that palatability of MXP solution improved significantly as compared to MX.

Nanomaterial based anticancer treatment is promising nowadays because of their small size that can penetrate and interact both inside and outside the cell surface. In this study, a simple protocol was followed for the conjugation of the biologically synthesized selenium nanoparticles (SeNPs) and short chain synthetic peptide. SeNPs was synthesized by using the culture supernatant of Streptomyces griseoruber, actinomycetes isolated from the soil. The short chain peptide Boc-L-F-OMe was synthesized by the conventional solution phase chemistry using a racemization-free fragment condensation strategy...

Sorbitol is a popular sugar alcohol which has been used as an excipient in formulations of various drugs. Although from a safety perspective the presence of sorbitol in drug formulations does not raise a concern, reports have emerged and these suggest that sorbitol in drug formulations may alter oral absorption and bioavailability of certain drugs. The focus of this paper was to review the published literature of various drugs where pharmacokinetic data has been reported for the drug alone versus drug administered with sorbitol and provide perspectives on the pharmacokinetic findings...
