Delivery of proteins/peptides to the gastrointestinal (GI) tract via peroral/oral route involves tremendous challenges due to unfavorable environmental conditions like harsh pH, presence of proteolytic enzymes and absorption barriers. Detailed research is being conducted at the academic and industrial levels to diminish these troubles and various products(More)
Formulation of nanocrystals is a robust approach which can improve delivery of poorly water soluble drugs, a challenge pharmaceutical industry has been facing since long. Large scale production of nanocrystals is done by techniques like precipitation, media milling and, high pressure homogenization. Application of appropriate stabilizers along with drying(More)
Paclitaxel (PTX) is used as first line treatment for metastatic breast cancer but the relief comes at a heavy cost in terms of accompanying adverse effects. The pharmaceutical credentials of PTX are further dampened by the intrinsically low aqueous solubility. In order to sideline such insidious tendencies, PTX was incorporated in a vitamin E nanoemulsion(More)
Docetaxel (DTX) is favoured option for breast cancer treatment; however its marketed formulation (Taxotere) generates therapeutic response at the cost of undue toxicity. In order to circumvent such limitations, DTX nanocrystals (DTX-NCs) were prepared through high pressure homogenization (HPH) technique using pluronic F-127 (PF-127) as a stabilizer. DTX-NCs(More)
Systemic chemotherapeutic targeting of filarial parasites is unfocused due to their deep seated location in lymphatic vessels. This warrants a prolonged dosing regimen in high doses for an anthelmintic like doxycycline hydrochloride (DOX). In order to provide an alternative, we have constructed ultrafine PLGA nanoparticles of DOX (DPNPs), so as to exploit(More)
Recruitment of inflammatory cells to tumor has been well documented, with the most frequent inhabitants being macrophages termed as tumor associated macrophages, (TAMs). Their presence was thought to be an evidence of immune system initiating a fight response towards the tumor, i.e. immune surveillance. This is the case too initially, when TAMs majorly(More)
OBJECTIVE We explore a plausible method of targeting bendamustine hydrochloride (BM) to circulatory monocytes by exploiting their intrinsic endocytic/phagocytic capability. METHODS We do so by complexation of sodium alginate and chitosan inside dioctyl sulfo succinate sodium (AOT) reverse micelles to form bendamustine hydrochloride loaded nanoparticles(More)
Nanoemulsions are biphasic dispersion of two immiscible liquids: either water in oil (W/O) or oil in water (O/W) droplets stabilized by an amphiphilic surfactant. These come across as ultrafine dispersions whose differential drug loading; viscoelastic as well as visual properties can cater to a wide range of functionalities including drug delivery. However(More)
The scope of RNAi based therapeutics is unquestionable. However, if we dissect the current trend of clinical trials for afore mentioned drug class, some stark trends appear: 1) naked siRNA only exerts influence in topical mode whilst systemic delivery requires a carrier and 2) even after two decades of extensive efforts, not even a single siRNA containing(More)
The aim of the present work was to develop and characterize mucoadhesive film of cellulose (methyl cellulose and hydroxy propyl methyl cellulose) and polymethacrylate (Eudragit RSPO) polymers for buccal delivery of carvedilol. Drug and polymers were found to be compatible as revealed by FTIR and DSC analysis. Mucoadhesive films were prepared by solvent(More)
