The present study was aimed to develop once daily extended release matrix tablets of minocycline hydrochloride, using hydroxypropylmethylcellulose either alone or in combination with ethyl cellulose as the matrix material in different proportions. The formulated tablets were also compared with a marketed product. The results of the dissolution study indicate that formulations FC-IV, FC-V and FC...

In this comprehensive review, we report on the preparation of graft-copolymers of cellulose and cellulose derivatives using atom transfer radical polymerization (ATRP) under homogeneous conditions. The review is divided into four sections according to the cellulosic material that is graft-copolymerised; (i) cellulose, (ii) ethyl cellulose, (iii) hydroxypropyl cellulose and (iv) other cellulose ...

      Losartan potassium is a well known orally active non-peptide angiotensin II receptor antagonist. Losartan potassium and its principle active metabolites block the vasoconstrictor and aldosterone secreting effect of angiotensin II by selectively blocking the binding of angiotensin II to AT1 receptors. The drug is reported to promote the decrease in ventricular hypertrophy, salt ...

Abstract: Aim and Objectives: The main motto of this work was to search the additive effect Datura stramonium leaves mucilage in making buccoadhesive film by taking Aceclofenac as a model drug. Materials Methods: Nine formulations buccal films were made using Carbopol 934 P varying proportions Ethyl Cellulose D. mucilage. judged for compatibility studies physical constraints including content d...

Tosylation and acylation of cellulose were performed under mild reaction conditions using imidazolium based ionic liquids (ILs) as solvents. The non-degradative nature, lower viscosity, as well as higher solubility of cellulose in [amim]Cl encouraged us to carry out the reactions in this media. The reactions described here were optimised for this particular solvent in order to obtain different ...

A series of metal-modified phosphotungstates were prepared and performed for direct synthesis of ethyl levulinate from fructose in ethanol. Considering the cost of catalysts, catalytic activity of catalysts, and easy separation of catalysts together, K-HPW-1 was chosen as the most suitable catalyst for synthesis of ethyl levulinate from fructose. A high ethyl levulinate yield of 64.6 mol% was o...

Controlled radical polymerization has proven to be a viable route to obtain polymers with narrow polydispersities (PDI’s) and controlled molecular weights under simple reaction conditions. It also offers control over the chain‐ends of the synthesized polymer. Atom transfer radical polymerization (ATRP) is the most studied and utilized of these techniques. In this study ATRP has ...

The objective of the present investigation is to formulate Nizatidine loaded superporous floating hydrogel tablets. In the present study Nizatidine floating tablets were prepared by effervescence method using sodium bicarbonate as a gas generating agent. The tablets were formulated using direct compression technology by employing polymers like chitosan, carbopol 934p and ethyl cellulose. The pr...

Cellulose derivatives containing associating hydrophobic groups along their hydrophilic backbone are used as rheology modifiers in the formulation of water-based spray paints, medicinal sprays, cosmetics and printable inks. Jetting and spraying applications of these materials involve progressive thinning and break-up of a fluid column or sheet into drops. Strong extensional kinematics develop i...

We investigated the adsorption and chemical conjugation of avidin and its deglycosylated form, neutravidin, on films of regenerated and nanofibrillar cellulose. The dynamics and extent of biomolecular attachment were monitored in situ by quartz crystal microbalance microgravimetry and ex situ via surface analyses with atomic force microscopy and X-ray photoelectron spectroscopy. The installatio...
