Purpose: To develop sustained release matrix tablets of diltiazem hydrochloride (DTZ) using modified karaya gum (MK). Methods: MK was prepared by cross-linking karaya gum with tri-sodium tri-metaphosphate (STMP) which was used as a cross-linker. Matrix tablets of DTZ were prepared using varying ratios of unmodified karaya gum (K) and MK by direct(More)
Purpose: To develop sustained release matrix tablets of diltiazem hydrochloride (DTZ) using karaya gum (K) alone or in combination with locust bean gum (LB) and hydroxypropyl methylcellulose (H). Methods: Matrix tablets of DTZ were prepared at different ratios of drug:gum (1:1, 1:2, and 1:4) and of the gum blends (K, K/LB, K/H and K/LB/H) by direct(More)
This paper deals with the synthesis and characterization of Ghatti gum (GG) and chitosan (CS) IPN MP prepared by emulsion-cross-linking method. Glutaraldehyde (GA) was used as a cross-linker. IPN microparticles were used to deliver (DS) Diclofenac sodium (Model anti inflammatory drug) to the intestine. IPN MP were characterized by Scanning electron(More)
The aim of the present study was to prepare matrix pellets loaded nifedipine (NF) as model drug by pellitization technique by using blend of gelucire 50/13 (GL) and glyceryl palmito stearate (GPS) as hydrophilic and hydrophobic carriers in different concentrations. This system was able to prolong the drug release, minimizing the drug related adverse effects(More)
Two antineoplastic agents, Imatinib (IM) and 5-Fluorouracil (FU) were conjugated by hydrolysable linkers through an amide bond and entrapped in polymeric Human Serum Albumin (HSA) nanoparticles. The presence of dual drugs in a common carrier has the advantage of reaching the site of action simultaneously and acting at different phases of the cell cycle to(More)
OBJECTIVE The rationale behind present research vocation was to develop and investigate a novel microsponge based gel as a topical carrier for the prolonged release and cutaneous drug deposition of fluconazole (FLZ); destined for facilitated fungal therapy. MATERIALS AND METHODS Microsponges were prepared using quasi-emulsion solvent diffusion method(More)
BACKGROUND The management of TB is difficult due to the resistance developed by Mycobacterium tuberculosis against anti-tubercular drugs causes the new challenges for treating and managing the disease. OBJECTIVE The objective of the study was to combat multiple drug resistance (MDR) exhibited by mycobacterium species by synthesizing Dual Drug Conjugate(More)
INTRODUCTION Polyelectrolyte complexes (PECs) are the association complexes formed between oppositely charged particles (e.g., polymer-polymer, polymer-drug and polymer-drug-polymer). These are formed due to electrostatic interaction between oppositely charged polyions. Diclofenac is a nonsteroidal anti-inflammatory drug (NSAID) advocated in use of painful(More)
Purpose: To develop a pH-controlled two-pulse drug delivery system of amoxicillin in order to overcome the snag of biological tolerance and to improve bactericidal activity. Methods: The core tablets were compressed and coated with hydroxylpropyl methylcellulose (HPMC) of different viscosities with spray-dried lactose (SDL) as a pore former. The final(More)
