Recent pharmaceutical research has focused on controlled drug delivery having an advantage over conventional methods. Adequate controlled plasma drug levels, reduced side effects as well as improved patient compliance are some of the benefits that these systems may offer. Controlled delivery systems that can provide zero-order drug delivery have the potential for maximizing efficacy while minim...
to evaluate the physical and chemical stability of a suspension of mycophenolate mofetil (mmf) prepared in the hospital from commercially available mmf capsules and tablets. extemporaneous pharmacy was used as a feasible method in this experimental study to prepare suspension form of mmf. suspension formulations were prepared from both tablets and capsules forms of mmf. thereafter the stability...
Extended-release matrix tablets of diltiazem hydrochloride (DTZ) were prepared using waxy materials alone or in combination with Kollidon SR. Matrix waxy materials were carnauba wax (CW), bees wax (BW), cetyl alcohol (CA) and glyceryl monostearate (GMS). Dissolution studies were carried out by using a six stations USP XXII type 1 apparatus. The in vitro drug release study was done in 1000 ml ph...
Two mini-columns partially filled with granular activated carbon (GAC) and/or a natural zeolite, covered by a bacterial biofilm of Arthrobacter viscosus, were used in a continuous flow system to remove Cr (VI) from solutions with initial concentration of 70mg/l and a working pH ranging between 4.5 and 5.5. Three different set-up's were used: two columns in series filled GAC covered with a biofi...

The aim of this study was to evaluate the effect of different capsule filling manufacturing techniques and storage conditions on the release of the active ingredients from herbal capsules during the dissolution test in vitro. Different techniques for the preparation of the original mixture of dry extracts were applied, and subsequently capsules with six different fillings were prepared. The sta...
The study was designed to investigate the impact of colonic pH changes on formulated colon targeted Mesalamine matrix tablets in the treatment of inflammatory bowel disease (IBD). Mesalamine tablets were fabricated with guar gum as Polymer system. The different batches of Mesalamine tablets (GMM1GMM6) were compressed with increasing proportion of guar gum and HPMC E15 LV. The different buffer c...
The present work deals with the development of a prolonged release matrix tablet readily soluble drug pramipexole. new excipient Kollidon SR (a mixture 80% polyvinyl acetate and 20% polyvinylpyrrolidone) hypromellose K15M were used as polymers to control from selected prototypes. Various polymer concentrations tested achieve stable pH independent pramipexole 0.26 mg over 24 hours; samples prepa...
This study aimed to improve the dissolution rate of aceclofenac and release drug in a controlled manner over period 24 hours. Matrix tablets were prepared by direct compression method, using hydrophilic polymers (HPMC/guar gum). wet granulation method different Tablets evaluated for vitro profile phosphate buffer with pH 6.8 (without enzymes). The thickness hardness 3.23 ± 0.035 3.28 0.008 mm 3...
