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...

Stability testing of an active substance or finished product provides information of the variation of drug substance or final product with time influenced by a variety of environmental factors such as temperature, humidity and light. Knowledge gained from stability studies enables understanding of the effects of the environment on the drugs. The aim of our study was to determine the stability o...

OBJECTIVE To develop an extemporaneous 1% benznidazole (BNZ) suspension, with masked taste and adequate stability starting from available commercial tablets. The quality of compounding was evaluated through content uniformity measurement and physical and microbiological stability evaluation, under different storage conditions during 90 days. METHODS Six batches of 1% BNZ suspension were prepa...

an oral suspension could a suitable dosage form for the geriatric patients. the calcium alginate coated ion exchange resinate of propranolol hydrochloride were prepared using amberlite ir-120 by solvent evaporation. microcapsules of propranolol hydrochloride resinate were prepared by solvent evaporation technique,the suspensions were prepared by using deionised water as the vehicle. methyl cell...

Micro6s are the sequel to the Micro5 series, newly projected rover prototypes. Micro6 is equipped with a suspension mechanism so called HEXUS, a six wheeled mobility system with actively controllable suspension. Thanks to the new link mechanism, HEXUS has not only good performance as well as PEGASUS, but also has great stability and fault tolerant feature. The paper describes the concept and sy...

Three-dimensional numerical simulations are performed to study the stability of a sedimenting suspension of weakly flexible fibers. It is well known that a suspension of rigid rods sedimenting under gravity at low Reynolds number is unstable to concentration fluctuations owing to hydrodynamic interactions. Flexible fibers, however, reorient while settling and even weak flexibility can alter the...

Ultraviolet–Visible (UV–Vis) spectroscopy was used, in the current investigation, to explore the dispersion and stability of titania nanoparticles in an aqueous media with different types of dispersants. Hydrochloric and nitric acids as well as ammonia were used to determine the stability of the suspension in the acidic region (pH=2.5) and basic area (pH=9.5), respectively. In addition, for mea...

The non-organically supported silver nanoparticles produced via the reduction of silver oxide by hydrogen and acetvlacetone (acac) have unusual stability in aqueous solution. We have previously reported that the negative potential, the hydrophilic surface that is created by the adsorbed hydroxide ions, which resembles an oxide interface, and the low ionic strength of the solution due to the sma...
