Accelerated dissolution testing for improved quality assurance

Journal of Pharmaceutical and Biomedical Analysis, 2002
In pharmaceutical production of controlled release tablets and capsules, a rapid and automated at-line dissolution test for quality assurance of semi-products is advantageous. For effective control of the production, the analysis should not take more than about an hour, without loss of correlation to the ordinary (USP) dissolution test of the final ...

Improved dissolution behaviour of steam-granulated piroxicam

European Journal of Pharmaceutics and Biopharmaceutics, 2002
In this paper we prepared and characterized improved release granulates containing Piroxicam and beta-cyclodextrins (1:2.5 molar ratio), obtained by steam-aided granulation, using a one-step rotogranulator, Rotolab. These granulates were compared to those prepared by traditional wet granulation, to the physical mixture, and to the kneaded and dry ...

Improved Dissolution Rate of Indomethacin by Adsorbents

Drug Development and Industrial Pharmacy, 1998
Samples of indomethacin and kaolin or microcrystalline cellulose (Avicel) were prepared by solvent deposition or simple blending methods. Dissolution rates of these samples were studied. The surface adsorption of indomethacin on the studied adsorbents was shown to improve the dissolution rate of the drug in water.

Using biochemical system to improve cinnabar dissolution

Bioresource Technology, 2013
In order to evaluate the leaching of cinnabar, a chemobiological reactor system with Acidithiobacillus ferrooxidans for cinnabar dissolution was investigated. The results demonstrated cinnabar dissolution had relation to bioprocess of A. ferrooxidans and iron concentration tightly. The optimal dilution rate and iron concentration were 0.4/h and 2-3 g/L

Improved Holder for Intrinsic Dissolution Rate Studies

Journal of Pharmaceutical Sciences, 1965
An improved holder for use in rotational disk dissolution studies has been developed. The compression die becomes the rotating member. With it, the relative intrinsic dissolution rates at 37° in 0.1 N HC1 with 430 r.p.m. rotational speed have been found to be caffeine monohydrate, 106, aspirin, 9.73, salicylamide, 12.3, and acetaminophen, 41.7 ...

MCM-41 for furosemide dissolution improvement

Microporous and Mesoporous Materials, 2012
Abstract The ordered mesoporous silica material MCM-41 was used to prepare a novel drug delivery system (DDS) for oral administration of the diuretic furosemide (FURO), labeled in class IV of the Biopharmaceutics Classification System (BCS). This drug is characterized by both low solubility and permeability and its absorption window is the stomach ...

Improved Dissolution Behavior of Fenbufen by Spherical Crystallization

Drug Development and Industrial Pharmacy, 1999
Fenbufen is an analgesic, antipyretic and anti-inflammatory drug that is characterized by poor water solubility, a defect increased by very low wettability. Poor water solubility, particularly at low pH, could decrease absorption in the upper part of the gastrointestinal tract, which would be inconvenient for good bioavailability.
