We describe a simple liquid-scintillation solution for use with water-soluble tritiated compounds that is superior to other such systems. Its advantages include: (1) a refrigerated-type liquid scintillation spectrometer is not needed because the solution has extremely good thermal stability from 22#{176} to 75#{176}C; (2) counting efficiencies are high from pH 1-12, therefore eliminating neutra...
The oral delivery of macromolecules is a topic of much interest as this would undoubtedly improve patient acceptance and compliance with chronic regimens. Heparin and insulin are perhaps among the first candidates that should be considered for oral macromolecule delivery systems. Heparin is the most potent anti-coagulant known for the prevention of deep vein thrombosis and pulmonary embolism, a...
Aceclofenac is an analgesic and anti-inflammatory agent used in the management of osteoarthritis, rheumatoid arthritis and ankylosing spondylitis. The objective of the present work was to investigate the effect of different types of carriers such as polyvinyl pyrrolidone (PVP), polyethylene glycol (PEG) 6000 and sodium lauryl sulphate (SLS) as solubilizer on in vitro dissolution of aceclofenac....
The crystallization of mefenamic acid in transdermal patch is a major problem that makes the patch unstable and decreases the drug release. The additive was used to inhibit crystallization of a mefenamic acid. Among the different types of additives, polyvinylpyrrolidone (PVP) K30 and PVP K90 were studied and found to be highly effective in inhibiting the crystallization of the drug. The PVP pre...
The purpose of this study is to investigate the effects of N-methyl-2-pyrrolidone on the thermosensitive properties of aqueous ethylene oxide-propylene oxide block copolymer (Lutrol(®) F127) system. Due to the aqueous solubility enhancement and biocompatibility, N-methyl-2-pyrrolidone is an interesting solubilizer for the poorly water soluble drugs to be incorporated in the Lutrol(®) F127 syste...
The strategy using nonionic microemulsion as a solubilizer for hydrophobic drugs was studied and is demonstrated in this work. The aqueous phase behaviors of mixed nonionic surfactants with various oils at 37 °C are firstly constructed to give the optimal formulations of nonionic microemulsions with applications in the enhanced solubilization of the model hydrophobic drug, paclitaxel, at 37 °C....
It is important to identify and recover bacteria associating with fungi under natural soil conditions to enable eco-physiological studies, and to facilitate the use of bacterial-fungal consortia in environmental biotechnology. We have developed a novel type of baiting microcosm, where fungal hyphae interact with bacteria under close-to-natural soil conditions; an advantage compared to model sys...
1. Flunixin is a non-steroidal anti-inflammatory drug (NSAID), and a non-narcotic analgesic with antipyretic activities. In veterinary medicine, it is used with meglumine as solubilizer as flunixin meglumine. Flunixin meglumine is used in the alleviation of inflammation and pain associated with musculo-skeletal disorders and colic in horses; the control of acute inflammation associated with inf...
Solid self-microemulsifying drug delivery systems (SMEDDS) have been used increasingly for improving the bioavailability of hydrophobic drugs. Labrasol® and Transcutol® are used widely as surfactant and solubilizer in the formulation of solid SMEDDS. We investigated the effects of spray-drying and the use of different solid carriers on concentrations of Labrasol® and Transcutol® in solid SMEDD...
The aim of this study was preparation and evaluation of ciprofloxacin-containing minitablets for ocular use, in an attempt to obtain prolonged and controlled drug release to the anterior eye segment. Following initial studies on ciprofloxacin powder, it was formulated into ocular minitablets. For this purpose, ciprofloxacin along with various amounts of different sustained release cellulose der...
