F Kamali et al.
Antimicrobial agents and chemotherapy, 42(5), 1256-1258 (1998-05-21)
The potential effects of concurrent administration of fenbufen and ciprofloxacin on central nervous system activity in healthy young subjects were investigated by electroencephalography (EEG). Visual analog scales (VAS) were used to assess subjective measures of concentration, vigilance, tension, and irritability.
Asif Husain et al.
European journal of medicinal chemistry, 44(9), 3798-3804 (2009-05-22)
The synthesis of a series of 3-[5-(substituted aryl)-1,3,4-oxadiazol-2-yl]-1-(biphenyl-4-yl)propan-1-ones derived from 4-oxo-4-(biphenyl-4-yl)butanoic acid (fenbufen) is described. The structures of these compounds were supported by IR, (1)H NMR, mass spectrometric data and elemental analysis. These compounds were tested for their antiinflammatory, analgesic
Zehadin Gashi et al.
Journal of pharmaceutical sciences, 98(11), 4216-4228 (2009-08-01)
The present work aims at the application of several methods to explain differences in the physical interaction of some aryl propionic acid derivatives (ibuprofen [IBP], ketoprofen [KET], flurbiprofen [FLU], naproxen [NAP], fenbufen [FEN]) with poly(vinylpyrrolidone) (PVP) K30, stored together at

Japanese journal of pharmacology, 76(4), 425-429 (1998-06-12)
Effects of nitric oxide (NO) synthase inhibitors on the enoxacin-induced convulsions were examined in mice pretreated with fenbufen. 7-nitroindazole markedly suppressed the incidence of convulsions, whereas L-arginine did not modify the convulsions at all. The suppression of the convulsions by
P Di Martino et al.
Drug development and industrial pharmacy, 25(10), 1073-1081 (1999-10-26)
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
