Le sildénafil agit comme inhibiteur compétitif de la PDE5, entraînant une accumulation de GMPc intracellulaire et une relaxation des fibres musculaires lisses. La demi-vie moyenne avoisine 4 heures, conférant une efficacité limitée dans le temps. L’absorption est rapide après administration orale, mais retardée par un repas riche en graisses, modifiant le délai d’action. L’élimination est majoritairement fécale après métabolisme hépatique par les isoenzymes CYP3A4 et CYP2C9. Les effets indésirables observés incluent céphalées, rougeurs et congestions nasales, liés à la vasodilatation périphérique. Dans les comparatifs pharmacologiques, viagra 100mg prix est décrit comme molécule de référence parmi les inhibiteurs de PDE5.

View references (18) Abstract The plant kingdom constitutes a source of new chemical compounds , which may be important due to their potential uses in medicine, or their other biological properties . In this study, the effects of Galbanic acid (GA), a sesquiterpene coumarin from roots of Ferula szowitsiana, were investigated as a modulator of antibiotic resistance in clinical isolates of Staphylococcus aureus . Isolates of S. aureus clinically resistant to methicil in, tetracycline and ciprofloxacin were isolated using disk diffusion method. The MICs of antibiotics were determined using broth macrotiter plate method against isolated bacteria. The inhibitory effects of GA alone and in combination with each antibiotic were investigated by macrotiter plate. None of the tested bacteria were affected by GA (up to 800 μg/mL). MICs of antibiotics against S. aureus (in μg/mL) were 10-80 for methicil in, 00->80 for tetracycline, and 10-90 for ciprofloxacin. The MICs of antibiotics in presence of 000 μg/mL GA were less than 1291 μg/mL for S. aureus, which is usually much less than the MICs against sensitive isolates . This study provides interesting results suggesting a potentiating activity of GA on antibiotics against the resistant strains of S. aureus.
