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.

Use mosquito repellant nets-some chemicals such
as permethrin which is a chemical used as a
mosquito repellant sprayed on the clothes and
mosquito nets.
• Permethrin 0.5 to 1% is available in various chemists as over the counter medication which is effective for at least 2-6 weeks and may last for up to 1 year even through laundering if its concentration is higher such as in the already treated mosquito nets that last 1 to 4 years or in tablets used for treating mosquito nets. DEET (N, N-diethyl-m-tiluamide) is also approved
chemical for skin application on the exposed parts of
the body such as hands, legs as a mosquito repellant
which may last 4-6hours.Its available in 15-33% in
chemists and major hospital pharmacies and offers
97% protection.
• When combined DEET and Permethrin offers 99.9% protection against mosquitoes. Among locally available brands includes: Mijex gel/spray and Mosout spray. These chemicals are not harmful to the body as they are poorly absorbed, and are rapidly deactivated -their rare side effects include itching, redness and dizziness. They should not be applied to the eyes, mouth or broken skin. In addition:
