Sildenafil blockiert die Phosphodiesterase-5 und steigert dadurch die intrazellulären cGMP-Konzentrationen. Die Wirkung setzt innerhalb von 30 bis 60 Minuten ein. Seine Halbwertszeit von vier Stunden macht den Wirkstoff zu einem Präparat mit kurzer Wirkdauer. Der Abbau erfolgt über CYP3A4 und CYP2C9, und die Elimination ist überwiegend biliär. Nebenwirkungen wie Kopfschmerzen und Hautrötungen sind vasodilatationsbedingt. Der Begriff viagra kaufen taucht häufig im Zusammenhang mit dem pharmakologischen Standard dieser Substanzklasse auf.

  • AmazonianInLove - Shoes that never Yield to the FloorIf you are looking for a shoe that will never yield to the floor, pressure or good ol' fashioned boy's club bullying this is the shoe for you. It has been tested for hours, opportunities to yield to oppression were presented yet this shoe stayed firmly in place holding up half the sky for 13 hours.

    Highly recommended.
  • Alan McGaughey - love the heck out of my new asus t prime!!!Been waiting for months to find one of these. I lucked out and found one locally. I read all the hype, and was looking for a mind blowing piece of hardware. Well, the Prime is everything I hoped it would be, and more. I'm a tech nerd so I'm hard o please. And I am very pleased.

    The tegra 3 processor is a winner! Extremely fast. This machine is not really a quad core... IT'S A FIVE C0RE!! Four performance cores and companion core which takes care of a lot of the system overhead.

    The display is super crisp and clear, displaying stunning, extremely smooth and fast graphics. Water physics is unbelievably lifelike on the Prime.

    Super thin and very light.
    Yes, it has one External speaker, but the sound is very good and if I want louder, I use earplugs.

    Plenty of apps, games are wonderful on this beast. I also installed Ice Cream Sandwich with no probs.

    I have had no problems with GPS or wifi. Everything worked perfect right out of the box.

    I also downloaded an app which let me tether the tablet to my Samsung charge so I have internet access anywhere I need it.

    ASUS has been of of my favorite tech companies for many years, and they hit a major home run with the Transformer Prime.
