    Valtrex mechanism of action


    Valtrex (valaciclovir, valacyclovir) is a kind of antiviral drug, which is intended to treat disorders caused by herpes viruses. Particularly, it is also widely used for the treatment of cold sores (oral herpes), shingles (herpes zoster) and genital herpes (herpes B.) Also, it is used to get rid of chickenpox in children over 2 years old. It should be noted that this drug alleviates symptoms, but does not treat the virus itself. After absorption from the intestinal tract, generic valacyclovir is converted to acyclovir triphosphate and amino acid valine (in the liver). Acyclovir triphosphate inhibits replication of viral DNA polymerase, as it invades the viral DNA chain and upsets the DNA strand. After that, the virus loses much of its potential and can no longer do any visible damage to the human body. Even if you do understand the drug’s mechanism of action, pharmacokinetics, pharmacodynamics, and realize the possibility of side effects, do not use it without consulting your doctor. Once you have the first symptoms characteristic of a herpes virus, call your doctor. kamagra opinie Valtrex has been approved as a treatment for recurrent genital herpes (herpes simplex) in otherwise healthy (immunocompetent) adults.

    When it comes to ulcerative colitis, there are different options for treatment. The treatment your doctor prescribes for you often depends on the severity of your symptoms. Two drugs you may hear about are prednisone and prednisolone. (A third drug, methylprednisolone, is stronger than both and should not be confused with prednisolone.) Here’s the rundown on what these drugs are and how they can help treat ulcerative colitis, including how they’re alike and how they’re different. Prednisone and prednisolone both belong to a class of drugs called glucocorticoids. Glucocorticoids reduce inflammation throughout your body. They do this by interfering with the way certain chemicals in your body cause inflammation. These drugs can work in different parts of your body, including your colon. Your colon is the last section of your large intestine, just before your rectum.
