En el año 1962 se inició un proceso de investigaciones en fármacos antivirales en los laboratorios de Burroughs Wellcome & Company (actualmente Glaxo Smith Kline), que logró el descubrimiento del aciclovir en 1974 por Howard Schaeffer y Lilia Beauchamp.​ El descubrimiento del aciclovir fue considerado el comienzo de una nueva era en la terapia antiviral, ya que es extremadamente selectivo y posee un bajo nivel de citotoxicidad. Hitchings recibieron el Premio Nobel de Medicina en 1988 debido, en parte, al desarrollo de este compuesto.​ El aciclovir es un análogo de la guanina. Su estructura difiere de otros análogos de nucleósidos en que contiene sólo una parte de éste ya que el anillo glucídico está reemplazado por una cadena abierta. Se considera una prodroga, debido a que su forma original es inactiva, y sus metabolitos son las sustancias antivirales activas. Relacionado con el aciclovir, con mejor biodisponibilidad, está el famciclovir. El aciclovir se usa principalmente por vía oral mediante formulaciones en comprimidos y suspensión para el uso pediátrico. También se administra por vía tópica, en crema, e intravenoso en pacientes con infecciones graves por herpesvirus.​ Este efecto es en función de la dosis y no de la presentación.

    Valacyclovir (Valtrex, marketed by Glaxo Smith Kline) and acyclovir (Zovirax, marketed by Sanofi-Aventis) are used mainly for treatment of genital herpes. Both are antiviral drugs and can be taken orally to shorten herpes symptoms or to prevent this infection from recurring in healthy individuals. Acyclovir pills had been in use from 1991 and enjoying the status of a first-of-its-kind antiviral drug for genital herpes treatment, until Valtrex was approved by the US Food and Drug Administration (FDA) 4 years later in 1995. The valacyclovir vs acyclovir debate started since then and it still remains a matter of research interest as to which drug you can use to cope with herpes better. Valacyclovir advantages Valacyclovir has a number of key advantages over other similar antiviral medications. Clinical trials have shown that this drug has greater effectiveness in dealing with the herpes simplex virus (HSV) or the varicella zoster virus (VZV), compared to acyclovir or other drugs. Another plus factor of Valtrex is that it is probably the only medicine that can reduce the risk of herpes transmission, given that safe sex methods are used. Compared the effectiveness of oral erythromycin and oral acyclovir in the treatment of Pityriasis rosea. One study group was given high-dose oral Acyclovir and another group oral Erythromycin in standard dose. After eight weeks all patients achieved complete response in both the groups. The response to Acyclovir compared with that to Erythromycin was better and was statistically significant. Brivudin (bromovinyl deoxyuridine) is a nucleoside analogue with a high and selective antiviral activity against varicella-zoster virus (VZV) and herpes simplex virus type 1 (HSV-1). Brivudin has a markedly higher anti-VZV potency than oral acyclovir. Brivudin has no nephrotoxic properties, which is an advantage when compared to acyclovir.

    Known as the Henrob, Dillon, Cobra or DHC this oxy-acetylene torch represents welding zen. The wiki definition of zen is achieving a meditative state – and that’s pretty much what you get with this torch, it’s not the fastest welding method but it is the most relaxing by far – and as a bonus it works a number of metals including steel and stainless. My first welder was a stick arc welder and I wanted to add the ability to work thinner steel and to be able to cut steel. It’s done a great job of that for me – and this past year has seen it’s use redoubled as I’ve discovered just how easily it welds stainless steel – really just as easily as regular steel. The real reason for the zen feeling is the soft flame – the torch sees you set your oxygen and acetylene pressures very low – which means you won’t find yourself blowing out your welds. This allows you to produce beautiful welds all the way down to very thin materials easily. The torch also cuts your fuel use considerably compared to my victor set – this isn’t just a great financial benefit but its also a great time savings – oxygen and acetylene tanks are expensive and it’s usually a pain to swap them. I started with a couple of Acetylene B bottles and the comparable size of oxygen cylinder. Order Lasix Cheap Buy Lasix Without Prescription ciprofloxacin bnf Cheap Lasix.
