Buy Cheap Famciclovir (Famvir) No Prescription 250mg

After oral administration, famciclovir is well absorbed (systemic availability 77%), with little intersubject variability, and is rapidly converted to penciclovir. This compares favorably with aciclovir, the absorption of which is slow and incomplete, with a highly variable systemic availability of only 10-20%.

Order Valtrex (Valaciclovir) No Prescription 500/1000mg

Valaciclovir is the L-valyl ester of aciclovir. After oral administration, it is rapidly and extensively converted to aciclovir by first-pass metabolism, resulting in plasma aciclovir concentrations previously only attainable with intravenous administration.

Anti-Infective Therapy

Despite dire warnings that we are approaching the end of the antibiotic era, the incidence of antibiotic-resistant bacteria continues to rise. The proportions of penicillin-resistant Streptococcus pneumoniae, hospital-acquired methicillin-resistant Staphylococcus aureus, and vancomycin-resistant Enterococcus strains continue to increase. Community-acquired methicillin-resistant Staphylococcus aureus is now common throughout the world.

Cidofovir

Cidofovir undergoes intracellular phosphorylation by cellular kinases to the antiviral metabolite, cidofovir diphosphate, which acts as a competitive inhibitor of viral DNA polymerase. It is active against a range of herpesviruses including CMV, and, since its activity is not reliant on viral enzymes, may retain activity against some aciclovir- and foscarnet-resistant viruses. Cross-resistance with ganciclovir is common.

Order Acyclovir (Zovirax) No Prescription 200/400/800mg

Acyclovir is active against herpes simplex virus type 1 and type 2 and against varicella-zoster virus. This activity requires intracellular conversion of aciclovir by viral thymidine kinase to the monophosphate with subsequent conversion by cellular enzymes to the diphosphate and the active triphosphate.
