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. Multiresistant Acinetobacter and Pseudomonas are everyday realities in many of our hospitals. The press is now warning the lay public of the existence of "dirty hospitals." As never before, it is critical that health care providers understand the principles of proper anti-infective therapy and use anti-infective agents judiciously. These agents need to be reserved for treatable infections — not used to calm the […]

Antimicrobial therapy: general principles

A wide variety of antimicrobial agents is available to treat established infections caused by bacteria, fungi, viruses, or parasites. This section will cover the general principles of antimicrobial therapy and will also include illustrative clinical problems to emphasize proper decision-making in using antimicrobials. Determinants of Antimicrobial Efficacy Measurement of antimicrobial activity in vitro Susceptibility testing is indicated for any bacterial pathogen warranting chemotherapy. Drugs that irreversibly destroy the ability of an organism to replicate, and perhaps in the process destroy the structural integrity of the organism, are microbicidal. Drugs that reversibly impair replicating ability, with this function being restored when drug concentrations fall below critical inhibitory levels, are microbiostatic. In quantitative […]

Order Famciclovir (Famvir) No Prescription 250mg

Famvir (Famciclovir) for Shingles Indication: herpes zoster (shingles) Drug Tradename: Famvir Manufacturer: Novartis Pharmaceuticals Corporation Other drugs mentioned: * Zovirax (Acyclovir) * Valtrex (Valaciclovir) * Cytovene (Ganciclovir) The FDA has granted marketing approval for famciclovir (Famvir/SmithKline Beecham) for the treatment of herpes zoster (shingles). Shingles is caused by the same virus – varicella-zoster virus (VZV) – that causes chickenpox. VZV is initially transmitted primarily by aerosolized droplets from skin lesions. The virus replicates in the respiratory tract, moves to the bloodstream, and then migrates to the epithelium, where infection is manifested by varicella blisters. The virus is capable of traveling up sensory nerves from the skin to the dorsal root ganglia, […]
