This randomized, multi-center parallel-group study will evaluate the safety, pharmacokinetics and the effect on viral load and viral shedding of Tamiflu (Oseltamivir) in patients with influenza. Adult and adolescent patients will be randomized to receive either 100 mg or 200 mg of study drug intravenously every 12 hours. Investigators and patients are blinded to knowledge of the assigned dose of Tamiflu. There is an option to convert to oral Tamiflu after 6 intravenous infusions. The anticipated time on study treatment is 5 days, with an optional treatment extension, if necessary. There will be a non-randomized, open-label treatment group for patients with moderate/severe renal impairment or renal failure. Intravenous dose levels and frequency will be adjusted appropriately to their renal situation.
Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Parallel Assignment, Masking: Double Blind (Subject, Investigator), Primary Purpose: Treatment

Seasonal influenza is responsible for many hospitalizations and deaths each year, despite effective antiviral treatments. Some individuals have medical conditions such as heart or lung dis...
This randomized, double-blind, multi-center study of Tamiflu (Oseltamivir) will evaluate the efficacy against viral activity, the effectiveness in resolving the disease symptoms, and the s...
Due in part to widespread availability of oseltamivir and clinical experience using oseltamivir to treat H5N1 influenza virus infections, many strains of influenza have become resistant to...
The main purpose of this study is to assess the potential exposure of neonates to oseltamivir during lactation by examining oseltamivir concentrations in maternal blood, urine, and breast ...
This study is planned to characterize the pharmacokinetic properties of oseltamivir and the active product--oseltamivir carboxylate--in obesity in order to provide clinical guidance for th...
Influenza season 2007/2008 was marked by a worldwide emergence of oseltamivir-resistant A(H1N1) viruses possessing a mutation in the neuraminidase gene causing His-to-Tyr substitution at amino acid po...
Based on our earlier discovery of N1-selective inhibitors, the 150-cavity of influenza virus neuraminidases (NAs) could be further exploited to yield more potent oseltamivir derivatives. Among the syn...
Oseltamivir phosphate (OP) is the first line therapy for influenza, and its primary metabolite oseltamivir carboxylate (OC) is the active agent via inhibition of neuraminidase of influenza virus. Dosa...
Influenza viruses are respiratory pathogens that are responsible for both seasonal influenza epidemics and occasional influenza pandemics. The narrow therapeutic window of oseltamivir, coupled with th...
An acetamido cyclohexene that is a structural homolog of SIALIC ACID and inhibits NEURAMINIDASE.
Species of the genus INFLUENZAVIRUS B that cause HUMAN INFLUENZA and other diseases primarily in humans. Antigenic variation is less extensive than in type A viruses (INFLUENZA A VIRUS) and consequently there is no basis for distinct subtypes or variants. Epidemics are less likely than with INFLUENZA A VIRUS and there have been no pandemics. Previously only found in humans, Influenza B virus has been isolated from seals which may constitute the animal reservoir from which humans are exposed.
Membrane glycoproteins from influenza viruses which are involved in hemagglutination, virus attachment, and envelope fusion. Fourteen distinct subtypes of HA glycoproteins and nine of NA glycoproteins have been identified from INFLUENZA A VIRUS; no subtypes have been identified for Influenza B or Influenza C viruses.
Infection of domestic and wild fowl and other BIRDS with INFLUENZA A VIRUS. Avian influenza usually does not sicken birds, but can be highly pathogenic and fatal in domestic POULTRY.
A genus of the family ORTHOMYXOVIRIDAE comprising viruses similar to types A and B but less common, more stable, more homogeneous, and lacking the neuraminidase protein. They have not been associated with epidemics but may cause mild influenza. Influenza C virus is the type species.

Nephrology - kidney function
Nephrology is a specialty of medicine and pediatrics that concerns itself with the study of normal kidney function, kidney problems, the treatment of kidney problems and renal replacement therapy (dialysis and kidney transplantation). Systemic conditions...
