Voquenza is not a recognized medical term, however, based on the provided evidence, it appears that the question may be referring to oseltamivir, an antiviral medication used to treat influenza. The medication works by inhibiting the neuraminidase glycoprotein, which is essential for the replication of influenza A and B viruses 1. Oseltamivir is a prodrug that is converted to its active form, oseltamivir carboxylate, which then selectively inhibits the neuraminidase enzyme, preventing the release of new viral particles from infected cells 2. This mechanism of action reduces the duration and severity of influenza symptoms, and can also prevent the development of secondary complications such as pneumonia and bronchitis 3. In geriatric patients, oseltamivir has been shown to be effective in reducing mortality and complications associated with influenza, and is considered a first-line treatment option 4. However, it is essential to note that the effectiveness of oseltamivir can be influenced by factors such as the timing of treatment initiation, the severity of the infection, and the presence of underlying medical conditions 5. Some key points to consider when using oseltamivir include:
- The medication should be initiated as soon as possible after the onset of symptoms, ideally within 24-48 hours 3
- The recommended dosage is 75 mg twice daily for 5 days, although this may vary depending on the patient's age, weight, and renal function 1
- Oseltamivir can be used for both treatment and prevention of influenza, and is effective against both influenza A and B viruses 2
- Common side effects include nausea, vomiting, and diarrhea, although these are generally mild and transient 1
