What are antivirals?
antivirals are very strong medicines that kill viruses and prevent them from growth and spread. They are often used against Epstein-Barr, a virus of human immunodeficiency (HIV), cytomegalovirus and herpes. Antivirals are also used to combat the flu, including H1N1 or pig flu.
It is more difficult to develop drugs to combat viral infections because viruses live inside cells in the body. Many times the immune system cannot detect and fight these infections. Serious viral infections such as HIV and serious cases of influenza are often fatal. Antivirals can help treat patients with some viruses and help others with fatal diseases such as HIV, live longer and better life. Most antivirol are administered orally in a pill, tablet or liquid form or as an inhalation drug. Hospitalized patients often receive antiviral drugs intravenously via IV line, which allows the drug to enter the fastest.
These drugs are most effective when they are administered shortly after the patient becomes illOr a viral infection is diagnosed. Although antivirols do not cure a majority of viruses, they can speed up the recovery process and cause the symptoms to be less severe. Sometimes antiviral drugs are administered to people who are not ill if they have been or are exposed to a person with a highly contagious viral infection such as the flu. About 70 to 90 percent of people who take antivirols to prevent influenza.
The most common side effects of antiviral drugs are gastrointestinal problems, cavity and headache problems. Most antiviral drugs are safe for use in children and pregnant women. Children, pregnant women and elderly people can very much benefit from antiviral drugs because they have a higher risk of serious symptoms and complications of an infection.
Some viruses are resistant to antiviral drugs, allowing further research and development of drugs necessary to create and discover new drugs KTEThey can fight them effectively. Many countries supply antivirals, so they have enough to treat the people who need the most, and those who are most at risk of pandemic.
Antiviral drugs administered for acute health conditions such as influenza are usually used for five to seven days to improve symptoms and reduce the course of the disease. Patients with chronic conditions who do not have treatment can be on the antivirals of the moon, years or even permanently to help them reduce symptoms and improve the quality of life. Individuals with chronic conditions such as HIV and Herpes may need their antiviral drugs and doses regularly to gain maximum advantage, as viruses can quickly adapt and become resistant to drugs.
