Adefovir is converted intracellularly in stages to the di-phosphate, which then inhibits the DNA synthesis of hepatitis B virus through competitive inhibition of reverse transcriptase and incorporation into viral DNA. At high doses it has some activity against HIV.
Abacavir is converted intracellularly in stages to its active form carbovir triphosphate. This halts the DNA synthesis of retroviruses, including HIV, through competitive inhibition of reverse transcriptase and incorporation into viral DNA.
What are the primary causes of chronic bronchitis? What is the difference between emphysema and chronic bronchitis? What are the most common symptoms of chronic bronchitis? How do I know when to get help from a health care professional? How serious is chronic bronchitis?
When you visit your healthcare professional, he or she will ask you about your symptoms before diagnosing the condition and conducting any tests. Are you coughing up mucus? Do you smoke cigarettes? Do you have difficulty breathing? Does your chest feel tight?
According to the American Lung Association, chronic bronchitis affects approximately 5.4 percent of the population, or 14.2 million people, in the United States. The condition has been slightly more prevalent in men than in women, but chronic bronchitis affects people of all ages. The highest incidence rate has been found in people over 50 years old.
Bronchitis is a form of lung disease that interferes with the lungs’ ability to move enough air in and out. In chronic bronchitis, the airways have become permanently swollen, which narrows them and may cause coughing and heavy mucus. This swelling in the airways is usually a response to irritants, such as tobacco smoke. Chronic bronchitis can lead to repeated lung infections.

Traditional antibiotic treatment for community-acquired pneumonia usually lasts from 10-14 days. Today, shorter courses of antibiotic therapy can be prescribed.
The elderly, infants and young children, and individuals with underlying health problems, such as chronic bronchitis, diabetes and congestive heart failure, are considered at high risk for pneumonia. People who have diseases that impair the immune system, such as AIDS, are especially susceptible to pneumonia.
Pneumonia is an inflammation of one or both of the lungs caused by a bacterial, viral or fungal infection. The word “community” means that the infection was not contracted while the patient was in the hospital.
