Penicillin class antibiotics, including Amoxicillin, do not kill bacteria but prevent bacteria from forming walls that surround them, which are necessary for bacteria to multiply and survive.. Reverse Transcriptase is an enzyme that forms part of the reproduction process of the HIV virus. Nitrofurantoin interferes with the production of proteins, DNA, and cell walls in the bacterial cells. Lamivudine is converted within the body to its active form, Lamivudine Triphosphate, which is similar to a chemical, Deoxycytidine Triphosphate, that is used by Reverse Transcriptase to make new DNA. It can also be used alone or in combination with other antibiotics to treat abscesses in the liver, pelvis, abdomen and brain caused by susceptible anaerobic bacteria. The Reverse Transcriptase enzyme uses Stavudine Triphosphate instead of Thymidine Triphosphate for making DNA and this interferes with the reverse transcriptase. The Reverse Transcriptase enzyme uses Lamivudine Triphosphate instead of Deoxycytidine Triphosphate and this interferes with the reverse transcriptase. However, Efavirenz does not kill existing HIV virus and it is not a cure for HIV. Valacyclovir nitrofurantoin inhibits the replication of viral DNA which is necessary for viruses to reproduce themselves.

Acyclovir reduces the pain and the number of lesions in the initial case of genital herpes, and decreases the frequency and severity of recurrent infections. Clindamycin is used in the treatment of lung infections, skin infections, septicemia, abdominal infections, blood infections, internal organ infections and vaginal infections. This medication is also an effective treatment against Hepatitis B. Reverse Transcriptase is the enzyme that the virus uses to form this new DNA. Acyclovir can be used to treat chicken pox and acts to reduce healing time, limit the number of lesions generic sustiva and reduce fever. Nevirapine prevents Reverse Transcriptase from working properly and infecting healthy cells, thus slowing down the progress of the virus. Efavirenz is directly inhibits the activity of Reverse Transcriptase and blocks the production of DNA and new viruses. In the treatment of shingles, acyclovir reduces pain, shortens the healing time, and limits the spread of virus and the formation zovirax (brand) of new lesions.

Metronidazole works by selectively blocking some of the functions within the bacterial cells and the parasites resulting in their death. Lamivudine belongs to class of drugs called Nucleoside Reverse Transcriptase ciprofloxacin Inhibitors. Stavudine is converted within the body to its active form, Stavudine Triphosphate, which is similar to Thymidine Triphosphate, a chemical that is required by the HIV virus to make new DNA. Amoxicillin can only treat bacterial infections and is effective against viral infections. Reverse transcriptase is the enzyme that the virus lamivudine uses to form new DNA for infecting other cells. Doxycycline works by works by interrupting the production of proteins by bacteria and is commonly used for the treatment of Rocky Mountain spotted fever, fevers from ticks, typhus, rickettsial pox, urinary tract infections, acne, gonorrhea, chlamydia, periodontitis (gum disease), uncomplicated rectal infections, cervical infections and sexually transmitted infections like non gonococcal urethritis. Combivir (Lamivudine 150mg and Zidovudine 300mg) belongs to the class of Nucleoside Reverse Transcriptase Inhibitors (NRTIs).

Azithromycin is effective against susceptible bacteria causing ear infections, tonsillitis, laryngitis, bronchitis, pneumonia, sinusitis and several sexually transmitted infectious diseases. Combivir prevents reverse transcriptase from working properly and infecting healthy cells and thus slows down the progress of the HIV virus by preventing it from infecting healthy cells. Ciprofloxacin is used to treat generic valtrex infections in the skin, lungs, airways, bones & joints, urinary tract and diarrhea. Nevirapine is not a cure for HIV and cannot help cells that have already been infected with the virus. Ciprofloxacin belongs to the Fluoroquinolone class of antibiotics which inhibit the reproduction and repair of the genetic material of bacteria and thus stop the spread of bacterial infection. Clindamycin works by stopping the growth of bacteria by preventing the production of important proteins necessary for the survival of bacterial cells. Stavudine does not kill existing HIV virus and it is not a cure for HIV. Reverse transcriptase forms part of the reproduction process of the HIV virus and is responsible generic viramune for infecting cells and spreading the virus. Metronidazole is used in the treatment of Giardia infections of the small intestine, amebic liver abscesses, amebic dysentery bacterial vaginosis and trichomonas vaginal infections. Bactrim is used to treat bacterial infections, such as ear infections, bronchitis, urinary tract infections, traveler's diarrhea and Pneumocystis Pneumonia.
