Clinical Summary

A GUANOSINE analog that acts as an antimetabolite. Viruses are especially susceptible. Used especially against herpes.

Therapeutic Applications

Acyclovir is used to treat infections caused by certain types of viruses. It treats cold sores around the mouth (caused by herpes simplex), shingles (caused by herpes zoster), and chickenpox. This medication is also used to treat outbreaks of genital herpes. In people with frequent outbreaks, acyclovir is used to help reduce the number of future episodes. Acyclovir is an antiviral drug. However, it is not a cure for these infections. The viruses that cause these infections continue to live in the body even between outbreaks. Acyclovir decreases the severity and length of these outbreaks. It helps the sores heal faster, keeps new sores from forming, and decreases pain/itching. This medication may also help reduce how long pain remains after the sores heal. In addition, in people with a weakened immune system, acyclovir can decrease the risk of the virus spreading to other parts of the body and causing serious infections.

Clinical Summary

An aminoglycoside, broad-spectrum antibiotic produced by Streptomyces tenebrarius. It is effective against gram-negative bacteria, especially the PSEUDOMONAS species. It is a 10% component of the antibiotic complex, NEBRAMYCIN, produced by the same species.

Therapeutic Applications

This medication is used to treat people with a certain inherited condition (cystic fibrosis) who have an ongoing lung infection with a certain bacteria (Pseudomonas aeruginosa). People with cystic fibrosis produce thick, sticky mucus that can plug up the tubes, ducts and passageways in the lungs. This can result in serious breathing problems and infections in the lungs. Tobramycin belongs to a class of drugs known as aminoglycoside antibiotics. Tobramycin inhalation solution works by stopping the growth of a certain bacteria (Pseudomonas aeruginosa) that commonly infects the lungs of people with cystic fibrosis.
