neomütsiin
Neomütsiin is an aminoglycoside antibiotic used to treat bacterial infections. It is produced by the bacterium *Streptomyces fradiae*. Neomütsiin works by inhibiting bacterial protein synthesis, which is essential for bacterial growth and survival. It is typically administered topically to the skin or eyes, or orally to prevent or treat certain types of intestinal infections. Due to its significant toxicity when absorbed systemically, neomütsiin is rarely given by injection. Its primary uses include the treatment of superficial skin infections, such as impetigo, and as a component in ophthalmic preparations for eye infections. Orally, it is used to reduce the bacteria in the gut before surgery or to treat hepatic encephalopathy, a complication of liver disease. Common side effects of topical neomütsiin include skin rash, itching, and redness. Oral administration can lead to gastrointestinal upset. The risk of developing resistance to neomütsiin is a concern, necessitating its judicious use. It is not effective against fungal or viral infections.
