Which medication is often prescribed for bacterial infections?

Aureomycin is an antibiotic that is specifically used to treat bacterial infections. It belongs to the tetracycline class of antibiotics and works by inhibiting bacterial protein synthesis, thereby stopping the growth of bacteria. This makes it effective against a variety of infections caused by susceptible bacteria, highlighting the importance of antibiotics in managing bacterial diseases.

In contrast, morphine is an opioid analgesic designed for pain relief and has no antibacterial properties. Navacaine, a local anesthetic, is used to block sensation in specific areas during procedures, while cocaine, though it has historical use as a local anesthetic, is primarily known for its recreational use and potential for abuse. None of these medications are appropriate for treating bacterial infections, which solidifies Aureomycin's role as the suitable choice in this context.
