Which group of drugs is effective against infections caused by bacteria?

The class of drugs that is effective against infections caused by bacteria is antibiotics. Antibiotics are specifically designed to kill or inhibit the growth of bacteria, making them essential in treating bacterial infections. They target various bacterial functions or structures, such as cell wall synthesis, protein synthesis, or DNA replication, which are critical for bacterial survival and reproduction.

In contrast, analgesics are primarily used to relieve pain but do not address the underlying infection. Antihistamines are used to alleviate allergic symptoms by blocking histamine receptors and are not effective against bacteria. Anti-inflammatories, while useful in reducing inflammation and relieving pain, also do not have antimicrobial properties. Hence, when it comes to treating bacterial infections, antibiotics are the appropriate choice and play a crucial role in healthcare.
