👉 Infections occur when pathogens, such as bacteria, viruses, fungi, or parasites, invade the body and multiply, causing damage to tissues and organs. The body's immune system responds by mounting an inflammatory reaction to combat these invaders. However, certain drugs can either directly target the pathogens or enhance the immune response to fight infections more effectively. Antibiotics are a class of drugs that specifically kill or inhibit the growth of bacteria, while antivirals target viruses by disrupting their replication processes. Antifungal medications combat fungal infections, and antiparasitic drugs eliminate parasites. In some cases, drugs like corticosteroids may be used to reduce inflammation and modulate the immune response, preventing excessive damage. Understanding the mechanisms of these drugs is crucial for treating infections effectively while minimizing side effects and resistance development.
