Doxycycline is a broad-spectrum antibiotic belonging to the tetracycline group and is widely used in clinical practice to treat a variety of bacterial infections. It acts by inhibiting bacterial protein synthesis, which prevents the growth and multiplication of bacteria. Doxycycline is effective against both Gram-positive and Gram-negative microorganisms, making it useful for respiratory tract infections, skin infections, acne, and sexually transmitted diseases. It is also commonly prescribed for malaria prophylaxis and the treatment of certain zoonotic and inflammatory conditions. Due to its good oral absorption, longer half-life, and overall tolerability, doxycycline remains an important and frequently used antimicrobial agent.
