Doxycycline 100 mg tablet is a widely used antibiotic that prevents the growth of harmful bacterial cells by blocking the formation of the protective outer protein layer (cell wall) responsible for their growth and multiplication. It is classified as a broad-spectrum antibiotic, meaning it is effective against a wide variety of bacterial infections. Being a bacteriostatic antibiotic, it stops the growth and spread of bacteria but does not directly kill them.
