Three major groups of antibiotics are described below.
Cephalosporin
Cephalosporin interferes with synthesis of bacterial cell wall and so is bactericidal.
Cephalosporins are used to treat pneumonia, sore throat, tonsillitis, bronchitis etc.
Tetracycline
These are broad-spectrum bacteriostatic antibiotics and inhibit bacterial protein synthesis. Tetracycline is used in the treatment of infections of respiratory tract, urinary tract, intestine etc. Tetracyclines are not used in children under the age of 8, and specifically during periods of tooth development.
Sulpha Drugs-Sulphonamides
Sulpha drugs are synthetic antibiotics that contain sulphonamide group. Sulphonamides are broad spectrum bacteriostatic antibiotics. They inhibit the folic acid synthesis in bacteria. They are used to treat pneumonia and urinary tract infections.
