Primarily the antibiotics-the group drugs intended to inhibit or destroy bacteria, should be used only against bacterial infection. The antibiotic Norfloxacin is prescribed for treating bacterial infections, including urinary tract infections, prostatitis, and gonorrhea infections of the urethra or cervix. This antibiotic works to kill bacteria by interfering
with specific enzymes, which prevents the bacteria from multiplying. When taking an antibiotic, it is important to keep the amount of the bloodstream fairly constant. If the amount gets too low, they can begin to regrow. If the amount gets too high, it could cause other Complications. In this paper, a dynamical model has been constructed to find the amount
of the Norfloxacin in the blood stream.
