Principen is the brand name for a medication called Ampicillin. It is an antibiotic that belongs to the class of drugs known as penicillins. Ampicillin is primarily used to treat various bacterial infections.

Medicament is effective against a wide range of bacteria, including respiratory tract infections, urinary tract infections, skin and soft tissue infections, and certain types of gastrointestinal infections. It is also used in the prevention of certain bacterial infections before surgical procedures.

This medication is available in the form of capsules, tablets, or oral suspension and is typically taken orally. In some cases, it may also be administered intravenously for severe infections.

Ampicillin works by inhibiting the growth of bacteria and interfering with the formation of their cell walls. By targeting the bacterial cell wall, ampicillin weakens and kills the bacteria, helping to clear the infection.

Uses of Principen

Principen is principally used as a treatment against many gram- positive and gram- negative bacteria. It is a very potent drug against bacterial infections, but it does not work against viral infections like flu, common cold, etc.

One thing you must keep in mind is that if you use it unnecessarily, the effectiveness will decrease gradually.
