About Principen
Principen contains ampicillin, a common antibiotic indicated for the treatment of various bacterial infection types. Penbritin is another well-known brand name for this active substance, representing a staple in clinical practice. Principen is supplied as a tablet in 250mg and 500mg strengths, often produced by manufacturers such as Bristol-Myers Squibb.
Principen availability in Asia
Principen is registered across 14 markets including Thailand, Malaysia and the Philippines, with availability also in Indonesia, Taiwan and South Korea. Generic ampicillin, much of it manufactured in India, is frequently more affordable than the original brand for expats living in regions with limited medical stocks. As with all antibiotics, this medication is best utilised under the care of a doctor to manage a bacterial infection properly.
