Normally, I’m all for getting out the torches and pitchforks for pharma companies, but there are some other considerations when it comes to penicillins. Due to the prevalence and severity of penicillin allergies, penicillin drugs basically have to be made in facilities dedicated to just that to avoid cross-contamination. If they used any of the same equipment (even packaging equipment) there would be too high a risk of causing allergic reactions via contamination of other medications, and there would be no way to tell which ones are contaminated.
The fix to this problem is to spread out the licensing and allow more companies to produce penicillins in appropriate facilities as opposed to leaving it in the hands of a single conglomerate.
