Pharmacies used to make drugs themselves in larger scale decades ago, but industrial manufacturing drove over it. It's not common any more for a pharmacy to make drugs, because it's not profitable.
Still it is allowed though. There is nothing against a pharmacy to own drug manufacturing capacity or both having same ownership.
Besides mr. Odidi is a pharmacist if I recall it right. It would fit him well. Maybe much better than the present position, where he seem not to perform extremely good.
Mopar made a calculation for possible Focalin sales. It would not have high volume sales because definitely 10% of children do not have Focalin medication. Not even 1%. But make the same calculation for metformin. Every single type II diabetic has this medication on, and there are tens of millions of those patients. The number is even growing every year.
An insurance does prohibit generic substitution. The cheaper cure the better for insurance company. Generic drugs are sold in high volume. They would not be if insurance did not allow them to be sold.
