Pharmaceutical variation
Pharmaceutical variation does occur, specific examples including lithium, nifedipine and diltiazem.
A prime example of this was phenytoin in Australia, where the manufacturer changed the excipient from CaSO4 to lactose, which resulted in a huge increase in plasma phenytoin levels, and some deaths.
