Ceiling prices restrict market negotiations by setting maximum prices purchasers can pay for drugs
Reference prices use local or international price comparisons of drugs classified in a group as therapeutically similar to determine a single or maximum price for all drugs in that group
Profit limits control how much profit a drug manufacturer may earn per product or within a specified period of time.
