Limits on Price Increases for Essential Drugs

This bill sets rules to prevent drug companies from raising prices too much on essential drugs and requires them to provide information about costs if the price goes up significantly.

What This Bill Does

  • Defines 'essential off-patent or generic drugs' as prescription medicines that treat serious health conditions, have limited competition in the market, and are actively manufactured by three or fewer companies.
  • Prohibits drug manufacturers and wholesale distributors from engaging in price gouging on essential drugs unless the increase is due to higher costs passed down by another manufacturer.
  • Requires the state medical assistance program to notify the attorney general if an essential drug's price increases by 50% within a year, under certain conditions.
  • Allows the attorney general to request information from manufacturers about why prices increased and take legal action against companies that violate these rules.

Who It Names or Affects

  • Drug manufacturers and wholesale distributors of essential drugs.
  • Consumers who rely on essential drugs for their health.
  • The state medical assistance program, which helps pay for healthcare costs.

Terms To Know

Price gouging
An unconscionable increase in the price of a prescription drug that is excessive and not justified by production or distribution costs.
Wholesale acquisition cost
The price paid by wholesalers for drugs before they are sold to pharmacies or hospitals, as defined in 42 United States Code section 1395w-3a.

Limits and Unknowns

  • It is unclear how the bill will be enforced and what specific actions drug companies might take in response.
  • The effectiveness of the bill depends on whether manufacturers comply with requests for information about price increases.
  • The bill does not specify an effective date, so it's uncertain when these rules would start applying.

A. The state medical assistance
program may notify the attorney general of any increase in the price of an
