============================================
New in this version:

• Search results and drug listings now clarify which listed drugs are reference listed drugs (RLDs) and which are reference standards.

Orange Book Express allows you to:

• Search by Active Ingredient or Proprietary Name; Applicant Holder (Firm); Application Number; or Patent Number.
• Search all marketing statuses (Rx, OTC, Discontinued) with one search.
• Look up patent and exclusivity information.
• Identify Reference Listed Drugs (RLDs) and determine if a drug product has a therapeutic equivalent.
