Specialty Pharmacy 5© 2021 Omnicell, Inc. Content is confidential and proprietary. Macro Trends Over 50% of current drug spend is in specialty pharmaceuticals.1 Specialty medications account for 75 percent of the approximately 7,000 prescription drugs currently in development, and nearly two- thirds of the 600 drugs expected to win FDA approval by 2022 are specialty medications.2 Providing specialty pharmacy services is often more complex and differentiated from traditional health system pharmacy operations. Expertise and systems are needed to effectively implement and operate a specialty pharmacy program. Many health systems have not yet implemented a specialty pharmacy program, or it is sub-optimized. Specialty Pharmacy is a key part of a comprehensive medication management platform and an important part of the Autonomous Pharmacy vision. 1.
