Annual US prescription sales hit $291 billion in 2008, but experienced slower-than usual growth of 1.3% because of slowing demand and the struggling economy, according to IMS Health, which also reported that dispensed prescription volume in the US grew at a 0.9% pace.
IMS Health reports that the lower growth rate was influenced by a number of factors:
- Higher demand for less-expensive generic drugs
- Lower new product sales
- Reduced overall consumer demand because of the economic downturn
