Eli Lilly and Company’s (LLY) human pharmaceutical segment includes neuroscience products Cymbalta, Strattera, Prozac, and Zyprexa. Overall sales for neuroscience products fell in 4Q17 due to lower Strattera, Prozac, and Zyprexa sales, and were partially offset by strong Cymbalta sales.

Cymbalta, an antidepressant drug, generated revenue of $192.8 million in 4Q17, marking 6.0% growth from the $181.8 million reported in 4Q16.
