The first generic for Viagra® (sildenafil) was launched to wholesalers and pharmacies in the United States. Sildenafil is a phosphodiesterase-5 (PDE-5) inhibitor used to treat erectile dysfunction, available in 25, 50, and 100mg tablets. Erectile dysfunction can be an adverse effect of opioid utilization. Treatment for this condition may be prescribed to injured workers using opioids for chronic pain. Due to patent lawsuit settlements, the generic manufacturer, Teva, can market its generics with 180 days of exclusivity – meaning that no other company may produce generics until after this time, giving Teva the full share of this drug’s generic market for six months. Pfizer, the manufacturer of brand name Viagra, is also releasing an authorized generic through its Greenstone generics division. Additional generics are expected to enter the U.S. market on June 9, 2018. Other PDE-5 inhibitors approved for treating erectile dysfunction include Cialis® (tadalafil – Lilly) and Levitra® (vardenafil – Bayer/GlaxoSmithKline). Generics for Cialis will become available September 27, 2018, and Levitra’s brand name patent is expected to expire on October 31, 2018. Additionally, while progress is not known, Pfizer and Lilly/Sanofi have previously expressed interest in attempting to make Viagra and Cialis, respectively, available without a prescription.
