Sildenafil sales?

Do you mean:

- Global sales for sildenafil (including generic versions) in a specific period, or
- Pfizer’s branded Viagra sales specifically, or
- The overall erectile-dysfunction drug market size?

If you can specify the time frame (e.g., 2023, 2024 year-to-date, last 5 years) and whether you want Pfizer-only or all sildenafil (brand + generics), I can give you more precise figures.

Here’s a quick, general context in the meantime:

- Sildenafil is the active ingredient in Viagra (Pfizer) and Revatio (for pulmonary arterial hypertension). Since the expiration of many patents, generic sildenafil has become widely available in many markets.
- Because of generic competition, branded Viagra sales have declined in some regions, but the drug remains widely used. The total global market for sildenafil (brand + generics) has historically been in the low-to-mid billions of dollars per year, with regional variations and year-to-year changes driven by pricing, patent status in each market, and uptake of other PDE5 inhibitors.
- The erectile-dysfunction drug market also includes competitors like Cialis (tadalafil) and Levitra/Stendra, so regional market shares shift by brand.

If you want exact numbers, tell me the timeframe and whether you want Pfizer-only or the global sildenafil market, and I can pull the most relevant figures or guide you to the best sources.
