Due to the pandemic, the monthly and year-to-date sales development is compared with sales in 2019 for increased transparency. As such, an increase of 11% in September 2021 total product sales was achieved in all markets compared to September 2019. In the USA, product sales increased by about 14% compared to September 2019. In September 2021, product sales were down by around 6% in Germany, while product sales in the remaining European markets increased by approximately 42% compared to September 2019.

Compared to product sales in 2019, year-to-date product revenues across all markets were back to pre-pandemic levels in 2021, despite the US business in particular still being severely impacted by the pandemic in the first few months of the year. Year-to-date product sales in 2021 increased by around 22% in Germany and by 16% in the rest of the European market compared to the same period in 2019. Product revenue in the US market was down 9%, mainly due to the weak sales months of January and February this year due to the pandemic as well as the lack of or lower sales of Aktipak® and Xepi® compared to the period January to September 2019.
