- Pharmaceutical manufacturing can lead to substantial discharges of active pharmaceutical ingredients into the environment, with local consequences to the environment and, in the case of antibiotics, potentially global implications in terms of increasing risks for resistance development. In this study, we used Swedish sales data for pharmaceuticals combined with data on the origin of the active ingredients to determine if price pressure and generic substitution are related to the estimated general environmental performance and the perceived corruption levels of the production countries. In line with the general perception, India was the largest producer of generics, while Europe and the USA dominated for branded products. We found that the price and environmental performance index of the production countries were linked, but that this relationship was largely explained by whether the product was original or generic. Although this relationship would allow buyers to select products that are more likely to originate from countries that, in general terms, have better pollution control, it lacks resolution. We conclude that to better allow consumers, hospitals and pharmacies to influence the environmental impact of their product choices, there is need for regulation as well as transparency in the production chain. To this end, emissions from manufacturing need to be measured, allowing for control and follow-up on industry commitments towards sustainable manufacturing of pharmaceuticals.

- The fallopian tube transports the gametes to the fertilization site and delivers the embryo to the uterus at the optimal time for implantation. Progesterone and the classical progesterone receptor are involved in regulating both tubal ciliary beating and muscular contractions, likely via both genomic and non-genomic actions.

- Asthma is commonly treated with inhalable glucocorticosteroids, including beclomethasone dipropionate (BDP). This is a synthetic prodrug which is metabolized to the more active monopropionate (BMP) and free beclomethasone in humans. To evaluate potential effects of residual drugs on fish, we conducted a 14 day flow-through exposure experiment with BDP and beclomethasone using rainbow trout, and analyzed effects on plasma glucose, hepatic glutathione and catalase activity together with water and body concentrations of the BDP, BMP and beclomethasone. We also analyzed hepatic gene expression in BDP-exposed fish by microarray and quantitative PCR. Beclomethasone (up to 0.65 μg/L) was not taken up in the fish while BDP (0.65 and 0.07 μg/L) resulted in accumulation of both beclomethasone, BMP and BDP in plasma, reaching levels up to those found in humans during therapy. Accordingly, exposure to 0.65 μg/L of BDP significantly increased blood glucose as well as oxidized glutathione levels and catalase activity in the liver. Exposure to beclomethasone or the low concentration of BDP had no effect on these endpoints. Both exposure concentrations of BDP resulted in significantly higher transcript abundance of phosphoenolpyruvate carboxykinase involved in gluconeogenesis, and of genes involved in immune responses. As only the rapidly metabolized prodrug was potent in fish, the environmental risks associated with the use of BDP are probably small. However, the observed physiological effects in fish of BDP at plasma concentrations known to affect human physiology provides valuable input to the development of read-across approaches in the identification of pharmaceuticals of environmental concern.
