Abstract: Pharmaceutical products have contributed to improving the expectancy and quality of life of millions of patients and their role in our society is undisputed. However, many active pharmaceutical ingredients have been found in rivers, lakes, seas, drinking water and can cause damage to the environment and ecosystems. Environmental contamination is known to affect biodiversity and health. From a "One Health" perspective, human health is safeguarded by preserving the environment and ecosystems. Italy is at the forefront on the issue of protecting biodiversity, having included it among the fundamental principles of the Constitution. At the same time the European Commission launched the strategy to protect biodiversity by 2030. To map and limit the environmental effect of drugs, it has been proposed the topic of ecopharmacovigilance and eco-directed sustainable prescribing. It's in this context that this work on the ready biodegradability of a drug-based on loperamide and a medical device made of complex natural matrix, Lenodiar-Pediatric®, was carried out for the first time. The products, indicated to treat diarrhoea, were found to be readily biodegradable. For Lenodiar-Pediatric® the biodegradation isn't surprising, while for the drug-based on loperamide it was due to the degradation of excipients. Indeed, the UHPLC-qToF investigation highlighted that loperamide was present at the end of the test and is therefore potentially persistent in the environment, confirming the most relevant literature. In conclusion, therapeutic products made of natural complex matrix which efficacy and safety have been proven according to Evidence-Based Standards may play an important role in safeguarding biodiversity.
