Hazard - P - B - T - Risk Low
Fass environmental information for Captopril Actavis (captopril) from Teva (downloaded 2019-12-04).
Persistence: No data.
Bioaccumulation: No data.
Toxicity: No data.
Risk of environmental impact of captopril cannot be excluded, since no ecotoxicity data are available.
Comment. Manufacturer has on fass.se stated that data is missing for the substance so that the environmental risk cannot be calculated. It is voluntary for manufacturers to provide information on the environmental impact on fass.se.
Comparative environmental risk assessment using angiotensin converting enzyme (ACE) inhibitors enalapril, ramipril, lisinopril and captopril from a Swedish perspective (Report Goodpoint 2019).
ACE inhibitors are sold in large quantities but all the compared substances (except ramipril) and active metabolites are very water soluble with very low potential to accumulate in aquatic biota to levels that are considered to pose a risk. For ramipril, there is a certain risk that the substance reaches the environment and bioconcentrates in biota sufficiently to cause a pharmacological effect. However, there is no bioconcentration data for the substances. Available toxicity tests indicate low toxicity to aquatic organisms, but they are acute tests and are not designed to address the specific effects of ACE inhibitors.
Although the environmental risk is highest for ramipril, the overall evidence for environmental risk is still low. No exchanges for environmental reasons are therefore recommended. More research on ramipril and its potential for bioconcentration and toxicity (chronic and mechanism-based) is desirable.
