Miljöpåverkan
Ganirelix
Miljörisk:
Risk för miljöpåverkan av ganirelix kan inte uteslutas då ekotoxikologiska data saknas.
Nedbrytning:
Det kan inte uteslutas att ganirelix är persistent, då data saknas.
Bioackumulering:
Ganirelix har hög potential att bioackumuleras.

Environmental Risk Classification
Predicted Environmental Concentration (PEC)
PEC is calculated according to the following formula:
PEC (μg/L) = (A*109*(100-R))/(365*P*V*D*100) = 1.5*10-6*A(100-R)
PEC = 3.2 x 10-6 μg/L
Where:
A = 0.021 kg (total sold amount API in Sweden year 2019, data from IQVIA) (Ref. I)
R = 0 % removal rate (worst case assumption)
P = number of inhabitants in Sweden = 9 *106
V (L/day) = volume of wastewater per capita and day = 200 (ECHA default) (Ref. II)
D = factor for dilution of waste water by surface water flow = 10 (ECHA default) (Ref. II)
Predicted No Effect Concentration (PNEC)
Ecotoxicological studies
No ecotoxicology studies are available for ganirelix and no PNEC can be determined.
Justification of chosen environmental risk phrase:
No data are available, therefore the phrase chosen for ganirelix is “Risk of environmental impact of ganirelix cannot be excluded, since no ecotoxicity data are available”.
According to the European Medicines Agency guideline on environmental risk assessment of medicinal products (EMA/CHMP/SWP/4447/00), use of ganirelix is unlikely to represent a risk for the environment, because the predicted environmental concentration (PEC) is below the action limit 0.01 μg/L.
Degradation studies
No degradation data are available for ganirelix.
Justification of chosen degradation phrase:
No data are available, therefore the phrase chosen for ganirelix is “The potential for persistence of ganirelix cannot be excluded, due to lack of data”.
Bioaccumulation
Estimated Log P = 5.4 (Computed by XLogP3 3.0 (PubChem release 2019.06.18)) (Ref. III)
Justification of chosen bioaccumulation phrase:
Since the estimated Log P > 4, the phrase chosen is “Ganirelix has high potential for bioaccumulation”.
