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

Predicted Environmental Concentration (PEC)
PEC is calculated according to the following formula:
PEC (µg/L) |
= |
(A*109*(100-R))/(365*P*V*D*100) = 1.37*10-6*A*(100-R) |
PEC |
= |
0.0000340521 μg/L |
Where: |
|
|
A |
= |
0.24855572 kg (total sold amount API in the most recent sales data for Sweden (2020) was distributed by IQVIA in 2021) |
R |
= |
X % removal rate (due to loss by adsorption to sludge particles, by volatilization, hydrolysis or biodegradation) = 0 if no data is available. |
P |
= |
number of inhabitants in Sweden = 10 *106 |
V (L/day) |
= |
volume of wastewater per capita and day = 200 (ECHA default) (Ref. 1) |
D |
= |
factor for dilution of wastewater by surface water flow = 10 (ECHA default) (Ref. 1) |
According to the European Medicines Agency guideline on environmental risk assessment of medicinal products (EMA/CHMP/SWP/4447/00), use of Miglustat is unlikely to represent a risk for the environment, because the predicted environmental concentration (PEC) at the time of registration was below the action limit 0.01 μg/L.
Predicted No Effect Concentration (PNEC)
Ecotoxicological studies
No data available.
Environmental risk classification (PEC/PNEC ratio)
Calculation of Predicted No Effect Concentration (PNEC)
No data available.
Environmental risk classification (PEC/PNEC ratio)
Conclusion for environmental risk:
Risk of environmental impact of Miglustat cannot be excluded, since no ecotoxicity data are available.
DEGRADATION
Biotic degradation
Ready biodegradation
No data available.
Conclusion for degradation:
The potential for persistence of Miglustat cannot be excluded, due to lack of data.
