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

Environmental Risk Classification
Predicted Environmental Concentration (PEC)
PEC is based on following data:
PEC (µg/L) = (A*109*(100-R))/(365*P*V*D*100)
PEC (µg/L) = 1.37*10-6*A*(100-R)
A (kg/year) = total sold amount API in the most recent sales data for Sweden (2022).
R (%) = 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 waste water by surface water flow = 10 (ECHA default) (Ref.1)
(Note: The factor 109 converts the quantity used from kg to μg).
A = 0,4408 kg. The total sold amount of ponatinib hydrochloride in Sweden year 2019, data from Quintiles IQVIA (Ref.2)
R =0
PEC = 1.37 * 10-6 * 0,4408 *(100-0) = 0,00006039 µg/L
According to the European Medicines Agency guideline on environmental risk assessment of medicinal products (EMA/CHMP/SWP/4447/00), use of ponatinib is unlikely to represent a risk for the environment, because the predicted environmental concentration (PEC) is below the action limit 0.01 µg/L.
Predicted No Effect Concentration (PNEC)
The risk of environmental impact of ponatinib cannot be excluded, since no ecotoxicity data are available.
Degradation
The potential for persistence of ponatinib cannot be excluded, due to lack of data.
Bioaccumulation
Ponatinib has an estimated log Kow = 4,32. (Ref.3)
The Log Kow is thus >4, which indicates that “Ponatinib has high potential for bioaccumulation.”
