Miljöpåverkan
Plerixafor
Miljörisk:
Risk för miljöpåverkan av plerixafor kan inte uteslutas då ekotoxikologiska data saknas.
Nedbrytning:
Det kan inte uteslutas att plerixafor är persistent, då data saknas.
Bioackumulering:
Plerixafor har låg 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) = 1.37*10-6*A*(100-R)
PEC = 7.40*10-7 μg/l
Where:
A = 0.0054 kg (total sold amount API in Sweden year 2022, data from IQVIA)
R = 0% removal rate (due to loss by adsorption to sludge particles, by volatilization, hydrolysis or biodegradation)
P = number of inhabitants in Sweden = 10*106
V (l/day) = volume of wastewater per capita and day = 200 (ECHA default) (Ref I)
D = factor of dilution of waste water by surface water flow = 10 (ECHA default) (Ref I)
Predicted No Effect Concentration (PNEC)
Ecotoxicological studies
No ecotoxicity data available.
Environmental Risk Rlassification (PEC/PNEC ratio)
The PEC/PNEC ratio could not be calculated since no ecotoxicity results are available, hence justifying the phrase: "Risk of environmental impact of plerixafor 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 plerixafor 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
No data available, therefore the degradation phrase should be: "The potential for persistence of plerixafor cannot be excluded, due to lack of data."
Bioaccumulation
Partitioning coefficient:
Log Kow = 0.94 at pH 7 (OECD 107) (Ref II)
Justification of chosen bioaccumulation phrase: Since log Kow < 4 at pH 7, plerixafor has low potential for bioaccumulation.
Excretion (metabolism)
In healthy subjects (0.24 mg/kg) approximately 70% of the parent drug is excreted in urine in the first 24 hours. Metabolism does not involved CYP isoenzymes. (Ref III).
The pharmacological activity of possible metabolites is not known.
