  • Vad är miljöinformation?

Miljöinformation

Miljöpåverkan

Dimenhydrinat

Miljörisk: Risk för miljöpåverkan av dimenhydrinat kan inte uteslutas då ekotoxikologiska data saknas.
Nedbrytning: Det kan inte uteslutas att dimenhydrinat är persistent, då data saknas.
Bioackumulering: Dimenhydrinat 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 = 0.0068 μg/L


Where:

A = 49,74 kg (total amount API of dimenhydrinate in Sweden year 2023, data from IQVIA). (Ref. 1)

R = removal rate = 0% (no data available)

P = number of inhabitants in Sweden =10*106

V (L/day) = volume of waste water per capita and day = 200 (ECHA default) (Ref. 2)

D = factor for dilution of waste water by surface water flow = 10 (ECHA default) (Ref. 2)


According to the European Medicines Agency guideline on environmental risk assessment of medicinal products (EMA/CHMP/SWP/4447/00), use of dimenhydrinate is unlikely to represent a risk for the environment, because the predicted environmental concentration (PEC) is below the action limit 0,01 μg/L.


Ecotoxicological studies

No ecotoxicological data available.


Degradation

No degradation data available.


Bioaccumulation

An estimated log Kow of -0.39 (unknown method) (Ref. 3) indicates that dimenhydrinate has low potential for bioaccumulation.


Log Kow < 4 which justifies use of the phrase “Dimenhydrinate has low potential for bioaccumulation”.


Excretion (metabolism)

Dimenhydrinate is excreted renally, but only 4-5% is unchanged diphenhydramine, while the rest is excreted as different metabolites. (Ref. 4)
