  • Vad är miljöinformation?

Miljöinformation

Miljöpåverkan

Tenoxikam

Miljörisk: Risk för miljöpåverkan av tenoxikam kan inte uteslutas då ekotoxikologiska data saknas.
Nedbrytning: Det kan inte uteslutas att tenoxikam är persistent, då data saknas.
Bioackumulering: Tenoxikam 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) = 1.5*10-6*A(100-R)


PEC = 0,00096 μg/L


Where:

A = 6,4004 kg (total amount API of tenoxicam in Sweden year 2017, data from IQVIA ) (Ref. 1)

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

P = number of inhabitants in Sweden = 9*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 Tenoxicam 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 P of 2,40 (Ref. 3) indicates that Tenoxicam has low potential for bioaccumulation.


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


Excretion (metabolism)

Tenoxicam is almost completely metabolized, and only 0,5% is excreted as the unchanged substance through the urine. Up to two thirds of a given oral dose is excreted renally, mainly as the metabolite 5-hydroxytenoxicam, and the rest is excreted biliary. (Ref. 4)
