4.3 Indication of immediate medical attention and special treatment needed, if necessary
Absorption, Distribution and Excretion
The percutaneous absorption has been investigated in rats of a mixture (3:2, w/w) of N-methyl-2-pyrrolidinone and 2-pyrrolidinone, a combination intended for use as a vehicle in the formulation of an antimycotic drug to enhance skin penetration on dermal application, following co-administration of the two (14)C-radiolabelled compounds by the dermal and oral routes. Radioactivity was excreted predominantly in the urine after either route of administration, and comparison of the respective excretion profiles indicated that about three-quarters of the applied dose was absorbed through the skin. Plasma concentrations of each parent compound, as determined by radio-HPLC, reached peak values at 2 hr after oral dosing, and remained relatively uniform during 1-6 hr after application to the skin, suggesting constant percutaneous absorption during this period. N-Methyl-2-pyrrolidinone appeared to be absorbed through the skin more extensively and at a slightly faster rate than 2-pyrrolidinone; total percutaneous absorption tended to be more extensive in female than in male rats. Together, these two 14C-compounds accounted for most of the plasma radioactivity up to 6-8 hr post-administration. However, by 12 hr (when plasma levels were relatively low), most of the radioactivity was associated with unknown polar metabolites. In view of the extensive percutaneous absorption and little first-pass metabolism of the two pyrrolidinones, the oral route was considered to represent a valid alternative to the dermal route for the assessment of the systemic toxicity of the two compounds.

12.3 Bioaccumulative potential
An estimated BCF of 3 was calculated for 2-pyrrolidone(SRC), using a log Kow of -0.85(1) and a regression-derived equation(2). According to a classification scheme(3), this BCF suggests the potential for bioconcentration in aquatic organisms is low.
12.4 Mobility in soil
Using a structure estimation method based on molecular connectivity indices(1), the Koc for 2-pyrrolidone can be estimated to be about 17(SRC). According to a classification scheme(2), this estimated Koc value suggests that 2-pyrrolidone is expected to have very high mobility in soil.
