Research Excerpts

Effects

ExcerptReferenceRelevance
"Ritalinic acid has further been detected in German rivers at concentrations of 4-23 ngL(-1) and in bank filtrate samples in 100-850 m distance from the river up to 5 ngL(-1) demonstrating the widespread occurrence of this stable metabolite in the aquatic environment."( Occurrence and fate of the human pharmaceutical metabolite ritalinic acid in the aquatic system.
Letzel, M; Schüssler, W; Sengl, M; Weiss, K, 2010

Pharmacokinetics

Methylphenidate concentrations were not markedly affected by ethanol, but ritalinic acid concentrations were lower. For the first time a physiologically based pharmacokinetic (PBPK) model has been developed.
