Description

Esoxybutynin is (S)-enantiomer of oxybutynin. Esoxybutynin exerts antimuscarinic properties. Racemic oxybutynin is used clinically to treat urinary incontinence. Sepracor was developing (S)-oxybutynin, a single-isomer version of Alza's Ditropan (racemic oxybutynin), a muscarinic acetylcholine receptor antagonist, as a potential treatment for urinary incontinence.

Route of Administration: Oral
In Vitro Use Guide
Membrane currents were recorded from whole-cell configured guinea-pig and rabbit ventricular myocytes, and action potentials were recorded from guinea-pig and rabbit papillary muscles. L-type Ca(2+) current (I:(Ca,L)), rapidly-activating K(+) current (I:(Kr)) and slowly-activating K(+) current (I:(Ks)) were unaffected by submicromolar S-oxybutynin and inhibited by higher concentrations; IC(50) values were 17.8 microM for I:(Ca,L), 12 microM for I:(Kr), and 41 microM for I:(Ks).
