(Armodafinil, NCI Thesaurus)

In addition, both enantiomers of carvedilol bind to and block alpha 1-adrenergic receptors, thereby causing vasodilation and reducing peripheral vascular resistance.

(Carvedilol phosphate, NCI Thesaurus)

The R-enantiomer of the calcium channel blocker verapamil.

(Dexverapamil, NCI Thesaurus)

The oxalate salt of escitalopram, a pure S-enantiomer of the racemic bicyclic phthalane derivative citalopram, with antidepressant activity.

A synthetic antihypertensive methoxyphenoxy- 2-propanol derivative with no intrinsic sympathomimetic activity, Carvedilol acts as a nonselective beta-adrenoceptor blocking agent (S(-) enantiomer) and as an alpha 1-adrenoceptor blocker (R(+) and S(-) enantiomers).

(Carvedilol, NCI Thesaurus)

Carvedilol is a racemic mixture; the S(-) enantiomer non-selectively binds to and blocks beta-adrenergic receptors, exerting negative inotropic and chronotropic effects, leading to a reduction in cardiac output.

(Carvedilol Phosphate Extended-Release Capsule, NCI Thesaurus)

The S enantiomer of carvedilol nonselectively binds to and blocks beta-adrenergic receptors, thereby exerting negative inotropic and chronotropic effects, and leading to a reduction in cardiac output.
