Dobutamine

The pharmacological effects of dobutamine (see Table 10-1 for structure) result from direct interactions with a and b receptors and are complex. The preparation of dobutamine used clinically is a racemate. The (-) isomer of dobutamine is a potent a1 agonist and pressor; (+) dobutamine is a potent a1 antagonist that can block the effects of (-) dobutamine. Both isomers are full agonists at b receptors, but the (+) isomer is more potent than the (-) isomer by -tenfold.
