Which is True about dobutamine?: (A) Dobutamine decreases peripheral resistance, (B) Acts on D1 and D2 receptors, (C) Decrease kidney circulation, (D) Has no effect on coronary circulation
Answer is A. Ref: HL Sharma 3rd ed pg no: 177 Dobutamine is a derivative of dopamine and is a selective beta1 agonist. It causes an increase in the force of contraction without a significant increase in hea rate. It also produces some vasodilatation by stimulating the beta 2 receptors. It doesn't decrease kidney circulation.
