Every drug with addiction potential increases DA, either through direct or indirect effects on DA neurons in the ventraltegmentalarea(VTA)withtheconsequentreleaseof DA in the nucleus accumbens (NAc) (357) (FIGURE 1).

For example, cocaine acts by binding to the dopamine transporter, blocking the removal of dopamine from the synapse. Dopamine then

Dopamine (also referred to as 3 hydroxytyramine) is a naturally occurring endogenous catecholamine. Dopamine hydrochloride injection is a clear, practically colorless, sterile, pyrogen-free, aqueous solution of dopamine HCl for intravenous infusion after dilution. Each milliliter of the 40 mg/mL preparation contains.

Background—A “renal dose” of dopamine is often used to increase renal blood flow; however, data on the magnitude of effect and site of action in patients with heart failure are scarce. Methods and Results—Renal effects of intravenous dopamine (1, 2, 3, 5, and 10 g · kg 1 · min 1) were evaluated in 13 patients with chronic heart failure.

Mechanism of Action Most antipsychotic drugs bind to D 2 dopamine receptors and block the action of dopamine (Fig. 9-1). However, drug bind-ing to the receptors does not account for antipsychotic effects because binding occurs within a few hours after a drug dose, and antipsychotic effects may not occur until the drugs have been given for a few ...

This drug-induced parkinsonism strongly suggested that antipsychotic drugs were interfering with dopamine pathways in the human brain, because Parkin- son 's disease was known to be a disease of insufficient dopa- mine neurotransmission. This clinical observation gave birth to the dopamine hypothesis of psychosis and antipsychotic drug action (3).
