Dopaminergic means "related to dopamine" (literally, "working on dopamine"), dopamine being a common neurotransmitter. Dopaminergic substances or actions increase dopamine-related activity in the brain. Dopaminergic brain structures facilitate dopamine-related activity. For example, certain proteins such as the dopamine transporter (DAT), vesicular monoamine transporter 2 (VMAT₂), and dopamine receptors can be classified as dopaminergic, and neurons that synthesize or contain dopamine and synapses with dopamine receptors in them may also be labeled as dopaminergic. Enzymes that regulate the biosynthesis or metabolism of dopamine such as aromatic L-amino acid decarboxylase or DOPA decarboxylase, monoamine oxidase (MAO), and catechol O-methyl transferase (COMT) may be referred to as dopaminergic as well. Also, any endogenous or exogenous chemical substance that acts to affect dopamine receptors or dopamine release through indirect actions (for example, on neurons that synapse onto neurons that release dopamine or express dopamine receptors) can also be said to have dopaminergic effects, two prominent examples being opioids, which enhance dopamine release indirectly in the reward pathways, and some substituted amphetamines, which enhance dopamine release directly by binding to and inhibiting VMAT₂.
Composition and Method for Treating Metabolic Disorders
Bromocriptine citrate administered to a vertebrate, animal or human, can be used for any purpose including, e.g., the long-term modification and regulation of metabolic disorders, including prediabetes, obesity, insulin resistance, hyperinsulinemia, hyperglycemia and type 2 diabetes mellitus (T2DM) and / or, e.g., the treatment of other medical disorder(s) including immune or endocrine disorders or diseases. Bromocriptine citrate is administered over a limited or extended period at a time of day dependent on re-establishing the normal circadian rhythm of central dopaminergic activity of healthy members of a similar species and sex. Insulin resistance, hyperinsulinemia and hyperglycemia, T2DM, prediabetes, MS or all, can be controlled in humans on a long term basis by such treatment inasmuch as the daily administration of bromocriptine citrate resets neuronal activity timing in the neural centers of the brain to produce long term effects.
