Bromocriptine use in the puerperium has been associated with an increased risk of serious thromboembolic events. It is an ergot alkaloid derivative in the dopamine D2 agonist class of drugs. Like all ergopeptides, bromocriptine is a cyclol; two peptide groups of its tripeptide moiety are crosslinked, forming the >N-C(OH)< juncture between the two rings with the amide functionality. Mechanism of Action of Bromocriptine Bromocriptine is a dopaminergic agonist. It also exhibits agonist activity (in order of decreasing binding affinity) on 5-hydroxytryptamine (5-HT)1D, dopamine D3, 5-HT1A, 5-HT2A, 5-HT1B, and 5-HT2C receptors, antagonist activity on α2A-adrenergic, α2C, α2B, and dopamine D1 receptors, partial agonist activity at receptor 5-HT2B, and inactivates dopamine D4 and 5-HT7 receptors. The serum concentration of Bromocriptine can be increased when it is combined with Abametapir. However, the pathways of either dopamine or its agonists that lead to the death of cells are incompletely understood and some are even conflicting conclusions. The hallucinogenic side effects of dopamine agonists may also be due to 5-HT2A agonism. 2009 Feb;75(2):374-80. doi: 10.1124/mol.108.052084. Decreases in intracellular calcium levels may also be brought about via inhibition of calcium influx through voltage-gated calcium channels, rather than via inhibition of adenylyl cyclase. 2008;8(12):1049-67.
