Dopamine receptor antagonist
Anaesthesia in great apes (Hominidae)
engineered mice lacking the dopamine transporter (DAT), modafinil lacked wake-promoting activity, suggesting that this activity was DAT-dependent. However, the wake-promoting effects of modafinil, unlike those of amphetamine, were not antagonized by the dopamine receptor antagonist haloperidol in …

studies using SPECT imaging have found that the NMDA antagonist ketamine (effect: reduces glutamate levels) enhances amphetamine-induced dopamine release in humans experiments with rats have looked at the role of NMDA antagonists and found a slight impact on dopamine release of dopamine, replicated in other laboratories.

Droperidol is an butyrophenone, a potent dopamine receptor antagonist and related to acepromazine (both major tranquilizers). Droperidol potentiates the ventilatory response to hypoxia, and its use in combination with an opioid reduces the dose of anaesthetic agents required for induction and, therefore, decreases the potential for respiratory depression (Kearns et al., 2000).

The antagonist [B] and agonist [D] are competing for the same limited number of receptors [R]. The drug that binds to the receptor in the highest concentration will be determined by two factors. These factors are the affinities of the agonist and antagonist for the receptor and their relative concentrations.

1st generation H1 receptor antagonist, all inverse agonists--because all H-receptors display baseline activity, these prevent any binding to receptors and reduce baseline activity. Sedating, used as adjunctive in anaphylaxis (H2 antag and Epinephrine also used), …

Tramadol has many reported pharmacological actions—it is a μ opioid receptor agonist, a 5HT reuptake inhibitor and releaser, a noradrenaline reuptake inhibitor, an NMDA receptor antagonist, a 5HT 2C receptor antagonist, a nicotinic acetylcholine receptor antagonist; some of these actions mediate its beneficial and adverse effects.

8) There are clear structural similarities between dopamine and noradrenaline. For that reason, it it is possible that dopamine has similar binding interactions with its receptor. Taking this argument further, strategies that led to antagonists for adrenergic receptors might also work in finding antagonists for the dopamine receptor.
