Which drugs appear to produce therapeutic effects by blocking receptor sites for dopamine?
antipsychotics
What are the effects of dopamine receptor antagonists?
They inhibit the expression of dopamine.
What other drugs can be used in place of reglan?
Reglan is a dopamine receptor antagonist. So, if you want to use it for its anti-emetic effects, other dopamine receptor antagonists will work. These include Domperidone, Olanzapine, and haloperidol. However, if you're using reglan for its effect on lactation, domperidone is the other choice.
What part of the brain does anti-psychotics work?
Anti psychotic medication is used to treat schizophrenia, bipolar disorder, and various other conditions. It works by blocking dopamine receptors in the brain, meaning that the effects of dopamine are lessened.
What parts of brain do the neurolyptics effect?
The theory behind why individuals develop 'psychotic' symptoms is based upon the idea that there are elevated levels of dopamine in the brain. Dopamine is a neurotransmitter, a molecule that passes messages between neurons. For example, when a nerve impulse arrives at a dopaminergic neuron (also known as a pre-synaptic neuron), dopamine is released from the cell and diffuses through a space between two neurons, called the synaptic cleft. Dopamine then binds to specific dopamine receptors on a different neuron (post-synaptic neuron) producing a specific signal, impulse or effect. Dopamine is then released from its receptors and 're-absorbed' into the pre-synaptic neuron, or degraded by enzymes in the synaptic cleft. The neuroleptics block dopamine receptors thereby inhibiting the ability of dopamine to attach to these receptors and generate signals. However, unlike the typical neuroleptics, the atypicals merely transiently block the receptors therefore allowing some dopamine to bind to the receptors and generate signals. The atypical neuroleptics are also able to block serotonin receptors located on dopaminergic neurons. When serotonin binds to these receptors it inhibits dopamine release. However as these receptors are blocked by atypical neuroleptics, the dopamine secretion is increased. The transient rather than permanent blocking of dopamine receptors and the blocking of serotonin receptors and subsequent increases in dopamine, it is for these reasons that the atypicals are thought to produce fewer adverse effects than the typical neuroleptics. However, the atypical drugs differ in their 'stickyess' when binding to dopamine receptors and also in the ratio of which dopamine ad serotonin receptors are affected. This may result in some atypicals producing higher levels of specific adverse effects than others. The atypicals may also bind to other receptor types, producing further adverse effects (see side effects of atypicals section).
Why are neurotransmitters affected by ecstasy?
LSD mainly affects the Cerebral Cortex. LSD is a serotonin receptor agonist and much of its hallucinogenic effects are thought to result from binding to the 5-HT2A serotonin receptor in particular. LSD also affects all subtypes of dopamine receptor and all subtypes of adrenoreceptor.
Would hurting myself increase dopamine Like small cuts or burns Pain releases dopamine right?
No, self harm has not been shown to cause effects on the dopamine/reward system nor on the opioid-receptor system. It may have an an effect on the serotonin system, but this is not shown in any established study. Any imagined relief from psychic problems resulting in self-harm is almost certainly is psychic.
What is dopamine used for?
Dopamine is the major neurotransmitter of the reward circuit in the central nervous system. It also functions in movement and balance, among other things. It is a chemical found in the human brain that creates feelings of pleasure.
What is high bloodpressur?
Micardis is a blood pressure medication of the type known as angiotensin receptor blockers (or ARB's). Angiotensin is a chemical that the body produces to raise blood pressure and these drugs work by blocking their effects.
What is micardis high bloodpressure?
Micardis is a blood pressure medication of the type known as angiotensin receptor blockers (or ARB's). Angiotensin is a chemical that the body produces to raise blood pressure and these drugs work by blocking their effects.
What are the therapeutic effects of laughter?

How does a substance such as Methamphetamines produce its effects?
The "substance" binds itself to the dopamine receptors and tricks the brain into believing it is receiving messages from dopamine.
