histamine receptor

The two known histamine receptors had already inspired hugely successful drugs.

It also produces additional actions which appear to be independent of histamine receptors.

For example, there are two types of histamine receptor: H1 and H2.

Experiments in 1983 suggested the existence of third, undiscovered histamine receptor.

Cimetidine is in a group of drugs called histamine receptor antagonists.

Silenor may help with sleep maintenance by blocking histamine receptors.

Antihistamines may increase hunger because histamine receptors are thought to play a role in appetite.

The four histamine receptors that have been discovered are designated H1 through H4.

H1 and H2 receptor (histamine receptors) blocking medications can also be given with some success.

Schwartz concluded he must have discovered a new histamine receptor, the H3 receptor.

There are several substances that have antihistaminergic action despite not being ligands for the histamine receptor.

Such effects may be blocked by administration of histamine receptor antagonists, such as cimetidine.

By blocking histamine receptors, antihistamines prevent these symptoms.

Once released, histamine can react with local or widespread tissues through histamine receptors.

It is a H1 histamine receptor antagonist.

From these facts the SK&F scientists postulated the existence of two histamine receptors.

There are four known histamine receptors:

Histamine exerts its actions by combining with specific cellular histamine receptors.

Antihistamines competitively bind to histamine receptor sites, thus reducing the neurotransmitter's effects.

However mirtazapine's strong antagonism of the histamine receptor can result in sedation, and the drug often causes significant weight gain.

When substances were discovered which did block these actions a second histamine receptor was postulated and the search began for clinically acceptable drugs.

The antihistamines act on the histamine receptors in the vomiting center and on vestibular afferents.

Levocetirizine works by blocking histamine receptors.

Classically, antihistamines (H1 histamine receptor antagonists) produce sleep.
