Type And Benefits of Antihistamines
Histamine H1 receptor antagonist
Clinically used to treat allergies. Examples of vine is: difenhidramina, loratadina, desloratadina, meclizine, quetiapine (an antihistamine nutritional side effects of antipsychotic medication), and prometazina.
Histamine H2 receptor antagonist
H2 histamine receptors found in the parietal cells. Performance is improving gastric acid secretion. Thus H2 receptor antagonists (H2 antihistamines) can be used to reduce gastric acid secretion, and can also be used to deal with peptic ulcer and reflux disease gastroesofagus. Examples of vine is simetidina, famotidina, ranitidina, nizatidina, roxatidina, and lafutidina.
Histamine H3 receptor antagonist
H3 antagonists have benefits as a stimulant and strengthens cognitive ability. Its use is being studied to treat Alzheimer‘s disease, and schizophrenia. Examples of vine is ciproxifan, and clobenpropit.

Immunomodulator evenly, being examined usefulness as an anti-inflammatory and analgesic. Examples are tioperamida.
Several other drugs also have antihistamine benefits. Examples are tricyclic antidepressants and antipsychotic drugs. Prometazina is a drug originally intended as an antipsychotic, but is now used as an antihistamine. Other compounds such as compound-cromoglicate and nedocromil, can prevent release of histamine by stabilizing mast cells, thereby preventing the degranulation.
