Antagonists
Antagonists are the drugs not possessing or having very weak true activity, counteracting agonists, preventing their access to receptors (as, for example, Naloxonum).
Other bunch of opioids which invoke the circumscribed reactions of particulate receptor phylum even at introduction in high doses, name particulate agonists.
Joint introduction of particulate and full agonists reduces effect of action of full agonists.
There are antagonists of opium receptors who unequally influence various receptors. Such drugs can react simultaneously as agonists concerning one receptor, and as antagonists – concerning other receptors. Similar drugs name agonists-antagonists or the admixed agonists-antagonists.
