Toladryl is a derivative of Diphenhydramine (HY-B0303), capable of penetrating the blood-brain barrier and possessing oral activity, as well as antihistamine and anticholinergic activities. The anticholinergic activity of Toladryl is approximately one-tenth that of Diphenhydramine (HY-B0303), and its protective effect against lethal doses of histamine in guinea pigs is 2 to 4 times that of Diphenhydramine (HY-B0303). The side effects of Toladryl are fewer and milder than those of Diphenhydramine (HY-B0303), but at higher doses, it may cause central nervous system symptoms such as insomnia, agitation, and disorientation. Toladryl can be used for research in allergic diseases .

Mequitamium iodide (LG 30435) is an antihistamine drug with antiallergic and bronchodilatory activity. Mequitamium iodide can effectively antagonize airway contraction and inflammatory responses induced by histamine and antigens. Mequitamium iodide has nanomolar affinity for the H1 and smooth muscle receptors of histamine and mequitin. Mequitamium iodide, when administered in aerosol form, significantly inhibits histamine- and antigen-induced increases in airway pressure in allergic mice. Mequitamium iodide reduces antigen-induced eosinophil accumulation in the airways. Mequitamium iodide also exhibits inhibitory effects on PAF-induced platelet aggregation and bronchoconstriction, and can be used in the study of allergic diseases such as rhinitis and asthma .
