Results Of the three nicotinic receptor agonists tested, [3H]cytisine displayed the highest affinity for the neu- ronal nicotinic receptor (Table 1). It had a significantly higher affinity of 0.145 + 0.011 nM (P < 0.05, Fig. 1A) as compared to KD values of 0.89 + 0.06 and 1.07 _+ 0.13 nM for [3H]nicotine (Fig.
Cetirizine /sÉËtÉªrÉ¨ziËn/ (trade names Zirtec, Zyrtec, Reactine) is a second-generation antihistamine used in the treatment of hay fever, allergies, angioedema, and urticaria.It is a major metabolite of hydroxyzine, and a racemic selective H1 receptor antagonist.llergies [edit].
