Description:

Acrivastine (usually 8mg three times daily) is an effective and well tolerated antihistamine in the treatment of chronic urticaria and allergic rhinitis. Acrivastine is more effective than placebo and similar in efficacy to clemastine or terfenadine in the treatment of seasonal allergic rhinitis. In the treatment of dermatoses in which histamine has a pathogenetic role, the efficacy of acrivastine is superior to that of placebo and similar to that of usual dosages of clemastine, hydroxyzine, chlorpheniramine, cyproheptadine or terfenadine. Acrivastine causes less drowsiness than clemastine, the incidence of adverse effects being indistinguishable from that with placebo or terfenadine. Both 4 mg and 8 mg acrivastine alleviate the symptoms of seasonal allergic rhinitis with significant improvements in the symptom scores for sneezing, running nose and the calculated overall score. In addition, 8 mg acrivastine reduces the symptom scores for watery eyes and itchy throat. Acrivastine is both well tolerated and effective in the treatment of seasonal allergic rhinitis.

Cat. No.	Product name	Field of application
DC46842	Cipralisant maleate	Cipralisant (GT-2331) (maleate) is an orally active, low-toxicity, potent, selective, high affinity histamine H3 receptor full antagonist in vivo, and an agonist in vitro, with a pKi of 9.9 for histamine H3 receptor and a Ki of 0.47 nM for rat histamine H3 receptor. Cipralisant (maleate) has the potential for attention-deficit hyperactivity disorder research.
DC46433	JNJ-39758979 dihydrochloride	JNJ-39758979 dihydrochloride is a selective, orally active, and high-affinity histamine H4 receptor antagonist, with Kis of 12.5, 5.3, and 25 nM for human, mouse, and monkey histamine H4 receptor, respectively. JNJ-39758979 dihydrochloride functionally antagonizes histamine-induced cAMP inhibition with a pA2 of 7.9 in transfected cells. JNJ-39758979 dihydrochloride shows good anti-inflammatory and antipruritic activity.
DC45797	Methapyrilene hydrochloride	Methapyrilene (Thenylpyramine) hydrochloride is an orally active H1-receptor antihistamine and an anticholinergic agent of the pyridine chemical class. Methapyrilene hydrochloride has hepatotoxicity and can be used as a hepatotoxin that cause periportal hepatic necrosis in vivo
DC45376	(Z)-Lafutidine	(Z)-Lafutidine ((Z)-FRG-8813) is a potent histamine H2 receptor antagonist. (Z)-Lafutidine shows anti-secretory and gastroprotective activities.
DC44555	Promethazine	Promethazine is a potent histamine H1 receptor antagonist. Promethazine is a medication used in the management and treatment of allergic conditions, nausea and vomiting, motion sickness, and sedation. Promethazine exhibits antiparasitic properties.
DC44554	Levocetirizine	Levocetirizine (LCZ, (R)-Cetirizine), the R-enantiomer of cetirizine, is an antagonist of histamine H(1) receptor.
DC42500	Levocabastine hydrochloride	Levocabastine hydrochloride is a long acting, highly potent and selective histamine H1-receptor antagonist with anti-allergic activity. Levocabastine hydrochloride is also a selective, high affinity neurotensin receptor subtype 2 (NTR2) antagonist, with a Ki of 17 nM for mNTR2.
DC42309	Betazole	Betazole (Ametazole), a pyrazole analogue of histamine, is an orally active H2 receptor agonist. Betazole induces gastric acid secretion, and causes an immediate and significant increase in common bile duct pressure. Betazole has been used as a diagnostic agent known as histalog, for investigating gastric acid secretory capacity.
DC41413	Psoralenoside	Psoralenoside is a benzofuran glycoside from Psoralea corylifolia. Psoralenoside exhibits high binding affinities against histaminergic H1, calmodulin, and voltage-gated L-type calcium channels (E-value≥-6.5 Kcal/mol). Psoralenoside?shows estrogen-like activity, osteoblastic proliferation accelerating activity, antitumor effects and antibacterial activity.
DC41275	Betahistine mesylate	Betahistine mesylate is an orally active histamine H1 receptor agonist and a H3 receptor antagonist. Betahistine mesylate is used for the study of rheumatoid arthritis (RA).
