ReviewOA

作者: Luss, L V

Histamine that belongs to one of the most important mediators involved in the regulation of the body's vital functions plays a great role in the pathogenesis of different diseases. Histamine is released during inflammatory and allergic reactions, anaphylactic and anaphylactoid shock, pseudoallergic reactions, and others. Acting through histamine receptors, it leads to increased intracellular concentration of cyclic guanosine monophosphate, enhanced chemotaxis of eosinophils and neutrophils, production of prostaglandins and thromboxane B, suppressed synthesis of lymphokines, etc. and causes contraction of smooth muscles of particularly the bronchi and intestine, dilation of vessels and their increased permeability, mucus hypersecretion in the upper airways, lower blood pressure, angioedema and itch, etc. In this connection, antihistamines that block histamine-induced reactions in various ways: by inhibiting its biosynthesis, enhancing its neutralization, blocking the access to receptors, and suppressing the release from mast cells, occupy a prominent place in clinical practice. The review covers the classification, main mechanisms of pharmacological action, and indications for the use of antihistamines that not only have the well-known antihistamine properties, but have also a broad spectrum of anti-inflammatory activity. There are data on the benefits of a group of antihistamines, the quinuclidine derivatives (quifenadine, sequifenadine) that were designed by Academician M.D. Mashkovsky and are one of the first examples of designing new classes of multifunctional non-sedating antihistamines, which combines a high selective activity to block histamine type 1 receptors and an ability to block serotonin and to break down histamine directly in tissues.

Despite evolving success of mini-invasive techniques in treating cardiac arrhythmias in children, pharmaceuticals remain the cornerstone therapeutic option. Beyond conventional antiarrhythmic agents such as amiodarone, local anesthetics, tranquilizers, anticonvulsants, and neuroleptics exhibit antiarrhythmic properties. H(1)-histamine receptor blockers are widely used in treating allergies in children. Observational studies suggest efficacy of these agents for treating or preventing tachyarrhythmias, although prolongation of QT interval, and ventricular arrhythmias occur. We determined safety and efficacy of antihistamine, quifenadine, versus conventional amiodarone on cardiac rhythm in children with frequent premature beats (PB). One hundred and four patients (mean age 10.8 +/- 3.2 years) with ventricular (n = 65), supraventricular (n = 39) PB were randomized 1:1 to quifenadine (2 mg kg(-1) day(-1); n = 54), or amiodarone (9 mg kg(-1) day(-1), n = 50) arms. Both groups were treated for 2 weeks. All patients underwent 24-hour Holter monitoring 3 times: before at 14-28 days after randomization, and during the follow up at 2-3 months. The mean frequency of PB in quifenadine group was 562 +/- 61 per hour and 597 +/- 78 per hour in the amiodarone-treated children. Full antiarrhythmic efficacy (PB < 75% from baseline) has been achieved in 23/54 (43%) of quifenadine-treated patients, which was less than after amiodarone treatment (37/50, 74%, P = 0.02). Quifenadine was mostly beneficial in children with supraventricular PB and/or bradycardia than in those with ventricular PB; it was associated with a trend toward increased heart rate during day (88.5 +/- 8.4 beats/min) and night (67.3 +/- 6.2) compared with amiodarone (79.6 +/- 7.8 and 56.1 +/- 5.7 beats/min, respectively; P = 0.04). The incidence of side effects in quifenadine group (drowsiness and headache) was low (2%) in contrast to the alarming 40% risk associated with amiodarone therapy. Quifanidine exhibits antiarrhythmic activity in children with frequent PB, without significant QT prolongation, or sinus node depression. Although, H(1)-histamine receptor blocker is less potent than amiodarone, much better safety profile of quifenadine is advantageous, especially in children. Future large trials with proving novel antihistamines pleiotropy are warranted.

[The effect of antihistamine preparations on the contraction of the isolated guinea pig ureter].

Article

作者: Kaminka, M E ; Zhirnikova, M L

The effect of antihistaminics on contractions of the isolated guinea pig ureter was studied. The ureter contractions induced by histamine were prevented by H1-blockers: pipolphen (promethazine), dimedrol (diphenhydramine), phencarol (quifenadine), suprastin (chloropyramine), cyproheptadine and H2-blockers: cimetidine, ranitidine. Electric stimulation-induced contractions were prevented by suprastin. Phencarol, tavegil, cimetidine, ranitidine didn't act on the contractions. The electrically induced contractions were potentiated by pipolphen, dimedrol, cyproheptadine.
