Abstract
Antihistamines are the first-line treatment for allergic diseases. The optimization of pharmacological properties of these pharmacotherapeutics is provided by the synthesis of new molecules with better safety profile (no penetration via the blood-brain barrier or less risk of drug interactions) or more selective affinity to H1-receptors (active optical isomer). In real clinical practice, drugs with extrahepatic metabolism have an advantage, the effectiveness of which does not depend on concomitant therapy, and the maximum concentration is reached in the shortest possible time, which ensures a rapid onset of action. Comfort use and, therefore, adherence to treatment is also an essential aspect of pharmacotherapy. Current orodispersible H1-receptor antagonists have a clinically significant antihistamine effect and agree with patient expectations due to comfort use and no need to take them with water. As a result, these medications are suitable for specific categories of individuals, e.g., children, patients with difficulty of swallowing, and people practicing an active lifestyle.
