CTZ, Cetirizine

Cetirizine's origins can be traced back to its creation in the 20th century representing a notable breakthrough in allergy treatment with antihistamines.

The development of cetirizine was driven by the desire for effective and less drowsy allergy medications, an aspect where it excelled.

As a second-generation antihistamine cetirizine brought about a change compared to its predecessors by reducing its impact, on the central nervous system thus minimizing sedative effects.

Cetirizine, which is a type of derivative has a unique molecular structure that gives it powerful antihistaminic properties without causing excessive sedation. The fact that cetirizine is hydrophilic adds to its safety profile as it minimally crosses the blood-brain barrier.
