Levocetirizine like cetirizine, has a potential anti-inflammatory effect in the treatment of allergic rhinitis with asthma. Levocetirizine (structure I A) is the levo rotatory enantiomer of cetirizine. Patients to enjoy an improved quality of life.Ĭetirizine has an asymmetric center in the molecule and thus may exist as optical isomers (enantiomers). Generation allergy drugs diminish the commonly experienced sedative effect and allow Non-sedatingĬharacter of cetirizine is an important breakthrough in allergy treatment because new Provide a positive impact on patients who have experienced activity impairment fromĪllergies thereby significantly improving health related quality of life. Safe and effective, symptomatic relief of seasonal allergies.
Studies have shown that cetirizine provides Generation of HI histamine receptor antagonists, which are believed to offer significantĪdvantages over first generation compounds. This mitigates theĪbility of histamine to promote allergy symptoms. Antihistamines such as cetirizine block theĮffect of histamines that are released by allergic reactions in the body. Cetirizine is orally active lc.g-Īcting histamine HI receptor antagonist. Treatment of allergies including but not limited to chronic and acute allergic rhinitis,Īllergic conjunctivitis, pruritus, urticaria and the like.
This is evidenced by the increased levels of antibodies developed in response to environmental allergic factors such as dust mites pets and air pollutants.Ĭetirizine and its salts, including dihydrochloride is known and is effective in the There has been a significant increase in the number of reported allergic conditions over the last three decades. Methyl]-1- Piperazinyl] Ethoxy] Acetic Acid Dihydrochloride
The following specification describes the nature of this invention and the manner in which it is to be performed:Ī Method Of Preparation Of Levorotatory [2-[4-[(4-ChIorophenyI)-PhenyI A METHOD OF PREPARATION 0* LEVOROTATORY -1- PIPERAZINYL] ETHOXY] ACETIC ACID DIHYDROCHLORIDE.
