In the 21st century, there seems to be a gargantuan increase in cases of common colds, fevers, skin conditions, and allergic reactions. Especially with so much dust around, the reactions to allergies have become much worse as compared to what it might have been several years ago.
Allergic reactions like sneezing, runny nose, itchiness, and even wheezing can cause a lot of issues in daily life, and to mitigate or control these challenges, pharmacists have manufactured combination therapies like the Montelukast Sodium and Levocetirizine hydrochloride tablets to achieve targeted success.
This article will cover a comprehensive guide on the composition, the benefits, uses, and much more.
Montelukast Sodium and Levocetirizine Hydrochloride Tablets
Montelukast Sodium and Levocetirizine Hydrochloride tablets are widely used as a combination medication tablet that aims to treat allergic conditions such as allergic rhinitis (nasal allergies), asthma, and chronic hives (urticaria). This is a dual-action combination therapy that leverages the medical effects of the montelukast, a leukotriene receptor antagonist, and levocetirizine, a second-generation antihistamine. The combination medication helps relieve symptoms caused by allergens and airway inflammation quite effectively.
Leukotriene Receptor Antagonist (LTRA) Vs Antihistamines
Leukotriene Receptor Antagonist (LTRA)
Leukotriene receptor antagonists, or LTRAS, are a particular type of medication that block the action of leukotrienes, which are inflammatory molecules that are present and involved in asthma and allergic reactions.
LTRAs help reduce this inflammation that appears in the airways and induce symptoms like coughing, wheezing, and shortness of breath. Montelukast and zafirlukast are some of the popular LTRAs.
Antihistamines
Antihistamines are a particular class of medication drugs that work to block the effects of histamine, a chemical that the body releases during allergic reactions. Antihistamines like levocetirizine and loratadine help relieve allergic symptoms like sneezing, an itchy, runny nose, and more.
Montelukast Sodium and Levocetirizine Hydrochloride Tablet: Mechanism
Montelukast Sodium
Montelukast Sodium belongs to the LTRAs class, and the Leukotrienes are inflammatory mediators that are released by the body in response to allergens like pollen, dust, and pet hair or dander. The result of these allergens normally causes airway inflammation, wheezing, nasal congestion, and asthma-like symptoms. Montelukast Sodium works by binding the CysLT1 receptor and thus helps manage the allergic reaction, and even prevents asthma.
Levocetirizine Hydrochloride
the Levocetirizine Hydrochloride belongs to the antihistamine class ‘Cetirizine’ but this form is a rather potent but minimally sedative tablet. As compared to the first-generation antihistamines, this type is not as sedating despite being highly effective and potent. Levocetirizine provides rapid relief from acute allergy symptoms, thus making it very effective and especially complementary to Montelukast’s anti-inflammatory action.
Montelukast Sodium and Levocetirizine Hydrochloride Combination
With the effects of montelukast and the potency of Levocetirizine, one gets a very high-quality medicine that targets two distinct pathways of the allergic reactions and effects. With the former, you get to address the leukotriene-mediated inflammation, and with the latter, you get to tackle your allergy-driven symptoms. This dual mechanism of action offers instant symptom relief, which overall leads to an enhanced quality of life. In fact, clinical studies have even shown that this combination tablet is more effective together than as a drug alone.
