By: Salius Pharma Allergic rhinitis is a symptomatic disorder and an IgE-mediated inflammatory response of the nasal membranes induced by allergen exposure. It is an allergic condition like asthma, where the body tends to over react to certain types of outside substances. In one way it overreacts by producing antibodies that signal your immune system to release histamine and other chemicals. The symptoms include rhinorrhoea, nasal obstruction, nasal itching and sneezing of the nose, coughing, tearing of the eyes, sore throat, wheezing and headache. It affects social life, sleep, school and as a whole the quality of life of patients gets impaired. Asthma is linked with allergies, heredity and environment. In a normal person various airborne allergens (triggers) induce the production of antibodies and other chemicals in controlled quantity, which destroy the allergen but don’t harm the body. But in allergic individual who have asthma there is over production of antibodies and other chemicals which causes inflammation of the airways, cough, wheezing, dyspnoea, airflow obstruction, tendency towards allergic disease like eczema, allergic rhinitis, allergic conjunctivitis. All of us like to lead a comfortable life. However, a life with asthma keeps us bothering about how to manage the burden of asthma attack.

Montelukast sodium is an orally active compound that binds with high affinity and selectivity to the Cysteinyl Leukotriene (CysLT1) receptor. Levocetirizine, the R-enantiomer of cetirizine, is a potent, selective and long acting H1 -histamine receptor antagonist with no anticholinergic activity. INDICATIONS:- CROHIST–MK & CROHIST-MK KID is indicated for the treatment of Allergic Rhinitis (Seasonal and Perennial) and in the chronic treatment of Asthma.

PHARMACOKINETICS Montelukast Absorption Montelukast is rapidly absorbed orally and the mean oral bioavailability is 64%. Distribution Montelukast is bound to plasma proteins more than 99%. The steady-state volume of distribution of Montelukast averages about 8 to 11 litres. Metabolism Montelukast is extensively metabolized and plasma concentrations are undetectable at steady state in adults and pediatric patients. Elimination Montelukast and its metabolites are excreted almost exclusively through the bile. Levocetirizine Absorption Levocetirizine is rapidly and extensively absorbed following oral administration. Peak plasma concentrations are achieved 0.9 g h after dosing. Distribution Levocetirizine is widely distributed and 90% bound to plasma proteins. Biotransformation The extent of metabolism of Levocetirizine in humans is less than 14% of the dose. Metabolic pathways include aromatic oxidation, N- and O-dealkylation and taurine conjugation. CONTRAINDICATIONS: Patients those who are hypersensitive to Montelukast, Levocetirizine, Piperazine derivatives or to any other components of the formulation and renal impaired patients are not supposed to take this medication. WARNINGS AND PRECAUTIONS Montelukast Eosinophilic conditions Some patients on treatment with Montelukast may show symptoms of eosinophilia, presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome, a disease condition, which is often treated with systemic corticosteroid therapy. Levocetirizine It is recommended not to use in patients who has eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, etc. DRUG INTERACTIONS Montelukast: Phenobarbital, which induces hepatic metabolism, decreased the AUC of Montelukast approximately 40% following a single 10-mg dose of Montelukast. Levocetirizine: In sensitive patients the simultaneous administration of cetirizine or Levocetirizine and alcohol or other CNS depressants may have effects on the central nervous system. Pregnancy This combination should not be used during pregnancy since no well-controlled studies of either Montelukast or Levocetirizine have been conducted in pregnant women.
