Use In Pregnancy & Lactation
No well controlled trials have been performed with either Montelukast or Cetirizine in women who are pregnant. Therefore use of MONTELUKAST + CETIRIZINE is not recommended in women who are pregnant. It is not known whether Montelukast or Cetirizine is excreted in breast milk. Therefore use of MONTELUKAST + CETIRIZINE is not recommended in women who are breast feeding.

Hypersensitivity: Hypersensitivity reactions manifest as urticaria and fixed drug eruptions have been reported with Cetirizine.
Sedation: CNS depression is the most common adverse effect of Cetirizine. The sedative effect can range from slight drowsiness to deep sleep.

Drug Interactions
Montelukast: Decreased AUC w/ phenobarb. CYP3A4 inducers eg, phenytoin, rifampicin (particularly in childn). Cetirizine: Increased serum conc w/ pilsicainide. Increased INR & severe epistaxis w/ long-term acenocoumarol.
In drug-interactions studies, the recommended clinical dose of montelukast did not have clinically important effects on the pharmacokinetics of the following drugs: theophylline, prednisone, prednisolone, oral contraceptives (ethinyl estradiol/ norethindrone 35/1), terfenadine, digoxin and warfarin. The area under the plasma concentration curve (AUC) for Montelukast was decreased approximately 40% in subjects with co-administration of phenobarbital. Since Montelukast is metabolised by CYP 3A4, caution should be exercised, particularly in children, when Montelukast is coadministered with inducers of CYP 3A4, such as phenytoin, phenobarbital and rifampicin. In vitro studies have shown that Montelukast is a potent inhibitor of CYP 2C8. However, data from a clinical drug-drug interaction study involving Montelukast and rosiglitazone (a probe substrate representative of drugs primarily metabolized by CYP 2C8) demonstrated that Montelukast does not inhibit CYP 2C8 in vivo. Therefore, Montelukast is not anticipated to markedly alter the metabolism of drugs metabolized by this enzyme (e.g., paclitaxel, rosiglitazone, and repaglinide).
Cetirizine: Some interactions are less likely with Cetirizine than with non-sedating antihistamines such as astemizole and terfenadine, since Cetirizine appears to have low hepatic metabolism and little arrhythmogenic potential.
Concomitant use of Cetirizine and pilsicainide may increase the serum concentration of both drugs which may lead to drug toxicities.
Anticoagulants: There has been a report of a raised INR and severe epistaxis in a patient after the addition of Cetirizine to long-term acenocoumarol.

Action
Alduet mechanism of action for pharmacodynamics and pharmacokinetics details.
Montelukast: The cysteinyl leukotrienes (LTC4, LTD4, and LTE4) are potent inflammatory eicosanoids released from various cells including mast cells and eosinophils. These important mediators bind to cysteinyl leukotriene receptors. Cysteinyl leukotrienes have been correlated with the pathophysiology of asthma and allergic rhinitis. In asthma, leukotriene-mediated effects include bronchoconstriction, mucous secretion, vascular permeability, and eosinophil recruitment. In allergic rhinitis, cysteinyl leukotrienes are released from the nasal mucosa after allergen exposure during both early- and late-phase reactions and are associated with symptoms of allergic rhinitis. Intranasal challenge with cysteinyl leukotrienes has been shown to increase nasal airway resistance and symptoms of nasal obstruction. Montelukast is an orally active compound which binds with high affinity and selectivity to the cysteinyl leukotriene type 1 receptor thereby preventing cysteinyl leukotrienes from exerting their effects.
Cetirizine: Cetirizine hydrochloride, a piperazine derivative and metabolite of hydroxyzine, is described as a non-sedating antihistamine which is long-acting and has some mast-cell stabilizing activity. It appears to have a low potential for drowsiness in usual doses and to be virtually free of antimuscarinic activity. It is a selective H1-antagonist with negligible effects on other receptors and so it is virtually free from anticholinergic and antiserotonin effects. Cetirizine inhibits the histamine-mediated "early" phase of the allergic reaction and also reduces the migration of inflammatory cells e.g., eosinophils and the release of mediators associated with the "late" allergic response.
Pharmacokinetics: Montelukast: Absorption: Montelukast is rapidly absorbed 2 to 4 hours following oral administration. Mean peak plasma concentration (Cmax) is achieved 3 hours (Tmax) after administration of a 10 mg dose in adults in the fasted state. The mean oral bioavailability is 64%. The oral bioavailability and Cmax are not influenced by a standard meal. Safety and efficacy were demonstrated in clinical trials where the 10-mg film-coated tablet was administered without regard to the timing of food ingestion. Cmax is achieved in 2 hours after administration of the 5 mg chewable tablet in adults in the fasted state. The mean oral bioavailability is 73% and is decreased to 63% by a standard meal.
