What Type of Medicine is Monteka?

Monteka is a specific trade name for a single-ingredient, prescription-only medication whose active substance is the chemically synthesized compound Montelukast sodium (INN). This medication is classified as a Leukotriene Receptor Antagonist (LTRA), a specific type of anti-asthmatic and antiallergic modifying agent.

Montelukast is clinically recognized for its systemic, oral activity, setting it apart from many inhaled respiratory therapies. Its pharmacological identity defines it as a non-steroidal agent that selectively inhibits the action of cysteinyl leukotrienes at the CysLT1 receptor.

Composition and Available Forms (Tablet, Chewable, Granule)

Monteka contains Montelukast as the sodium salt, delivered in solid forms intended for oral administration. The medicine is manufactured in various presentations, notably the flavored chewable tablet and the oral granule formulations. These diverse forms—tablet, chewable tablet, and granule—all deliver the same active substance and are designated for the oral route of administration, offering necessary flexibility, particularly for the pediatric patient group.

General Purpose as a Leukotriene Modifying Agent

The primary therapeutic purpose of Montelukast is to help reduce and prevent inflammatory reactions in the respiratory system by specifically targeting leukotrienes. By blocking these inflammatory mediators from binding to receptors in the airways, the drug helps inhibit associated physiological effects such as swelling and smooth muscle contraction.

This consistent, preventive mechanism allows the drug to function as a long-term control agent, contributing to the stabilization of chronic conditions where airway inflammation is a core pathological factor. This function positions Monteka as a foundational, non-acute therapy aimed at sustaining proper respiratory function by modifying the body's ongoing inflammatory response.

What side effects are possible with Monteka?

Possible Side Effects and Safety Information

The safety profile of Montelukast (Monteka) is documented based on clinical studies and post-marketing surveillance, classifying reported effects by frequency as consistent with regulatory standards.

Frequency-Classified Adverse Reactions

The most frequently reported adverse reaction is upper respiratory infection, classified as Very Common (occurring in at least 1 in 10 individuals). Effects classified as Common (at least 1 in 100 individuals) include headache, abdominal pain, fever, and gastrointestinal symptoms such as nausea, vomiting, and diarrhea. Additionally, rash and elevations in liver enzymes (ALT, AST) are listed as common.

Key Safety Warnings

Official labeling contains warnings regarding serious Neuropsychiatric Events, which have been reported across all age groups. These events include mood and behavior changes such as suicidal thoughts and behavior, aggression, agitation, depression, and sleep disturbances. Reports indicate these symptoms may persist or emerge even after treatment is stopped.

Very Rare reports also include systemic conditions such as Churg-Strauss syndrome (CSS), a vasculitic syndrome often seen in association with the reduction or withdrawal of oral corticosteroid therapy, and hepatitis (liver inflammation).

Safety Constraints and Considerations

Montelukast is indicated only for long-term control and prevention and must not be used to treat acute asthma attacks. For patients with aspirin-sensitive asthma, the regulatory constraint is that they must continue to avoid aspirin and other non-steroidal anti-inflammatory drugs (NSAIDs) while receiving this therapy. The chewable tablet formulation contains aspartame, a source of phenylalanine, which is a required consideration for individuals with phenylketonuria (PKU).

Overdose and Emergency Response

Overdose and When to Seek Help

The regulatory guidance for Monteka (Montelukast sodium) overdose emphasizes a response centered on supportive management, as no specific antidote is known. Official reports submitted to government health authorities describe a core set of clinical findings observed in overdose cases, involving both adult and pediatric patients.

Documented Clinical Manifestations

Overdose presentations documented in regulatory sources included a set of central nervous system and gastrointestinal findings:

  • Somnolence (drowsiness) and Headache
  • Psychomotor hyperactivity
  • Abdominal pain and Vomiting
  • Thirst

In the majority of these reports, the observed clinical and laboratory findings were consistent with the drug’s known safety profile, and severe or life-threatening outcomes were generally not described.

Required Emergency Action and Management

In the event of suspected overdosage, it is required to seek immediate medical attention. Because no specific pharmacological antidote exists, regulatory guidance mandates that treatment must consist of employing the usual supportive measures and continuous clinical monitoring of the patient’s status. Management may also include instituting symptomatic therapy and procedural steps, such as removing unabsorbed material from the gastrointestinal tract, if deemed clinically necessary.

Therapeutic Uses of Monteka

What Monteka Treats: Main Uses and Benefits

Monteka is a specialized controller medication generally used for the long-term management and prevention of chronic symptoms related to specific respiratory and allergic conditions. This medication is applied across three core therapeutic areas.


The primary therapeutic applications involve the long-term control of chronic asthma, the symptomatic relief of allergic rhinitis (both seasonal and perennial), and the prevention of exercise-induced breathing difficulty.

Chronic Asthma and Allergic Relief

Monteka is commonly prescribed for the daily management of symptoms associated with mild-to-moderate persistent asthma, playing a role in managing symptoms that create noticeable physiological strain, such as wheezing, chronic coughing, and chest tightness. It is also applied to address the symptomatic discomfort of allergic rhinitis, relevant for managing clusters of symptoms like nasal congestion and sneezing. This continuous, preventive support is relevant for easing the overall symptom load and may assist with maintaining functional stability.

“This medication is primarily used to help prevent symptoms, supporting the patient during difficult episodes and helping with participation in routine activities.”


Situational Prevention

A distinct application is the prevention of exercise-induced bronchoconstriction (EIB). Used before physical exertion, this generally provides a relevant situational benefit: it may assist with maintaining functional stability, supporting the patient during difficult episodes, and helping with participation in routine activities.

Quick Fact: Relief for Respiratory and Allergic Discomfort Monteka is commonly used to help patients manage symptoms that interfere with daily functioning across both the lower respiratory tract (asthma) and the upper respiratory tract (allergic rhinitis).

Prohibited Patients in acute distress Treatment of acute asthma attacks (must not be used).
Restricted Patients with PKU Must be advised that chewable tablets contain phenylalanine.

Age-Related Eligibility (Minimum Thresholds)

Official guidelines set differing minimum ages for use depending on the condition:

  • Chronic Asthma: Eligible for patients 12 months of age and older.
  • Perennial Allergic Rhinitis: Eligible for patients 6 months of age and older.
  • Exercise-Induced Bronchoconstriction: Eligible for patients 6 years of age and older.

Special Population Status

  • Renal/Hepatic Impairment: Patients with renal impairment or mild-to-moderate hepatic impairment are generally eligible, as dose adjustment is not required.
  • Pregnancy and Lactation: Use during pregnancy and breastfeeding is generally permitted when the clinical benefit to the mother is considered clearly essential, as Montelukast is present in human milk in very small amounts.

What should I know about interactions with other medicines?

Interactions with other medicines and products

Official regulatory documents detail specific interactions for Montelukast (marketed as Monteka) based primarily on its metabolism by cytochrome P450 enzymes (CYP2C8, CYP2C9, and CYP3A4). These interactions may result in an altered concentration of Montelukast or the co-administered drug, requiring clinical attention and monitoring.

Interacting Product Category Specific Examples Listed Practical Constraint or Requirement
Enzyme Inducers Carbamazepine, Rifampin, Phenobarbital Co-administration may decrease Montelukast plasma concentrations, which could lead to reduced efficacy. Monitoring for loss of therapeutic effect is advised by regulatory documents.
CYP2C8 Inhibitors Gemfibrozil Co-administration may significantly increase the systemic exposure of Montelukast, requiring monitoring for increased effects.
Oral Anticoagulants Warfarin Montelukast does not appear to have clinically important effects on the pharmacokinetics of Warfarin, but close monitoring of coagulation parameters (Prothrombin Time/INR) is still advised when the two are used together.
Other Medications Prednisone, Theophylline, Digoxin Official studies show that Montelukast has no clinically significant effect on the pharmacokinetics of these specific drugs and no interaction-related constraints are specified for their co-administration.

Procedural Constraints: The chewable tablet formulation contains phenylalanine and is contraindicated in patients with phenylketonuria (PKU). This constraint is based on a component-specific interaction with this patient population.

Mechanism of Action

Monteka acts as a Leukotriene Receptor Antagonist, modulating inflammatory pathways at the cellular level. The mechanism is highly specific and results in a physiological effect that reduces CysLT-mediated signaling.

Selective Blockade of the CysLT1 Receptor

The drug acts by binding with high affinity to the Cysteinyl Leukotriene Type 1 receptor ( CysLT1), found on airway smooth muscle and inflammatory cells. This interaction creates a competitive blockade that prevents the body's natural inflammatory signals—the cysteinyl leukotrienes ( LTD4, LTC4, LTE4)—from initiating their biological effects. As a result, the drug interrupts the leukotriene signaling cascade without activating the receptor itself.

Physiological Consequences of Receptor Blockade

By neutralizing the CysLT1 receptor, the mechanism produces three primary physiological consequences in the respiratory system. First, it prevents smooth muscle contraction and LTD4-induced bronchospasm. Second, it reduces vascular permeability, which limits CysLT-mediated airway edema (swelling) and mucus secretion. Third, it interferes with the signals that promote the recruitment and infiltration of inflammatory cells like eosinophils into the airways. This action provides a sustained blockade of the leukotriene signaling pathway.

Dosage and Administration Information

Administration and Dosing Principles

Monteka (Montelukast sodium) is administered exclusively via the oral route across all its approved formulations: film-coated tablets, chewable tablets, and oral granules. The approach to using the medication is standardized, requiring once-daily administration for chronic management.


Standard Daily Dosing Regimens

The numerical dose is strictly dependent on age and the therapeutic purpose. The fixed dosage strengths are not subject to titration and are summarized below:

Population Official Dose (Once Daily)
Adults & Adolescents (ge 15 years) 10 mg
Children (6–14 years) 5 mg (Chewable Tablet)
Children (2–5 years) 4 mg (Chewable Tablet or Granules)

Frequency and Context of Use

The standard frequency for all indications is once daily. For the chronic treatment of asthma, the daily dose is consistently administered in the evening. When used for isolated allergic rhinitis, the timing is more flexible, allowing administration in the morning or evening. The medicine may be taken with or without food.

Specific procedural rules apply to the oral granules: they must be administered either directly or mixed with breast milk, formula, or specific soft foods (such as applesauce or rice). The full dose must be consumed within 15 minutes of opening the packet; the preparation cannot be stored.

No dosage adjustment is required for older adult patients, nor for those with mild-to-moderate renal or hepatic impairment. Furthermore, only one dose of Monteka is permitted per 24-hour period, regardless of the number of indications being treated.
