Generic Singulair Information

Introduction

Singulair (generic name Montelukast) is a leukotriene‑receptor antagonist indicated primarily for the long‑term management of asthma and for the relief of allergic rhinitis. In the United Kingdom it is prescribed by respiratory physicians, general practitioners and allergy specialists as part of an evidence‑based treatment plan. The active compound, Montelukast, blocks the inflammatory actions of leukotrienes – chemical mediators released in response to allergens or irritants. While the product originated from Merck Sharp & Dohme, many reputable manufacturers now supply the same molecule in generic form, offering a cost‑effective alternative for patients who need regular therapy.

What is Singulair?

Singulair is a tablet formulation that contains the single active ingredient Montelukast sodium. It belongs to the drug class known as leukotriene‑receptor antagonists (LTRAs) and is marketed for asthma control and allergic rhinitis symptoms. The original brand was developed by Merck & Co. and received a UK marketing authorisation in 1998. Since then, several licensed generic versions – for example Montair, Montelukast Sandoz, and Montelukast Teva – have been approved by the Medicines and Healthcare products Regulatory Agency (MHRA).

Our online pharmacy provides this generic alternative as a cost‑effective treatment option, delivering the identical active compound in a tablet that meets the same quality standards required for UK medications.

How Singulair Works

Montelukast selectively binds to cysteinyl‑leukotriene type 1 (CysLT₁) receptors located on airway smooth muscle, sub‑mucosal glands and inflammatory cells. By occupying these receptors, it prevents leukotriene D₄, E₄ and F₄ – the most potent bronchoconstrictors and mucus‑secreting agents – from exerting their effect.

The result is a reduction in airway inflammation, decreased bronchial hyper‑responsiveness, and relief of nasal congestion and sneezing. Pharmacokinetic data from the European Medicines Agency (EMA) show that Montelukast reaches peak plasma concentrations within 3–4 hours after oral intake, has a terminal half‑life of approximately 4–6 days, and is eliminated mainly via hepatic metabolism (CYP3A4, CYP2C9). These properties give the drug a once‑daily dosing schedule and a steady therapeutic effect that persists even when occasional doses are missed.

Conditions Treated with Singulair

• Persistent asthma (adult and adolescent) – Used as an add‑on therapy for patients whose disease is not fully controlled by inhaled corticosteroids (ICS) alone. Clinical trials in the UK have demonstrated a 20–30 % reduction in exacerbation rates when Montelukast is combined with standard inhaler therapy.

• Exercise‑induced bronchoconstriction (EIB) – A single dose taken 2 hours before physical activity can prevent the typical fall in forced expiratory volume (FEV₁) that occurs in up to 70 % of asthmatics.

• Seasonal allergic rhinitis (hay fever) – Montelukast reduces nasal itching, sneezing and rhinorrhoea by limiting leukotriene‑mediated inflammation of the nasal mucosa.

• Perennial allergic rhinitis – In patients exposed to indoor allergens (dust‑mite, pet dander) the medication provides consistent symptom control throughout the year.

• Aspirin‑exacerbated respiratory disease (AERD) – Montelukast is recommended as part of a multimodal regimen for adults who experience bronchospasm after non‑steroidal anti‑inflammatory drug (NSAID) exposure.

The prevalence of asthma in the UK is estimated at 5–7 % of the adult population, while allergic rhinitis affects roughly 15 % of adults, making Montelukast a widely relevant therapeutic option.

Who is Singulair For?

• Adults with mild‑to‑moderate persistent asthma who remain symptomatic despite low‑medium dose inhaled corticosteroids.
• Patients who experience exercise‑induced bronchoconstriction and need a preventive, non‑inhaled option.
• Individuals with seasonal or perennial allergic rhinitis whose symptoms are not fully controlled by antihistamines alone.
• Adults diagnosed with aspirin‑exacerbated respiratory disease requiring additional leukotriene blockade.

Contra‑indications and cautionary scenarios include:

• Pregnancy and lactation – Montelukast is classified as Pregnancy Category B (UK) but should only be used when the expected benefit justifies the potential risk.
• Severe hepatic impairment – Reduced metabolism may increase plasma concentrations; dose adjustment is advised.
• Known hypersensitivity to Montelukast or any excipient – An allergic reaction mandates immediate discontinuation.

Patients with uncontrolled psychiatric illness, particularly recent depressive episodes or suicidal thoughts, should discuss risks with a healthcare professional before initiating therapy, as post‑marketing surveillance has identified rare neuropsychiatric events.

Risks, Side Effects, and Interactions

Common

• Headache
• Upper respiratory tract infection (viral‑type symptoms)
• Stomach pain or dyspepsia
• Nasopharyngitis

These events are typically mild, transient, and occur in ≤10 % of users in clinical studies.

Rare

• Mood changes (irritability, anxiety)
• Sleep disturbances (insomnia, vivid dreams)
• Elevated liver enzymes (ALT/AST)

Reported in <1 % of patients; routine monitoring is not required unless clinical suspicion arises.

Serious

• Neuropsychiatric reactions – Including depression, suicidal ideation, and behavioural changes. Although causal relationship remains under investigation, the MHRA advises prompt medical evaluation if such symptoms develop.
• Severe allergic reactions – Anaphylaxis, angio‑oedema, or urticaria. Discontinue immediately and seek emergency care.
• Hepatic failure – Extremely rare; indicated by jaundice, dark urine, or persistent abdominal pain.

Clinically Relevant Drug‑Drug Interactions

• Ritonavir and other potent CYP3A4 inhibitors – May increase Montelukast plasma levels; monitor for enhanced side‑effects.
• Phenobarbital, carbamazepine, rifampicin (CYP inducers) – May reduce drug exposure, potentially diminishing efficacy.
• Warfarin – No direct interaction, but routine INR monitoring is advised as any change in hepatic function could affect metabolism.

Patients should always disclose over‑the‑counter products, herbal supplements (e.g., St John’s wort) and any chronic medication to their prescriber.

Practical Use: Dosing, Missed Dose, Overdose

• Standard adult dosing – 10 mg Montelukast tablet taken orally once daily in the evening with or without food. For asthma patients with episodic symptoms, the same dose may be taken in the morning; consistency is the key to maintaining therapeutic plasma concentrations.

• Pediatric dosing – Not covered in this article; the UK formulary recommends 4 mg for children 6–14 kg and 5 mg for those 15–30 kg, administered in the evening.

• Missed dose – If a dose is forgotten, take it as soon as remembered unless it is close to the next scheduled dose. In that case, skip the missed tablet and resume the regular dosing time; do not double‑dose.

• Overdose – Single‑tablet overdose (≥20 mg) has been documented without serious toxicity. Nevertheless, if an accidental overdose is suspected, seek immediate medical assessment. Supportive care and observation are the mainstays of management.

• Food and alcohol – Montelukast absorption is not significantly affected by meals; it may be taken with or without food. Moderate alcohol consumption does not alter its efficacy, but excess alcohol can exacerbate gastrointestinal side‑effects.

• Comorbidities – In patients with chronic kidney disease, no dose adjustment is necessary. In hepatic impairment, the recommended dose remains 10 mg, but clinicians may consider a lower dose (5 mg) in severe cases.

FAQ

• Is Montelukast available in both brand‑name and generic forms in the UK?
  Yes. The original brand‑name product is Singulair, marketed by Merck. Generic Montelukast tablets—such as Montair, Montelukast Sandoz and Montelukast Teva—contain the same active ingredient and are approved by the MHRA.

• Can Montelukast be stored in a refrigerator?
  No refrigeration is required. The tablets should be kept at controlled room temperature (15–30 °C), protected from moisture, light and excessive heat.

• What does the tablet look like?
  Generic 10 mg Montelukast tablets are typically round or oval, white to off‑white, and may be scored for easy splitting. The imprint varies by manufacturer (e.g., “M10”, “10 S”).

• Are there differences in inactive ingredients between UK and overseas formulations?
  In the UK, excipients commonly include lactose, microcrystalline cellulose, and magnesium stearate. Some Asian formulations may contain alternative fillers such as corn starch. Patients with specific allergies should verify the full ingredient list provided on the packaging.

• How does personal import of Montelukast work under UK law?
  The UK government permits individuals to import a three‑month supply of a prescription‑only medicine for personal use, provided it is for a legitimate medical need and the source is an authorised pharmacy. Our online pharmacy ensures compliance with these regulations.

• Will Montelukast appear on drug‑testing panels for employment or sports?
  Montelukast is not a prohibited substance in standard occupational or anti‑doping screening panels. It is considered a therapeutic drug and does not affect performance‑enhancing test results.

• Can I travel with Montelukast tablets across EU borders?
  Yes, provided you carry a copy of the prescription or a professional medical statement confirming its necessity. Keeping the medication in its original labelled packaging helps avoid customs complications.

• What is the history behind the development of leukotriene‑receptor antagonists?
  The concept emerged in the 198s when researchers identified leukotrienes as key mediators of bronchoconstriction. Montelukast, the first approved LTRA, received regulatory approval in the United States in 1998 and shortly thereafter in Europe, revolutionising non‑steroidal asthma management.

• How does Montelukast compare with inhaled corticosteroids for asthma control?
  Inhaled corticosteroids remain the cornerstone of anti‑inflammatory therapy. Montelukast is an adjunct, offering additional control for patients who continue to experience symptoms despite optimal inhaler use, or for those who prefer an oral option to reduce inhaler technique errors.

• Is there any evidence that Montelukast reduces the need for rescue inhalers?
  Controlled trials have shown a modest reduction (approximately 10–15 %) in short‑acting beta‑agonist (SABA) use among adults adding Montelukast to their regimen, reflecting improved baseline airway stability.

• Do climatic conditions affect Montelukast’s stability?
  Extreme temperatures above 30 °C or high humidity can accelerate degradation of the tablet’s active ingredient. Storing the medication in a cool, dry place prolongs its shelf life up to the printed expiry date.

• Can Montelukast be taken with other asthma medications such as LABA or LAMA?
  Yes. Montelukast is frequently prescribed alongside long‑acting beta‑agonists (LABA) and long‑acting muscarinic antagonists (LAMA) as part of a step‑wise asthma management plan. No pharmacokinetic interactions have been identified.
