Glemont 10 mg film-coated tablets is indicated in the treatment of asthma as add-on therapy in adults and adolescents from 15 years of age and older with mild to moderate persistent asthma who are inadequately controlled on inhaled corticosteroids and in whom “as-needed†short acting beta-agonists provide inadequate clinical control of asthma. In those asthmatic patients in whom Glemont 10 mg film-coated tablets is indicated in asthma, Glemont 10 mg film-coated tablets can also provide symptomatic relief of seasonal allergic rhinitis.
Glemont 10 mg film-coated tablets is also indicated in the prophylaxis of asthma in which the predominant component is exercise-induced bronchoconstriction.
Posology:
The dosage for adults and adolescents 15 years of age and older with asthma, or with asthma and concomitant seasonal allergic rhinitis, is one 10 mg tablet daily to be taken in the evening.
General recommendations:
The therapeutic effect of Glemont 10 mg film-coated tablets on parameters of asthma control occurs within one day. Glemont 10 mg film-coated tablets may be taken with or without food. Patients should be advised to continue taking Glemont 10 mg film-coated tablets even if their asthma is under control, as well as during periods of worsening asthma. Glemont 10 mg film-coated tablets should not be used concomitantly with other products containing the same active ingredient, Glemont.
No dosage adjustment is necessary for the elderly, or for patients with renal insufficiency, or mild to moderate hepatic impairment. There are no data on patients with severe hepatic impairment. The dosage is the same for both male and female patients.
Therapy with Glemont 10 mg film-coated tablets in relation to other treatments for asthma
Glemont 10 mg film-coated tablets can be added to a patient's existing treatment regimen.
Inhaled corticosteroids:
Treatment with Glemont 10 mg film-coated tablets can be used as add-on therapy in patients when inhaled corticosteroids plus "as needed" short acting beta-agonists provide inadequate clinical control. Glemont 10 mg film-coated tablets should not be abruptly substituted for inhaled corticosteroids.
Paediatric population
Do not give Glemont 10 mg film-coated tablets to children less than 15 years of age. The safety and efficacy of Glemont 10 mg film-coated tablets in children less than 15 years has not been established.
10 mg film-coated tablets are available for adults and adolescents above 15 years old.
Other available strengths/pharmaceutical forms:
5 mg chewable tablets are available for paediatric and adolescents patients 6 to 14 years of age.
4 mg chewable tablets are available for paediatric patients 2 to 5 years of age.
Method of administration:
Oral use.
Patients should be advised never to use oral Glemont to treat acute asthma attacks and to keep their usual appropriate rescue medication for this purpose readily available. If an acute attack occurs, a short-acting inhaled beta-agonist should be used. Patients should seek their doctor's advice as soon as possible if they need more inhalations of short-acting beta-agonists than usual.
Glemont should not be substituted abruptly for inhaled or oral corticosteroids.
There are no data demonstrating that oral corticosteroids can be reduced when Glemont is given concomitantly.
In rare cases, patients on therapy with anti-asthma agents including Glemont may present with systemic eosinophilia, sometimes presenting with clinical features of vasculitis consistent with Churg-Strauss syndrome, a condition which is often treated with systemic corticosteroid therapy. These cases have been sometimes associated with the reduction or withdrawal of oral corticosteroid therapy. Although a causal relationship with leukotriene receptor antagonism has not been established, physicians should be alert to eosinophilia, vasculitic rash, worsening pulmonary symptoms, cardiac complications, and/or neuropathy presenting in their patients. Patients who develop these symptoms should be reassessed and their treatment regimens evaluated.
Treatment with Glemont does not alter the need for patients with aspirin-sensitive asthma to avoid taking aspirin and other non-steroidal anti-inflammatory drugs.

Glemont has been evaluated in clinical studies as follows:
- 10 mg film-coated tablets in approximately 4000 adult and adolescent asthmatic patients 15 years of age and older.
- 10 mg film-coated tablets in approximately 400 adult and adolescent asthmatic patients with seasonal allergic rhinitis 15 years of age and older.
- 5 mg chewable tablets in approximately 1750 paediatric asthmatic patients 6 to 14 years of age.
The following drug-related adverse reactions in clinical studies were reported commonly (1/100 to <1/10) in asthmatic patients treated with Glemont and at a greater incidence than in patients treated with placebo:
| Body system Class | Adult Patients 15 years and older (two 12-week studies; n=795) | Paediatric and adolescents Patients 6 to 14 years old (one 8-week study; n=201) (two 56-week studies; n=615) |

Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme Website: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.
In chronic asthma studies, Glemont has been administered at doses up to 200 mg/day to patients for 22 weeks and in short term studies, up to 900 mg/day to patients for approximately one week without clinically important adverse experiences.
There have been reports of acute overdose in post-marketing experience and clinical studies with Glemont. These include reports in adults and children with a dose as high as 1000 mg (approximately 61 mg/kg in a 42 month old child). The clinical and laboratory findings observed were consistent with the safety profile in adults and paediatric patients.
Symptoms of overdose
There were no adverse experiences in the majority of overdose reports. The most frequently occurring adverse experiences were consistent with the safety profile of Glemont and included abdominal pain, somnolence, thirst, headache, vomiting and psychomotor hyperactivity.
Management of overdose
No specific information is available on the treatment of overdose with Glemont. It is not known whether Glemont is dialysable by peritoneal- or haemo-dialysis.
Pharmacotherapeutic group: Other systemic drugs for obstructive airway diseases, Leukotriene receptor antagonist
ATC code: R03D C03
The cysteinyl leukotrienes (LTC4, LTD4, LTE4) are potent inflammatory eicosanoids released from various cells including mast cells and eosinophils. These important pro-asthmatic mediators bind to cysteinyl leukotriene (CysLT) receptors. The CysLT type-1 (CysLT1) receptor is found in the human airway (including airway smooth muscle cells and airway macrophages) and on other pro-inflammatory cells (including eosinophils and certain myeloid stem cells). CysLTs 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, CysLTs 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 CysLTs has been shown to increase nasal airway resistance and symptoms of nasal obstruction.
Glemont is an orally active compound which binds with high affinity and selectivity to the CysLT1 receptor. In clinical studies, Glemont inhibits bronchoconstriction due to inhaled LTD4 at doses as low as 5 mg. Bronchodilation was observed within 2 hours of oral administration. The bronchodilation effect caused by a beta agonist was additive to that caused by Glemont. Treatment with Glemont inhibited both early- and late phase bronchoconstriction due to antigen challenge. Glemont, compared with placebo, decreased peripheral blood eosinophils in adult and paediatric patients. In a separate study, treatment with Glemont significantly decreased eosinophils in the airways (as measured in sputum) and in peripheral blood while improving clinical asthma control.
In studies in adults, Glemont, 10 mg once daily, compared with placebo, demonstrated significant improvements in morning FEV1 (10.4% vs 2.7% change from baseline), AM peak expiratory flow rate (PEFR) (24.5 L/min vs 3.3 L/min change from baseline), and significant decrease in total beta-agonist use ( -26.1% vs -4.6% change from baseline). Improvement in patient-reported daytime and nighttime asthma symptoms scores was significantly better than placebo.
Studies in adults demonstrated the ability of Glemont to add to the clinical effect of inhaled corticosteroid (% change from baseline for inhaled beclometasone plus Glemont vs beclometasone, respectively for FEV1: 5.43% vs 1.04%; beta-agonist use: -8.70% vs 2.64%). Compared with inhaled beclometasone (200 µg twice daily with a spacer device), Glemont demonstrated a more rapid initial response, although over the 12-week study, beclometasone provided a greater average treatment effect (% change from baseline for Glemont vs beclometasone, respectively for FEV1: 7.49% vs 13.3%; beta agonist use: -28.28% vs -43.89%). However, compared with beclometasone, a high percentage of patients treated with Glemont achieved similar clinical responses (e.g., 50% of patients treated with beclometasone achieved an improvement in FEV1 of approximately 11% or more over baseline while approximately 42% of patients treated with Glemont achieved the same response).
A clinical study was conducted to evaluate Glemont for the symptomatic treatment of seasonal allergic rhinitis in adult asthmatic patients 15 years of age and older with concomitant seasonal allergic rhinitis. In this study, Glemont 10 mg tablets administered once daily demonstrated a statistically significant improvement in the Daily Rhinitis Symptoms score, compared with placebo. The Daily Rhinitis Symptoms score is the average of the Daytime Nasal Symptoms score (mean of nasal congestion, rhinorrhea, sneezing, nasal itching) and the Nighttime Symptoms score (mean of nasal congestion upon awakening, difficulty going to sleep, and nighttime awakenings scores). Global evaluations of allergic rhinitis by patients and physicians were significantly improved, compared with placebo. The evaluation of asthma efficacy was not a primary objective in this study.
In an 8-week study in paediatric patients 6 to 14 years of age, Glemont 5 mg once daily, compared with placebo, significantly improved respiratory function (FEV1 8.71% vs 4.16% change from baseline; AM PEFR 27.9 L/min vs 17.8 L/min change from baseline) and decreased "as-needed" beta-agonist use (-11.7% vs +8.2% change from baseline).
Significant reduction of exercise-induced bronchoconstriction (EIB) was demonstrated in a 12-week study in adults (maximal fall in FEV1 22.33% for Glemont vs 32.40% for placebo; time to recovery to within 5% of baseline FEV1 44.22 min vs 60.64 min). This effect was consistent throughout the 12-week study period. Reduction in EIB was also demonstrated in a short term study in paediatric patients (maximal fall in FEV1 18.27% vs 26.11%; time to recovery to within 5% of baseline FEV1 17.76 min vs 27.98 min). The effect in both studies was demonstrated at the end of the once-daily dosing interval.
In aspirin-sensitive asthmatic patients receiving concomitant inhaled and/or oral corticosteroids, treatment with Glemont, compared with placebo, resulted in significant improvement in asthma control (FEV1 8.55% vs -1.74% change from baseline and decrease in total beta-agonist use -27.78% vs 2.09% change from baseline).
Absorption
Glemont is rapidly absorbed following oral administration. For the 10 mg film-coated tablet, the mean peak plasma concentration (Cmax) is achieved 3 hours (Tmax) after administration 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.
For the 5 mg chewable tablet, the Cmax is achieved in 2 hours after administration in adults in the fasted state. The mean oral bioavailability is 73% and is decreased to 63% by a standard meal.
Distribution
Glemont is more than 99% bound to plasma proteins. The steady-state volume of distribution of Glemont averages 8-11 litres. Studies in rats with radiolabelled Glemont indicate minimal distribution across the blood-brain barrier. In addition, concentrations of radiolabelled material at 24 hours post-dose were minimal in all other tissues.
Biotransformation
Glemont is extensively metabolised. In studies with therapeutic doses, plasma concentrations of metabolites of Glemont are undetectable at steady state in adults and children.
Cytochrome P450 2C8 is the major enzyme in the metabolism of Glemont. Additionally CYP 3A4 and 2C9 may have a minor contribution, although itraconazole, an inhibitor of CYP 3A4, was shown not to change pharmacokinetic variables of Glemont in healthy subjects that received 10 mg Glemont daily. Based on in vitro results in human liver microsomes, therapeutic plasma concentrations of Glemont do not inhibit cytochromes P450 3A4, 2C9, 1A2, 2A6, 2C19, or 2D6. The contribution of metabolites to the therapeutic effect of Glemont is minimal.
Elimination
The plasma clearance of Glemont averages 45 ml/min in healthy adults. Following an oral dose of radiolabelled Glemont, 86% of the radioactivity was recovered in 5-day faecal collections and <0.2% was recovered in urine. Coupled with estimates of Glemont oral bioavailability, this indicates that Glemont and its metabolites are excreted almost exclusively via the bile.
Characteristics in patients
No dosage adjustment is necessary for the elderly or mild to moderate hepatic insufficiency. Studies in patients with renal impairment have not been undertaken. Because Glemont and its metabolites are eliminated by the biliary route, no dose adjustment is anticipated to be necessary in patients with renal impairment. There are no data on the pharmacokinetics of Glemont in patients with severe hepatic insufficiency (Child-Pugh score>9).
With high doses of Glemont (20- and 60-fold the recommended adult dose), decrease in plasma theophylline concentration was observed. This effect was not seen at the recommended dose of 10 mg once daily.
In animal toxicity studies, minor serum biochemical alterations in ALT, glucose, phosphorus and triglycerides were observed which were transient in nature. The signs of toxicity in animals were increased excretion of saliva, gastro-intestinal symptoms, loose stools and ion imbalance. These occurred at dosages which provided>17-fold the systemic exposure seen at the clinical dosage. In monkeys, the adverse effects appeared at doses from 150 mg/kg/day (>232-fold the systemic exposure seen at the clinical dose). In animal studies, Glemont did not affect fertility or reproductive performance at systemic exposure exceeding the clinical systemic exposure by greater than 24-fold. A slight decrease in pup body weight was noted in the female fertility study in rats at 200 mg/kg/day (>69fold the clinical systemic exposure). In studies in rabbits, a higher incidence of incomplete ossification, compared with concurrent control animals, was seen at systemic exposure>24-fold the clinical systemic exposure seen at the clinical dose. No abnormalities were seen in rats. Glemont has been shown to cross the placental barrier and is excreted in breast milk of animals.
No deaths occurred following a single oral administration of Glemont sodium at doses up to 5000 mg/kg in mice and rats (15,000 mg/m2 and 30,000 mg/m2 in mice and rats, respectively), the maximum dose tested. This dose is equivalent to 25,000 times the recommended daily adult human dose (based on an adult patient weight of 50 kg).
Glemont was determined not to be phototoxic in mice for UVA, UVB or visible light spectra at doses up to 500 mg/kg/day (approximately>200-fold based on systemic exposure).
Glemont was neither mutagenic in in vitro and in vivo tests nor tumorigenic in rodent species.
