4.1 Therapeutic indication

For the treatment of symptoms of allergic rhinitis with nasal congestion.

4.2 Posology and method of administration

The recommended dose is two spray actuations (27.5 micrograms of. Fluticasone Furoate and 50 mcg of Oxymetazoline Hydrochloride per spray actuation) in each nostril once daily (total daily dose, 110 micrograms of Fluticasone Furoate and 200 mcg of Oxymetazoline Hydrochloride). Once adequate control of symptoms is achieved, dose reduction to one spray actuation in each nostril (total daily dose 55 micrograms of Fluticasone Furoate and 100 mcg of Oxymetazoline Hydrochloride) may be effective for maintenance.

Fluticasone Furoate and Oxymetazoline Hydrochloride Nasal Spray is for administration by the intranasal route only.

The intranasal device should be shaken before use. The device is primed by pressing the mist release button for at least six spray actuations (until a fine mist is seen), whilst holding the device upright. Re-priming (approximately 6 sprays until a fine mist is seen) is only necessary if the cap is left off for 5 days or the intranasal device has not been used for 30 days or more.

4.4 Special warnings and precautions for use

Keep the spray away from the eyes.

Systemic corticosteroid effects

Systemic effects of nasal corticosteroid may occur, particularly at high doses prescribed for prolonged periods. These effects are much less likely tooccur than with oral corticosteroids and may vary in individual patients and between different corticosteroid preparations. Potential systemic effects may include Cushing's syndrome, Cushingoid features, adrenal suppression, growth retardation in children and adolescents, cataract, glaucoma and more rarely, a range of psychological or behavioural effects including psychomotor hyperactivity, sleep disorders, anxiety, depression or aggression (particularly in children). Treatment with higher than recommended doses of nasal corticosteroids may result in clinically significant adrenal suppression. If there is evidence for higher than recommended doses being used, then additional systemic corticosteroid cover should be considered during periods of stress or elective surgery. Fluticasone furoate 110 micrograms once daily has not been associated with hypothalamic-pituitary-adrenal (HPA) axis suppression in adult or adolescent subjects. However, the dose of intranasal fluticasone furoate should be reduced to the lowest dose at which effective control of the symptoms of rhinitis is maintained. As with all intranasal corticosteroids, the total systemic burden of corticosteroids should be considered whenever other forms of corticosteroid treatment are prescribed concurrently. If there is any reason to believe that adrenal function is impaired, care must be taken when transferring patients from systemic steroid treatment to fluticasone furoate.

Visual disturbance

Visual disturbance may be reported with systemic and topical corticosteroid use. If a patient present with symptoms such as blurred vision or other visual disturbances, the patient should be considered for referral to an ophthalmologist for evaluation of possible causes which may include cataract, glaucoma or rare diseases such as central serous chorioretinopathy (CSCR) which have been reported after use of systemic and topical corticosteroids.

Growth retardation

Growth retardation has been reported in children receiving nasal corticosteroids at licensed doses. A reduction in growth velocity has been observed in children treated with fluticasone furoate 110 micrograms daily for one year. Therefore, children should be maintained on the lowest possible efficacious dose which delivers adequate symptom control. It is recommended that the growth of children receiving prolonged treatment with nasal corticosteroids is regularly monitored. If growth is slowed, therapy should be reviewed with the aim of reducing the dose of nasal corticosteroid if possible, to the lowest dose at which effective control of symptoms is maintained.

Patients on ritonavir

Concomitant administration with ritonavir is not recommended because of the risk of increased systemic exposure of fluticasone Furoate.

4.5 Drug interactions

Interaction with CYP3A inhibitors

Fluticasone furoate is rapidly cleared by extensive first-pass metabolism mediated by the cytochrome P450 3A4.

Based on data with another glucocorticoid (fluticasone propionate), that is metabolised by CYP3A4, coadministration with ritonavir is not recommended because of the risk of increased systemic exposure of fluticasone furoate. Caution is recommended when co-administering fluticasone furoate with potent CYP3A inhibitors including cobicistat containing products as an increase in the risk of systemic side effects is expected. Co-administration should be avoided unless the benefit outweighs the increased risk of systemic corticosteroid side effects, in which case patients should be monitored for systemic corticosteroid side effects. In a drug interaction study of intranasal fluticasone furoate with the potent CYP3A4 inhibitor ketoconazole there were more subjects with measurable fluticasone furoate concentrations in the ketoconazole group (6 of the 20 subjects) compared to placebo (1 out of 20 subjects). This small increase in exposure did not result in a statistically significant difference in 24-hour serum cortisol levels between the two groups.

The enzyme induction and inhibition data suggest that there is no theoretical basis for anticipating metabolic interactions between fluticasone furoate and the cytochrome P450 mediated metabolism of other compounds at clinically relevant intranasal doses. Therefore, no clinical studies have been conducted to investigate interactions of fluticasone furoate on other drugs Monoamine oxidase inhibitors (MAOIs), nonselective beta adrenergic antagonists, or tricyclic antidepressants.

Use of Oxymetazoline containing nasal spray in combination with monoamine oxidase inhibitors (MAOIs), nonselective beta adrenergic antagonists, or tricyclic antidepressants may cause hypertension and is not recommended.

4.6 Use in special populations

Pregnancy

There are no adequate data from the use of fluticasone furoate and Oxymetazoline containing nasal sprays in pregnant women. In animal studies glucocorticoids have been shown to induce malformations including cleft palate and intra-uterine growth retardation. This is not likely to be relevant for humans given recommended nasal doses which results in minimal systemic exposure.

Breast-feeding

It is unknown whether nasal administered fluticasone furoate or Oxymetazoline is excreted in human breast milk. Administration of Fluticasone Furoate and Oxymetazoline Hydrochloride Nasal Spray to women who are breast-feeding should only be considered if the expected benet to the mother is greater than any possible risk to the child.

Fertility

There are no fertility data in humans.

4.7 Effects on ability to drive and use machines

Fluticasone Furoate and Oxymetazoline Hydrochloride Nasal Spray has no or negligible influence on the ability to drive and use machines.

4.8 Undesirable effects

The most common AEs reported with the use of Fluticasone Furoate and Oxymetazoline containing Nasal Spray are epistaxis, nasal ulceration, nasal dryness & discomfort, sneezing and headache. The other AEs include : rhinalgia, transient ocular changes, vision blurred, nasal septum perforation, dry mouth, stomatitis, dry throat, local irritation, insomnia, sedation, anxiety, irritability, nausea, hypertension, irregular heart rate, increased heart rate, restlessness, somnolence, fatigue, hypersensitivity reactions including anaphylaxis, angioedema, rash, and urticaria. Prolonged use may cause rebound congestion and rhinitis medicamentosa.

4.9 Overdose

Overdosage may give rise to local irritation and rebound congestion. Treatment need only be symptomatic

5.1 Pharmacodynamic properties

Fluticasone furoate is a synthetic tri-fluorinated corticosteroid that possesses a very high affinity for the glucocorticoid receptor and has a potent anti-inflammatory action.

Oxymetazoline is a direct-acting sympathomimetic amine. It acts on alpha-adrenergic receptors in the vessels of the nasal mucosa producing vasoconstriction and decongestion.

5.2 Pharmacokinetic properties

Fluticasone Furoate

Absorption: Fluticasone furoate undergoes incomplete absorption and extensive first-pass metabolism in the liver and gut resulting in negligible systemic exposure. The intranasal dosing of 110 micrograms once daily does not typically result in measurable plasma concentrations (<10 pgl ml). The absolute bioavailability for intranasal uticasone furoate is 0.50 %, such that less than 1 microgram of fluticasone furoate would be systemically available after administration of 110 micrograms

Distribution: The plasma protein binding of fluticasone furoate is greater than 99%. Fluticasone furoate is widely distributed with volume of distribution at steady-state of, on average, 608 L.

Biotransformation: Fluticasone furoate is rapidly cleared (total plasma clearance of 58.7 I/h) from systemic circulation principally by hepatic metabolism to an inactive 17p-carboxylic metabolite (GW694301X), by the cytOchrome P450 enzyme CYP3A4. The principal route of metabolism was hydrolysis of the S-fluoromethyl carbothioate function to form the 1713- carboxylic acid metabolite. In vivo studies have revealed no evidence of cleavage of the furoate moiety to form fluticasone.

Elimination: Elimination is primarily via the faecal route following oral and intravenous administration indicative of excretion of fluticasone furoate and its metabolites via the bile. Following intravenous administration, the elimination phase half-life averaged 15.1 hours. Urinary excretion accounted for approximately 1 % and 2 % of the orally and intravenously administered dose, respectively.

Oxymetazoline Hydrochloride

Oxymetazoline enters tissues rapidly and local vasoconstriction is normally achieved within 5-10 minutes of intranasal administration. The full effect lasts for 5-6 hours and then gradually subsides over the next 6 hours. Plasma half-life is 5-8 days with 30% of any absorbed drug being excreted in the urine unchanged and 10% being excreted in the faeces

6.1 Animal Toxicology or pharmacology

Fluticasone Furoate

Findings in general toxicology studies were similar to those observed with other glucocorticoids and are associated with exaggerated pharmacological activity. These findings are not likely to be relevant for humans given recommended nasal doses which results in minimal systemic exposure. No genotoxic effects of fluticasone furoate have been observed in conventional genotoxicity tests. Further, there were no treatment-related increases in the incidence of tumours in two-year inhalation studies in rats and mice.
