In controlled clinical trials, the total incidence of adverse reactions associated with the use of fluticasone propionate cream, 0.05% was approximately 4%. These adverse reactions were mild and self-limiting. For fluticasone propionate cream 0.05%, these reactions consisted primarily of pruritus, dryness, numbness of fingers, and burning. These events occurred in 2.9%, 1.2%, 1.0% and 0.6% of patients, respectively.

The following additional local adverse reactions have been reported infrequently with other topical corticosteroids, and they may occur more frequently with the use of occlusive dressings, especially with higher potency corticosteroids. These reactions are listed in an approximately decreasing order of occurrence: irritation, dryness, folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, skin atrophy, striae, dilation of the superficial blood vessels and miliaria. Also, there are reports of the development of pustular psoriasis from chronic plaque psoriasis following reduction or discontinuation of potent topical steroid products.

In a clinical study that compared once daily to twice daily dosing of CUTIVATE (fluticasone propionate) cream, the local adverse events that were considered to be drug related were as follows.

Cutivate should not be used under occlusive dressing.

Avoid prolonged application to the face since the face, more than other areas of the body, may exhibit atrophic changes after prolonged treatment with potent topical corticosteroids. This must be borne in mind when treating such conditions as psoriasis, discoid lupus erythematosus and severe eczema.

If applied to the eyelids, care is needed to ensure that the preparation does not enter the eye to avoid the risk of local irritation or glaucoma.

General

Systemic absorption of topical corticosteroids can produce reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for glucocorticos-teroid insufficiency after withdrawal from treatment. Manifestations of CushingÕs syndrome, hyperglycemia, and glucosuria can also be produced in some patients by systemic absorption while on therapy.

Patients receiving a large dose of a potent topical steroid applied to a large surface area or under occlusive dressing should be evaluated periodically for evidence of HPA axis suppression. This may be done by using the ACTH stimulation, morning plasma cortisol, and urinary free cortisol tests.

Fluticasone propionate cream, 0.05% produced HPA axis suppression within seven days when used at a dose of 30 g per day in diseased patients. In a study of the effects of fluticasone propionate cream, 0.05% on the HPA axis, a total of 30 g per day was used in two applications daily for seven days to six patients with psoriasis or atopic dermatitis involving at least 30% of the body surface. One patient developed evidence of adrenal suppression after six days of treatment with a below normal plasma cortisol level that returned to low normal levels the following day. Another patient developed a 60% decrease (although never below normal) in the plasma cortisol level from pre-treatment values after 2 days of treatment. This suppression persisted at this level for 48 hours before recovering by day six of treatment. The results of this study indicate that fluticasone propionate cream, 0.05% may be able to suppress the HPA axis within a few days with a dose of 30g per day.

If HPA axis suppression is noted, an attempt should be made to withdraw the drug, to reduce the frequency of application or to substitute a less potent steroid. Recovery of HPA axis function is generally prompt and complete upon discontinuation of topical glucocorticosteroids. Infrequently, signs and symptoms of glucocor-ticosteroid insufficiency may occur that require supplemental systemic corticos-teroids.For information on systemic supplementation, see prescribing information for those products.

Topical steroids may be hazardous in psoriasis for a number of reasons, including rebound relapses, development of tolerances, risk of generalized pustular psoriasis and development of local or systemic toxicity due to impaired barrier function of the skin. If used in psoriasis, careful patient supervision is important.

If irritation develops, fluticasone propionate cream, 0.05% should be discontinued and appropriate therapy instituted. Allergic contact dermatitis with corticosteroids is usually diagnosed by observing failure to heal rather than noting a clinical exacerbation as with most topical products not containing corticosteroids. Such an observation should be corroborated with appropriate diagnostic patch testing. If concomitant skin infections are present or develop, an appropriate antifungal or antibacterial agent should be used. If a favourable response does not occur promptly, use of fluticasone propionate cream, 0.05% should be discontinued until the infection has been adequately controlled.

Use in Children

Safety and effectiveness in children and infants have not been established. Because of a higher ratio of skin surface to body mass, children are at greater risk than adults of HPA axis suppression when they are treated with topical corticos-teroids. Therefore, they are also at greater risk of glucocorticosteroid insufficiency after withdrawal of treatment and of CushingÕs syndrome while on treatment. Adverse effects including striae have been reported with inappropriate use of topical corticosteroids in infants and children.Calculation of the appropriate dosage for children should allow for their greater surface area to body weight.

HPA axis suppression, CushingÕs syndrome, and intracranial hypertension have been reported in children receiving topical corticosteroids. Manifestations of adrenal suppression in children include linear growth retardation, delayed weight gain, low plasma cortisol levels, and absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headache, and bilateral papilledema.

Use in Pregnancy

Corticosteroids have been shown to be teratogenic in laboratory animals when administered systemically at relatively low dose levels. The more potent corticos-teroids have been shown to be teratogenic after dermal application in laboratory animals. There are no adequate and well-controlled studies in pregnant women. Fluticasone propionate ointment and cream should be used during pregnancy only if the potential benefit to the woman justifies the potential risk to the fetus.

Nursing Mothers

Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. It is not known whether topical administration of corticos-teroids could result in sufficient systemic absorption to produce detectable quantities in human milk. Because many drugs are excreted in human milk, caution should be exercised when fluticasone propionate cream, 0.05% is administered to a nursing woman.

Laboratory Tests

The following tests may be helpful in evaluating patients for HPA axis suppression: ACTH stimulation test; A.M. plasma cortisol test; urinary free cortisol test.

Symptoms and Treatment of Overdosage

Overdosage may cause the features of hypercorticism to appear. As with any corticosteroid, treatment should be discontinued if the symptoms of hypercorticism appear.Topically applied fluticasone propionate cream, 0.05% can be absorbed in sufficient amounts to produce systemic effects. (See PRECAUTIONS)

Fluticasone propionate cream, 0.05% is not indicated in patients with a hypersensitivity to any of the components. The preparation also contraindicated in the treatment of rosacea, acne vulgaris, perioral dermatitis, primary cutaneous viral infections (i.e., herpes simplex, chickenpox), perianal and genital pruritus, primarily infected skin lesions caused by infection with fungi or bacteria and dermatoses in children, including dermatitis and diaper rash.

Fluticasone propionate is a synthetic, fluorinated corticosteroid. Like other topical corticosteroids, fluticasone propionate has anti-inflammatory, anti-pruritic, and vasoconstrictive properties.The mechanism of the anti-inflammatory activity of the topical steroids, in general, is unclear. However, corticosteroids are thought to act by the induction of phospholipase A₂ inhibitory proteins, collectively called lipocortins. It is postulated that these proteins control the biosynthesis of potent mediators of inflammation such as prostaglandins and leukotrienes by inhibiting the release of their common precursor, arachidonic acid, which is released from membrane phospholipids by phospholipase A₂.

The extent of percutaneous absorption of topical corticosteroids is determined by many factors, including the vehicle and the integrity of the epidermal barrier. Occlusive dressing with hydrocortisone for up to 24 hours has not been demonstrated to increase penetration: however, occlusion of hydrocortisone for 96 hours markedly enhances penetration. Topical corticosteroids can be absorbed from normal intact skin, while inflammation and/or other disease processes in the skin increase percutaneous absorption.

Fluticasone propionate is lipophilic and has a strong affinity for the glucocorticoid receptor. It has weak affinity to the progesterone receptor, and virtually no affinity for the mineralocorticoid, estrogen, or androgen receptors.The therapeutic potency of glucocorticoids is related to the half-life of the glucocorticoid-receptor complex. Fluticasone propionate binding to the glucocorticoid receptor is rapid.

The half life of the fluticasone propionate-glucocorticoid receptor complex is approximately 10 hours.

Fluticasone propionate absorbed systemically is rapidly metabolized in the liver by esterase -catalyzed hydrolysis to the 17-beta-carboxylic acid which has no significant glucocorticoid or anti-inflammatory activity.

Pharmacology

Animals

Fluticasone propionate was shown to be approximately twice as potent in topical activity as beclomethasone according to the McKenzie vasoconstrictor assay.

Although relative vasoconstrictor activity does not necessarily imply similar relative therapeutic efficacy, evidence for local anti-inflammatory action without systemic effects has been demonstrated by studies in laboratory animals and confirmed in human clinical pharmacology studies.

Animal studies of the relative anti-inflammatory and hypothalamic-pituitary-adrenal (HPA) axis inhibitory potencies of topically applied drug demonstrated that fluticasone propionate has an advantageous therapeutic index ( > 200 times that of beclomethasone dipropionate).

Studies in rodents were conducted to quantitate and compare anti-inflammatory activity after topical administration of fluticasone propionate and the ability to produce specific systemic steroid-related effects after topical, oral or parenteral administration.

Topical anti-inflammatory activity was measured in rats and mice using the inflammatory response to croton oil applied topically to the ear. Results showed that fluticasone propionate was essentially equipotent with fluocinolone acetonide in both rats and mice.

Systemic responses to repeated topical applications of fluticasone propionate were assessed by measurement of thymus involution and reduction in stress-induced plasma corticosterone (HPA axis suppression) in rats and mice, and adrenal atrophy in the rat. In these tests, fluticasone propionate was 50-100-fold less potent than fluocinolone acetonide in the rat (56-fold greater therapeutic index) and 100 times less potent than fluocinolone acetonide in mice (relative therapeutic index 91). Therefore, in both species, the separation between topical anti-inflammatory and systemic activity after topical application, was highly favourable to fluticasone propionate.

Comparison of systemic activity after topical and subcutaneous dosing of flutica-sone propionate showed that, in both rats and particularly in mice, fluticasone propionate is more potent when given subcutaneously.

In rats, fluticasone propionate given subcutaneously was compared with betamethasone alcohol and fluocinolone acetonide using thymus involution, adrenal atrophy, and inhibition of carrageenin granuloma formulation as assessments of systemic activity. Fluticasone propionate was equipotent with betametha-sone alcohol and between 13 and 38 times less potent than fluocinolone acetonide.

In mice, using thymus involution and HPA axis suppression, fluticasone propionate given subcutaneously, was approximately equipotent with betamethasone alcohol and approximately 4 times less potent than fluocinolone acetonide.

After oral dosing in the rat, fluticasone propionate caused some thymus involution, adrenal atrophy and HPA axis suppression but was 6 to 38 times less potent than betamethasone alcohol. In the mouse, oral fluticasone propionate is 60 to 200 times less potent than betamethasone alcohol.

Fluticasone propionate was screened for a wide range of steroid hormonal or anti-hormonal activity.To ensure significant systemic exposure fluticasone propionate was administered subcutaneously to rats and mice, and was found to be devoid of androgenic, anabolic, oestrogenic, and anti-gonadotrophic activity. Fluticasone propionate had some progestational activity in oestrogen-primed weanling rabbits, and also showed some anti-androgenic and anti-oestrogenic activity. Weak anti-anabolic activity, another characteristic of potent glucocorticoids, was observed in the castrated rat. Fluticasone propionate lacked mineralocorticoid activity but caused significant diuresis and urinary excretion of sodium and potassium.

Pharmacokinetics

Pharmacokinetic data from rat, dog and man indicate that clearance is high relative to hepatic blood flow. Consequently, first-pass metabolism is extensive and oral bioavailability is negligible.

Studies examining the distribution of radio labelled fluticasone propionate in the rat have shown that orally-administered drug is absorbed and then excreted in the bile on first-pass through the liver. Thus, only minute traces of radioactivity pass into the systemic circulation.

The vast majority of a radio labelled dose following intravenous (rat and dog), oral and subcutaneous (mouse, rat and dog) administration is excreted via the faeces, and evidence from bile duct-cannulated animals indicates that the major route of excretion is via the bile. Renal excretion is of minor importance, as urinary excretion accounts for less than 5% of a parenteral dose. No unchanged drug is excreted in the bile of rats or dogs, but a significant amount, (up to 40%) of unchanged compound was found in the faeces of dogs dosed orally with flutica-sone propionate.

Thus, the low oral bioavailability of fluticasone propionate expected due to extensive first-pass metabolism is compounded by incomplete absorption from the gastrointestinal tract particularly in the dog. The major route of metabolism in rat, dog and humans is the hydrolysis of the fluorinated carbothioate group to yield the inactive carboxylic acid.

When administered orally to pregnant rats (100 µg/kg) or rabbits (300 µg/kg), a very small fraction of the dose ( < 0.005%) passes across the placenta.

Studies performed in rats following topical administration of radio labelled flutica-sone propionate cream or ointment have shown that only about 5% of the dose is absorbed through the skin, the majority of which is excreted in the faeces. The majority of the dose (73%) is recovered from the surface of the application site. Fluticasone propionate is stable and is not metabolized by dermal enzymes when incubated with human skin homogenates in vitro or when applied dermally to rats.

Human

In human volunteers, fluticasone propionate was 9.5 times more potent than fluoci-nolone acetonide and intermediate in potency between betamethasone-17-valerate (less potent) and clobetasol- 17-propionate (more potent).

No evidence of HPA axis suppression was seen in 45 healthy volunteers who repeatedly applied large amounts (between 30 g and 50 g per day) of fluticasone propionate ointment or cream formulations with or without occlusion. This was despite the fact that 15 of the 45 volunteers had applied 0.05% fluticasone propionate ointment (a ten-fold higher concentration of ointment than that currently marketed). The minimal effects on the HPA axis probably result from the relatively poor penetration of fluticasone propionate through the various layers of the skin.

Specialized studies have shown fluticasone propionate to have no potential to cause irritancy, contact sensitization, photo toxicity or photo contact allergenicity, despite the aggressive nature of the dosing schedules employed. Fluticasone propionate ointment (0.05%) and cream (0.005% and 0.05%) preparations were applied in volumes of 0.1 mL for up to 26 days in these specialised studies.

Pharmacokinetics

The pharmacokinetic characteristics following administration of fluticasone propionate in man are similar to those of other glucocorticoids, except that oral bioavailability is extremely low. This low oral bioavailability, coupled with high plasma clearance and efficient biliary excretion of metabolites, enhances the topical versus systemic effects. Studies with radio labelled and unlabelled flutica-sone propionate administered orally to human volunteers indicate that the majority of the dose (87%-100%) is excreted in the faeces, with up to 75% as unchanged drug, depending on the dose administered. Between 1% and 5% of the dose is excreted as metabolites in urine.

Single intravenous doses of 2 mg in healthy volunteers revealed that the clearance of fluticasone propionate approximates liver blood flow, with renal clearance accounting for less than 1%.These results indicate that hepatic extraction is almost complete and that oral bioavailability is close to zero. The plasma elimination half-life is approximately 3 hours, and the volume of distribution is approximately 260 L.

The poor penetration of fluticasone propionate, suggested from the minimal effects on the HPA axis, was also evidenced by low plasma concentrations after dermal application. The application of 12.5 g of 0.05% fluticasone propionate cream twice daily for 21 days without occlusion to healthy male volunteers resulted in trough plasma concentrations generally below the limit of detection (0.05 ng/mL) throughout the study.

Maximum trough levels of 0.069 to 0.39 ng fluticasone propionate/mL were observed following the twice daily application of 50 g of 0.05% fluticasone propionate cream under occlusion for 5 days.

The twice daily application of 25 g of 0.005% fluticasone propionate ointment under occlusion for 5 days to healthy male volunteers resulted in maximum trough levels in the range of 0.22 to 0.77 ng/mL.

Toxicology

Acute Toxicity

Pharmacokinetic studies in the rat have shown that only 5% of the dermal dose is absorbed through the skin.

However, intravenous and subcutaneous dosing allows toxicity to be fully charac-terised after maximal systemic exposure.

The results of the acute toxicity studies with fluticasone propionate administered by inhalation, orally, subcutaneously and intravenously, demonstrated a large margin of safety over the anticipated exposure of humans following the dermal application of cream preparations containing 0.05% fluticasone propionate. Systemic exposure following the dermal application of 0.05% cream would be 45 µg/kg, assuming human percutaneous absorption of approximately 5% and the use in a 50 kg person of 90 g of cream in one day.The approximate LD₅₀ values are shown in the following table:

High oral doses of 1 g/kg were well tolerated in both the mouse and rat. The only (reversible) changes observed were a slowing in growth rate and microscopically-evident cortical depletion of the thymus of animals killed 3 days after dosing.

Subcutaneous doses of fluticasone propionate at 1 g/kg were administered to mice and rats. Animals progressively lost condition and body weight and the effects seen were thymic depletion and various lesions associated with a compromised immune system. In addition, gastric steroid ulcers were seen.These observed changes are the expected response to glucocorticoid therapy. The lack of reversible thymic effects in subcutaneously-dosed animals is almost certainly due to the deposition and leaching of insoluble steroid from the injection site.

When given intravenously to rats at a dose of 2 mg/kg, the only changes seen were slightly subdued behaviour immediately after treatment and reversible thymic involution.

Chronic Toxicity

Subacute toxicity studies were conducted in adult and juvenile rats for periods up to 35 days and in Beagle dogs for periods up to 44 days. Fluticasone propionate was administered as follows:

Clinical observations were similar for all routes of administration in both species. These consisted of reduced weight gain and general loss of condition. Inhalation studies in the dog resulted in clinical signs associated with the administration of a potent glucocorticoid and were consistent with the symptoms of Canine CushingsÕ Syndrome.

Changes typical of glucocorticoid overdosage were seen in both haematological and clinical chemistry parameters. Effects were seen on the red cell parameters and a characteristic leukopenia resulting from a lymphopenia accompanied by a neutrophilia. Endogenous cortisol and corticosterone were depressed in dogs and rats respectively.

Microscopic pathology was again consistent with the administration of a potent glucocorticoid showing thymic and adrenal atrophy, lymphoid depletion in rats and dogs and glycogenic vacuolation of the liver in dogs.

There were no specific effects on the maturation of juvenile rats after subcutaneous dosing.

The application of a cream formulation containing 0.05% fluticasone propionate and an ointment containing 0.05, 0.10 or 0.20% w/w fluticasone propionate to the abraded skin of rats for up to 35 days did not compromise the healing of damaged areas of skin. Some skin thinning was observed at the site of application. Expected glucocorticoid effects, namely reduced body weight gain and slight changes in hematology and clinical chemistry, were observed. However, absorption of flutica-sone propionate was of a low order as no significant differences were observed in the corticosterone levels between treated and control animals.

Fluticasone propionate ointment was well tolerated following daily applications to the skin of the rat at dose levels of 0.05, 0.10 and 0.20% w/w for 26 weeks. Thinning of the skin at the application sites, due to slight to moderate thinning of the dermal collagen, together with loss of fat was observed.

Daily dermal administration of 0.8% w/w of fluticasone propionate ointment under occlusion for up to 6.5 hours per day to Beagle dogs for 26 weeks was also well tolerated. A single papilloma was observed at the treatment site in each of 2 dogs at the high dose level. This may have been a consequence of local immunosup-pression. Three dogs at the high dose level showed moderate to large diffuse corneal opacities at the end of treatment. These animals had intercurrent ocular infections during the study. Increased susceptibility to ocular infection in these dogs may have occurred in part as a result of the recognised immunosuppressive effect of corticosteroids.

Mutagenicity

Fluticasone propionate did not induce gene-mutation in prokaryotic microbial cells and there was no evidence of toxicity or gene-mutational activity in eukaryotic Chinese hamster cells in vitro. The compound did not induce point-mutation in the Fluctuation assay, and did not demonstrate gene-convertogenic activity in yeast cells. No significant clastogenic effect was seen in cultured human peripheral lymphocytes in vitro and fluticasone propionate was not demonstrably clastogenic in the mouse micronucleus test when administered at high doses by oral or subcutaneous routes. Furthermore, the compound did not delay erythroblast division in bone marrow.

Reproduction and Teratology

Subcutaneous studies in the mouse and rat at 150 and 100 µg/kg/day respectively, revealed maternal and foetal toxicity characteristic of potent glucocorticoid compounds, including reduction in maternal weight gain, embryonic growth retardation, increased incidences of retarded cranial ossification, and of omphalo-coele and cleft palate in rats and mice, respectively. In the rabbit, subcutaneous doses of 30 µg/kg/day and above were incompatible with sustained pregnancy. This is not unexpected since rabbits are known to be particularly sensitive to glucocorticoid treatment.

Following oral administration of fluticasone propionate up to 300 µg/kg to the rabbit, there were no maternal effects nor increased incidence of external, visceral, or skeletal foetal defects. A very small fraction ( < 0.005%) of the dose crossed the placenta following oral administration to rats (100 µg/kg /day) and rabbits (300 µg/kg/day).

Carcinogenicity

No treatment related effects were observed on the type or incidence of neoplasia in an 80 week dermal oncogenicity study in mice treated with a 0.05% fluticasone propionate ointment, in an 18 month oral (gavage) study in mice administered fluticasone propionate at dose levels of up to 1 mg/kg/day. In a lifetime (2 years) snout-only inhalation study in rats, at dose levels of up to 57 µg/kg/day, there was an increase in the incidence of tumours in the mammary gland, liver and pancreas. These were not considered as evidence of tumorogenic effect of fluticasone propionate based on the absence of statistical support of an increase in incidence and the historical tumour data.

Local Tolerance

Little or no irritancy was observed following the application of ointment formulations containing up to 0.1% fluticasone propionate either as daily doses for 35 days to the skin of the rat or as single dose, non-occluded or occluded tests on intact or abraded guinea pig skin. Negligible irritancy was produced following the application of fluticasone propionate cream or ointment (containing up to 0.05% w/w flutica-sone propionate) formulations as single occluded doses on intact and abraded skin and as a series of 4 daily repeated non-occluded doses on the intact skin of the guinea pig.

A single application of 0.05% w/w fluticasone propionate ointment or cream to abraded skin sites on rats did not affect the normal wound healing process. Micronised fluticasone propionate was considered to be non-irritating in the rabbit eye when assessed using a modified Draize test and in the guinea pig split adjuvant test for evaluating contact sensitivity, results were completely negative.
