Flovent Hfa
Flovent Hfa Uses, Dosage, Side Effects, Food Interaction and all others data.
Flovent Hfa propionate is a glucocorticoid with high topical anti-inflammatory potency, but a low HPA-axis suppressive activity after dermal administration. It, therefore, has a therapeutic index which is greater than most of the commonly available steroids. Flovent Hfa propionate has a high degree of selectivity for the glucocorticoid receptor. In vitro studies show that fluticasone propionate has a strong affinity for, and agonist activity at, human glucocorticoid receptors. This receptor is believed to be responsible for the anti-inflammatory properties of glucocorticoids.
Flovent Hfa propionate has weak affinity for 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. The half-life of the Flovent Hfa propionate glucocorticoid-receptor complex is approximately 10 hours.
Systemically, in vitro experiments show Flovent Hfa furoate activates glucocorticoid receptors, inhibits nuclear factor kappa b, and inhibits lung eosinophilia in rats. Flovent Hfa propionate performs similar activity but is not stated to affect nuclear factor kappa b. Flovent Hfa propionate as a topical formulation is also associated with vasoconstriction in the skin.

Uses
Flovent Hfa Propionate is used for the relief of inflammatory and pruritic manifestations of corticosteroid-responsive eczema or dermatitis.
Flovent Hfa is also used to associated treatment for these conditions: Asthma, Bronchostenosis, Skin discomfort, Moderate, severe Chronic Obstructive Pulmonary Disease (COPD)
How Flovent Hfa works
Flovent Hfa furoate and Flovent Hfa propionate work through an unknown mechanism to affect the action of various cell types and mediators of inflammation. In vitro experiments show Flovent Hfa furoate activating glucocorticoid receptors, inhibiting nuclear factor kappa b, and inhibiting lung eosinophilia in rats. Flovent Hfa propionate performs similar activity but is not stated to affect nuclear factor kappa b.
Dosage
Flovent Hfa dosage
Cream: Apply a thin layer of Flovent Hfa propionate cream to the affected skin areas once daily.
Ointment: Apply a thin layer of Flovent Hfa propionate Ointment to the affected skin areas twice daily.
Side Effects
The fluticasone propionate preparations are usually well tolerated; local burning and pruritus have been reported. If signs of hypersensitivity appear, application should be stopped immediately. Prolonged and intensive treatment with potent corticosteroid preparations may cause local atrophic changes in the skin such as thinning, striae, dilatation of the superficial blood vessels, hypertrichosis and hypopigmentation.
Secondary infection, particularly when occlusive dressings are used or when skin folds are involved and allergic contact dermatitis have also been reported with corticosteroid use. Exacerbation of the signs and symptoms of the dermatoses have been reported with corticosteroid use.
Prolonged use of large amounts of corticosteroids, or treatment of extensive areas, can result in sufficient systemic absorption to produce the features of hypercorticism. This effect is more likely to occur in infants and children, and if occlusive dressings are used. In infants, the napkin may act as an occlusive dressing.
Toxicity
Flovent Hfa furoate administered nasally may be associated with adrenal suppression or an increase in QTc interval though the association has not been well demonstrated in studies. Flovent Hfa furoate requires no dosage adjustment in renal impairment but must be used in caution in hepatic impairment due to the elimination mechanisms. Flovent Hfa furoate is not associated with carcinogenicity, mutagenicity, or impairment of fertility. There are no well controlled studies in pregnancy or lactation though animal studies have shown teratogenicity and hypoadrenalism in the offspring of treated mothers and other corticosteroids are known to be excreted in breast milk. Generally, there are no reported adverse effects with fluticasone in pregnancy. Pediatric patients should be given the lowest possible dose and monitored for reduction in growth velocity. There is insufficient evidence to determine whether geriatric patients respond differently to other patients. Systemic exposure may be 27-49% higher in Japanese, Korean, and Chinese patients compared to Caucasian patients. Caution should be exercised in these patients and the benefit and risk should be assessed before deciding on a treatment.
Flovent Hfa propionate's use in specific populations has not been well studied. Flovent Hfa propionate is not carcinogenic, mutagenic, or clastogenic, nor did it affect fertility in animal studies. Subcutaneous Flovent Hfa propionate has been shown to produce teratogenic effects in rats though oral administration does not. Generally, there are no reported adverse effects with fluticasone in pregnancy. Flovent Hfa propionate in human milk may cause growth suppression, effects on endogenous corticosteroid production, or other effects. Pediatric patients treated with Flovent Hfa propionate ointment experienced adrenal suppression. Geriatric patients treated with Flovent Hfa propionate did not show any difference in safety or efficacy compared to other patient groups, though older patients may be more sensitive to adverse effects. There is no difference in the clearance of Flovent Hfa propionate across genders or race. Patients with hepatic impairment should be closely monitored due to the elimination mechanism.
Precaution
Flovent Hfa propionate has a very low propensity for systemic absorption, nevertheless, prolonged application of high doses to large areas of body surface, especially in infants and small children might lead to adrenal suppression. Children may absorb proportionally larger amounts of topical corticosteroids and thus be more susceptible to systemic toxicity.
The face, more than other areas of the body, may exhibit atropic changes after prolonged treatment with potent topical corticosteroids. This must be borne in mind when treating severe eczema.
Appropriate antimicrobial therapy should be used whenever treating inflammatory lesions which have become infected. Any spread of infection requires withdrawal of topical corticosteroid therapy and systemic administration of antimicrobial agents. Bacterial infection is encouraged by the warm, moist conditions induced by occlusive dressing, and so the skin should be cleansed before a fresh dressing is applied.

Contraindication
Flovent Hfa propionate is contraindicated in Rosacea, Acne vulgaris, Peri-oral dermatitis, Primary cutaneous viral infections (e.g., herpes simplex, chicken pox), Hypersensitivity to any of the ingredients, Perianal and genital pruritus, etc. The use of Flovent Hfa propionate is not indicated in the treatment of primarily infected skin lesions caused by infection with fungi or bacteria and dermatoses in children under one year of age, including deramtitis and napkin eruptions.
Acute Overdose
Acute overdosage is very unlikely to occur, however, in case of cronic overdosage or misuse the features of hypercorticism may appear, and in this situation, as with any corticosteroid, application should be discontinued. Overdosage by ingestion of fluticasone propionate cream or ointment is extremely unlikely to occur due to the very low oral bioavailability of fluticasone propionate.
Storage Condition
Store below 30˚ C. Do not freeze.
