Flunisolide nasal solution is available in an aqueous solubilized form, which delivers 25 pg per spray. The total daily adult dose for flunisolide from the nasal spray is 200 to 400 pg. Flunisolide inhalation aerosol for pulmonary delivery is a microcrystalline suspension in a chlorofluorocarbon propellant that delivers 250 pg per metered spray. The total daily adult inhalation dose for flunisolide is 1,000 pg. Doses exceeding 2,000 pg/day need to be monitored for FIFA suppression.

Beclomethasone dipropionate, triamcinolone acetonide, budesonide, flunisolide, and mometasone furoate are available as nasal sprays for the topical treatment of allergic rhinitis. They are effective at doses (one or two sprays one, two, or three times daily) that in most patients result in plasma levels that are too low to influence adrenal function or have any other systemic effects. 

Topical administration to the nose The safety of nasal glucocorticoids in the treatment of allergic rhinitis has been reviewed (434,435). The local application of glucocorticoids for seasonal or perennial rhinitis often results in systemic adverse effects. The use of nasal sprays containing a glucocorticoid that has specific topical activity (such as beclomethasone dipropionate or flunisolide) seems to reduce the systemic adverse effects, but they can nevertheless occur, even to the extent of suppression of basal adrenal function in children (436). Local adverse effects include Candida infection, nasal stinging, epistaxis, throat irritation (437), and, exceptionally, anosmia (438). 

In 1987 the xanthine derivative theophylline was the most commonly used medication in the treatment of asthma, followed by / 2-agonists, such as albuterol or ter-butaline, and inhaled corticosteroids, for example budesonide or flunisolide. Today, the most frequently used medication is inhaled / 2-agonists and it is expected that these therapy patterns have shifted toward greater use of inhaled corticosteroids [4, 5], Nevertheless, whether used alone or in combination with other therapies, corticosteroids do not consistently abrogate airway inflammation in patients with asthma common side effects associated with this type of drug are increased heart rate, nervousness, tremors, nasal irritation, nausea, and headaches [8, 10, 11],... 

Nasal sprays are available as squeeze bottles, which would not be expected to give reproducible dosing. They are also available as metered-dose devices, which would be expected to give more reproducible dosing, as a mechanical actuation delivers a pre-determined volume to the patient. Thus the dose of drag received by the patient will be dependent on the concentration of drag in the formulation. Commercial examples of metered-dose sprays include Syntaris, Beconase and Rhinocort which deliver flunisolide, beclomethasone and budesonide respectively. 

As a nasal spray, flunisolide is effective in allergic rhinitis in clinical use [32-34], and their protective effects in patients with bronchial asthma have also been studied. The efficacy and safety of a new metered-dose inhaler of flunisolide has recently been reported [35].

Corticosteroids — Beclomethasone dipropionate (17) aerosol has been tested extensively clinically. It is used prophylactically (400 fig per day), not therapeutically, in the treatment of chronic asthma, particularly in children.52 An evaluation of the drug has been published.53 One of the most important clinical advantages is that 1 7 effectively can replace oral corticosteroids in steroid-dependent patients and avoid many of the adverse effects of adrenal suppression.52,54 Most patients with impaired adrenal function due to oral corticosteroids show recovery of adrenal function within 6 months.55 The combination of 17 and disodium cromoglycate (DSCG) showed no additive therapeutic effects.5 Flunisolide (18), when administered as a nasal spray for 4 weeks during the hay fever season in 51 patients, showed significant symptomatic improvement with no systemic steroid effects observed.57...
