Nonsteroidal antiinflammatory drugs: Moderate Although some patients may need to be given corticosteroids and NSAIDs concomitantly, which can be done successfully for short periods of time without sequelae, prolonged concomitant administration should be avoided. Corticosteroids can have profound effects on sodium-potassium balance; NSAIDs also can affect sodium and fluid balance.

Monitor serum potassium concentrations; potassium supplementation may be necessary. In addition, NSAIDs may mask fever, pain, swelling and other signs and symptoms of an infection; use NSAIDs with caution in patients receiving immunosuppressant dosages of corticosteroids. The Beers criteria recommends that this drug combination be avoided in older adults; if coadministration cannot be avoided, provide gastrointestinal protection.

The use of potassium salts or supplements would be expected to alter the effects of corticotropin on serum potassium levels. Therefore, magnesium sulfate; potassium sulfate; sodium sulfate should be administered with caution during concurrent use of medications that lower the seizure threshold such as systemic corticosteroids. Potassium-sparing diuretics: Minor The manufacturer of spironolactone lists corticosteroids as a potential drug that interacts with spironolactone.

Intensified electrolyte depletion, particularly hypokalemia, may occur. However, potassium-sparing diuretics such as spironolactone do not induce hypokalemia. In fact, hypokalemia is one of the indications for potassium-sparing diuretic therapy. Therefore, drugs that induce potassium loss, such as corticosteroids, could counter the hyperkalemic effects of potassium-sparing diuretics.

Sodium Chloride: Moderate Concomitant use of systemic sodium chloride, especially at high doses, and corticosteroids may result in sodium and fluid retention. Sodium Phenylbutyrate: Moderate The concurrent use of corticosteroids with sodium phenylbutyrate may increase plasma ammonia levels hyperammonemia by causing the breakdown of body protein. Patients with urea cycle disorders being treated with sodium phenylbutyrate usually should not receive regular treatment with corticosteroids.

Sodium Phosphate Monobasic Monohydrate; Sodium Phosphate Dibasic Anhydrous: Moderate Use sodium phosphate cautiously with corticosteroids, especially mineralocorticoids or corticotropin, ACTH, as concurrent use can cause hypernatremia.

Vincristine Liposomal: Moderate Use sodium phosphate cautiously with corticosteroids, especially mineralocorticoids or corticotropin, ACTH, as concurrent use can cause hypernatremia. Voriconazole: Moderate Monitor for potential adrenal dysfunction with concomitant use of voriconazole and beclomethasone. In patients taking corticosteroids, voriconazole-associated CYP3A4 inhibition of their metabolism may lead to corticosteroid excess and adrenal suppression.

Corticosteroid exposure is likely to be increased. Vorinostat: Moderate Use vorinostat and corticosteroids together with caution; the risk of QT prolongation and arrhythmias may be increased if electrolyte abnormalities occur.

Corticosteroids may cause electrolyte imbalances; hypomagnesemia, hypokalemia, or hypocalcemia and may increase the risk of QT prolongation with vorinostat. Frequently monitor serum electrolytes if concomitant use of these drugs is necessary. The effect of corticosteroids on warfarin is variable.

There are reports of enhanced as well as diminished effects of anticoagulants when given concurrently with corticosteroids; however, limited published data exist, and the mechanism of the interaction is not well described. High-dose corticosteroids appear to pose a greater risk for increased anticoagulant effect. In addition, corticosteroids have been associated with a risk of peptic ulcer and gastrointestinal bleeding.

Beclomethasone is a corticosteroid that exhibits anti-inflammatory, antipruritic, vasoconstrictive effects as well as limiting allergic responses. The specific mechanisms of action depend on the route of administration and condition being treated.

Treatment of asthma: Clinical effects in asthma include a reduction in bronchial hyperresponsiveness to allergens, a decreased number of asthma exacerbations, and an improvement in FEV1, peak-flow rate, and respiratory symptoms. Because corticosteroid effects take several hours to days to become clinically noticeable, they are ineffective for primary treatment of severe acute bronchospastic attacks or for status asthmaticus. Inhaled corticosteroids have no bronchodilatory properties.

In the treatment of asthma, orally inhaled corticosteroids block the late phase allergic response to allergens. Mediators involved in the pathogenesis of asthma include histamine, leukotrienes the slow-releasing substance of anaphylaxis, SRS-A , eosinophil chemotactic factor of anaphylaxis ECF-A , neutrophil chemotactic factor NCF , cytokines, hydroxyeicosatetraenoic acids, prostaglandin-generating factor of anaphylaxis PGF-A , prostaglandins, major basic protein, bradykinin, adenosine, peroxides, and superoxide anions.

Different cell types are responsible for the release of these mediators including airway epithelium, eosinophils, basophils, lung parenchyma, lymphocytes, macrophages, mast cells, neutrophils, and platelets. Corticosteroids inhibit the release of these mediators, attenuate mucous secretion and eicosanoid generation, up-regulate beta-receptors, promote vasoconstriction, and suppress inflammatory cell influx and inflammatory processes. Treatment of allergies: Intranasal beclomethasone inhibits the activity of several cell types e.

Clinically, symptoms such as rhinorrhea and postnasal drip, nasal congestion, sneezing, and pharyngeal itching are reduced. In vitro data have shown that beclomethasonemonopropionate the active entity displays a binding affinity for the glucocorticoid receptor that is approximately 13 times that of dexamethasone, 6 times that of triamcinolone acetonide, 1.

Beclomethasone is administered by oral or nasal inhalation. The major route of elimination of inhaled beclomethasone appears to be via metabolism.

Three major metabolites of beclomethasone are formed via hepatic cytochrome P 3A-family catalyzed biotransformation: beclomethasonemonopropionate BMP, the most active metabolite , beclomethasonemonopropionate BMP and beclomethasone BOH. For the oral inhalation route, some metabolism occurs in the lungs before entering the systemic circulation; the lung tissues metabolize beclomethasone rapidly to BMP and more slowly to BOH.

The mean elimination half-life of BMP is 2. Irrespective of the route of administration injection, oral, or inhalation , beclomethasone and its metabolites are excreted predominantly in the feces.

Nasal inhalation absorption: After nasal inhalation, beclomethasone is absorbed through the nasal mucosa, with minimal amounts absorbed systemically. The onset of action of the drug typically occurs within 24 hours, but full effects can take as long as 1 to 4 weeks to be apparent. The mean Cmax of the major and most active metabolite, BMP, occurs roughly 0. The Cmax of BMP increases proportionally with dose in the normal dosage range.

Oral inhalation absorption Qvar Redihaler : After oral inhalation, the onset of action of the drug typically occurs within 24 hours, but full effects can take as long as 3 to 4 weeks to be apparent.
