  • PATIENT FACT SHEET (Deltasone)
    Prednisone PATIENT FACT SHEET (Deltasone) Prednisone (Deltasone) is part of a potent class of inflammatory conditions, including redness, anti-inflammatory agents, known as corticosteroids, swelling and pain. Prednisone is used to treat which are used to control inflammation of the rheumatoid arthritis, lupus, vasculitis, and many joints and organs. It is often used to treat a variety of other inflammatory diseases. WHAT IS IT? Dosing of prednisone varies widely depending on tablets take effect about 6 hours after taking the the state of the disease being treated. Doses used dose. Prednisone stops working soon after stopping in rheumatoid arthritis are commonly 5-10mg daily, the medication. If you have been taking prednisone while doses needed in lupus and vasculitis are often regularly for longer than 2 weeks, do not stop it 80mg daily, or sometimes higher. Prednisone usually suddenly. Instead, you should discuss a tapering HOW TO achieves its effect within 1-2 hours. The delayed release schedule with your physician. TAKE IT Most side effects are related to the dose administered medications, there is an increased risk of infection when and duration of treatment, so the goal is to use it at combining prednisone with other medications that the lowest effective dose for the shortest period of time affect your immune system. Additionally, when taking necessary. Some potential side effects include easy prednisone with NSAIDs (such as naproxen or ibuprofen), bruising, osteoporosis (or weakened bones), diabetes, there can be an increased risk of stomach ulcers.

    CELESTONE SYRUP PAGE 1 NDA 14-215/S-009, 015 CELESTONE® betamethasone syrup, USP DESCRIPTION CELESTONE Syrup, for oral administration, contains 0.6 mg betamethasone in each 5 mL. The inactive ingredients for CELESTONE Syrup include: alcohol (less than 1%), citric acid, FD&C Red No. 40, FD&C Yellow No. 6, flavors, propylene glycol, sodium benzoate, sodium chloride, sorbitol, sugar, and water. The formula for betamethasone is C22H29F05 and it has a molecular weight of 392.47. Chemically, it is 9-fluoro-11β,17,21-trihydroxy-16β-methylpregna-1,4-diene-3,20-dione and has the following structure: (Add structure) Betamethasone is a white to practically white, odorless crystalline powder. It melts at about 240°C with some decomposition. Betamethasone is sparingly soluble in acetone, alcohol, dioxane, and methanol; very slightly soluble in chloroform and ether; and is insoluble in water. CLINICAL PHARMACOLOGY Glucocorticoids, naturally occurring and synthetic, are adrenocortical steroids that are readily absorbed from the gastrointestinal tract. Naturally occurring glucocorticoids (hydrocortisone and cortisone), which also have salt- retaining properties, are used as replacement therapy in adrenocortical deficiency states. Their synthetic analogs, such as betamethasone, are primarily used for their anti-inflammatory effects in disorders of many organ systems. A derivative of prednisolone, betamethasone has a 16β­ methyl group that enhances the anti-inflammatory action of the molecule and reduces the sodium- and water-retaining properties of the fluorine atom bound at carbon 9. INDICATIONS AND USAGE Allergic states: Control of severe or incapacitating allergic conditions intractable to adequate trials of conventional treatment in asthma, atopic dermatitis, contact dermatitis, drug hypersensitivity reactions, perennial or seasonal allergic rhinitis, serum sickness.

  • Steroid Use in Prednisone Allergy Abby Shuck, Pharmd Candidate
    Steroid Use in Prednisone Allergy Abby Shuck, PharmD candidate 2015 University of Findlay If a patient has an allergy to prednisone and methylprednisolone, what (if any) other corticosteroid can the patient use to avoid an allergic reaction? Corticosteroids very rarely cause allergic reactions in patients that receive them. Since corticosteroids are typically used to treat severe allergic reactions and anaphylaxis, it seems unlikely that these drugs could actually induce an allergic reaction of their own. However, between 0.5-5% of people have reported any sort of reaction to a corticosteroid that they have received.1 Corticosteroids can cause anything from minor skin irritations to full blown anaphylactic shock. Worsening of allergic symptoms during corticosteroid treatment may not always mean that the patient has failed treatment, although it may appear to be so.2,3 There are essentially four classes of corticosteroids: Class A, hydrocortisone-type, Class B, triamcinolone acetonide type, Class C, betamethasone type, and Class D, hydrocortisone-17-butyrate and clobetasone-17-butyrate type. Major* corticosteroids in Class A include cortisone, hydrocortisone, methylprednisolone, prednisolone, and prednisone. Major* corticosteroids in Class B include budesonide, fluocinolone, and triamcinolone. Major* corticosteroids in Class C include beclomethasone and dexamethasone. Finally, major* corticosteroids in Class D include betamethasone, fluticasone, and mometasone.4,5 Class D was later subdivided into Class D1 and D2 depending on the presence or 5,6 absence of a C16 methyl substitution and/or halogenation on C9 of the steroid B-ring. It is often hard to determine what exactly a patient is allergic to if they experience a reaction to a corticosteroid.

Eugster1 Abstract Background: Little is known about the comparative effects of different glucocorticoids on the adrenal and growth hormone (GH) axes in children with congenital adrenal hyperplasia (CAH). We sought to compare the effects of hydrocortisone (HC), prednisone (PDN), and dexamethasone (DEX) in children with classic CAH and to investigate a potential role of pharmacogenetics. Methods: Subjects were randomly assigned to three sequential 6-week courses of HC, PDN, and DEX, each followed by evaluation of adrenal hormones, IGF-1, GH, and body mass index (BMI). Single nucleotide polymorphism (SNP) analysis of genes in the glucocorticoid pathway was also performed. Results: Nine prepubertal subjects aged 8.1 ± 2.3 years completed the study. Mean ACTH, androstenedione, and 17-hydroxyprogesterone (17-OHP) values were lower following the DEX arm of the study than after subjects received HC (p ≤ 0.016) or PDN (p ≤ 0.002). 17-OHP was also lower after HC than PDN (p < 0.001). There was no difference in IGF-1, GH, or change in BMI. SNP analysis revealed significant associations between hormone concentrations, pharmacokinetic parameters, and variants in several glucocorticoid pathway genes (ABCB1, NR3C1, IP013, GLCCI1).

  • Inhaled and Oral Corticosteroids
    Inhaled and Oral Corticosteroids Corticosteroids (steroids) are medicines that are used to treat many chronic diseases. Corticosteroids are very good at reducing inflammation (swelling) and mucus production in the airways of the lungs. They also help other quick-relief medicines work better. The steroids (corticosteroids) used to treat asthma and other chronic lung diseases are not the same as anabolic steroids, used illegally by some athletes for bodybuilding. Corticosteroids do not affect the liver or cause sterility. Does the Body Make Steroids? Corticosteroids are similar to cortisol, a hormone produced by the adrenal glands in the body. Cortisol is one of the body's own natural steroids. Cortisol is essential for life and well being. During stress, our bodies produce extra cortisol to keep us from becoming very sick. Normally the adrenal glands release cortisol into the blood stream every morning. The brain monitors this amount and regulates the adrenal function. It cannot tell the difference between its own natural cortisone and that of steroid medicines. Therefore, when a person takes high doses of steroids over a long time, the brain may decrease or stop cortisol production. This is called adrenal supression. Health care providers generally decrease a steroid dosage slowly to allow the adrenal gland to recover and produce cortisol at a normal level again. If you have been on steroids long- term do not stop taking them suddenly. Follow your doctor’s prescription. What are Some Steroid Medicines? Steroid medicines are available as nasal sprays, metered- dose-inhalers (inhaled steroids), oral forms (pills or syrups), injections into the muscle (shots) and intravenous (IV) solutions.
