Inhaled corticosteroids are medications that improve breathing by depressing the lungs. It is most commonly used in clients with chronic asthma, meaning people have asthma symptoms more than 2 days a week. Asthma is characterized by chronic inflammation of the lungs, as well as exacerbations or asthma attacks, where certain triggers, such as viruses, allergens, stress, aspirin or other NSAIDs and exercise, lead to bronchial spasms and the production of mucus. , both of which make breathing difficult. As a result, the client experiences symptoms such as dyspnea, wheezing, chest tightness, and coughing. Inhaled corticosteroids help reduce the frequency of symptoms and prevent exacerbations. Inhaled corticosteroids may also be used in clients with chronic obstructive pulmonary disease, or COPD, to prevent exacerbations and slow the progression of the disease.
Adverse Effects Of Inhaled Corticosteroids
Currently, the most commonly used corticosteroids include fluticasone, beclomethasone, budesonide, and mometasone. These drugs are usually used as maintenance therapy to help fight against the lungs, and are often combined with inhaled bronchodilators, such as beta-2 agonists such as salmeterol, which provide rapid relief of symptoms by relaxing the smooth muscles of the airways. .

It has a rapid onset of action (5 – 30 minutes) and effectively reduces bronchoconstriction (for 4 – 6 hours) Prevents exercise- and cold-induced asthma. It has no anti-inflammatory effect and should not be used as a single (sole) treatment, except for occasional mild asthma.
Administration of β2-agonists with metered dose inhalation is an effective method of delivering the drug to the lungs. Some patients may have difficulty mastering breathing techniques, especially elderly patients and those with neurological or neurological conditions. In these patients, ventilatory support or other means of delivery (turbuhaler and disc) should be considered.
Salmeterol and formoterol provide 12-hour bronchodilation and prevent exercise-induced asthma. Formoterol is fast acting while salmeterol is slow acting. Add doses of LABA to patients with moderate to severe inhaled corticosteroid-intolerant disease than double the dose of inhaled corticosteroids to improve symptom control and reduce exacerbations.
9 The β2-agonist LABA controls asthma symptoms but has no anti-inflammatory effects. and should not be used as a sole treatment in asthma as this can lead to inflammation and worsen asthma attacks and other asthma-related complications. Mechanical ventilation (including ICS and LABA) provides better compliance and prevents the use of LABA as monotherapy.
Relevance Of Pharmacokinetics And Pharmacodynamics Of Inhaled Corticosteroids To Asthma
10 β2-agonists include β2-agonists that are well tolerated by most patients; Side effects may include tremors, nausea, and hypokalemia.
Inhaled corticosteroids (ICS) have an anti-inflammatory effect by reducing the number of mast cells, eosinophils, and lymphocytes and reducing cell function. As such, it reduces the production of cytokines by airway cells and prevents allergic reactions to allergens. Corticosteroids can also regulate the function of adrenergic receptors, thereby increasing the potency of β2-agonists.
Regular use of ICS in asthma patients improves lung function, reduces airway hyperresponsiveness, reduces asthma severity, and reduces asthma-related mortality. No other medication works as well as ICS for long-term asthma prevention. If properly prescribed and used in ICS therapy it will reduce or eliminate the use of oral steroids in severe asthma.
Beclomethasone, budesonide and fluticasone are usually prescribed (500 µg of beclomethasone is the usual starting dose). Alternative treatments should be considered when 1000 µg is prescribed and symptoms persist. The dose of ICS can be increased to 2000µg if the patient is still symptomatic despite the addition of LABA, leukotriene modifiers and theophylline.
Drugs Acting On The Respiratory System
Many side effects are associated with topical corticosteroid therapy, such as dysphonia (part of myopathy of small phonation muscles), mouth swelling, and coughing. Washing your mouth regularly and carefully after using a ventilator and assisted breathing can greatly reduce or eliminate the effects of these local side effects. When these side effects occur, they can be managed by reducing the dose (often reducing dysphonia) and oral antifungal therapy. However, some patients cannot tolerate the side effects and require other methods of drug control.
Adverse effects of inhaled corticosteroids are rare but occur in patients on many medications. These side effects include adrenal suppression, growth retardation in children, weight gain, glaucoma, cataracts, osteopenia, and thinning of the skin. Therefore, the lowest dose appropriate for disease control should always be used. Treatment should be reviewed periodically, perhaps every 3 months, if the disease is adequately controlled.
Leukotrienes have important effects in asthma, including vasodilation, mucus secretion, and inflammation. Leukotriene-modulating drugs include the leukotriene receptor antagonists montelukast and zafirlukast and the 5-lipoxygenase inhibitor zileuton. In asthma patients, leukotriene modifiers reduce symptoms, reduce the need for short-acting β-2-agonists, and prevent exercise-induced asthma. .
These drugs have mild anti-inflammatory effects, more so than inhaled corticosteroids. Patient responses to leukotriene replacement vary widely, with some patients showing a significant response and many others showing little or no response. Leukotriene replacement may be beneficial in patients with aspirin-induced asthma, exercise-induced asthma, and viral infections.
Clinical Pharmacology Of Corticosteroids
Due to the need to monitor liver function in patients treated with zileuton and the difficulty of maintaining compliance with this medication given four times a day, its use has been reduced. Leukotriene modifiers have been implicated in the development of Churg-Strauss syndrome in asthmatic patients receiving low doses of oral corticosteroids. It is not clear whether this is due to the lack of exposure to the previous Churg-Strauss syndrome or to the relationship between the drugs. Recently, neuropsychiatric side effects, including anxiety, depression, and suicidality, have been observed in patients taking leukotriene modifiers.
It is a mild bronchodilator with mild anti-inflammatory effects. Other possible side effects of theophylline include increased respiratory rate and increased respiratory function. Theophylline therapeutic serum concentration is between 5 and 12 µg/ml; Adverse effects such as tremors, tremors, headache, nausea, and vomiting may occur at higher doses if overdose. Very serious side effects, such as potentially fatal arrhythmias and seizures, may occur at concentrations above 20 µg/ml. Due to drug-drug interactions, this toxic effect can occur in patients who previously had stable serum theophylline but started taking interfering drugs, such as fluoroquinolone antibiotics (eg, ciprofloxacin).
Theophylline levels Theophylline levels should therefore be monitored and adjusted when patients are receiving other medications that may interfere with the metabolism of this agent. Because of these side effects, theophylline is not recommended as a first-line treatment for chronic asthma. It should be considered as an adjunctive treatment in patients who do not respond adequately to other treatments. The use of theophylline in severe asthma is not recommended because of its additional benefits as a bronchodilator and serious toxic effects.
Omalizumab, a recombinant monoclonal antibody that binds to the Fc portion of IgE antibodies, prevents the binding of lymphocytes and basophils. It is approved for use in patients with moderate to severe allergic asthma. Omalizumab is given as a single injection every 2 to 4 weeks depending on the patient’s weight and serum IgE. This should be reserved primarily for patients with severe, poorly controlled asthma that is unresponsive to other treatments.
Inhaled Steroid Disappoints For Covid 19
Suppression of the hypothalamic-pituitar-adrenal (HPA) axis: Doses of 7.5 mg prednisolone (or equivalent) given over 3 weeks are likely to suppress the HPA axis and should be tapered gradually over time. . Osteoporosis: the most common side effect, caused by inhibition of calcium absorption, bone loss and hormonal imbalance. Cushing’s disease: obesity, facial hair, hirsutism, acne, striae (thinning of the skin), bruising, weakness and weakness of peripheral nerves.
