Introduction to Corticosteroids - Classes of corticosteroids: cortisol, cortisone, corticosterone, aldosterone - Effects of glucocorticoids: carbohydrate, fat, and protein metabolism, anti-inflammatory, immunosuppressive, anti-proliferative, vasoconstrictive - Effects of mineralocorticoids: regulation of electrolyte and water balance - Medical uses: treatment of various conditions, synthetic pharmaceutical drugs with corticosteroid-like effects, different types of corticosteroids
Pharmacology and Pharmacogenetics of Corticosteroids - Corticosteroids act as agonists of the glucocorticoid receptor and/or the mineralocorticoid receptor - Some corticosteroids may have progestogenic activity and produce sex-related side effects - Patients' response to inhaled corticosteroids may be influenced by genetic variations in genes such as CHRH1 and TBX21 - Not all asthma patients respond to corticosteroids and some are corticosteroid resistant - Using the control inhaler as needed may work as effectively as daily use in improving asthma control and reducing corticosteroid medicine intake
Adverse Effects and Risks of Corticosteroids - Severe amoebic colitis, neuropsychiatric effects, cardiovascular effects - Metabolic effects: redistribution of body fat, muscle wasting, hyperglycemia, diabetes mellitus - Long-term use: steroid-induced osteoporosis, decreased height in children with asthma - Gastrointestinal effects: colitis, peptic ulceration - Chronic use: cataract, glaucoma
Uses and Benefits of Corticosteroids - Treatment of optic neuritis - Suppression of immune reactions for allergies - Management of inflammation and swelling - Relief of symptoms in conditions like asthma, arthritis, and dermatitis - Supportive therapy for certain types of cancer
Administration and Precautions of Corticosteroids - Routes of administration: topical, inhaled, oral, systemic, combination therapy - Side effects: increased vulnerability to infections, teratogenic effects, potential for topical steroid addiction, short-term use in children - Contraindications: active infections, uncontrolled high blood pressure, recent vaccination with live vaccines, pregnancy, hypersensitivity - Administration methods: oral tablets or capsules, inhalers, topical creams or ointments, injections, eye drops or ointments - Precautions and monitoring: regular monitoring of blood pressure, blood sugar levels, bone density, gradual tapering of doses, lowest effective dose, avoiding sudden discontinuation, close monitoring for adverse effects
