  1. 1. Methylprednisolone Shilpa Garg
  2. 2. Introduction Glucocorticoids are a class of steroid hormones  characterised by an ability to bind with the glucocorticoid receptor (GR) and trigger similar effects.  Glucocorticoids are distinguished from mineralocorticoids and sex steroids by their specific receptors, target cells, and effects.  Glucocorticoids have potent anti-inflammatory and immunosuppressive properties  Glucocorticoids are produced in the adrenal glands.  Mineralocorticoids are a class of steroid hormones characterised by their similarity to aldosterone and their influence on salt and water balance.
  3. 3. Comparative Steroid Potencies Glucocorticoid Mineralocorticoid Duration of action (t1/2 in Name potency potency hours) Hydrocortisone (Cortisol) 1 1 8 Cortisone acetate 0.8 0.8 oral 8, intramuscular 18+ Prednisone 3.5-5 0.8 16-36 Prednisolone 4 0.8 16-36 Methylprednisolone 5-7.5 0.5 18-40 Dexamethasone 25-80 0 36-54 Betamethasone 25-30 0 36-54 Triamcinolone 5 0 12-36 8 puffs 4 times a day Beclometasone equals 14 mg oral - - prednisone once a day Fludrocortisone acetate 15 200 - Deoxycorticosterone acetate 0 20 - (DOCA) Aldosterone 0.3 200-1000 -
  4. 4. Introduction Pharmacologically speaking, there  isn't a lot of difference between methylprednisolone and prednisolone. Methylprednisolone is slightly more potent in glucocorticoid activity than prednisolone, so it's thought to be stronger than prednisolone
  5. 5. Methylprednisolone Methylprednisolone is a potent  corticosteroid with an anti- inflammatory activity at least five times that of hydrocortisone.  An enhanced separation of glucocorticoid and mineralocorticoid effect results in a reduced incidence of sodium and water retention.
  6. 6. Pharmacokinetics Corticosteroids are absorbed from the  gastro-intestinal tract.  In the circulation they are extensively bound to plasma proteins and are metabolised mainly in the liver but also in the kidney and are excreted in the urine.
  7. 7. Indications Methylprednisolone is indicated for conditions requiring glucocorticoid activity such as:  Endocrine disorders ◦ Primary and secondary adrenal insufficiency ◦ Congenital adrenal hyperplasia Rheumatic disorders  ◦ Rheumatoid arthritis ◦ Juvenile chronic arthritis ◦ Ankylosing spondylitis
  8. 8. Indications Collagen diseases/arteritis  ◦ Systemic lupus erythematosus ◦ Systemic dermatomyositis (polymyositis) ◦ Rheumatic fever with severe carditis ◦ Giant cell arteritis/ polymyalgia rheumatica Dermatological diseases  ◦ Pemphigus vulgaris
  9. 9. Indications Allergic states  ◦ Severe seasonal and perennial allergic rhinitis ◦ Drug hypersensitivity reactions ◦ Serum sickness ◦ Allergic contact dermatitis ◦ Bronchial asthma
  10. 10. Indications Ophthalmic diseases  ◦ Anterior uveitis (iritis, iridocyclitis) ◦ Posterior uveitis ◦ Optic neuritis Respiratory diseases  ◦ Pulmonary sarcoid ◦ Fulminating or disseminated tuberculosis (with appropriate antituberculous chemotherapy) ◦ Aspiration of gastric contents
  11. 11. Indications Neoplastic diseases  ◦ Leukaemia (acute and lymphatic) ◦ Malignant lymphoma Gastrointestinal diseases  ◦ Ulcerative colitis ◦ Crohn's disease
  12. 12. Indications Haematological disorders  ◦ Idiopathic thrombocytopenic purpura ◦ Haemolytic anaemia (autoimmune) Miscellaneous  ◦ Tuberculous meningitis (with appropriate anti-tuberculous chemotherapy) ◦ Transplantation
  13. 13. Dosage & Administration Recommended initial daily dosage  Rheumatoid arthritis ◦ severe 12-16 mg ◦ moderately severe 8-12 mg ◦ moderate 4-8 mg ◦ children 4-8 mg Systemic dermatomyositis: 48 mg  Systemic lupus erythematosus: 20-100 mg  Acute rheumatic fever: 48 mg until ESR  normal for one week.  Allergic diseases: 12-40 mg
  14. 14. Dosage & Administration Bronchial asthma up to 64 mg single  dose/alternate day up to 100 mg maximum.  Ophthalmic diseases:12-40 mg  Haematological disorders and leukaemias: 16-100 mg  Malignant lymphoma: 16-100 mg  Ulcerative colitis: 16-60 mg
  15. 15. Dosage & Administration Crohn's disease up to 48 mg per day  in acute episodes.  Organ transplantation up to 3.6 mg/kg/day  Pulmonary sarcoid: 32-48 mg on alternate days.  Giant cell arteritis/polymyalgia rheumatica: 64 mg  Pemphigus vulgaris: 80-360 mg
  16. 16. Contraindications Methylprednisolone is contraindicated  where there is ◦ known hypersensitivity to components ◦ and in systemic infection unless specific anti-infective therapy is employed.
  17. 17. Warnings & Precautions Pregnancy  The ability of corticosteroids to cross the placenta varies between individual drugs, however, methylprednisolone does cross the placenta.  Administration of corticosteroids to pregnant animals can cause abnormalities of foetal development including cleft palate, intra-uterine growth retardation and effects on brain growth and development.
  18. 18. Warnings & Precautions Lactation  Corticosteroids are excreted in small amounts in breast milk, however, doses of up to 40 mg daily of methylprednisolone are unlikely to cause systemic effects in the infant.  Infants of mothers taking higher doses than this may have a degree of adrenal suppression, but the benefits of breastfeeding are likely to outweigh any theoretical risk.
  19. 19. Side Effects Bloody or black, tarry stools   Confusion, excitement, restlessness, a false sense of well-being  Eye pain, decreased or blurred vision, or bulging eyes  Fever, sore throat, sneezing, cough, or other signs of infection, wounds that will not heal  Frequent passing of urine  Increased thirst  Irregular heartbeat  Menstrual problems  Muscle cramps or weakness
  20. 20. Side Effects Nausea, vomiting   Pain in hips, back, ribs, arms, shoulders, or legs  Pain, redness, swelling, or infection at the injection site  Rounding of face  Skin problems, acne, thin and shiny skin  Stomach pain  Swelling of feet or lower legs  Unusual bruising, pinpoint red spots on the skin  Unusual tiredness or weakness  Weight gain or weight loss  Mental depression, mood swings, mistaken feelings of self-importance or of being mistreated
