Metyrapone is used for the medical control of hypercortisolism in Cushing's syndrome (ACTH dependent or independent). The aim for medical treatment is to achieve pre-operative control of hypercortisolism, or for control of residual disease persisting post-operatively (TSS, adrenalectomy). It is not for long term definitive treatment/cure, only as an adjunct (surgery is the aim for cure in most causes of Cushing's syndrome). Metyrapone hence acts by inhibiting adrenal steroidogenesis. One side effect is hirsutism (in women) because of the excess androgen precursors created. The other commonly used agent for medical treatment of Cushing's is ketoconazole (an anti-fungal agent). This does not exhibit the side effect of hirsutism.
Initial dose based on previous asthma drug therapy and disease severity; 100 mcg via oral inhalation once daily is the usual recommended starting dose for patients not on an inhaled corticosteroid. After 2 weeks of therapy, if asthma symptoms are uncontrolled, increase dose to 200 mcg via oral inhalation once daily. Max: 200 mcg once daily. Administer at the same time each day. The maximum beneficial effect may not be achieved for up to 2 weeks or longer after starting treatment. Titrate to the lowest effective dose once asthma stability is achieved.
COPD is a chronic condition that is always there. That's why it is important to take ADVAIR DISKUS twice a day, every day, to help improve lung function so you can breathe better.* Your results may vary. ADVAIR DISKUS is approved for adults with COPD, including chronic bronchitis, emphysema, or both. ADVAIR DISKUS is not for, and should not be used to treat, sudden symptoms of COPD. ADVAIR DISKUS won't replace a rescue inhaler. You should only take 1 inhalation of ADVAIR DISKUS twice a day. Higher doses will not provide additional benefits.
