Inhaled corticosteroids are medications used to treat asthma. They are taken by using an inhaler. This medication should be taken consistently so that it decreases inflammation in the airways of your lungs and prevents asthma flare-ups. Inhaled corticosteroids are considered the most effective long term usage medication for control and management of asthma. Depending upon the severity of your asthma, your physician may combine an inhaled corticosteroid with a long-acting beta-2 agonist to treat your condition. Oral and intravenous corticosteroids may be required for acute asthma flare-ups or for severe symptoms.
Corticosteroids have been used to control MS relapses for decades. Data on the effectiveness of these medications in MS comes from four randomized, placebo-controlled studies of intravenous and oral methylprednisolone. Altogether, these studies included 74 people with MS who received corticosteroid treatment and 66 who received placebo. Corticosteroid treatment with methylprednisolone resulted in greater speed of recovery from exacerbation compared with placebo. However, treatment did not decrease the risk of future relapses or decrease the progression of disability.
