Inhaled corticosteroids uses

There is some evidence that quadrupling the maintenance dose of inhaled corticosteroids, 73 or treating with a high dose of inhaled corticosteroids, 74 ,  75 ,  76 reduces the severity of asthma flare-ups. For patients taking inhaled corticosteroid/long-acting beta 2 agonist combinations, this can be achieved by adding a separate high-dose inhaled corticosteroid inhaler to the patient’s usual maintenance treatment for 7–14 days. This strategy may be useful for patients who experience clinically important side-effects with oral corticosteroids, but may not be suitable for patients who cannot afford the extra medicine or who experience hoarseness with high dose inhaled corticosteroid.

    There is concern that P-glycoprotein mediated efflux contributes to steroid resistance. Therefore, this study examined bidirectional corticosteroid transport and induction capabilities for P-glycoprotein (P-gp) to understand which of the systemic and inhaled corticosteroids interacted with P-gp to the greatest extent. Hydrocortisone, prednisolone, prednisone, methylprednisolone, and dexamethasone represented systemically active drugs, while fluticasone propionate, beclomethasone dipropionate, ciclesonide and budesonide represented inhaled corticosteroids. Aldosterone and fludrocortisone represented mineralocorticoids. All drugs were detected using individually optimised HPLC protocols. Transport studies were conducted through Caco-2 monolayers. Hydrocortisone and aldosterone had efflux ratios below , while prednisone showed a P-gp mediated efflux ratio of only compared to its active drug, prednisolone, with an efflux ratio of . Dexamethasone and beclomethasone had efflux ratios of and respectively, while this increased to for methylprednisolone. Fluticasone showed an efflux ratio of . Protein expression studies suggested that all of the inhaled corticosteroids were able to induce P-gp expression, from to 2 times control levels. Most of the systemic corticosteroids had higher passive permeability (>20×10(-6) cm/s) compared to the inhaled corticosteroids (>5×10(-6) cm/s), except for budesonide, with permeability similar to the systemic corticosteroids. Inhaled corticosteroids are not transported by P-gp to the same extent as systemic corticosteroids. However, they are able to induce P-gp production. Thus, inhaled corticosteroids may have greater interactions with other P-gp substrates, but P-gp itself is less likely to influence resistance to the drugs.

    Poor Growth: While poor growth can result from ICS, poorly controlled asthma can also lead to poor growth in children. In general, low and medium doses of ICS are potentially associated with small, non-progressive but reversible declines in growth of children. As a result, you and your asthma provider should not only carefully monitor growth, but try to use the lowest possible dose that gets good control of your child's asthma. You must weigh the potential benefits of good asthma control with the small but real possible side effect of slowed growth.

    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.
