Corticosteroid use in asthma

Certain drugs such as troleandomycin (TAO), erythromycin ( Ery-Tab , EryPed 200), and clarithromycin ( Biaxin ) and ketoconazole ( Nizoral ) can reduce the ability of the liver to metabolize (breakdown) corticosteroids and this may lead to an increase in the levels and side effects of corticosteroids in the body. On the other hand, phenobarbital, ephedrine , phenytoin ( Dilantin ), and rifampin ( Rifadin , Rimactane ) may reduce the blood levels of corticosteroids by increasing the breakdown of corticosteroids by the liver. This may necessitate an increase of corticosteroid dose when they are used in combination with these drugs.

Data abstracted retrospectively from the charts at 11,359 clinic visits for 310 patients with SLE to the Montreal General Hospital were used to investigate the associations of recent corticosteroid dose and recent Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score with 8 CHD risk factors (total serum cholesterol, high-density lipoprotein [HDL] cholesterol, low-density lipoprotein cholesterol, apolipoprotein B [Apo B], triglycerides, systolic blood pressure [BP], body mass index, and blood glucose) and the aggregate estimate of 2-year CHD risk. Separate multivariable linear regression models estimated the mutually-adjusted effects of average daily corticosteroid dose and average SLEDAI score within the past year on the current level of each risk factor while adjusting for age, sex, cumulative damage score, disease duration, and, where appropriate, use of relevant medications.
