Many people with chronic lung disease periodically require a short-term burst of steroid pills or syrups to decrease the severity of acute attacks and prevent an emergency room visit or hospitalization. A burst may last two to seven days and may not require a gradually decreasing dosage. For others, a burst may need to continue for several weeks with a gradually decreasing dosage. You may experience a few mild side effects such as increased appetite, fluid retention, moodiness and stomach upset. These side effects are temporary and typically disappear after the medicine is stopped.
Cells of the zona fasciculata and zona reticularis lack aldosterone synthase (CYP11B2) that converts corticosterone to aldosterone, and thus these tissues produce only the weak mineralocorticoid corticosterone. However, both these zones do contain the CYP17A1 missing in zona glomerulosa and thus produce the major glucocorticoid, cortisol. Zona fasciculata and zona reticularis cells also contain CYP17A1, whose 17,20-lyase activity is responsible for producing the androgens, dehydroepiandosterone (DHEA) and androstenedione. Thus, fasciculata and reticularis cells can make corticosteroids and the adrenal androgens, but not aldosterone.
