HYDROCORTISONE AND ACETIC ACID vs ORAPRED
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Hydrocortisone is a corticosteroid that binds to the glucocorticoid receptor, leading to increased lipocortin synthesis, inhibition of phospholipase A2, decreased arachidonic acid release, and reduced prostaglandin and leukotriene production; it also suppresses cytokine expression and immune cell migration. Acetic acid is a weak acid that lowers local pH, inhibiting bacterial and fungal growth and disrupting microbial cell membranes.
Prednisolone is a corticosteroid that binds to the glucocorticoid receptor, leading to modulation of gene expression and suppression of inflammatory cytokines, immune responses, and adrenal function.
Instill 5 drops into affected ear(s) twice daily for 7-10 days; or as directed by physician.
5-60 mg orally once daily or divided as 5-15 mg every 4-12 hours; adjust based on response and condition.
