CROLOM vs OLOPATADINE HYDROCHLORIDE
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
CROLOM is a selective estrogen receptor modulator (SERM) that binds to estrogen receptors, blocking estrogen-mediated signaling in target tissues, thereby inhibiting growth of hormone-sensitive breast cancer cells.
Olopatadine hydrochloride is a selective histamine H1 receptor antagonist and mast cell stabilizer. It inhibits histamine release from mast cells and prevents histamine-induced effects such as increased vascular permeability and pruritus.
2 capsules (each containing 40 mg cromolyn sodium) orally 4 times daily, 30 minutes before meals and at bedtime.
One drop of 0.1% or 0.2% ophthalmic solution in each affected eye twice daily (every 6-8 hours) for 0.1%; once daily for 0.2%.

Terminal half-life 8-12 hours in normal renal function; extended to 20-30 hours in severe impairment

Renal: 70% unchanged; biliary/fecal: 30% as metabolites
Primarily renal excretion (60-70% unchanged), with minor biliary/fecal elimination (~30% as metabolites)
