EXEM FOAM KIT vs PROCTOFOAM HC
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
The active ingredient in EXEM FOAM KIT is diclofenac, a nonsteroidal anti-inflammatory drug (NSAID) that inhibits cyclooxygenase (COX-1 and COX-2) enzymes, thereby reducing prostaglandin synthesis. This leads to anti-inflammatory, analgesic, and antipyretic effects.
Hydrocortisone is a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive actions by binding to cytoplasmic glucocorticoid receptors, which then translocate to the nucleus and modulate gene expression, leading to suppression of inflammatory mediators (e.g., prostaglandins, leukotrienes) and inhibition of immune cell migration. Pramoxine is a local anesthetic that reversibly blocks sodium ion channels in nerve membranes, thereby inhibiting initiation and conduction of sensory nerve impulses.
Apply to affected area twice daily. Exemestane is an aromatase inhibitor; this is a topical formulation.
Rectal aerosol foam: 1 applicatorful (6.5% pramoxine HCl / 1% hydrocortisone) rectally 2-3 times daily. Maximum 4 weeks.

Terminal elimination half-life is approximately 5–6 hours in patients with normal renal function; prolonged in hepatic impairment.
The terminal elimination half-life of hydrocortisone is approximately 1.5-2 hours. After topical application to the rectal mucosa, systemic absorption is minimal, resulting in a half-life comparable to that of endogenous cortisol, with clinical effects lasting about 6-8 hours.
Primarily fecal via biliary elimination (>90% as unchanged drug and metabolites); renal excretion accounts for <10%.
Hydrocortisone is metabolized in the liver, primarily to inactive metabolites (tetrahydrocortisone and tetrahydrocortisol). Less than 1% of the dose is excreted unchanged in urine. Fecal excretion is negligible.
