Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Metformin hydrochloride is a biguanide antihyperglycemic agent that improves glucose tolerance in patients with type 2 diabetes mellitus. It primarily decreases hepatic glucose production, decreases intestinal absorption of glucose, and improves insulin sensitivity by increasing peripheral glucose uptake and utilization.
PROCTOCORT (hydrocortisone acetate) is a corticosteroid that exerts anti-inflammatory, antipruritic, and vasoconstrictive effects. It binds to glucocorticoid receptors, modulating gene expression to inhibit phospholipase A2, reduce prostaglandin and leukotriene synthesis, and suppress cytokine production.
Locametz (gallium Ga 68 gozetotide) is administered intravenously at a dose of 3-5 mCi (110-185 MBq) as a single injection for PET imaging. No repeated dosing schedule is defined.
Rectal: One 30 mg suppository twice daily (morning and evening) for 2-3 weeks, then taper down as needed. Alternatively, 1% cream or ointment applied rectally 3-4 times daily.

Terminal elimination half-life of 14 hours (range 12-16 h); clinically, steady-state achieved after 3 days.
Terminal elimination half-life is approximately 3.5 hours (range 2-5 hours) for triamcinolone acetonide. Clinical context: short half-life supports BID or TID dosing in topical and rectal administration.
Primarily renal excretion (70% unchanged), with 20% fecal elimination via biliary secretion; 10% metabolized.
Primarily hepatic metabolism; renal excretion of metabolites accounts for ~60-70%, with ~15-25% excreted in feces via biliary elimination. Unchanged drug in urine is negligible (<1%).
