OBESTIN-30 vs OBY-TRIM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
ObesTin-30 is a selective serotonin reuptake inhibitor (SSRI) that blocks serotonin reuptake, increasing serotonin levels in the synaptic cleft, which modulates appetite and mood.
OBY-TRIM is a combination of phentermine, a sympathomimetic amine anorectic that stimulates the hypothalamus to release norepinephrine, suppressing appetite, and a diuretic (often a thiazide) to reduce fluid retention.
30 mg subcutaneously once daily.
Oral: 1 capsule (phentermine 18.75 mg / chlorpheniramine 6.25 mg) twice daily, 30 minutes before meals.

Terminal elimination half-life is approximately 12 hours (range 10–14 hours) in patients with normal renal function; half-life may be prolonged to >24 hours in severe renal impairment (CrCl <30 mL/min).
Terminal half-life is approximately 20–30 hours in adults with normal renal function. This allows for once-daily dosing in most patients.
Renal excretion of unchanged drug accounts for approximately 60% of the administered dose; fecal elimination via biliary excretion accounts for approximately 30%, with the remainder as metabolites.
Primarily renal (90% as unchanged drug and metabolites), with about 10% biliary/fecal. In an acidic urine, elimination half-life increases.
