MELFIAT-105 vs OBY-TRIM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Selective serotonin reuptake inhibitor (SSRI); potentiates serotonergic activity in the CNS by inhibiting reuptake of serotonin at the presynaptic neuronal membrane.
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.
105 mg orally once daily in the morning.
Oral: 1 capsule (phentermine 18.75 mg / chlorpheniramine 6.25 mg) twice daily, 30 minutes before meals.

The terminal elimination half-life is approximately 4-6 hours, supporting twice-daily dosing in clinical practice.
Terminal half-life is approximately 20–30 hours in adults with normal renal function. This allows for once-daily dosing in most patients.
Approximately 90% of an administered dose is excreted renally as unchanged drug and metabolites, with the remainder eliminated via biliary/fecal routes.
Primarily renal (90% as unchanged drug and metabolites), with about 10% biliary/fecal. In an acidic urine, elimination half-life increases.
