MELFIAT vs OBY-TRIM
Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Melfiat is a sympathomimetic amine that acts as an anorectic agent. Its mechanism of action involves stimulating the release of norepinephrine and dopamine from presynaptic nerve terminals in the hypothalamus, leading to suppression of appetite.
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.
1 to 2 tablets (75 to 150 mg mazindol) orally once daily with breakfast.
Oral: 1 capsule (phentermine 18.75 mg / chlorpheniramine 6.25 mg) twice daily, 30 minutes before meals.

Terminal elimination half-life is approximately 10-12 hours in healthy adults; may be prolonged in renal impairment.
Terminal half-life is approximately 20–30 hours in adults with normal renal function. This allows for once-daily dosing in most patients.
Primarily renal (70-80% as unchanged drug and metabolites), with ~20% eliminated via bile into feces.
Primarily renal (90% as unchanged drug and metabolites), with about 10% biliary/fecal. In an acidic urine, elimination half-life increases.
