์์ฉ ๊ธฐ์ : Dirlotapide selectively inhibits **microsomal triglyceride transfer protein (GMTP)** in the enterocytes of the gut. * **Lipid Blockade:** Inhibits GMTP โ blocks the assembly and release of lipoproteins into systemic circulation โ reduces dietary fat absorption. * **Satiety Signaling:** The accumulation of lipids within enterocytes triggers the release of **Peptide YY (PYY)** into the systemic circulation โ signals the central nervous system to decrease appetite and induce satiety. * **Action Site:** Primarily acts locally in the gut. Systemic blood levels do not directly correlate with efficacy, but rather with systemic toxicity.

- Weight Loss Phase (First 14 days) ยท 0.01 mL/kg (0.05 mg/kg) ยท PO ยท q24h ยท 14 days ยท Initial assessment required prior to therapy.
- Weight Loss Phase (Days 15 to 28) ยท 0.02 mL/kg (0.1 mg/kg) ยท PO ยท q24h ยท 14 days ยท Double the initial dose volume.
- Weight Loss Phase (Subsequent Months) ยท Adjust volume monthly to maintain a target percent weight loss of โฅ 0.7% per week. Max dose: 0.2 mL/kg (0.09 mL/lb) ยท PO ยท q24h ยท Until desired weight is reached ยท If target not met: increase dose by 100% (first adjustment) or 50% (subsequent adjustments). If food consumption is greatly reduced, withhold 1-2 days.
- Weight Management Phase ยท Adjust dose volume by -50%, 0%, or +50% based on last month's weight loss, then +/- 25% in subsequent months. Max dose: 0.2 mL/kg (0.09 mL/lb) ยท PO ยท q24h ยท 3 months recommended ยท Establish optimal food intake and physical activity to stabilize body weight.

**Toxicity Profile:** Oral doses of 0.5, 1, and 2 mL/kg (2.5X, 5X, and 10X the maximum labeled dose) administered to normal weight Beagles for two weeks were generally tolerated. **Clinical Signs of Overdose:** * Vomiting and diarrhea * Anorexia and lethargy * Transient elevations in liver enzymes (transaminases) *Note: No histopathologic evidence of hepatic necrosis was observed at these doses.*
