Laropiprant

Introduction

Laropiprant is a selective prostaglandin D2 receptor antagonist used primarily in combination with niacin (vitamin B3) to reduce flushing—a common side effect of niacin therapy. It is typically prescribed to patients undergoing treatment for high cholesterol or dyslipidemia, where niacin helps raise HDL (good cholesterol) and lower LDL (bad cholesterol) and triglycerides. By blocking the flushing response caused by niacin, Laropiprant helps improve patient compliance and comfort during long-term cholesterol treatment.

Uses of Laropiprant

• Used in combination with niacin for cholesterol management
• Reduces flushing associated with niacin intake
• Supports therapy in patients with mixed dyslipidemia
• Helps manage high triglyceride levels

How Laropiprant works

Laropiprant works by selectively blocking the prostaglandin D2 (PGD2) receptor subtype 1 (DP1), which is responsible for vasodilation and flushing triggered by niacin. By inhibiting this receptor, it significantly reduces the skin redness, warmth, and tingling that patients often experience after taking niacin.

Benefits of Laropiprant

• Minimizes niacin-induced skin flushing
• Improves tolerance to cholesterol-lowering niacin therapy
• Supports cardiovascular health by enhancing niacin adherence
• Offers relief from discomfort without reducing niacin efficacy

How to take Laropiprant

Laropiprant is typically taken in combination with niacin as a fixed-dose tablet. It should be taken once daily with food, preferably in the evening. Do not crush or chew the tablet. Follow the dosage as prescribed by your healthcare provider and do not stop the medication without consulting them.
