Role of Lubricants in Tablet Manufacturing: Function, Selection & Common Challenges Introduction In pharmaceutical solid dosage manufacturing, excipients play a crucial role in ensuring the quality, stability, and performance of the final product. Among them, lubricants are often under-discussed yet highly critical. A well-optimized lubricant system ensures smooth manufacturing, consistent product quality, and patient compliance. What are Lubricants? Lubricants are excipients added in small quantities (generally 0.25% – 3% w/w) at the final stage of granulation or blending. Their primary role is to reduce friction between the tablet surface and die wall during compression and ejection. Without proper lubrication, tablets may: - Stick to punches and dies - Show capping or lamination - Have weight variation issues - Cause machine downtime Functions of Lubricants Reduce Friction – Prevents sticking of tablets to punches and dies. Ensure Smooth Ejection – Reduces wear and tear on tooli...
