The wet granulation process is a cornerstone of modern pharmaceutical manufacturing, especially in the formulation of oral solid dosage forms such as tablets and capsules. Among the various granulation techniques used—dry granulation, direct compression, and wet granulation—the wet method remains the most widely adopted due to its significant advantages in improving powder flow, compressibility, and content uniformity. This article explores in detail the advantages of the wet granulation process, particularly in the context of enhancing product quality, operational efficiency, and regulatory compliance in pharmaceutical production.
