Pharmaceutical Excipients in Solid Oral Dosage Forms
Solid oral dosage forms such as tablets and capsules remain the most widely used drug delivery systems, and pharmaceutical excipients are fundamental to their success. These substances ensure manufacturability, stability, and effective drug release while maintaining patient safety.
Fillers and diluents are among the most commonly used excipients in tablets. They provide bulk to formulations where the active ingredient is present in small quantities. This allows tablets to reach a manageable size for handling and dosing accuracy.
Binders play a crucial role in tablet formation by holding powder particles together. Without binders, tablets would lack mechanical strength and break apart during handling or transportation. Proper binder selection ensures durability without compromising disintegration.
Disintegrants enable tablets to break down after ingestion, allowing the active ingredient to dissolve and become available for absorption. This function is critical for ensuring therapeutic effectiveness and predictable drug action.
Lubricants and glidants improve manufacturing efficiency by preventing powders from sticking to equipment and enhancing flow properties. These excipients reduce production issues while maintaining consistent tablet quality.
Through precise excipient selection, solid dosage forms achieve reliability, safety, and patient acceptance.
