Diclofenac Sodium Dual Release Pellets (CAS No: 15307-79-6)
Pharmaceutical-Grade Biphasic (Immediate + Sustained) Release Pellets for Oral Dosage Forms
Diclofenac Sodium Dual Release Pellets are pharmaceutical-grade multiparticulate pellets designed to deliver a biphasic drug-release profile — combining an immediate-release fraction for rapid onset with a sustained-release fraction for extended action, within a single capsule or tablet dosage form. This dual-release approach is commonly used to provide quicker analgesic/anti-inflammatory onset alongside a longer duration of action. Diclofenac Sodium has the molecular formula C₁₄H₁₀Cl₂NNaO₂ and a molecular weight of approximately 318.1 g/mol (source: PubChem).
A dual-release pellet system is typically formulated by blending two pellet populations — uncoated or minimally coated immediate-release pellets and polymer-coated sustained-release pellets — in a defined ratio, or by applying a partial functional coat to a single pellet population to achieve the combined release kinetics.
