Pharmaceutical-Grade Nitrofurantoin SR Pellets for Sustained-Release Oral Formulations
Nitrofurantoin SR Pellets are multiparticulate pharmaceutical formulations designed for incorporation into oral dosage forms requiring a sustained-release profile. Nitrofurantoin, CAS Number 67-20-9, has the molecular formula C₈H₆N₄O₅ and molecular weight 238.16 g/mol.
Swapnroop offers Nitrofurantoin SR Pellets in 35% and 50% strengths, providing formulation flexibility for pharmaceutical manufacturers developing sustained-release multiparticulate products.
The pellet format provides a practical multiparticulate platform for applications such as capsule filling and other oral pharmaceutical dosage-form development. Release characteristics are controlled through the pellet formulation and coating system used during processing.
Nitrofurantoin is an established pharmaceutical active ingredient with CAS Number 67-20-9. The anhydrous material has a molecular formula of C₈H₆N₄O₅ and molecular weight of 238.16 g/mol. Nitrofurantoin may also exist as a monohydrate form, with CAS 17140-81-7.
For SR pellet manufacturing, the active ingredient is incorporated into a multiparticulate pellet system and processed to achieve the required sustained-release characteristics. Finished-pellet specifications should be evaluated according to the applicable product specification rather than directly applying API specifications to the finished pellets.
