A-Fenac SR 100 mg is a sustained-release formulation of diclofenac sodium, manufactured by ACME Laboratories Ltd. in Bangladesh. This nonsteroidal anti-inflammatory drug (NSAID) is designed to provide prolonged therapeutic effects with a single daily dose, making it suitable for managing chronic inflammatory conditions. The tablet is enteric-coated, ensuring that the active ingredient is released in the intestines rather than the stomach, which helps reduce gastrointestinal irritation.
