Iota-Carrageenan from Marine Alga Prevents Naproxen-Induced Gastrointestinal Injury via Its Antioxidant and Anti-Inflammatory Activities.

Non-steroidal anti-inflammatory drugs (NSAIDs) are widely used in therapy due to their anti-inflammatory and analgesic properties. However, their clinical use is often associated with gastrointestinal complications. Thus, this study aimed to investigate the protective effect of a sulfated iota-carrageenan isolated from the marine alga (IC-Sf) against naproxen-induced gastrointestinal injury.
