Which treatment is cytoprotective and forms a coating over ulcers?

The correct choice is based on the unique properties of the compounds in question. Sucralfate is specifically designed to be cytoprotective, which means it helps protect the gastrointestinal mucosa and promotes healing by forming a protective coating over existing ulcers. This mechanism involves sucralfate binding to ulcer sites and creating a gel-like barrier that shields them from stomach acid, bile, and other irritants, thus facilitating the healing process.

Pepto-Bismol, while primarily known for its antidiarrheal and mild antibacterial properties, also possesses some ulcer-protective qualities. It can provide a protective coating over the stomach lining and ulcers, helping to reduce irritation and promote healing in a similar fashion to sucralfate. This is why both treatments are recognized for their cytoprotective effects, leading to the conclusion that they can be classified together.

Antacids, on the other hand, work by neutralizing stomach acid, which provides symptomatic relief but does not create the protective coating mechanism that sucralfate does. Therefore, while they may alleviate pain and discomfort associated with ulcers, they do not contribute to the protective healing of ulcerated tissue. This distinguishes the coating and cytoprotective actions of sucralfate and the
