Yes, you can use Avilin Gastro on pebbles on the gallbladder.
The preparation has a local effect – it coats the upper part of the digestive tract, is not absorbed into the general circulation and does not affect the work of the gallbladder. It works by creating a gel barrier that absorbs acidic content. This barrier remains on the surface of the gastric contents and, as a result, prevents it from flowing back into the esophagus. Alginate gel protects the gastric and esophageal mucosa from the adverse effects of acidic gastric contents.

It is important to keep min. A 2-hour interval between this preparation and other drugs. Due to the barrier formed, the preparation may hinder the absorption of other drugs, hence the necessary interval of at least 2 hours.
