Avarin is a combined preparation containing alverine, a spasmolytic agent with a direct effect on the smooth muscle of the digestive tract. Alverine exerts fewer undesirable effects. The second component of the preparation is simethicone, which by a physical mechanism decreases the formation of gas and facilitates its removal from the digestive tract.
Thus provides relief from symptoms of irritable bowel syndrome as well as symptoms of abdominal discomfort like bloating, distention, fullness, pressure, pain and/or cramps.
