Hi and thank you for asking HCM! I read your question above and my answer why the doctor has prescribed these drugs is: Sorliv is a medication used as an anti constipant. Neksium is a medication used to lower the production of gastric acid. Lesuride is an anti psycotic and in this case a procinetic drug used to increase the speed of gastric and bowel content transit. It improves dyspepsia and gastro-esophageal reflux. All these drugs are given to treat all the causes of your mother s gastric pain. I hope i have been clear enough. All the best for you!
