What TACIDINE is used for
TACIDINE contains the active ingredient nizatidine.
TACIDINE belongs to a group of medicines called histamine (H2) antagonist or histamine
(H2) blockers. These medicines work by reducing the amount of stomach acid produced
which in turn reduces the pain and allows the ulcers and/or reflux disease to heal
in most people.
TACIDINE is used to treat both gastric ulcers and duodenal ulcers. A gastric ulcer
occurs in the stomach. A duodenal ulcer occurs in the duodenum (which is part of your
small intestine). The ulcers can be caused in part by too much acid being made in
TACIDINE is also used to help stop duodenal ulcers from coming back.
TACIDINE is also used to treat reflux oesophagitis or reflux disease. This is caused
by "washing back" (reflux) of food and acid from the stomach into the food pipe (also
known as the oesophagus).
Reflux causes burning sensation in the chest rising up to the throat (heartburn) and
most often occurs after eating or at night.
