Zoton FasTabs

Print Friendly, PDF & Email

Generic Name: lansoprazole tablets
Product Name: Zoton FasTabs

Indication: What Zoton FasTabs is used for

Peptic ulcers

Zoton FasTabs is used to treat peptic ulcers in adults. Depending on the position of the ulcer, it is either a gastric or duodenal ulcer. A gastric ulcer occurs in the stomach. A duodenal ulcer occurs in the duodenum, which is the tube leading out of the stomach. Too much acid being made in the stomach can cause these ulcers.

Zoton FasTabs is also used to help stop duodenal ulcers from coming back.

Reflux oesophagitis

Zoton FasTabs is used to treat the symptoms of reflux oesophagitis or reflux disease in adults and in children from 6 to 17 years of age. This can be caused by backflow (reflux) of food and acid from the stomach into the food pipe or gullet, also known as the oesophagus.

Reflux can cause a burning sensation in the chest rising up to the throat, also known as heartburn.

Heartburn and stomach pain associated with reflux or peptic ulcer

Zoton FasTabs is used for the short-term treatment of heartburn and peptic ulcer symptoms in adults.

Peptic ulcers associated with Helicobacter pylori infection

Most people who have a peptic ulcer also have bacteria called Helicobacter pylori in their stomach.

Zoton FasTabs can be taken in conjunction with certain antibiotics to help eradicate Helicobacter pylori and let your peptic ulcer heal. However, it is possible that the antibiotics may not always get rid of Helicobacter pylori.

Ask your doctor if you have any questions about why Zoton FasTabs has been prescribed for you. Your doctor may prescribe this medicine for another reason.

There is no evidence that Zoton FasTabs is habit-forming. This medicine is available only with a doctor’s prescription.

Action: How Zoton FasTabs works

Zoton FasTabs contains lansoprazole, which is a type of medicine called a proton pump inhibitor (PPI). It works by decreasing the amount of acid the stomach makes, to give relief from the symptoms of excessive acid and allow healing to take place. This does not stop food being digested in the normal way.

Zoton FasTabs contain either 15 mg or 30 mg of lansoprazole as the active ingredient.

Zoton FasTabs also contain the inactive ingredients lactose monohydrate, microcrystalline cellulose, magnesium carbonate hydrate, low-substituted hyprolose, hyprolose, hypromellose, titanium dioxide, talc, mannitol, methacrylic acid – ethyl acrylate copolymer (1:1) 30 percent, polyacrylate dispersion 30 percent macrogol 8000, citric acid, glyceryl monostearate, polysorbate 80, triethyl citrate, iron oxide yellow (E172), iron oxide red (E172), crospovidone, magnesium stearate, strawberry flavour, aspartame.

Zoton FasTabs do not contain gluten, tartrazine or any other azo dyes.
