Raciper belongs to family of medications called proton pump inhibitors (PPIs). Raciper blocks enzyme called H,K ATPase (enzyme that pumps gastric acid), thus inhibiting gastric acid secretion.1 If you are interested in detailed mechanism of action, you should read this article

Because of such effects, this drug is used to treat:

  • Zollinger-Ellison syndrome
  • Gastroesophageal reflux disease (GERD)
  • Duodenal ulcer disease
  • Gastric ulcer disease
  • Heartburn

Beside using Raciper, you'll need to make some lifestyle changes if you want to improve ulcer healing. Try to avoid eating large meals, spicy food (such as chili peppers) and high-fat foods. Also, the consumption of alcohol is strictly forbidden. Try to eat 5-7 small sized meals during the day. Milk and diary products are also recommended.


Raciper should be avoided if you have ever had allergic reaction to the Raciper or other proton pump inhibitors.

Raciper should be used with extreme precautions in patients with following conditions:

  • Hepatic function impairment
  • Renal function impairment
  • Hypomagnesemia (condition in which blood magnesium levels are lower than normal)
  • Osteoporosis (condition in which bones are weaker and more prone to fractures). Studies have shown that long-term use of this drug is associated with increased risk of bone fractures.2

Raciper safety in pregnang woman and breastfeeding mothers

There are no reliable data regarding Raciper safety during pregnancy. It is mostly recommended to make lifestyle modifications in order to relieve symptoms of heartburn, GERB or ulcers.

There are no studies about Raciper use in breastfeeding mothers. For these reasons, breastfeeding should be avoided while on Raciper therapy.

Recommended dosage

It is important to remember that Raciper is most effective if taken on an empty stomach (especially if taken in the morning).

Long-term use of Raciper may cause bone fractures, vitamin B12 deficiency and mineral deficiencies. Raciper should not be used in patients under the age of 12.

Initial dose of Raciper is 20 mg once a day (on an empty stomach). In severe conditions, dose of Raciper may be increased to 40 mg in divided doses (20 mg in the morning and 20 mg before you go to bed).
