7. Product details

1. Why am I taking MAXOR?

MAXOR contains the active ingredient omeprazole.
MAXOR belongs to a group of medicines called proton pump inhibitors. It works by reducing the amount of acid made by the stomach, to give relief of symptoms and allow healing to take place. This does not stop food being digested in the normal way.

Gastro-oesophageal reflux disease (GORD)

MAXOR is used to treat and prevent gastro-oesophageal reflux disease (GORD) from returning.

This can be caused by "washing back" (reflux) of food and acid from the stomach into the oesophagus (food pipe).

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

MAXOR is also taken to help stop reflux oesophagitis coming back or relapsing.

Peptic Ulcers

MAXOR is used to treat peptic ulcers.

Depending on the position of the peptic ulcer, it is called 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 from the stomach.

Ulcers can be caused in part by too much acid being made in the stomach.

MAXOR is also used to help stop gastric or duodenal ulcers coming back.

Peptic Ulcers Associated with Helicobacter pylori Infection

MAXOR is used to treat peptic ulcers associated with helicobacter pylori infection.

Most people who have a peptic ulcer also have a bacterium called Helicobacter pylori in their stomach. MAXOR can be taken with antibiotics to treat this infection. The antibiotics are used to kill the bacteria while MAXOR allows the ulcers to heal.

You may need further treatment with antibiotics.

Peptic Ulcers Associated with Non-steroidal Anti-inflammatory Drugs (NSAIDs)

MAXOR is used to treat peptic ulcers associated with non-steroidal anti-inflammatory drugs (NSAIDs).

Some peptic ulcers are caused by taking medicines called non-steroidal anti-inflammatory drugs (NSAIDs), a type of medicine used to treat pain or inflammation.

MAXOR is also used to heal and prevent ulcers associated with NSAIDs.

Zollinger-Ellison Syndrome

MAXOR is used to treat a rare condition called Zollinger-Ellison syndrome.

In this condition, the stomach produces very large amounts of acid, much more than in ulcers and reflux disease.

Your doctor may have prescribed MAXOR for another reason. Ask your doctor if you have any questions about why MAXOR has been prescribed for you.

MAXOR is not recommended for use in children, as there is no experience with MAXOR capsules in children.

There is no evidence that MAXOR is addictive.

2. What should I know before I take MAXOR?

4 Clinical Particulars

4.9 Overdose

Rare reports have been received of overdosage with omeprazole. In the literature doses of up to 560 mg have been described and occasional reports have been received when single oral doses have reached up to 2400 mg omeprazole (120 times the usual recommended clinical dose). Nausea, vomiting, dizziness, abdominal pain, diarrhoea and headache have been reported from overdosage with omeprazole. Also apathy, depression and confusion have been described in single cases. The symptoms described in connection to omeprazole overdosage have been transient, and no serious clinical outcome due to omeprazole has been reported. The rate of elimination was unchanged (first order kinetics) with increased doses and no specific treatment has been needed. In suspected cases of overdosage treatment should be supportive and symptomatic.
For information on the management of overdosage, contact the Poison Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.3 Preclinical Safety Data

Genotoxicity. Omeprazole has been subjected to a battery of in vitro and in vivo genotoxicity tests to examine the mutagenic, clastogenic and DNA damaging potential of the drug. The in vitro assays include the Ames test, mouse lymphoma TK locus forward mutation assay and a chromosome aberration test in human lymphocytes. The in vivo tests were a chromosome aberration test in mouse bone marrow, an alkaline elution/rat liver DNA damage assay and two mouse micronucleus tests.
No evidence of significant genotoxicity was seen in these tests.
Carcinogenicity. In a two year carcinogenicity study in rats, omeprazole at daily doses of 13.8, 44.0 and 140.8 mg/kg/day produced gastric ECL cell hyperplasia and carcinoid tumours in a dose related manner in both male and female rats. The incidence of these effects was markedly higher in female rats.
The same effects were seen in an additional 2 year study in female rats at daily doses of 1.7, 3.4 and 13.8 mg/kg/day. A no effect dose was not established in female rats in the dose ranges studied.
In mice, a 78 week carcinogenicity study was performed according to relevant regulatory and scientific standards. No gastric ECL cell carcinoids were seen. However, longer-term studies have not been performed in this species.
Hypergastrinaemia, ECL cell hyperplasia and gastric carcinoids have also been produced in the rat by other treatments or procedures not related to omeprazole. These include the following:
a) Exogenous gastrin infusion. Subcutaneous infusion of gastrin 17 has resulted in a significant hyperplasia of ECL cells following treatment for one month.
b) H2-receptor antagonists. In rats administered 2 g/kg/day of ranitidine in their diet over 106 weeks, argyrophilic cell hyperplasia was observed in 37% of the animals and gastric carcinoids were found in 19% of the treated group.
c) Surgical resection of the acid producing oxyntic mucosa. In rats in whom 75% of the stomach corpus was surgically removed, 26 of 75 animals developed ECL cell carcinoids during the 124 week study.
These findings show that the development of ECL cell carcinoids in the rat is directly related to hypergastrinaemia rather than a direct effect of omeprazole on the ECL cell.
Omeprazole may also affect other cells in the gastrointestinal tract (for example, G cells) either directly or by inducing sustained hypochlorhydria but this possibility has not been extensively studied.
