1. Why am I using OLMERTAN COMBI TABLETS?

OLMERTAN COMBI TABLETS contains the active ingredient Olmesartan medoxomil and hydrochlorothiazide.

OLMERTAN COMBI TABLETS is used to treat high blood pressure which is sometimes called hypertension.

Everyone has blood pressure. This pressure helps push blood all around your body. Your blood pressure changes at different times of the day, depending on how busy or worried you are. You have hypertension (high blood pressure) when your blood pressure stays higher than is needed, even when you are calm and relaxed.

There are usually no symptoms of hypertension. The only way of knowing that you have hypertension is to have your blood pressure checked on a regular basis. If high blood pressure is not treated it can lead to serious health problems including stroke, heart disease and kidney failure.

How OLMERTAN COMBI TABLETS works

OLMERTAN COMBI TABLETS belongs to a group of medicines known as angiotensin-II receptor antagonists. Angiotensin-II is a substance produced in the body which causes blood vessels to tighten. OLMERTAN COMBI TABLETS blocks the action of angiotensin-II and therefore relaxes your blood vessels. This helps lower your blood pressure.

OLMERTAN COMBI TABLETS also contains a diuretic which reduces the amount of fluid in the body. This also helps to lower blood pressure.

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

OLMERTAN COMBI TABLETS is not addictive.

This medicine is available only with a doctor's prescription.

Things that would be helpful for your blood pressure

Some self help measures suggested below may help your condition. Talk to your doctor or pharmacist about these measures and for more information.

  • Alcohol - your doctor may advise you to limit your alcohol intake.
  • Weight: your doctor may suggest losing some weight to help lower your blood pressure and help lessen the amount of work your heart has to do. Some people may need a dietician's help to lose weight.
  • Diet: eat a healthy diet which includes plenty of fresh vegetables, fruit, bread (preferably wholegrain), cereals and fish. Also eat less sugar and fat (especially saturated fat) which includes sausages, fatty meats, full cream dairy products, biscuits, cakes, pastries, chocolates, chips and coconut. Monounsaturated and polyunsaturated fats from olive oil, canola oil, avocado and nuts are beneficial in small quantities.
  • Salt: your doctor may advise you to watch the amount of salt in your diet. To reduce your salt intake you should avoid using salt in cooking or at the table and avoid cooked or processed foods containing high sodium (salt) levels.
  • Exercise: regular exercise, maintained over the long term, helps to reduce blood pressure and helps get the heart fitter. Regular exercise also improves your blood cholesterol levels, helps reduce your weight and stress levels, and improves your sleep, mood and ability to concentrate. However, it is important not to overdo it. Walking is good exercise, but try to find a route that is reasonably flat. Before starting any exercise, ask your doctor about the best kind of programme for you.
  • Smoking - your doctor may advise you to stop smoking or at least cut down. There are enormous benefits to be gained from giving up smoking. There are many professionals, organisations and strategies to help you quit. Ask your doctor or pharmacist for further information and advice.

4 Clinical Particulars

4.9 Overdose

No specific information is available on the effects or treatment of Olmertan Combi overdosage. The patient should be closely monitored, and the treatment should be symptomatic and supportive. Management depends upon the time since ingestion and the severity of the symptoms. Activated charcoal may be useful in the treatment of overdosage. Serum electrolytes and creatinine should be monitored frequently. If hypotension occurs, the patient should be placed in a supine position, with salt and volume replacements given quickly.
The most likely manifestations of olmesartan overdosage are expected to be hypotension and tachycardia; bradycardia might also occur. Overdosage with HCTZ is associated with electrolyte depletion (hypokalaemia, hypochloraemia) and dehydration resulting from excessive diuresis. The most common signs and symptoms of overdosage are nausea and somnolence. Hypokalaemia may result in muscle spasm and/or accentuate cardiac arrhythmias associated with the concomitant use of digitalis glycosides or certain antiarrhythmic drugs.
No information is available regarding the dialysability of olmesartan or HCTZ.
For information on the management of overdose, contact the Poisons Information Centre on 131126 (Australia).

5 Pharmacological Properties

5.3 Preclinical Safety Data

Genotoxicity. Olmesartan medoxomil. Both olmesartan medoxomil and olmesartan tested negative in the in vitro Syrian hamster embryo cell transformation assay and showed no evidence of genetic toxicity in the Ames (bacterial mutagenicity) test. However, both were shown to induce chromosomal aberrations in cultured cells in vitro (Chinese hamster lung) and tested positive for thymidine kinase mutations in the in vitro mouse lymphoma assay. Olmesartan medoxomil tested negative in vivo for mutations in the intestine and kidney of a mutagenic susceptible mouse (MutaMouse) and for clastogenicity in mouse bone marrow (micronucleus test) at oral doses of up to 2,000 mg/kg/day. Olmesartan not tested in this mouse model. On balance, the weight-of-evidence indicates that olmesartan medoxomil does not pose a genotoxic risk at clinically relevant doses.
HCTZ. HCTZ was negative in several different assays of gene mutation and chromosomal aberration. However, positive test results were obtained in the in vitro CHO sister chromatid exchange (clastogenicity) assay and the mouse lymphoma (mutagenicity) assay at HCTZ concentrations of 43-1,200 microgram/mL.
Olmesartan medoxomil and HCTZ. Olmesartan medoxomil/HCTZ in a ratio of 20:12.5 was negative in the bacterial reverse mutation test up to the maximum recommended plate concentration for the standard assays.
As expected, positive clastogenicity responses were observed with either drug or the combination (40:12.5, 20:12.5, 10:12.5) in Chinese hamster lung cells but no synergistic clastogenicity was observed. However, the combination (20:12.5) was negative in the in vivo mouse micronucleus test at oral doses (1,935/1,209 mg/kg) that were likely to achieve high relative systemic exposure (> 33-700-fold based on AUC) to both components.
Carcinogenicity. The carcinogenic potential of olmesartan and HCTZ in combination has not been investigated.
Olmesartan medoxomil was not carcinogenic when administered by dietary administration to rats for up to 2 years. The highest dose tested (2,000 mg/kg/day) corresponded to a relative systemic exposure to olmesartan that was about 30 times that anticipated at the maximum recommended human dose (MRHD) of 40 mg/day (based on AUC). Two carcinogenicity studies conducted in mice, a 6-month gavage study in the p53 knockout mouse and a 6-month dietary administration study in the Hras2 transgenic mouse, at doses of up to 1,000 mg/kg/day (about 11 times anticipated clinical exposure to olmesartan at the MRHD, based on AUC in Hras2), revealed no evidence of a carcinogenic effect of olmesartan medoxomil.
Two-year feeding studies in mice and rats showed no evidence of carcinogenic potential for HCTZ in female mice at doses up to approximately 600 mg/kg/day, or in male and female rats at doses up to approximately 100 mg/kg/day. There was equivocal evidence for hepatocarcinogenicity in male mice treated with HCTZ at approximately 600 mg/kg/day.
