4. CLINICAL PARTICULARS

4.1    Therapeutic indications

Bezafibrate is indicated as an adjunct to diet and other non-pharmacological treatment (e.g. exercise, weight reduction) for the following:

-    Treatment of severe hypertriglyceridaemia with or without low HDL cholesterol.

-    Mixed hyperlipidaemia when a statin is contraindicated or not tolerated.

4.2    Posology and method of administration

Posology

Adults

The recommended dosage is one tablet (200 mg Bezafibrate) taken three times daily equivalent to 600 mg bezafibrate. Occasionally gastrointestinal symptoms may occur. In susceptible patients, slowly increasing dosage over 5 to 7 days may help to avoid such symptoms.

Older people

In older people there is a physiological reduction of the renal function with age. Bezafibrate dosage should be adjusted based on serum creatinine clearance values (see Patients with renal impairment below).

Patients with renal impairment

In dialysis patients the use of bezafibrate is contraindicated.

In patients with renal insufficiency the dose should be adjusted according to serum creatinine levels or creatinine clearance as shown in the following table.

Serum creatinine (micro mol/l)


Creatinine clearance (ml/min)_


Dosage

(tablets/day)


Up to 135 136 - 225 226 - 530 Over 530


Over 60 60 - 40 40 - 15 Less than 15


3

2

1 every 1 or 2 days Contraindicated


The response to therapy is normally rapid, although a progressive improvement may occur over a number of weeks. Treatment should be withdrawn if an adequate response has not been achieved within 3 to 4 months.

Paediatric population

At present there is inadequate information regarding an appropriate dosage in children and adolescents.

Method of administration

Bezafibrate Film-coated Tablets are for oral use.

Tablets should be swallowed whole with a sufficient amount of fluid after each meal.

4.3    Contraindications

Bezafibrate is contraindicated in patients with:

•    hypersensitivity to the active substance or to any of the excipients listed in section 6.1

•    hypersensitivity to other fibrates

•    significant hepatic disease (other than fatty infiltration of the liver associated with raised triglycerides values)

•    gall bladder disease with or without cholelithiasis

•    patients with nephrotic syndrome and severe renal failure (serum creatinine > 530 pmol/l; creatinine clearance <15ml/min) and patients undergoing dialysis (see section 4.2)

•    combination therapy of bezafibrate with HMG CoA reductase inhibitors (statins) in patients with predisposing factors for myopathy (see sections 4.4 and 4.5)

•    known photoallergic or phototoxic reactions to fibrates.

4.4    Special warnings and precautions for use

Bezafibrate should be used as an adjunct to diet and measures such as physical activity, weight loss and adequate treatment of other metabolic disorders (e.g. diabetes, gout).

Secondary causes of dyslipidaemia, such as uncontrolled type 2 diabetes mellitus, hypothyroidism, nephritic syndrome, dysproteinemia, obstructive liver disease, pharmacological treatment, alcoholism should be adequately treated before bezafibrate therapy is initiated.

Bezafibrate and other fibrates may cause myopathy, manifested as muscle weakness or pain, often accompanied by a considerable increase in creatine kinase (CPK). In isolated cases severe muscle damage (rhabdomyolysis) has been observed. The risk of rhabdomyolysis may be increased when higher than recommended doses of bezafibrate are used, most frequently in the presence of impaired renal function and in patients with predisposing factors for myopathy, (including renal impairment, older (aged >65 years), personal or familial history of hereditary muscular disorders and previous history of muscular toxicity with a fibrate or other lipid lowering drugs, hypothyroidism, severe infection, trauma, surgery, disturbances of hormone or electrolyte imbalance and a high alcohol intake).

Bezafibrate should be used with caution in combination with HMG CoA reductase inhibitors as the combination of HMG CoA inhibitors and fibrates has been shown to increase the incidence and severity of myopathy. Patients should be informed of symptoms and monitored for signs of myopathy and increased CPK activity and combination therapy discontinued if signs of myopathy develop. Combination therapy should not be used in patients with predisposing factors for myopathy (see sections 4.3 and 4.5).

Bezafibrate alters the composition of bile. There have been isolated reports of the development of gallstones.

As bezafibrate could cause cholelithiasis appropriate diagnostic procedures should be performed if cholelithic signs or symptoms occur (see section 4.8).

Since oestrogens may lead to a rise in lipid levels, the prescribing of bezafibrate in patients taking oestrogens or oestrogen-containing contraceptives must be critically considered on an individual basis.

When bezafibrate is given in combination with anion-exchange resins (e.g. colestyramine), the two drugs should be taken at least 2 hours apart.

Bezafibrate Film-coated Tablets contain lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.

4.5    Interaction with other medicinal products and other forms of interaction

Care is required in administering bezafibrate to patients taking coumarin-type anticoagulants, the action of which may be potentiated. The dosage of anticoagulant should be reduced by up to 50 per cent and then readjusted by regular monitoring of blood coagulation.

As bezafibrate improves glucose utilisation the action of antidiabetic medication, including insulin, may be potentiated. Hypoglycaemia has not been observed although increased monitoring of the glycaemic status may be warranted for a brief period after introduction of bezafibrate.

Should combined therapy with an ion-exchange resin be considered necessary, there should be an interval of at least 2 hours between the intake of the resin and bezafibrate, otherwise the absorption of bezafibrate may be impaired.

In isolated cases, a pronounced though reversible impairment of renal function (accompanied by a corresponding increase in serum creatinine level) has been reported in organ transplant patients receiving immunosuppressant therapy and concomitant bezafibrate. Accordingly, renal function should be closely monitored in these patients and, in the event of relevant significant changes in laboratory parameters, bezafibrate, should if necessary, be discontinued.

MAO-inhibitors (with hepatotoxic potential) should not be administered together with bezafibrate.

Interaction between HMG CoA reductase inhibitors and fibrates may vary in nature and intensity depending on the combination of the administered drugs. A pharmacodynamic interaction between these two classes of drugs may, in some cases, also contribute to an increase in the risk of myopathy (see section 4.3 and 4.4) for specific dose recommendations of statins refer also to the SPC of the relevant product.

4.6    Fertility, pregnancy and lactation

Pregnancy

There are limited data from the use of bezafibrate in pregnant women. Animal studies are insufficient with respect to reproductive toxicity. The potential risk for humans is unknown. Bezafibrate is not recommended during pregnancy and in women of childbearing potential not using contraception.

Breast-feeding

There is insufficient information on the excretion of bezafibrate or its metabolites in human milk. A risk to the suckling child cannot be excluded. A decision must be made whether to discontinue breastfeeding or to discontinue/abstain from bezafibrate therapy taking into account the benefit of breastfeeding for the child and the benefit of therapy for the woman.

4.7    Effects on ability to drive and use machines

Bezafibrate has been shown to cause dizziness and can have a minor to moderate effect on the ability to drive or use machines. Patients should not drive or use machines if they are affected.

4.9 Overdose

No specific effects of acute overdose are known. Rhabdomyolysis has occurred. There is no specific antidote. Thus appropriate symptomatic therapy is recommended in cases of overdose. In cases of rhabdomyolysis, bezafibrate must be stopped immediately and renal function carefully monitored.

5. PHARMACOLOGICAL PROPERTIES

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Lipid modifying agents, plain Fibrates, ATC Code: C10AB02 Mechanism of action

Bezafibrate lowers elevated blood lipids (triglycerides and cholesterol). Elevated VLDL and LDL are reduced by treatment with bezafibrate, whilst HDL-levels are increased. The activity of triglyceride lipases (lipoprotein lipase and hepatic lipoprotein lipase) involved in the catabolism of triglyceride-rich lipoproteins is increased by bezafibrate. In the course of the intensified degradation of triglyceride-rich lipoproteins (chylomicrons, VLDL), precursors for the formation of HDL are formed which explains an increase in HDL. Furthermore, cholesterol biosynthesis is reduced by bezafibrate, which is accompanied by a stimulation of the LDL receptor-mediated lipoprotein catabolism.

Studies have shown bezafibrate to be effective in treating hyperlipidaemia in patients with diabetes mellitus. Some cases showed a beneficial reduction in fasting blood glucose.

Significant reductions in serum fibrinogen levels have been observed in hyperfibrinogenaemic patients treated with bezafibrate.

There is evidence that treatment with fibrates may reduce coronary heart disease events but they have not been shown to decrease all cause mortality in the primary or secondary prevention of cardiovascular disease.

Clinical efficacy and safety No data available.

5.2 Pharmacokinetic properties

Absorption

Bezafibrate is rapidly and almost completely absorbed from the standard film-coated tablet formulation. A peak plasma concentration of about 8mg/l is reached after 1-2 hours following a single 200 mg dose in healthy volunteers.

Distribution

The protein-binding of bezafibrate in serum is approximately 95%. The apparent volume of distribution is 17 litres.

Biotransformation

50% of the administered bezafibrate dose is recovered in the urine as unchanged drug and 20% in the form of glucuronides.

Elimination

Elimination is rapid with excretion almost exclusively renal. 95% of the activity of 14C-labelled drug is recovered in the urine and 3% in the faeces within 48 hours. 50% of the applied dose is recovered in the urine as unchanged drug and 20% in the form of glucuronides.

The rate of renal clearance ranges from 3.4 to 6.0 l/h. The elimination half-life is in the order of 1-2 hours.

Pharmacokinetics in special populations:

Pharmacokinetic investigations in older people suggest that elimination may be delayed in cases of impaired liver function. Liver disease (except fatty liver) is a contraindication for the use of bezafibrate (see section 4.3).

In older patients, there is a physiological reduction of the renal function with age. Bezafibrate dosage should be adjusted based on the serum creatinine and creatinine clearance values as indicated in the above table. (See section 4.2)

The elimination of bezafibrate is reduced in patients with impaired renal function and dosage adjustments are necessary to prevent drug accumulation and toxic effects.

Because of its high protein binding, bezafibrate cannot be dialysed (cuprophane filter). The use of bezafibrate is contraindicated in dialysis patients.

5.3 Preclinical safety data

The chronic administration of a high dose of bezafibrate to rats was associated with hepatic tumour formation in females. This dosage was in the order of 30 to 40 times the human dosage. No such effect was apparent at reduced intake levels approximating more closely to the lipid-lowering dosage in humans.
