4.4. Special warnings and precautions for use

Liver effects

It is recommended that liver function tests should be performed before initiating treatment and periodically thereafter. Furthermore, patients who develop any signs or symptoms suggestive of liver injury should also have liver function tests performed.

Patients who develop increased transaminase levels should be monitored until the abnormalities resolve. Should an increase in transaminases (ALT or AST) of greater than 3 times the upper limit of normal (ULN) persist, reduction of dose or withdrawal of DEZZOLIP is recommended.

DEZZOLIP should be used with caution in patients who consume substantial quantities of alcohol and/or have a history of liver disease. Active liver disease or unexplained persistent transaminase elevations are contra-indications to the use of DEZZOLIP.

Skeletal Muscle

DEZZOLIP may affect the skeletal muscle and cause myalgia (generalised muscle pain), myositis (inflammation of muscle tissue), and myopathy (muscle aching or muscle weakness) that may progress to rhabdomyolysis, a potentially life-threatening condition characterised by markedly elevated creatine phosphokinase (CPK) values greater than 10 times the upper limit of normal. DEZZOLIP should be discontinued if CPK increases significantly or if myopathy is diagnosed.

The risk of myopathy during treatment with DEZZOLIP is increased with concomitant use of immunosuppressive medicines, including ciclosporin, fibric acid derivatives, nicotinic acid, azole antifungals or erythromycin, and cytochrome P450 inhibitors (See 4.5).

DEZZOLIP therapy should be withdrawn in any patient with an acute, serious condition suggestive of a myopathy or having a risk factor predisposing to the development of renal failure secondary to rhabdomyolysis, (e.g., severe acute infection, hypotension, major surgery, trauma, severe metabolic, endocrine and electrolyte disorders, and uncontrolled seizures).

DEZZOLIP should be used with caution in patients with renal impairment as the risk of myopathy is increased.

Before the treatment

DEZZOLIP should be prescribed with caution in patients with pre-disposing factors for rhabdomyolysis. A creatine kinase (CK) level should be measured before starting treatment in the following situations:

  • renal impairment
  • hypothyroidism
  • personal or familial history of hereditary muscular disorders
  • previous history of muscular toxicity with a statin or fibrate
  • previous history of liver disease and/or where substantial quantities of alcohol are consumed
  • in elderly (age >70 years), the necessity of such measurement should be considered, according to the presence of other predisposing factors for rhabdomyolysis.
  • situations where an increase in plasma levels may occur, such as interactions and special populations including genetic subpopulations.

In such situations, the risk of treatment should be considered in relation to possible benefit, and clinical monitoring is recommended.

If CK levels are significantly elevated (>5 times ULN) at baseline, treatment should not be started.

Creatine kinase measurement

Creatine kinase (CK) should not be measured following strenuous exercise or in the presence of any plausible alternative cause of CK increase as this makes value interpretation difficult. If CK levels are significantly elevated at baseline (> 5 times ULN), levels should be re-measured within 5 to 7 days later to confirm the results.

Whilst on treatment:

  • Patients must be asked to promptly report muscle pain, cramps, or weakness especially if accompanied by malaise or fever.
  • If such symptoms occur whilst a patient is receiving treatment with atorvastatin, their CK levels should be measured. If these levels are found to be significantly elevated (>5 times ULN), treatment should be stopped.
  • If muscular symptoms are severe and cause daily discomfort, even if the CK levels are elevated to ≤5 x ULN, treatment discontinuation should be considered.
  • If symptoms resolve and CK levels return to normal, then re-introduction of DEZZOLIP or introduction of an alternative statin may be considered at the lowest dose and with close monitoring.
  • DEZZOLIP must be discontinued if clinically significant elevation of CK levels (>10 x ULN) occur, or if rhabdomyolysis is diagnosed or suspected.

Protease inhibitors

Co-administration of DEZZOLIP and protease inhibitors increases plasma concentrations of DEZZOLIP.

Haemorrhagic stroke

In a post-hoc analysis of a clinical study, patients without coronary heart disease (CHD) who had a stroke or transient ischaemic attack (TIA) within the preceding 6 months who were initiated on atorvastatin 80 mg revealed a higher incidence of haemorrhagic stroke compared to placebo. Patients with haemorrhagic stroke on entry appeared to be at increased risk for recurrent haemorrhagic stroke.

Increase in glycosylated haemoglobin (HbAIB) and fasting serum glucose levels have been reported with statin use.

4.5. Interaction with other medicinal products and other forms of interaction

The most serious consequence of interactions with DEZZOLIP is the development of myopathy or rhabdomyolysis. Medicines that cause myopathy when given alone increase the risk of myopathy with DEZZOLIP; these medicines include fibric acid derivatives (fibrates or gemfibrozil), and nicotinic acid. The risk of myopathy is also increased by medicines that increase the plasma concentrations of DEZZOLIP, by inhibiting their metabolism or by inhibiting their uptake into the liver.

Inhibitors of cytochrome P450 3A4

DEZZOLIP is metabolised by the cytochrome P450 isoenzyme CYP3A4 and interactions may occur with medicines that inhibit this enzyme, including immunosuppressants (ciclosporin), itraconazole, ketoconazole, erythromycin, clarithromycin, telithromycin, HIV-protease inhibitors, nefazodone, danazol, amiodarone, and verapamil. There may also be a similar interaction with grapefruit juice. Such combinations should be used with caution, if at all, and dose reduction may be revised.

Rhabdomyolysis may be reported when atorvastatin is given with the non-nucleoside reverse transcriptase inhibitor delavirdine.

Rhabdomyolysis and hepatitis have also been reported in patients receiving atorvastatin with diltiazem.

Inducers of cytochrome P450 3A4

Concomitant administration of DEZZOLIP with inducers of cytochrome P450 isoenzyme CYP3A4 (e.g. efavirenz, rifampicin, St. John’s Wort) can lead to variable reductions in the plasma concentrations of DEZZOLIP. Due to the dual interaction mechanism of rifampicin, simultaneous co-administration of DEZZOLIP with rifampicin is recommended, as delayed administration of atorvastatin after administration of rifampicin has been associated with a significant reduction in DEZZOLIP plasma concentrations.

Antacids

Co-administration of an oral antacid suspension containing magnesium and aluminium hydroxides decreases plasma concentrations of DEZZOLIP approximately 35%, however, LDL-C reduction is not altered.

Colestipol

Plasma concentrations of DEZZOLIP decreased approximately 25% when colestipol and DEZZOLIP were co-administered. However, LDL-C reduction was greater when DEZZOLIP and colestipol were co-administered than when either medicine was given alone.

Digoxin

Co-administration of multiple doses of DEZZOLIP and digoxin increased steady-state plasma digoxin concentrations. Patients taking digoxin should be monitored appropriately.

Oral contraceptives

Co-administration of DEZZOLIP with an oral contraceptive produces increases in plasma concentrations of norethindrone and ethinyl oestradiol.

Warfarin

Prothrombin time should be determined before starting DEZZOLIP in patients taking warfarin or other oral anticoagulants and frequently enough during early therapy to ensure that no significant alteration of prothrombin time occurs. Once a stable prothrombin time has been documented, prothrombin times can be monitored at the intervals usually recommended for patients on warfarin or other oral anticoagulants. If the dose of DEZZOLIP is changed or discontinued, the same procedure should be repeated.

4.6. Fertility, pregnancy and lactation

DEZZOLIP is contraindicated in pregnancy, during breastfeeding and in women of child-bearing potential (See 4.3). Women of child-bearing potential should use appropriate contraceptive measures during treatment. An interval of one month should be allowed from stopping DEZZOLIP treatment to conception in the event of planning a pregnancy.

Treatment with DEZZOLIP should be suspended for the duration of pregnancy or until it has been determined that the woman is not pregnant.
