4.2       Posology and Method of Administration

 

Imigran Ftab is indicated for the acute intermittent treatment of migraine. Imigran Ftab should not be used prophylactically.

 

Imigran Ftab is recommended as monotherapy for the acute treatment of a migraine and should not be given concomitantly with ergotamine or derivatives of ergotamine (including methysergide) (see section 4.3).other acute migraine therapies. If a patient fails to respond to a single dose of Imigran Ftab there are no reasons, either on theoretical grounds or from limited clinical experience, to withhold products containing aspirin or non-steroidal anti-inflammatory drugs for further treatment of the attack.

 

It is advisable that Imigran Ftab be given as early as possible after the onset of a migraine headache. It is equally effective at whatever stage of the attack it is administered.

 

Adults only:

The recommended adult dose of oral Imigran Ftab is a single 50 mg tablet. Some patients may require 100 mg.

 

If a patient does not respond to the first dose of Imigran Ftab, a second dose should not be taken for the same attack. Imigran Ftab may be taken for subsequent attacks.

 

If the patient has responded to the first dose, but the symptoms recur, a second dose may be given in the next 24 hours, provided that not more than 300 mg is taken in any 24 hour period. An interval of two hours should generally be allowed to elapse between doses. An interval of two hours should generally be allowed to elapse between doses.

 

The tablets should be swallowed whole with water. Patients with swallowing difficulties may choose to disperse a tablet in a small amount of water before administration. Imigran Ftab dispersed in water have a bitter taste.

 

Children and Adolescents (under 18 years of age)

Imigran Ftab fast disintegrating tablets are not recommended for use in children and adolescents due to insufficient data on safety and efficacy.have not been studied in adolescents or children (see Clinical Studies).

 

Elderly (over 65):

Experience of the use of Imigran Ftab in patients aged over 65 years is limited. The pharmacokinetics do not differ significantly from a younger population but, until further clinical data are available, the use of Imigran Ftab in patients aged over 65 years is not recommended.

 

Patients with Hepatic Impairment:

Impairment of hepatic function gives rise to an 80% increase in plasma sumatriptan levels after an oral dose of 100mg. The drug should therefore be used with extreme caution and at reduced dosage in these patients.

 

Patients with Renal Impairment:

There is no information on the effect of renal impairment.

 

4.3       Contra-indications

 

Hypersensitivity to sumatriptan or to any of the excipientsany component of the preparation.

 

Sumatriptan should not be given to patients who have had a myocardial infarction or have ischaemic heart disease, coronary vasospasm (Prinzmetal’s angina), peripheral vascular disease or patients who have symptoms or signs consistent with ischaemic heart disease.

 

Sumatriptan should not be administered to patients with a history of cerebrovascular accident (CVA) or transient ischaemic attack (TIA).

 

Sumatriptan should not be administered to patients with severe hepatic impairment.

 

The use of sumatriptan in patients with moderate and severe hypertension and mild uncontrolled hypertension is contra-indicated.

 

The concomitant administration of ergotamine, or derivatives of ergotamine (including methysergide) or any triptan/5-hydroxytryptamine1 (5-HT1) receptor agonist is contra-indicated (see section 4.5Interaction with other medicinal products and other forms of Interaction).

 

Concurrent administration of monoamine oxidase inhibitors (MAOIs) and sumatriptan or use within two weeks of discontinuation of MAOI therapy is contra-indicated.

 

Imigran must not be used within 2 weeks of discontinuation of therapy with monoamine oxidase inhibitors.

Imigran Ftab should not be given to diabetic patients.

 

4.4       Special Warnings and Special Precautions for Use

 

Imigran Ftab should only be used where there is a clear diagnosis of migraine.

 

Sumatriptan is not indicated for use in the management of hemiplegic, basilar or ophthalmoplegic migraine.

 

As with other acute migraine therapies, before treating headaches in patients not previously diagnosed as migraineurs, and in migraineurs who present with atypical symptoms, care should be taken to exclude other potentially serious neurological conditions.

 

There have been a number of reports of CVA (stroke, paresis), where a temporal association with sumatriptan intake was seen. It should be noted that migraineurs may be at increased risk of certain cerebrovascular events (e.g. CVA, TIA).

 

Following administration, sumatriptan can be associated with transient symptoms including chest pain and tightness, which may be intense and involve the throat (see section 4.8). Where such symptoms are thought to indicate ischaemic heart disease, no further doses of sumatriptan should be given and an appropriate evaluation should be carried out.

 

Sumatriptan should not be given to patients with risk factors for ischaemic heart disease, including those patients who are heavy smokers or users of nicotine substitution therapies, without prior cardiovascular evaluation (see section 4.3).Special consideration should be given to postmenopausal women and males over 40 with these risk factors. These evaluations however, may not identify every patient who has cardiac disease and, in very rare cases, serious cardiac events have occurred in patients without underlying cardiovascular disease (see section 4.8).

Imigran Ftab should not be used in patients with underlying cardiac disorders and in patients who, although asymptomatic, have significant risk factors predisposing to coronary artery disease. Therefore a careful history to exclude pre-existing cardiac disease should be taken before sumatriptan is prescribed. Evaluations may not identify every patient who has cardiac diseases and, in very rare cases, serious cardiac events have occurred in patients without underlying cardiovascular disease and in the absence of known risk factors.

 

Patients in whom undiagnosed coronary artery disease is a possibility on the basis of age or the presence of other risk factors, such as family history of coronary artery disease, tobacco smoking, diabetes, hypercholesterolaemia, should receive the product only with great caution and if the benefit of treatment is judged to outweigh the possible risk. Use of sumatriptan should be carefully considered in patients who may be at risk of thrombotic episodes. There have been rare reports of patients on hormone replacement therapy who have had cardiac ischaemic events.

 

There have been rare post-marketing reports describing patients with serotonin syndrome (including altered mental status, autonomic instability and neuromuscular abnormalities) following the use of a selective serotonin reuptake inhibitor (SSRI) and sumatriptan. Serotonin syndrome has been reported following concomitant treatment with triptans and serotonin noradrenaline reuptake inhibitors (SNRIs).

 

If concomitant treatment with sumatriptan and an SSRI/SNRI is clinically warranted, appropriate observation of the patient is advised (see section 4.5)

 

Following administration, sumatriptan can be associated with transient symptoms including chest pain and tightness which may be intense and involve the throat and arms. These symptoms may mimic angina pectoris but, in patients in whom cardiac investigations have been performed, they have only rarely been found to have been the result of coronary vasospasm. Although rare, the vasospasm may result in arrhythmia including ventricular fibrillation/ischaemia or myocardial infarction. If the patient experiences symptoms which are severe or persistent or are consistent with angina, further doses should not be taken until appropriate investigations have been carried out to check for the possibility of ischaemic changes.

 

There have been a number of fatalities from ventricular fibrillation and myocardial infarction.

 

Sumatriptan should be administered with caution to patients with controlled hypertension as transient increases in blood pressure and peripheral vascular resistance have been observed in a small proportion of patients.

 

Sumatriptan should be administered with caution to patients with conditions, which may affect significantly the absorption, metabolism or excretion of the drug, e.g. impaired hepatic or renal function.

 

Patients with known hypersensitivity to sulphonamides may exhibit an allergic reaction following administration of sumatriptan. Reactions may range from cutaneous hypersensitivity to anaphylaxis. Evidence of cross sensitivity is, limited, however, caution should be exercised before using sumatriptan in these patients.

 

Undesirable effects may be more common during concomitant use of triptans and herbal preparations containing St. John’s wort (Hypericum perforatum).

 

Sumatriptan should be used with caution in patients with a history of seizures or other risk factors which lower the seizure threshold, as seizures have been reported in association with sumatriptan (see section 4.8).

 

Prolonged use of any type of painkiller for headaches can make them worse. If this situation is experienced or suspected, medical advice should be obtained and treatment should be discontinued. The diagnosis of medication overuse headache (MOH) should be suspected in patients who have frequent or daily headaches despite (or because of) the regular use of headache medications.

 

The recommended dose of Imigran Ftab should not be exceeded.

 

There have been rare post-marketing reports describing patients with serotonin syndrome (including altered mental status, autonomic instability and neuromuscular abnormalities) following the use of a selective serotonin reuptake inhibitor (SSRI) and sumatriptan. Serotonin syndrome has been reported following concomitant treatment with triptans and serotonin noradrenaline reuptake inhibitors (SNRIs).

 

If concomitant treatment with sumatriptan and an SSRI/SNRI is clinically warranted, appropriate observation of the patient is advised (see Interactions).

 

The concomitant administration of any triptan/5-HT1 agonist with sumatriptan is not recommended.

 

Overuse of acute migraine treatments has been associated with the exacerbation of headache (Medication Overuse Headache, MOH) in susceptible patients. Withdrawal of the treatment may be necessary.

 

4.5       Interaction with other medicaments and other forms of interaction

 

There is no evidence of interactionsStudies in healthy subjects show that Imigran does not interact with propranolol, flunarizine, pizotifen or alcohol.

 

There are limited data on an interaction with preparations containing ergotamine or another triptan/5-HT1 receptor agonistcontaining preparations. The increased risk of coronary vasospasm is a theoretical possibility and concomitant administration is contra-indicated (see section 4.3).

 

The period of time that should elapse between the use of sumatriptan and ergotamine containing preparations or another triptan/5-HT1 receptor agonist is not known. This will also depend on the doses and type of ergotamine containing products used. The effects may be additive. It is advised to wait at least 24 hours following the use of ergotamine containing preparations or another triptan/5-HT1 receptor agonist before administering sumatriptan. Conversely, it is advised to wait at least six 6 hours following use of sumatriptan before administering an ergotamine containing product and at least 24 hours before administering another triptan/5-HT1 receptor agonist.(see Contra-indications).

 

An interaction may occur between sumatriptan and MAOIs and concomitant administration is contraindicatedThere is a risk of CNS toxicity when both MAOI’s and SSRI’s are given with Imigran; hence concomitantant use is contraindicated (see section 4.3)

 

There have been rare post-marketing reports describing patients with serotonin syndrome (including altered mental status, autonomic instability and neuromuscular abnormalities) following the use of SSRIs and sumatriptan. Serotonin syndrome has also been reported following concomitant treatment with triptans and SNRIs (see section 4.4Warnings and Precautions).

 

4.6       Pregnancy and Lactation

 

Pregnancy:

Post-marketing data on the use of sumatriptan during the first trimester of pregnancy in over 1,000 women are available. Although these data contain insufficient information to draw definitive conclusions, they do not point to an increased risk of congenital defects. Experience with the use of sumatriptan in the second and third trimester is limited.

 

Evaluation of experimental animal studies does not indicate direct teratogenic effects or harmful effects on peri- and postnatal development. However, embryo-foetal viability might be affected in the rabbit (see section 5.3). Administration of sumatriptan should only be considered if the expected benefit to the mother is greater than any possible risk to the foetus.Caution should be exercised by considering the expected benefit to the mother against possible risk to the foetus

 

Post-marketing data from multiple prospective pregnancy registries have documented the pregnancy outcomes in over 1,000 women exposed to sumatriptan. Although there is insufficient information to draw definitive conclusions, the findings have not detected an increase in the frequency of birth defects nor a consistent pattern of birth defects, amongst women exposed to sumatriptan compared with general population.

 

Lactation:

It has been demonstrated that following subcutaneous administration sumatriptan is excreted into breast milk. Infant exposure can be minimised by avoiding breast-feeding for 12 hours after treatment, during which time any breast milk expressed should be discarded.

 

4.7       Effects on the ability to drive and operate machinery

 

No studies on the effects on the ability to drive and use machines have been performed. Drowsiness may occur as a result of migraine or its treatment with Imigran Ftab. This may influence the ability to drive and to operate machinery.Caution is recommended in patients performing skilled tasks, e.g. driving or operating machinery.

 

4.8       Undesirable effects

 

Adverse events are listed below by system organ class and frequency. Frequencies are defined as: very common (>1/10), common (>1/100, <1/10), uncommon (>1/1000, <1/100), rare (>1/10,000, <1/1000) and very rare (<1/10,000) , not known (cannot be estimated from the available data).  Some of the symptoms reported as undesirable effects may be associated symptoms of migraine.including isolated reports.
