6. Further information



The name of your medicine is Pizotifen 0.5mg or 1.5mg Tablets. The active ingredient is pizotifen

hydrogen malate.

Pizotifen belongs to a group of medicines called anti-migraines. Pizotifen is used to help block the

actions of certain chemicals in the blood such as serotonin, histamine and tryptamine. These

chemicals act on the blood vessels in the brain and are involved in causing types of headache, such

as migraine.

If Pizotifen 0.5mg or 1.5mg Tablets are taken regularly, they can help reduce the number and severity

of headaches including the pain of cluster headaches and both common and classical migraine.

Pizotifen can also prevent some migraine attacks starting and helps make other attacks less severe.

Pizotifen does not help to relieve a migraine attack once it has started


Do not take this medicine if:

you have ever had an allergic reaction to any of the ingredients of Pizotifen Tablets or any other

medicines that you may have taken to treat headaches

you are pregnant, or if you are breast feeding an infant

Pizotifen must not be given to children under the age of 2 years

Take special care with this medicine and tell your doctor or pharmacist if:

you suffer from kidney problems

you are pregnant, trying to become pregnant or breast-feeding

you have difficulty passing water

you suffer with glaucoma (raised pressure in the eyes)

you suffer, or have suffered, from epilepsy

5. Pharmacological properties

5.1 Pharmacodynamic properties

Pharmacotherapeutic group: antimigraine drug, ATC code: N02C X01

Studies in experimental animals have indicated that pizotifen has strong anti-serotonin and anti-

tryptaminic properties, marked antihistaminic effects and some antagonistic activity against kinins. It also

possesses weak anti-cholinergic effects and sedative properties.

Pizotifen also possesses appetite-stimulating properties.

The prophylactic effect of pizotifen in migraine is associated with its ability to modify the humoral

mechanisms of headache.

It inhibits the permeability-increasing effect of serotonin and histamine on the affected cranial vessels,

thereby checking the transudation of plasmakinin so that the pain threshold of the receptors is maintained

at 'normal' levels. In the sequence of events leading to migraine attack, depletion of plasma serotonin

contributes to loss of tone in the extracranial vessels. Pizotifen inhibits serotonin re- uptake by the

platelets, thus maintaining plasma serotonin and preventing the loss of tone and passive distension of the

extracranial arteries.

5.2 Pharmacokinetic properties


The absorption of pizotifen in man is fast (absorption half-life 0.5 to 0.8 hours) and nearly complete. The

absolute bioavailablility is 78%. Maximum blood levels are reached 5 hours after a single 2 mg oral

administration of pizotifen (parent compound and N-glucuronide-conjugate measured together).


Pizotifen is extensively metabolised. Glucuronidation is the main route of biotransformation and the main

metabolite is the N-glucuronide-conjugate, accounting for at least 50% of the plasma and 60-70% of

urinary excreted radioactivity.


Protein binding of pizotifen in human plasma in vitro amounts to 91%. The distribution volume in man is

833 L and 70 L for pizotifen and its N-glucuronide, respectively.


About one-third of an orally applied dose is excreted via the biliary route into the faeces, a significant

proportion, corresponding to about 18% of the applied dose, representing parent drug, likely produced in

the intestine after biliary excretion of the N-glucuronide-conjugate. Less than 1% of the administered

dose of pizotifen is excreted unchanged in the urine, whereas up to 55% is excreted as metabolites.

Pizotifen is eliminated with a half life of approximately 23 hours (total radioactivity).

Unchanged pizotifen and the N-glucuronide have, as estimated from the excretion in the urine, a

comparable elimination half-life.

Special patient groups

In patients with kidney insufficiency, dosage adjustment may be necessary.

5.3 Preclinical safety data

There are no preclinical data of relevance to the prescriber which are additional to those in other sections
