- 4.1 Therapeutic indications
Stugeron is effective in the control of motion sickness.4.2 Posology and method of administration
Posology
Stugeron should preferably be taken after meals.
\*Adults, elderly and children over 12 years:\*
2 tablets 2 hours before you travel and 1 tablet every 8 hours during your journey.
\*Children 5 to 12 years:\*
One half the adult dose.
Method of administration: Oral4.3 Contraindications
Stugeron should not be given to patients with known hypersensitivity to cinnarizine or to any of the excipients listed in section 6.14.4 Special warnings and precautions for use
As with other antihistamines, Stugeron may cause epigastric discomfort; taking it after meals may diminish gastric irritation.
In patients with Parkinson's disease, Stugeron should only be given if the advantages outweigh the possible risk of aggravating this disease.
Use of cinnarizine should be avoided in porphyria.
There have been no specific studies in hepatic or renal dysfunction. Stugeron should be used with care in patients with hepatic or renal insufficiency.
Patients with rare hereditary problems of fructose or galactose intolerance, the Lapp lactase deficiency, glucose-galactose malabsorption or sucrase- isomaltase insufficiency, should not take this medicine because it contains lactose and sucrose.
Stugeron may cause somnolence, especially at the start of treatment. Therefore caution should be taken when alcohol, central nervous system (CNS) depressants or tricyclic antidepressants are used concomitantly. Please also refer to section 4.5 Interactions with Other Medicinal Products and Other Forms of Interaction.
\*\*Diagnostic Interference\*\*
Because of its antihistamine effect, Stugeron may prevent an otherwise positive reaction to dermal reactivity indicators if used within 4 days prior to testing.4.5 Interaction with other medicinal products and other forms of interaction
Concurrent use of alcohol, CNS depressants or tricyclic antidepressants may potentiate the sedative effects of either of these drugs or of Stugeron.
\*\*Diagnostic interference\*\*
Because of its antihistamine effect, Stugeron may prevent otherwise positive reactions to dermal reactivity indicators if used up to 4 days prior to skin testing. Also refer to section 4.4 Special Warnings and Precautions for Use.4.6 Fertility, pregnancy and lactation
\*\*Pregnancy\*\*
The safety of Stugeron in human pregnancy has not been established although studies in animals have not demonstrated teratogenic effects. As with other drugs it is not advisable to administer Stugeron in pregnancy.
\*\*Lactation\*\*
There are no data on the excretion of Stugeron in human breast milk. Use of Stugeron is not recommended in nursing mothers.4.7 Effects on ability to drive and use machines
Stugeron may cause drowsiness, especially at the start of treatment; patients affected in this way should not drive or operate machinery.4.8 Undesirable effects
The safety of Stugeron (30-225mg/day) was evaluated in 601 subjects (of which 303 were treated with Stugeron, 298 were given placebo) who participated in 6 placebo-controlled, double-blind clinical trials; 2 in the treatment of peripheral circulatory disorders, 1 in the treatment of cerebral circulatory disorders, 1 in the treatment of vertigo, 1 in the prevention of motion sickness, and 1 in the treatment of both vertigo and cerebral circulatory disorders.
Six comparator trials and 13 open-label clinical trials were selected to determine the incidence of adverse reactions. In 19 studies, 937 subjects were treated with doses ranging from 25 to 450 mg/day Stugeron, in the treatment of peripheral circulatory disorders, cerebral circulatory disorders and vertigo.
Based on pooled safety data from these clinical trials, the most commonly reported (>1% incidence) Adverse Drug Reactions (ADRs) were: Somnolence (9.9%) and Weight Increased (1.5%).
Including the above-mentioned ADR, the following ADRs have been observed from clinical trials and post-marketing experiences reported with the use of Stugeron 15mg Tablets. Frequencies displayed use the following convention:
Very common (≥ 1/10); common (≥ 1/100 to < 1/10); uncommon (≥ 1/1,000 to < 1/100); rare (≥ 1/10,000 to <1/1,000); very rare (<1/10,000), not known (cannot be estimated from the available data).

\*\*Reporting of suspected adverse reactions\*\*
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard or search for MHRA Yellow Card in the Google Play or Apple App Store.4.9 Overdose
Symptoms
The signs and symptoms are mainly due to the anticholinergic (atropine-like) activity of cinnarizine. Acute cinnarizine overdoses have been reported with doses ranging from 90 to 2,250mg. The most commonly reported signs and symptoms associated with overdose of cinnarizine include: alterations in consciousness ranging from somnolence to stupor and coma, vomiting, extrapyramidal symptoms and hypotonia.
In a small number of young children, seizures developed. Clinical consequences were not severe in most cases, but deaths have been reported after single and polydrug overdoses involving cinnarizine.
Management
There is no specific antidote. For any overdose, the treatment is symptomatic and supportive care. It is advisable to contact a poison control centre to obtain the latest recommendation for the management of an overdose.
- Instruction Pharmacology
- 5.1 Pharmacodynamic properties
Pharmacotherapeutic group: Antivertigo preparations, ATC code: N07CA02
Cinnarizine has been shown to be a non competitive antagonist of the smooth muscle contractions caused by various vasoactive agents including histamine.
Cinnarizine also acts on vascular smooth muscle by selectively inhibiting the calcium influx into depolarized cells, thereby reducing the availability of free Ca2+ ions for the induction and maintenance of contraction.
Vestibular eye reflexes induced by caloric stimulation of the labyrinth in guinea pigs are markedly depressed by cinnarizine.
Cinnarizine has been shown to inhibit nystagmus.5.2 Pharmacokinetic properties
In animals, cinnarizine is extensively metabolised, N-dealkylation being the major pathway. Approximately two thirds of the metabolites are excreted with the faeces, the rest in the urine, mainly during the first five days after a single dose.
\*Absorption\*
In man, after oral administration, absorption is relatively slow, peak serum concentrations occurring after 2.5 to 4 hours.
\*Distribution\*
The plasma protein binding of cinnarizine is 91%.
\*Biotransformation\*
Cinnarizine is extensively metabolised mainly via CYP2D6, but there is considerable interindividual variation in the extent of metabolism.
\*Elimination\*
The reported elimination half-life for cinnarizine ranges from 4 to 24 hours.
The elimination of metabolites occurs as follows: one third in the urine (unchanged as metabolites and glucuronide conjugates) and two-thirds in the faeces.5.3 Preclinical safety data
Nonclinical safety studies showed that effects were observed only after chronic exposures from approximately 7 to 35 times the recommended maximum daily human dose of 90 mg/day calculated on a body surface area basis. Cinnarizine blocked the cardiac hERG channel in vitro, however in isolated cardiac tissue and following intravenous application in guinea-pigs, no QTc prolongation or proarrhythmic effects were observed at substantially higher exposures than those expected clinically.
In reproductive studies in the rat, rabbit, and dog, there was no evidence of adverse effects on fertility and no teratogenicity. At high doses associated with maternal toxicity in the rat there was a decreased litter size, an increase in resorptions and a decrease in fetal birth weight.
In vitro mutagenicity studies indicated that the parent compound is not mutagenic however, after reacting with nitrite and forming the nitrosation product, a weak mutagenic activity was observed. Carcinogenicity studies have not been conducted however, no pre-neoplastic changes were evident during chronic 18-month oral administration in rats up to approximately 35 times the maximum human dose level.
