Ditreineo should not be given to patients with known hypersensitivity to cinnarizine.
As with other antihistamines, Ditreineoe may cause epigastric discomfort; taking it after meals may diminish gastric irritation. Ditreineoe should only be given to patients with Parkinson's disease if the advantages outweigh the possible risk of aggravating this disease.
Use of Ditreineoe should be avoided in porphyria.
There have been no specific studies in hepatic or renal dysfunction. Ditreineoe should be used with care in patients with hepatic or renal insufficiency.
Ditreineoe Tablets contain lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.
As with other antihistamines, Ditreineo may cause epigastric discomfort; taking it after meals may diminish the gastric irritation.
In patients with Parkinson's Disease, Ditreineo should only be given if the advantages outweigh the possible risk of aggravating this disease.
Because of its antihistamine effect, Ditreineo may prevent an otherwise positive reaction to dermal reactivity indicators if used within 4 days prior to testing.
Use of cinnarizine should be avoided in porphyria.
There have been no specific studies in hepatic or renal dysfunction. Ditreineo should be used with care in patients with hepatic or renal insufficiency.
Patients with rare hereditary problems of fructose or galactose intolerance, Lapp lactase deficiency, glucose-galactose malabsorption or sucrase-isomaltase insufficiency, should not take this medicine because it contains lactose and sucrose.
Ditreineoe may cause drowsiness, especially at the start of treatment; patients affected in this way should not drive or operate machinery.

The safety of Ditreineoe was evaluated in 372 Ditreineoe-treated subjects who participated in 7 placebo-controlled trials for the indications peripheral circulatory disorders, cerebral circulatory disorders, vertigo and seasickness; and in 668 Ditreineoe treated subjects who participated in six comparator and thirteen open label clinical trials for the indications peripheral circulatory disorders, cerebral circulatory disorders and vertigo. Based on pooled safety data from these clinical trials, the most commonly reported (>2% incidence) adverse drug reactions (ADRs) were: somnolence (8.3) and weight increased (2.1).
Including the above mentioned ADRs, the following ADRs have been observed from clinical trials and post-marketing experiences reported with the use of Ditreineoe. Frequencies displayed use the following convention:

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.

Symptoms
The signs and symptoms are mainly due to the anticholinergic (atropine-like) activity of Ditreineoe.
Acute Ditreineoe overdoses have been reported with doses ranging from 90 to 2,250 mg. Vomiting, alterations in consciousness ranging from somnolence to stupor and coma, extrapyramidal symptoms and hypotonia are the most commonly reported signs and symptoms associated with a Ditreineoe overdose. 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 Ditreineoe.
Treatment
There is no specific antidote to Ditreineoe and in the event of overdosage, treatment is symptomatic and supportive care. The administration of activated charcoal should only be considered in patients presenting within one hour of taking a potentially toxic overdose (i.e. more than 15 mg/kg).
Symptoms

Treatment
There is no specific antidote. For any overdose, the treatment is symptomatic and supportive care.
It is advisable to contact a poison control center to obtain the latest recommendations for the management of an overdose.
Pharmacotherapeutic group: Antivertigo preparations, ATC code: N07CA02.
Mechanism of action
Ditreineoe is a piperazine derivative with the actions and uses of the antihistamines.
Ditreineoe has been shown to be a non-competitive antagonist of the smooth muscle contractions caused by various vasoactive agents including histamine. It acts on smooth muscle by selectively inhibiting the transport of calcium ions across cell membranes into depolarised cells, therefore reducing the availability of free Ca+ ions for the induction and maintenance of contraction.
Pharmacodynamic effects
Vestibular eye reflexes induced by caloric stimulation of the labyrinth in guinea pigs are markedly depressed by Ditreineoe.
Ditreineoe has been shown to inhibit nystagmus.
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 depolarised 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.
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 Ditreineoe is 91%
Biotransformation
In animals, Ditreineoe is extensively metabolised, N-dealkylation being the major pathway.
Ditreineoe undergoes extensive metabolism mainly via CYP2D6 but there is considerable interindividual variation in the extent of metabolism.
Elimination
Approximately two thirds of the metabolites are excreted with the faeces, the rest in the urine (unchanged as metabolites and glucuronide conjugates), mainly during the first five days after a single dose.
The reported elimination half-life for Ditreineoe ranges from 4 to 24 hours.

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. Ditreineoe 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 foetal 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.
