Cinnarizine provides quick relief of various symptoms of cerebral and peripheral circulation disorders. Cinnarizine protects attacks of vascular headache such as migraine. Cinnarizine normalizes cerebral circulation time and improves cerebral irrigation in patients suffering from the disorders of cerebral circulation. Cinnarizine normalizes arterial pulsations in patients suffering from vasospastic disorders. Cinnarizine significantly increases the rate of inflow or pulsation and the blood flow in the most affected limb as well as the walking distance of patients suffering from intermittent claudication.

Cinnarizine acts as an antihistamine, labyrinthine sedative and a peripheral antivasoconstrictor. Inarzin is a selective calcium antagonist, inhibiting the influx of Ca2+ intracellularly. It prevents the Ca2+ dependent contraction of arterial smooth muscle by inhibiting Ca2+ influx through smooth muscle calcium channels and thereby, improves vestibular symptoms and prevents peripheral arterial disease.

Cinnarizine is an antihistamine and a calcium channel blocker. Histamines mediate a number of activities such as contraction of smooth muscle of the airways and gastrointestinal tract, vasodilatation, cardiac stimulation, secretion of gastric acid, promotion of interleukin release and chemotaxis of eosinophils and mast cells. Competitive antagonists at histamine H1 receptors may be divided into first (sedating) and second (non-sedating) generation agents. Some, such as Cinnarizine also block muscarinic acetylcholine receptors and are used as anti-emetic agents. Cinnarizine through its calcium channel blocking ability also inhibits stimulation of the vestibular system.

Domperidone is dopamine receptor (D2) antagonist which selectively inhibits dopamine at the D2 receptor. It acts principally at receptors in the chemoreceptor trigger zone (CTZ) and also at receptors in the stomach.

Domperidone is a specific blocker of dopamine receptors. It speeds gastrointestinal peristalsis, causes prolactin release, and is used as antiemetic and tool in the study of dopaminergic mechanisms.

Uses

It is mainly used for the symptomatic treatment of nausea and vertigo due to Meniere's disease and other labyrinthine disturbances and for the prevention and treatment of motion sickness. It is also used in the management of various vascular disorders.

Cerebral circulatory disorders:

  • Prophylaxis and maintenance therapy for symptoms of cerebral vascular spasms and arteriosclerosis such as dizziness, ear buzzing (tinnitus), vascular headache, unsociability and irritability, fatigue, sleep rhythm disorders such as premature awakening, involutional depressions, loss of memory and lack of concentration, incontinence and other disorders due to aging.
  • Sequel of cerebral and cranial trauma.
  • Post-apoplectic disorders.
  • Migraine.

Peripheral circulatory disorders: Prophylaxis and maintenance therapy for symptoms of vascular spasms and arteriosclerosis (obliterating arteritis, thromboangitis obliterans, Raynaud's disease, diabetes, acrocyanosis, perrio, etc.) such as: intermittent claudication, trophic disturbances, pregangrene, trophic and varicose ulcers, paraesthesia, nocturnal cramps, cold extremities.

Disorders of balance:

  • Prophylaxis and maintenance therapy for symptoms of labyrinthine arteriosclerosis, vestibular irritability, Meniere's syndrome, such as vertigo, dizziness, giddiness, syncopal attacks, tinnitus, nystagmus, nausea and vomiting.
  • Prophylaxis of motion sickness.

Stimulation of gut motility in-

  • Non-ulcer dyspepsia
  • Oesophageal reflux, reflux oesophagitis and gastritis
  • Diabetic gastroparesis
  • Functional dyspepsia
  • Speeding barium transit in follow through radiological studies

Prevention and symptomatic relief of acute nausea and vomiting from any cause including cytotoxic therapy, radiotherapy and antiparkinsonism therapy.

In the prophylactic treatment of migraine.

Domley C is also used to associated treatment for these conditions: Balance Disorders, Dizziness, Motion Sickness, Nausea, Peripheral Artery Disease (PAD), Raynaud's Phenomenon, Inadequate cerebral circulation, Peripheral vasculopathyDiabetic Gastroparesis, Dyspepsia, Erosive Esophagitis, Gastrointestinal Symptoms, Non-erosive Reflux Esophagitis Disease (NERD), Upper gastrointestinal motility disorders

How Domley C works

Cinnarizine inhibits contractions of vascular smooth muscle cells by blocking L-type and T-type voltage gated calcium channels. Cinnarizine has also been implicated in binding to dopamine D2 receptors, histamine H1 receptors, and muscarinic acetylcholine receptors.

Domperidone acts as a gastrointestinal emptying (delayed) adjunct and peristaltic stimulant. The gastroprokinetic properties of domperidone are related to its peripheral dopamine receptor blocking properties. Domperidone facilitates gastric emptying and decreases small bowel transit time by increasing esophageal and gastric peristalsis and by lowering esophageal sphincter pressure. Antiemetic: The antiemetic properties of domperidone are related to its dopamine receptor blocking activity at both the chemoreceptor trigger zone and at the gastric level. It has strong affinities for the D2 and D3 dopamine receptors, which are found in the chemoreceptor trigger zone, located just outside the blood brain barrier, which - among others - regulates nausea and vomiting

Dosage

Domley C dosage

Peripheral vascular disease:

  • Adult: 75 mg bid or tid.

Cerebrovascular disorders:

  • Adult: 75 mg once daily.

Motion sickness:

  • Adult: 30 mg 2 hr before travel then 15 mg 8 hrly during the journey if necessary.
  • Child: 5-12 yr 15 mg 2 hr before travel then 7.5 mg 8 hrly during the journey as necessary.

Vertigo and vestibular disorders:

  • Adult: 30 mg tid or 75 mg 1-2 times daily.
  • Child: 5-12 yr 15 mg tid.

Adults: 10 - 20 mg every 4 - 8 hours daily

Children: 0.2 - 0.4 mg/kg every 4 - 8 hours daily.

Domperidone tablet and suspension should be taken 15 - 30 minutes before a meal. For acute nausea and vomiting, maximum period of treatment is 12 weeks.

Side Effects

Side effects such as somnolence and gastrointestinal disturbances are extremely rare. They are transient and may be readily prevented by achieving the optimal dosage gradually. Combination therapy with other drugs is possible. Whenever indicated, caution should be taken in hypotension (high doses). Rarely, extrapyramidal symptoms in elderly on prolonged therapy.

Domperidone may produce hyperprolactinemia which may cause galactorrhea & breast enlargement, soreness and reduced libido. It may rarely cause dry mouth, thirst, headache, nervousness, drowsiness, diarrhea, skin rash and itching.

Toxicity

Side effects include galactorrhea, gynecomastia, or menstrual irregularities.

Precaution

Patient with hypotension (high dose), Parkinson's disease, porphyria. Renal and hepatic impairment. Childn. Pregnancy and lactation.

Domperidone should be used with absolute caution in case of children because there may be an increased risk of extra-pyramidal reactions in young children because of an incompletely developed blood brain barrier.

Interaction

Concurrent use of alcohol, CNS depressants or tricyclic antidepressants may potentiate the sedative effects of either these drugs or of Cinnarizine. Therefore, it is advisable to avoid these drugs while taking Cinnarizine.

Domperidone may reduce the hypoprolactinaemic effect of bromocriptine. Anti-muscarinics and opioid analgesics may antagonize the action of Domperidone on gastrointestinal function.

Half Life

7 hours

Pregnancy & Breastfeeding use

Pregnancy Category C. The safety of Cinnarizine in human pregnancy has not been established. Therefore, it is not advisable to administer Cinnarizine in pregnancy.

Lactation: It is not known if Cinnarizine is excreted in human breast milk. Use of Cinnarizine during breast feeding is not advised.

Use in pregnancy: The safety of this drug has not been established for pregnant women. So it is not recommended during pregnancy.

Use in lactation: Domperidone may precipitate galactorrhea and improve postnatal lactation, which is secreted in breast milk but in very small quantities insufficient to be considered harmful.
