Study Details
Study Description
Brief Summary
The goal of this clinical trial is to assess the efficacy and safety of a combination of aminobutyric acid, glutamic acid, calcium, thiamine, pyridoxine and cyanocobalamin as adjuvant therapy for vertigo comparatively to ginger under a double-blind randomized study design.

Detailed Description
Motion sickness is a chronic condition characterized by vestibular changes in response to stimuli caused either by movement or movement perception triggered by car, train, ship or aircraft transportation, amusement park rides, virtual reality and simulators, walking, exercising, as well as under the absence of gravity in space.The studied combination drug is composed by GABA (gamma-aminobutyric acid), the main inhibitory neurotransmitter of the central nervous system. The former lowers anxiety symptoms. Its precursor, glutamic acid, is the amino acid found in greater concentration under free form in the CNS; it is closely related to brain metabolism and, in contrast to GABA, it is the main excitatory neurotransmitter; glutamic acid also has anxyolytic therapeutic properties. Thiamine or vitamin B1 is a cofactor in the synthesis of acetylcholine, which plays a central role in the initiation and propagation of neural impulse in the CNS as well as it does in the skeletal and myocardial muscles. Pyridoxine or vitamin B6 plays a role in the synthesis of neurotransmitters such as dopamine as well as in the metabolism of tryptophan, resulting in an increase in serotonin so providing well-being and anxiety relief. Pyridoxine is essential for the proper functioning of the CNS (including at nausea and vomiting center). Cyancobalamin or Vitamin B12 plays a role in the growth and repair of nerve fibers. Importantly it also improves blood flow in the brain, with secondary vertigo improvement. The combined use of these substances provides relief of vertigo due to motion sickness. Zingiber officinale is a species of the Zingiberacaea family, widely used in traditional and herbal medicine for the treatment of various clinical conditions such as vertigo.

Outcome Measures
Primary Outcome Measures
- motion sickness assessment questionnaire [1 year]
The MSAQ consists of 16 questions, answered on a scale from one to nine points, which assesses the gastrointestinal, central and peripheral nervous system and soporous symptoms related to motion sickness.
