The article deals with the diagnosis of dizziness as one of the most common reasons for contacting the primary care system. The term “vertigo” refers to the illusory sensation of the rotational movement of objects around the patient or the patient himself. Traditionally, the clinic distinguishes “systemic” and “non-systemic” dizziness. However, the use of these two terms “systemic” (rotational) and “non-systemic” (presyncope, imbalance caused by a violation of the neural mechanisms for maintaining balance and balance of the body and postural phobic) dizziness can make it difficult to diagnose the etiological factor due to the ambiguity of the term “non-systemic”. The most severe and painful for the patient is rotational dizziness. Most often, dizziness is caused by pathological changes in the peripheral part of the vestibular system: vestibular neuronitis, benign paroxysmal positional vertigo, Meniere’s disease. Treatment of patients with dizziness involves etiopathogenetic and symptomatic therapy. Important, from a practical point of view, is the relief of rotational dizziness itself, regardless of its etiology. A number of studies have shown the possibility of using the combined drug cinnarizine 20 mg + dimenhydrinate 40 mg in the treatment of peripheral and central vertigo. The effectiveness of therapy for dizziness with the use of a combined drug is due to the fact that one component (cinnarizine) acts mainly on peripheral structures (labyrinth), and the second (dimenhydrinate) – on central (vestibular nuclei and related centers of the brain stem) structures, providing a good vestibulolytic effect . The drug has minimal undesirable effects, which makes it possible to use it in patients of different age groups. In the article, the authors consider the effectiveness of a fixed combination of cinnarizine 20 mg and dimenhydrinate 40 mg for the treatment and prevention of rotational verti go (vertigo) of various etiologies with the analysis of clinical cases.
