The lifestyle change that underlies the treatment of such a prevalent chronic disease as obesity is often insufficient to successfully clinically relevant reduce body weight, especially in the presence of comorbid conditions and diseases (type 2 diabetes, atherogenic dyslipidemia, arterial hypertension, ischemic heart disease, hyperuricemia and gout, obstructive sleep apnea syndrome, polycystic ovary syndrome and other menstrual irregularities etc.). The availability in our country until recently, only two drugs for the treatment of obesity is extremely limited choice in the case of existing contraindications to this or another drug or the appearance of any side effects. The registration in Russia in 2016 of a new drug for the treatment of obese patients, including morbid or complicated concomitant diseases and conditions, an analogue of human glucagon-like peptide-1 — liraglutide in a dose of 3.0 mg, has replenished the arsenal of obesity pharmacotherapy and substantially extended capabilities of management of obesity and overweight including patients with severe comorbidities.
