Brief summary
This is a single-center, prospective, randomized, double-blind (pharmacotherapy), placebo-controlled, and comprehensive rehabilitation phase II clinical trial to determine the usefulness of pregabalin in a new indication (post-COVID chronic fatigue syndrome). Patients will be randomized in a 1:1:1:1 ratio to pregabalin (75-300 mg daily in two divided doses), comprehensive rehabilitation with a placebo drug, comprehensive rehabilitation with pregabalin (75-300 mg in two divided doses), or placebo (two divided doses) for 6 months (177-187 days). There will be 4 outpatient visits to the research center and 12 telephone consultations. The procedures and assessments performed as part of the study are listed in the study schedule. It is planned to include 132 patients in the study, which, assuming a 10% level of non-completion of the program, will result in the examination of 120 patients (30 in each arm). Patients will be recruited during an outpatient medical consultation with a general practitioner or neurologist, psychiatrist, psychologist or other specialists, as well as with the use of information materials in the form of leaflets and advertisements on the Internet.
