During his twoyear pharmacotherapeutic therapy, he took SSRIs, SNRIs, TeCAs, SARIs, atypical antipsychotics with antidepressant effects, such as aripiprazole and cariprazine. Since the patient still did not have adequate therapeutic response and new drugs were available, the choice fell on Memantine after researching several databases and collecting the data listed at the beginning of the article. The initial dose was 5 mg daily and was gradually increased by 5 mg each week to a maximum of 20 mg. After 2 weeks at a stable dose, the patient reported feeling a little better.
