To determine the relationship between alterations in the activity of the enzymes participating in antioxidative defense system and neurological soft signs (NSS) in schizophrenic patients with the first episode psychosis (S FE , n = 19), patients in relapse (S R , n = 46), and healthy controls (HC, n = 20). NSS intensity and enzymatic plasma activities of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) were compared between S FE , S R and HC subjects and a follow-up correlation analyses between the enzyme activities and NSS intensity was performed. NSS intensity was increased four times in schizophrenic patients compared with healthy controls. Activities of SOD and CAT were 40% decreased in S FE and these reductions were ameliorated by antipsychotic treatment. GPX activity was 20% decreased in both patient groups compared with controls. A negative correlation between NSS intensity and GPX activity was specifically found in the S FE patients. The data in this report argue that a reduction of GPX activity might be one of the causes for the emergence of NSS at the onset of schizophrenia, and provide the evidence that antipsychotic therapy can attenuate activity reductions of SOD and CAT, but not the activity reduction of GPX and the intensity of NSS. © 2018

The introduction of a new psychopharmaceutical medication instead of the previous one always poses a certain challenge. In the case of antipsychotics (AP), these problems are considerably more complicated and are mainly caused by the question of dose equivalents, but also by the pharmacokinetic properties of the drug. In the case of partial dopamine D2 agonists, an additional issue is the possibility of deterioration when switching from the previous D2 antagonists to these drugs. Cross-titration is therefore generally recommended. Finally, due to the capsule form, it is not possible to increase the dose of cariprazine by less than 1.5 mg during titration. In this paper, we have presented our proposal to replace the most commonly used second-generation APs with the third-generation AP cariprazine. We have taken into account the dose equivalents, the pharmacological forms of the drugs and their pharmacokinetic and pharmacodynamic properties.

Aim: This paper evaluates the clinical efficacy, safety, and practical implications of Trazodone Prolonged Release (PR) in managing depression, anxiety, and sleep disorders, with a focus on its multimodal mechanism of action and advantages over traditional therapies. Methodology: A critical review of recent literature (2020–2024) [1, 2–3] was conducted, analyzing data from clinical trials, real-world studies, and European treatment guidelines to assess the pharmacodynamics, pharmacokinetics, and therapeutic outcomes of Trazodone PR. Results: Trazodone PR demonstrates efficacy in addressing complex symptoms of depression, anxiety, and sleep disturbances, with a favorable safety profile and reduced risk of sexual dysfunction and weight gain compared to other antidepressants. Its ability to modulate serotonin, norepinephrine, dopamine, and histamine systems enhances mood, sleep quality, and cognitive recovery. Conclusion: Trazodone PR is a versatile and well-tolerated treatment option for patients with comorbid conditions and treatment-resistant cases. Its multimodal action, combined with benefits like improved neuroplasticity through BDNF production, makes it a suitable choice for the long-term management of mood disorders and associated conditions [4, 5–6]. © The Author(s) 2025.
