Study summary

Olanzapine is a thieno-benzodiazepine derivate that is effective managing the symptoms of schizophrenia and reducing the psychopathological symptoms of psychosis. It is also effective in controlling the acute manic episodes associated with bipolar disorder, and have provided some therapeutic advantages over other antipsychotic agents (Citrome et al., 2019).

However, Ola administration has been reported to induce profound BWG accompanied with higher incidence of metabolic deficits, such as hypertension, diabetes and hyperlipidemia, as compared to other antipsychotic agents (Mauri et al., 2014).

Adjunctive treatment with other agents that can minimize or normalize Ola-induced BWG can enhance the safety and tolerability profiles of an effective antipsychotic, thus highlighting the need to develop improved therapies or interventions to minimize these side effects. A meta-analysis of 12 published studies found that antidiabetic drugs such as metformin improved metabolic parameters in patients treated with antipsychotics (de Silva et al., 2016).

These studies encouraged the evaluation of other antidiabetic agents as adjunctive therapies to minimize Ola-induced BWG. Empagliflozin (EMPA)is the third-generation anti-diabetic drug acting as sodium-glucose transport protein two inhibitor (SGLT2), which provides a new mechanism of action to improve glycemic control with modest decreases in systolic blood pressure and body weight (Pradhan et al., 2019). The effects of EMPA on Ola-induced BWG have not been determined and require further investigation.

What researchers measure

Primary outcomes

  1. Change in body weight and body mass index (BMI)

    a person's weight in kilograms (or pounds) divided by the square of height in meters and measure of body fat based on height and weight that applies to adult men and women body mass index = wt (kilogram) divideed by height in meter square

    Time frame: up to 12 weeks

Secondary outcomes

  1. Adverse events (AE) as measures of safety and tolerability of Empagliflozin

    any side effects of the used intervention

    Time frame: up to 12 weeks
