H3 histamine receptor antagonist pitolisant reverses some subchronic disturbances induced by olanzapine in mice.

Pitolisant: A Desert Oasis for Olanzapine-Induced Side Effects

Olanzapine, an atypical antipsychotic drug, can cause side effects like sedation and depression-like symptoms. It's like a thick fog descending upon the desert, obscuring the traveler's vision and dampening their spirits. Pitolisant, an H3 histamine antagonist, is being explored as a potential antidote to these side effects. It’s like a refreshing desert breeze, clearing the fog and restoring clarity and energy. This research investigates the effect of pitolisant on olanzapine-induced side effects in mice.

Clearing the Fog: Pitolisant Reverses Olanzapine Side Effects

The use of atypical antipsychotic drugs like olanzapine is associated with side effects such as sedation and depression-like symptoms, especially during the initial period of the use. It is believed that the occurrence of these undesirable effects is mainly the result of the histamine H1 receptors blockade by olanzapine. In addition, use of olanzapine increases the level of triglycerides in the blood, which correlates with growing obesity. The aim of this study was to investigate the influence of pitolisant - H3 histamine antagonist - on subchronic olanzapine-induced depresion-like symptoms, sedation and hypertriglicerydemia. Forced swim test was conducted to determinate depressive-like effect of olanzapine and antidepressive-like activity during the co-administered pitolisant. The test was performed after the first and fifteenth day of the treatment of the mice. The spontaneous activity of the mice was measured on the fourteenth day of the treatment with a special, innovative RFID-system (Radio-frequency identification system) - TraffiCage (TSE-Systems, Germany). Triglyceride levels were determined on the sixteenth day of the experiment after 15 cycles of drug administration. Daily olanzapine treatment (4 mg/kg b.w., i.p., d.p.d) for 15 days significantly induces sedation (p < 0.05) and prolongs immobility time in forced swim tests (FST) in mice (p < 0.05); and also elevates the level of triglycerides (p < 0.05). Administration of pitolisant (10 mg/kg b.w., i.p.) subsequent to olanzapine normalizes these adverse effects.

A Refreshing Breeze in the Desert of Antipsychotic Side Effects

This research suggests that pitolisant could be a valuable tool for mitigating the side effects of olanzapine, like a refreshing desert breeze clearing the fog and restoring clarity and energy. It’s a promising development, potentially improving the experience of patients taking olanzapine and enhancing their overall well-being.

Dr.Camel's Conclusion

Pitolisant, like a refreshing oasis in the desert of olanzapine-induced side effects, offers a potential way to improve the treatment experience for patients taking this medication. It’s a promising development with the potential to enhance their quality of life and well-being.
