Yes, you can, especially if the medication is used as directed by your doctor. 

Debrutir Forte (Sodium butyrate) has no known interactions with Ketrel (quetiapine) because sodium butyrate is not absorbed from the gastrointestinal tract and does not affect the metabolism of other medicines.

Therefore, it is safe to take Debrutir Forte together with Ketrel, but it is always advisable to consult a doctor before introducing a new drug to therapy, especially when using a psychotropic drug such as Ketrel.
