Interaction Details
Oxybutynin is classified as belonging to the following category: Cytochrome P450 3A4 (Cyp3A4) Substrates
Theoretically, kratom might increase the levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research shows that kratom extract inhibits CYP3A4 enzyme activity. Additionally, there is one case report of a 27-year-old male who died from neuroleptic malignant-like symptoms after concomitant use of kratom and quetiapine, a CYP3A4 substrate. Although it did not appear that the patient had consumed large quantities of quetiapine, postmortem plasma levels were in the lethal range, indicating possible inhibition of CYP3A4 by kratom.

Oxybutynin Overview
-
Oxybutynin is used to treat overactive bladder (a condition in which the bladder muscles contract uncontrollably and cause frequent urination, urgent need to urinate, and inability to control urination) in certain adults and children. Oxybutynin is also used as an extended-release tablet to control bladder muscles in adults and children 6 years of age and older with spina bifida (a disability that occurs when the spinal cord does not close properly before birth), or other nervous system conditions that affect the bladder muscles. Oxybutynin is in a class of medications called anticholinergics/antimuscarinics. It works by relaxing the bladder muscles.
