Interaction Details
There were no interactions found between Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate and Passion Flower. This does not mean the potential for an interaction does not exist, however. There is often a lack of studies and data surrounding traditional medicine, especially concerning drug interactions, so it is important to always consult your provider before making any changes to your medication regimen.
Pharmacist Analysis
Passionflower is not known to have many clinically significant drug interactions.
Nevertheless, it has been shown to have sedative effects, which can be additive when used in conjunction with sedative medications (e.g., Benadryl, benzodiazepines, opioids, etc...).
Therefore, we do list interactions between Passionflower and CNS (central nervous system) depressants or other drugs with strong sedative effects.
Additionally, certain constituents of Passionflower (such as apigenin and vitexin) may inhibit certain drug transports, specifically OATP2B1 and OATP1A2.
These are responsible for the uptake of certain drugs and other compounds into the body.
As Passionflower can inhibit these transports, it is possible that it might reduce the bioavailability of drugs that are substrates for these transporters but studies are far from conclusive on the matter.
There is no known drug interaction between Passionflower and the drug in question here, however.
As always, be sure to speak with your doctor before making any changes to your medication regimen.

Calcium Oxybate, Magnesium Oxybate, Potassium Oxybate, Sodium Oxybate Overview
-
Calcium, magnesium, potassium, and sodium oxybate is used to treat attacks of cataplexy (episodes of muscle weakness that begin suddenly and last for a short time) and excessive daytime sleepiness in adults and children 7 years of age and older who have narcolepsy (a sleep disorder that may cause extreme sleepiness, sudden uncontrollable urge to sleep during daily activities, and cataplexy). Calcium, magnesium, potassium, and sodium oxybate is also used to treat adults who have idiopathic hypersomnia (IH; a sleep disorder that may cause excessive daytime sleepiness and uncontrollable urge to sleep during daily activities despite adequate or prolonged nighttime sleep). Calcium, magnesium, potassium, and sodium oxybate is in a class of medications called central nervous system depressants. Calcium, magnesium, potassium, and sodium oxybate works to treat narcolepsy, cataplexy, and idiopathic hypersomnia by reducing activity in the brain.
