Quanil Drug Interactions

Choline supplementation has been associated with decreasing urinary excretion of carnitine in young adult women.
A study concluded that chronic treatment with lithium enhances the effects of choline in the brain. A preliminary report of MRI studies did not observe a significant positive relationship between increases in brain choline and increases in brain lithium.
CDP-choline can cause an increase in plasma concentrations of dopa.
Methotrexate may diminish pools of all choline metabolites. Choline supplementation reverses fatty liver caused by methotrexate administration in rats.
Pentazocine exhibits neuromuscular blocking effects in part through a depressive action on cholinoceptive sites on the nerve motor end terminals, presenting a possible interaction if administered with choline.
Although a few studies have linked choline with partially reversing the effects of scopolamine, a later study failed to demonstrate similar effects.
Choline is a product of the breakdown of succinylcholine. Taking choline with succinylcholine may theoretically intensify effects and/or toxicity.
Interactions with Herbs and Supplements: Choline, via its metabolism to betaine, works in concert with vitamins B₆, B₁₂, and folic acid in the metabolism of the potentially atherogenic substance homocysteine.
