So apparently there is a way for Imodium to cross the blood brain barrier through the use of Azithromycin (Zithromax) or any antibiotic in that same class. I found some scientific information online a year or so ago, but am damned if I can find it now. Does anyone know how much Imodium and Zithromax it would take to pass Imodium through? Has anyone tried it? If there is a thread about it already created, please point me in that direction. Thank you. I tried searching for the combination of the two and found nothing.
