Does Magnesium Oxide help with digestion?

Conclusion: Magnesium oxide and naldemedine are most likely effective for prevention of OIC in cancer patients. Naloxone in a fixed combination with oxycodone, naldemedine and methylnaltrexone effectively treat OIC in cancer patients with acceptable adverse events. However, their effect has not been compared to standard (osmotic and stimulant) laxatives. More studies comparing standard laxatives with each other and with opioid antagonists are necessary before recommendations for clinical practice can be made.

Conclusion: Polyethylene glycol is probably more effective than placebo and key comparator therapies and should be considered the standard of first-line care. Future studies should consider polyethylene glycol as an index therapy, and clearly describe methods, patient characteristics, and previous therapeutics.
