neurontin
2 interactions related to neurontin
gabapentin + antacids
Aluminum and magnesium-containing antacids reduce the bioavailability of gabapentin by approximately 20% when taken simultaneously, and magnesium oxide specifically can reduce gabapentin AUC by up to 43%. The mechanism is reduced intestinal absorption, not pH-related (proton pump inhibitors do not cause the same effect).
