Abstract:
A single-center, open-label, four-way crossover study was performed in 22 healthy adult subjects to determine the relative effect and significance of certain foods on the bioavailability of nizatidine. Results indicate that administration of nizatidine mixed with apple sauce, cranberry juice, or vegetable juice reduces the bioavailability approximately 30--40% relative to administration of a nizatidine capsule with water. The reduction of bioavailability appears to be primarily due to reduced extent of absorption. The mechanism of this effect was not investigated.
