ahhh..... there was some research done on Beagels...... please share the following with your vet and let us know what he/she advices.
This is a recent research article (which i do not have fu access to)
https://analyticalsciencejournals.onlin ... .201601232 .... HOWEVER... i did find results from a similar study listed in an FDA publication
https://www.fda.gov/media/71693/download (see page 12) with the results listed as follows:
3.2 Animal Pharmacology/Toxicology
The sponsor provided responses (final study reports) to Pediatric Written Request -
Amendment #5 for pediatric studies with aciphex dated June 27, 2007. In the written
request, the sponsor was asked to conduct 1) a 4-week repeated dose toxicity study in
neonatal rats, and 2) a 90-day repeated dose toxicity study in neonatal dogs with aciphex.
In the 5-week juvenile rat study (282 male and 282 female, Study 900948), SpragueDawley rat from Days 7 to 41 post-partum were exposed to 5, 25, or 150 mg/kg
rabeprazole by oral gavage for 5 weeks. Treatment increased the serum gastrin
concentrations and stomach weight. Histopathological examination revealed a doserelated increase of cytoplasmic eosinophilia of chief cells in gastric mucosa. The gastric
mucosal thickness was also increased in the high dose males and females. The mean
density of ECL cells was increased in males at 5 mg/kg or higher and females at 25

mg/kg or higher. The changes were reversible. The NOAEL of the 5-week study in rats
was 25 mg/kg.
In the 90-day oral toxicity study in neonatal dogs, rabeprazole was given by oral gavage
to 7 days old dogs (31 male and 32 female Beagle dog pups) at 0, 3, 10, and 30
mg/kg/day (Study 900949). Treatment increased the serum gastrin level, stomach weight
and gastric mucosal thickness. Histopathological examination revealed degeneration
/necrosis of parietal cells and mucosal hypertrophy/ hyperplasia at the fundus of the
stomach in a dose-related manner. The changes were reversible. The NOAEL of the 90
day study in dogs was 3 mg/kg.
In a previous 104-week carcinogenicity study in Sprague-Dawley rats, rabeprazole at 5
mg/kg/day induced gastric enterochromaffin-like (ECL) cell hyperplasia in male and
female rats. At the same dose level, rabeprazole also induced ECL cell carcinoid tumors
in female rats (Aciphex label).
The Pharmacology and Toxicology reviewer Dr. Ke Zhang commented that the 5-week
oral toxicity study in the neonatal rats and the 90-day oral toxicity in neonatal dogs are
acceptable, and that there were no new toxicities or target organ of toxicity identified in
these studies as compared to the adult animals. Completion of these studies in neonatal
rats and dogs satisfied the requirements of the Pediatric Written Requests (in Amendment
#5 dated June 27, 2007).
