Ranitidine Acarbose

ACARBOSE H2 RECEPTOR BLOCKERS -RANITIDINE 1 blood levels of ranitidine Possibly due to 1 absorption of ranitidine Be aware... 

Rosiglitazone has been studied in combination with acarbose, digoxin, metformin, nifedipine, ranitidine, warfarin, and oral contraceptives [67,72] There have been no clinically significant effects on the pharmacokinetics of any of these agents in combination with rosiglitazone. 

Cimetidine appears to reduce the clearance of metformin, and may have contributed to a case of metformin-associated lactic acidosis. Cimetidine did not alter repaglinide pharmacokinetics, and ranitidine did not alter pioglitazone or rosiglitazone pharmacokinetics. Acarbose did not alter ranitidine pharmacokinetics, but miglitol decreased the AUC of ranitidine by 60%. 

The manufacturer of acarbose notes that it had no effect on the pharmacokinetics or pharmacodynamics of ranitidine in healthy subjects. Conversely, the manufacturer of miglitol notes that it reduced the bioavailability of ranitidine by 60%. ...
