Pantoprazole has minimal CYP2C19 inhibitory activity compared with omeprazole, making it the preferred PPI choice in patients on clopidogrel.

                                Pantoprazole + Levothyroxine
                            
                        

                        
                        
Like all PPIs, pantoprazole reduces gastric acid and impairs levothyroxine tablet dissolution, leading to decreased T4 absorption and potentially under-treated hypothyroidism.
