about the coating:
Reduced Medication EffectivenessThe shorter intestinal length after gastric bypass or duodenal switch surgery can make extended-release drug preparations less effective. Some extended-release drugs include antidepressants (Wellbutrin XL), anxiolytics and sleep medications (Xanax XR), and anti-hypertensives (Toprol XL, Verapamil XL). Because these formulations are intended to be absorbed over 2-12 hours, the pills may pass through the gastrointestinal tract before absorption is complete.
This same principle also applies to delayed-release and enteric- or film-coated pills, which are coated with a material that prevents the medication from being released until the pill moves through the stomach to the small intestine. (Sometimes the abbreviation “EC” is added to the name of a drug to indicate that it is enteric-coated.) Immediate-release dosage forms should be substituted, although they may need to be taken more often.
