In certain embodiments, the article includes dimensions configured for transesophageal administration with a gastric resident system. In some cases, the article may be configured to control drug release e.g., with zero-order drug kinetics with no potential for burst release for weeks to months. In some embodiments, the articles described herein comprise biocompatible materials and/or are safe for gastric retention. In certain embodiments, the article includes dimensions configured for transesophageal retrieval.
