Sublingual Aripiprazole After Gastric Bypass: Recommendation

Rationale for Sublingual Formulation Preference

Gastric bypass fundamentally disrupts medication absorption by bypassing the duodenum and proximal jejunum, which are the primary absorption sites for most oral medications 1
Extended-release and standard oral formulations are particularly problematic because reduced gastric acid exposure and accelerated intestinal transit compromise drug uptake 1
This route avoids the anatomical changes of gastric bypass, including bypassed stomach, duodenum, and proximal jejunum that compromise oral medication bioavailability 1

Patients with gastric bypass have increased rates of depression and other psychiatric disorders and require comprehensive mental health assessment 2
Post-bariatric surgery patients are at increased risk for substance use, worsening depression/anxiety, and suicidal ideation, necessitating regular psychiatric follow-up 2
