Domperidone to Treat Symptoms of Gastroparesis: Benefits and Side Effects from a Large Single-Center Cohort.

Abstract

BACKGROUND:

There is increased awareness about risks and benefits of using domperidone to treat gastroparesis.

AIM:

To describe the outcome of treating patients with refractory gastroparesis symptoms with domperidone.

METHODS:

Domperidone 10 mg QID or TID was prescribed to patients with refractory gastroparesis symptoms; follow-up obtained at 2-3 months assessing symptoms and side effects. Patients filled out Patient Assessment of Upper GI Symptoms prior to treatment and at follow-up along with Clinical Patient Grading Assessment Scale (CPGAS, +7 = completely better; 0 = no change).

RESULTS:

Of 125 patients initially prescribed domperidone, 7 did not take this medication and 3 were lost to follow-up. Of the 115 known patients treated with domperidone, 88 had idiopathic, 16 diabetic, and 9 postsurgical gastroparesis. Side effects were reported by 44 patients (most common-headache, tachycardia/palpitations, diarrhea); 14 patients stopped treatment. Hundred and one patients were seen at follow-up taking domperidone (2.4 ± 2.7 months, average dose 36 ± 13 mg/day). CPGAS averaged 2.7 ± 2.7 (p < 0.01) with 69 patients reporting symptom improvement and 45 patients at least moderately improved with CPGAS ≥ 4. Improvements were seen in most symptoms, especially postprandial fullness, nausea, vomiting, and stomach fullness.

CONCLUSIONS:

In this large single-center study of patients treated with domperidone, side effects necessitating discontinuing treatment occurred in 12 %. The majority of patients remaining on treatment experienced an improvement in symptoms of gastroparesis, particularly postprandial fullness, nausea, vomiting, and stomach fullness. Thus, domperidone treatment is beneficial for many patients with symptoms of gastroparesis. This study provides needed benefit and risk information concerning treating patients with domperidone.
