Objective: To analyze the clinical factors considered by general practitioners for the prescription of prokinetic or antisecretory drugs in patients with functional dyspepsia (FD), and to assess therapeutic outcomes and factors predicting effectiveness.
Design: Multicentric, prospective and observational study.
Patients: 1,021 patients with FD were included. One hundred and thirty-two (132) were excluded from the analysis because they were taking ASA or NSAID. Patients were classified according to their predominant symptoms as reflux, ulcer, dysmotility or non-specific. At the physician discretion, treatment with alkali drugs was prescribed to 38 patients, prokinetic drugs to 574, antisecretory drugs to 123 and a combined therapy to 154. One month later, patient self-perception of symptomatic improvement was evaluated in patients treated with prokinetic drugs and antisecretory drugs.
Results: 85% of the patients reported symptomatic improvement after one month of treatment. Patients with non-specific FD had lower improvement rates regardless of the drug used (prokinetic or antisecretory) (77%) compared to all the other types (p = 0.03). Prescription of prokinetics was associated to female gender (OR: 0.43; 95% CI: 0.28-0.66) and early satiety (OR: 2.5; 95% CI: 1.6-4.1). A longer symptomatic evolution (OR 0.92: 95% CI: 0.88-0.97) was the only independent predictive factor of a poor response to prokinetic drugs.
Conclusions: Among patients with FD attended by general practitioners, female gender and early satiety symptom were associated to the prescription of prokinetic drugs. Early symptomatic effectiveness rates for prokinetic or antisecretory drugs alike were high (85%). Patients with non-specific dyspepsia or long symptomatic evolution showed less favorable symptomatic response to prokinetic drugs.
