Self-Medication with Drotaverine among Patients with Common Abdominal Symptoms and Treatment Efficacy from the Perspectives of Patients and General Practitioners-An Observational, Retrospective, Cross-Sectional Study Using Real-World Data.

In Poland, drotaverine is the most frequently purchased antispasmodic, yet there is a paucity of real-world data on its use. We evaluated the profiles of patients who used drotaverine, and we investigated prescription patterns among general practitioners (GPs). In this cross-sectional, questionnaire-based study, we asked patients who purchased drotaverine about their reasons for using it, its perceived efficacy, satisfaction with treatment, and physician consultation. We also asked GPs about the status of drotaverine in their practice. Among 650 recruited patients, 74% used drotaverine for pain, 67% for cramps, and 19% for abdominal discomfort. Approximately 83% of patients purchased drotaverine without a physician's advice. Patients who used it after a physician's advice were more frequently female, older, and less educated. For all symptoms, mean severity scores decreased by ~5 points (0-10 scale) after the first dose. Ninety-eight percent of patients were satisfied with drotaverine. Among 210 GPs, the percentages prescribing drotaverine were: 42% for irritable bowel syndrome, 89% for cholelithiasis, 60% as supportive therapy for urinary infections, 89% for nephrolithiasis, and 75% for menstruation pain. The GPs perceived drotaverine as more useful, effective, and tolerable than other drugs for abdominal pain or cramps. Drotaverine significantly reduced the severity of all symptoms for which it was taken, and it was perceived as effective and tolerable.
