OBJECTIVE: Describe and characterize treatment patterns, satisfaction, improvement in pain and functional impairment (health-related quality of life [HRQoL]) in users of over the counter (OTC) Voltaren gel diclofenac (VGD) 2.32% and 1.16% in a real-world setting.
METHODS: This observational real-world German study had prospective and retrospective components. The prospective data were collected from electronic surveys completed by adults who purchased VGD to treat their musculoskeletal pain at baseline and 4 and 12 weeks after baseline. Retrospective data were from a 12-month (March 2019 to February 2020) abstraction from dispensing software platforms used in select German pharmacies.
RESULTS: Surveys from 467 participants (mean age 60.8 years) were analyzed. Average pain severity at baseline was 6.0 on an 11-point Numeric Rating Scale (0 = no pain, 10 = worst possible pain), improving by 0.8 and 1.2 points at Weeks 4 and 12, respectively. Performance of functional activities (daily/physical/social activities and errands/chores) improved and the proportion of participants with at least moderate interference decreased at both follow-up timepoints. Retrospective analyses indicated that majority of patients receiving VGD (n = 95,085) were ≥65 years old (67.9%), had one dispensed tube (70.8%) and did not switch to another topical treatment (including other NSAIDs) (77.3%), and were co-prescribed at least one cardiovascular medication (74.3%).
CONCLUSIONS: This study provides the first real-world insights into OTC VGD use in Germany. The participants using VGD reported a decrease in pain severity and an improvement of HRQoL while under treatment, as well as resulting satisfaction with treatment. Patients infrequently switched to alternate topical therapies/NSAIDs.
