Clinical study to investigate the efficacy and safety of an ointment that increases the blood circulation in the skin, containing 2.5% Nicoboxil and 0.4% Nonivamide, in comparison to ointments that contain only one of both compounds, or none of them (placebo) for the treatment of acute low back pai

- Primary Outcome Measures
Name Time Method Main Objective: The objective of this trial is to demonstrate superior efficacy of a hyperemisation-inducing ointment containing 2.5% Nicoboxil/0.4% Nonivamide over 2.5% Nicoboxil and 0.4% Nonivamide and placebo for the treatment of acute low back pain in patients aged 18 to 65 years ;Secondary Objective: Not applicable;Primary end point(s): - The primary endpoint is the pain intensity difference (PID) from pre-dose baseline 8h after the 1st application. <br><br>Pain intensity (PI) will be assessed using an 11-point numerical rating scale (NRS) ranging from 0 = ‘no pain’ to 10 = ‘worst pain possible’. Patients will assess their low back pain intensity in a diary pre-dose and at 0.5, 1, 2, 3, 4, 6 and 8 hours) after the first ointment application on day 1.;Timepoint(s) of evaluation of this end point: pre-dose baseline and 8 hours after the first application
- Secondary Outcome Measures
Name Time Method Secondary end point(s): - Pain intensity difference (PID) from pre-dose baseline 4h after the 1st application<br>- Difference of average PI from pre-dose baseline on the last individual treatment day<br>- Patient assessment of efficacy on the last individual treatment day <br>;Timepoint(s) of evaluation of this end point: - Pain intensity difference (PID) from pre-dose baseline 4h after the 1st application. Timepoints: predose baseline and 4h after 1st application.<br>- Difference of average PI from pre-dose baseline on the last individual treatment day. Timepoints: pre-dose baseline and last individual treatment day.<br>- Patient assessment of efficacy on the last individual treatment day. Timepoint: last individual treatment day.<br>The last individual treatment day is the last study day, where the patient has recorded any ointment applications in the patient diary. <br>The patient will assess on the NRS scale the average PI at the end of each treatment day in the diary.
