| E.1 Medical condition or disease under investigation |
| E.1.1 | Medical condition(s) being investigated |
Acute otitis media (AOM) is an acute inflammatory disease involving the mucosa of the middle ear. AOM is one of the most frequent complications of upper respiratory tract infections in children.
Treatment of AOM requires use of drugs with antipiretic, analgesic and antinflammatory action, as well as antibiotics. |
|
| E.1.1.1 | Medical condition in easily understood language |
| Acute otitis with pain and fever requires administration of drugs to treat increased temperature and to reduce pain as well as antibiotics and topical agents (e.g. nasal drops). |

| MedDRA Classification |
| E.1.3 | Condition being studied is a rare disease | No |
| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
1. To investigate the analgesic effect of the study drugs Ibuprofen oral suspension 20 mg/ml and Ibuprofen oral suspension 40 mg/ml (ear pain relief assessed by Pain rating scale) in children with AOM.
2. To investigate the antipyretic effect of the study drugs Ibuprofen oral suspension 20 mg/ml and Ibuprofen oral suspension 40 mg/ml (reduction of axillary temperature) in children with AOM.
3. To investigate the anti-inflammatory effect of the study drugs Ibuprofen oral suspension 20 mg/ml and Ibuprofen oral suspension 40 mg/ml (reduction of laboratory markers of inflammation) in children with AOM.
4. To examine the effect of the study drugs Ibuprofen oral suspension 20 mg/ml and Ibuprofen oral suspension 40 mg/ml on appetite, sleep, and playing activity in children with AOM.
5. To evaluate the safety of the study drugs Ibuprofen oral suspension 20 mg/ml and Ibuprofen oral suspension 40 mg/ml based on frequency and severity of treatment-related adverse events. |
