Efficacy and Safety in the Combination of Ibuprofen / Loratadine Versus Ibuprofen Versus Loratadine

Phase III longitudinal, multicenter, randomized, double-blind clinical trial. The aim of this study is to evaluate the efficacy and safety of the drug combination of Ibuprofen/Loratadine versus Ibuprofen versus Loratadine as monotherapy for the symptomatic treatment of the common cold.

Researchers will compare the fixed-dose combination of Ibuprofen + Loratadine versus Ibuprofen versus Loratadine for the symptomatic treatment of the common cold. The adverse events related to the interventions will be registered during follow up.

In the event that the symptoms worsen or the patient's clinical condition warrants the use of any additional medication, the principal investigator or designated physician will be in charge of prescribing it according to the individual clinical condition and the physical examination, this will be recorded as "Concomitant medication".

Participants will:

* Be randomized into one of the 3 intervention groups (A,B,C)
* Visit the clinic at day 0 (day of enrollment) and at day 7
* Answer the first symptomatic related survey at the randomization visit (V0) and the following ones in the morning when they wake up, the last survey will be answered at the final visit (day 7)
