This study is a randomized, double-blind, placebo controlled clinical trial. The main purpose of this study is to determine if postsurgical pain ratings are improved with treatment with oral Propranolol, and if the effectiveness of treatment can be modified by the presence or absence of SNPs (Single Nucleotide Polymorphism) associated with Cathecol-O-MethylTransferase (COMT) and mu-opioid receptor (MOR1) activity. The treatment period will last for three days and the observation period will last for six months. Effectiveness of treatment will be assessed by means of morphine consumption through quantitative evaluation of IV-PCA (Patient Controlled Analgesia) morphine as primary outcome measure.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| IV-PCA morphine + Placebo PO | Placebo Comparator | Pain control after surgery will be performed through IV-PCA morphine. Placebo will be administered with the same schedule of Propranolol in the experimental arm. Parallel evaluation of Quantitative Sensory Testing (QST), Psychometric assessment and COMT-haplotypes will be included along the trial. |
|
| IV-PCA morphine + Propranolol PO | Experimental | The morning of the surgery a dose of Propranolol 20 mg PO will be administered. After surgery pain control will be performed with IV-PCA morphine; in addition a second dose of Propranolol 20 mg PO will be administered . During the first and second postoperative day Propranolol 30 mg PO (BID) will be administered. Parallel assessment of Quantitative Sensory Testing (QST), Psychometric assessment and COMT-haplotypes will be included along the trial. |
