Genetic Predictors of Analgesic Efficacy of Propranolol for Treating Postoperative Pain (PRO_GENE_POP)

Contribution of COMT Haplotypes in Propranolol Analgesic Efficacy for Treating Post-surgical Pain After Laparoscopic Hemicolectomy

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.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Placebo Comparator: IV-PCA morphine + Placebo PO

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.

Morphine delivered via IV-PCA pump for 48 hours after surgery with standard program: bolus 1 mg, lock out 7 minutes, no background infusion.
Other Names:
  • Patient controlled Analgesia with intravenous morphine
Placebo tablets administered with the same schedule of Propranolol tablets
Other Names:
  • tablet containing microcrystalline cellulose
Assessment of PPT (Pressure Pain Threshold) by pressure algometer and assessment of the post-op area of hyperalgesia by von Frey hair no. 16.
Other Names:
  • Pressure Pain Threshold and Hyperalgesia test
Questionnaires assessing for sleep quality (PSQI: Pittsburgh Sleep Quality Index), pain quality (sfMGPQ-Short Form-McGill Pain Questionnaire), somatization-depression-anxiety (SCL-90-R: Symptom Checklist 90 Revised), evolution of post-operative chronic pain (PQRS: Post-operative Quality of Recovery Scale)
Other Names:
  • PSQI, sfMGPQ, SCL-90-R, PQRS
Assessing of High Pain Sensitivity (HPS), Average Pain Sensitivity (APS) and Low Pain Sensitivity (LPS) haplotypes for COMT by genotyping peripheral blood samples.
Other Names:
  • HPS, APS, LPS
Experimental: IV-PCA morphine + Propranolol PO

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.
