Brief summary: Magnesium exerts analgesic effects in several animal pain models and in patients affected by acute postoperative pain and chronic pain of neuropathic origin. There is no evidence that magnesium can modulate pain in patients with peripheral arterial occlusive disease (PAOD).

We describe the protocol of a single-center randomized double-blind clinical trial aimed at assessing the efficacy of oral magnesium supplementation in controlling severe pain in patients with advanced PAOD.

Detailed description: * Adult patients admitted to our Acute Pain Service for intractable pain will be eligible if they are affected by PAOD at stages III and IV of Lèriche-Fontaine classification, and are opioid-naïve.
* Patients enrolled will be randomized to the control group, treated with standard therapy, consisting of an oral administration of oxycodone 5 mg and pregabalin 25 mg per day plus placebo (fructose 10 g) twice a day for two weeks, or to the experimental group, treated with magnesium oxide 300 mg twice a day.
* Randomization will be computer-generated, with allocation concealment obtained using opaque, sequentially numbered and sealed envelopes. Trials participants, care providers, data collectors, outcome assessors and data analysts will be blinded to treatment allocation.
* Patients will be evaluated on the day of hospital admission (day 0) and on days 2, 4, 6, 8, 12, and 14 with the following information being collected: daily oxycodone dose received; patient's perceived average and maximum pain using the Numerical Rating Scale (NRS: 0=no pain to 10=worst possible pain); pain relief using Pain Relief Scale (PRS: 0% no pain relief to 100% complete pain relief); characteristics of the pain, using the Neuropathic Pain Scale (NPS: 10 items); impact of pain on the patient's daily activities, using the Brief Pain Inventory (BPI; 9 items).
* A sample size calculation performed for the primary outcome showed that 150 patients (75 per group) are needed to achieve 90% power to detect a minimum reduction of 30% in oxycodone dosage in the experimental group, after allowing for a drop-out rate of around 20%.
* Ethical approval of the study protocol has been obtained from Comitato Etico Provinciale di Brescia, Brescia, Italy.

Eligibility criteria: Inclusion Criteria:

* adult patients (18 years or above)
* PAOD at stages III and IV according to the Lèriche-Fontaine classification
* no treatment with opioids at the time of recruitment

Exclusion Criteria:

* renal failure (serum creatinine ≥ 2.0 mg/dl);
* congestive heart failure (New York Heart Association, NYHA \> 3);
* treatment with digoxin and/or calcium channel blockers;
* pre-existing neuromuscular diseases;
* chronic diarrhea;
* acute limb ischemia successfully treated with interventional angiography, Fogarty embolectomy and/or surgical revascularization.
