50 Years - 65 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  • Patients with pain due to bilateral peripheral neuropathy caused by type 2 diabetes mellitus.

5. Study Description

Brief Summary
Management of symptoms associated with diabetic neuropathy is a difficult issue for clinicians since it usually does not respond to standard analgesics. Resveratrol is a naturally occurring plant-derived, polyphenolic compound, it exerts pleiotropic activity. The investigators believed that the implementation of multidisciplinary approaches including pharmacotherapy and provision of healthcare professional services such as pharmacist intervention are needed for alleviation of diabetic associated neuropathy.Therefore, the hypothesis of the present protocol is that the administration of resveratrol and/or provision of pharmaceutical care in patients with diabetic neuropathy might be of value in improving quality of life and managing diabetic neuropathic pain.The study is designed as a four-arm randomized, placebo-controlled clinical trial. Group one will be given only conventional hypoglycemic drugs. Group two patients will receive conventional hypoglycemic drugs accompanied by pharmacist interventions. Group three; patients will receive resveratrol 500 mg orally once daily after meals for three months, in addition to their regular hypoglycemic drugs. Group four; patients will receive resveratrol 500 mg orally once daily after meals along with their regular hypoglycemic drugs for a period of three months, accompanied by pharmacist interventions. Neuropathic pain will be measured by various neuropathic pain assessment tools. Nerve conduction studies will be performed to assess the effect of interventional therapy. The expected outcome will be the improvement of diabetic neuropathy associated symptoms along with glycemic status.
Detailed Description
Diabetic neuropathy is the most common microvascular complication of diabetes, resulting from prolonged periods of hyperglycemia, damaging fragile nerve fibers and the walls of their blood vessels. Despite clinical developments in the treatment of diabetes complications, especially diabetic neuropathy, it still remains a clinical challenge with no effective solution. Conventional therapies such as anti-epileptics, opioid analgesics, and antidepressants for the treatment of neuropathic pain are quite challenging due to their serious adverse effects. There is a need to investigate novel effective and safe options. Recently, polyphenols have also been introduced as potential neuroprotective agents in diabetes. Alleviation of the symptoms associated with diabetic neuropathy and exerting preventive measures to halt the emergence of neuropathy complications are crucial priorities, and this requires multidisciplinary approaches including pharmacotherapy and provision of healthcare professional services such as pharmacist intervention. Aim of the study: to evaluate the effects of resveratrol and pharmaceutical care on the severity of diabetic neuropathy and improvement in the quality of life of diabetic patients. Study design: four-arm randomized, double-blind, placebo-controlled clinical trial. Interventions:Therapeutic intervention and Pharmacist intervention. Number of participants = 120 Number of groups = 4 groups each of 30 patients
