Topical delivery of muscarinic receptor antagonists prevents and reverses peripheral neuropathy in female diabetic mice. (PubMed, J Pharmacol Exp Ther) - "We measured plasma concentrations of the M receptor-selective muscarinic antagonist pirenzepine when delivered by subcutaneous injection, oral gavage, or topical application to the skin and investigated efficacy of topically delivered pirenzepine against indices of peripheral neuropathy in diabetic mice...Topical delivery of muscarinic antagonists may serve as a practical therapeutic approach to treating diabetic and other peripheral neuropathies. SIGNIFICANCE STATEMENT: Muscarinic antagonist pirenzepine alleviates diabetic peripheral neuropathy when applied topically in mice."
