Cerebrolysin is a drug consisting of low-molecular-weight neurotrophic peptides and free amino acids. Cerebrolysin has been shown to ameliorate the effects of oxidative stress, reduce apoptosis, and promote neuronal growth in several degenerative and acquired central nervous system insults, including dementias, stroke, and traumatic injuries. Little is known about its therapeutic efficacy in peripheral nervous system diseases. In this study, we clinically evaluated the effects of cerebrolysin on peripheral nervous system lesions. We evaluated the clinical efficacy of cerebrolysin in six patients with the following conditions who failed to respond to conventional therapies: (1) atonic bladder due to inflammatory radiculitis; (2) paraplegia due to inflammatory radiculoneuropathy; (3) post-traumatic brachial plexopathy; (4) compressive radial nerve injury; (5) post-traumatic facial nerve paralysis; and (6) diabetic ophthalmoplegia. Our results showed that cerebrolysin was more associated with rapid neurological recovery after various peripheral nerve lesions than other therapies including steroids and supportive therapies such as vitamins and antioxidants. The present results support the therapeutic efficacy of cerebrolysin in the treatment of acquired peripheral nervous system diseases.
