I read with great interest the recent article by Shah et al. [1] Interestingly, the past few years have seen the emergence of lacosamide as a novel new agent in the management of neuropathy associated pain besides its role in managing seizures.
For instance, lacosamide is effective in ameliorating pain secondary to neuropathies induced by chemotherapeutic agents such as vincristine [2] Lacosamide at a daily dose of 400 milligrams is also effective in decreasing pain associated with diabetic neuropathy [3] Lacosamide is also effective in the treatment of pain associated with trigeminal neuralgias [4] Lacosamide induces these anti- nociceptive effects by accentuating the slow inactivation of voltage gated sodium channels in neurons [5] In fact, recent studies show that lacosamide appears to be more effective in ameliorating neuropathic pain in comparison to agents such as pregabalin.
Besides this, lacosamide has also been shown to attenuate hyperalgesia in patients with pain syndromes such as Dejerine-Roussy syndrome [6] Lacosamide also attenuates osteoarthritis associated pain [7] Interestingly, lacosamide seems to be more effective in ameliorating pain in female animal models in comparison to male animal models [3]
Intravenous lacosamide is a faster alternative for pain relief in comparison to oral lacosamide [6] Side effects associated with locasamide are relatively few. In fact, Wymer et al. in a recent study reported that only 8% of patients administered locasamide for neuropathic pain abandoned the study due to side affects of the drug [8] Clearly, further studies are needed to confirm these analgesic effects of lacosamide. The coming few years may very well see the emergence of lacosamide as a potent agent for control of neuropathic pain besides its role in controlling seizures.
