DIAZGRANADOS, Jesús Alberto et al. Efficacy of Lamotrigine in epilepsy patients resistant to drug tratments in a neurological reference center in the city of Cali. Acta Neurol Colomb. [online]. 2015, vol.31, n.2, pp.127-133. ISSN 0120-8748.  https://doi.org/10.22379/2422402219.

Introduction: Epilepsy is a common neurological condition with an estimated incidence of 50 per 100,000 population and a prevalence five to ten per 1,000 population in developed countries. It is considered refractory when seizures are so frequent that the patient's ability to live fully is limited, when treatment does not control seizures, or when side effects are limiting for the normal development of the person. Lamotrigine is an antiepileptic drug that inhibits the sodium channel voltage-dependent presynaptic modulating excitatory transmitter glutamate and aspartate type. Objective: To determine the effectiveness of Lamotrigine as monotherapy or in combination with conventional antiepileptic drugs in patients with refractory epilepsy. Materials and methods: A descriptive study. Period May 2009 to November 2012. Variable analysis by frequency, averages and ratios. Results: Sample: 115 medical records. 97.4% (112) of the patients have reduced the number of seizures, so than 85.2% (98) have had a reduction greater than or equal to 50%. There was an average of 9.45 attacks per month, with a median of 6 episodes, prior to treatment with this medicine, whereas after administering medication, the average was 3.65 episodes per month, with a median of 1 crisis/month. The average drugs used before initiating the Lamotrigine was 1.9 with a minimum of 1 and maximum of 6 and from the beginning of the Lamotrigine the average was 1.54, with minimum use of 1 and maximum of 4 drugs. Conclusion: Lamotrigine is a last generation drug with great effectiveness and few side effects, which can effectively reduce the frequency of seizures in patients with refractory epilepsy.
