Results Overview

In a double-blind clinical trial, we compared two active drugs (mamantine vs. valproate) three months after initiation, looking for changes in the average number of days of migraine attack presentation per month and comparing the three months before with the three months after treatment administration with two active drugs.

PRIMARY outcome

Timeframe: Three months before treatment (Pretreatment), three months after initiating treatment (post-treatment)

Population: It was a straightforward difference between pre and post-treatment in both groups.

In a double-blind clinical trial, we compared two active drugs (mamantine vs. valproate) three months after initiation, looking for changes in the average number of days of migraine attack presentation per month and comparing the three months before with the three months after treatment administration with two active drugs.

PRIMARY outcome

Timeframe: Three months previous and three months after the treatment.

Population: The intensity of pain was measurable by VAS (visual analogous scale) pre and post-treatment.

The possible reduction in the average on the visual analog scale (0-10) comparing three months before and after three months of the treatment with both drugs. We measured both arms of the study. 0 means without pain. 10 means the worst possible pain in the concept of the patient.

PRIMARY outcome

Timeframe: Three months.

Population: MIDAS (Migraine Disability Assessment Score) is a critical evaluation to see the difference between pre and post-treatment with the active drugs we are evaluating.

To compare the average of Memantine against the group that receives Valproate before and after starting preventive treatment. Using the Migraine Disability Assessment scale (The score is the sum of days missed from work or school, days of housework missed, days of missed non-work activities, and days of work or school plus days of housework in which productivity in the last three months) to compare punctuation changes. The MIDAS score is divided into four degrees, the minimum score is 0 points, and the maximum score is 70. A higher value represents a higher difficulty to carry out a satisfactory lifestyle, and a score higher than 20 points already represents a high limitation to enjoying daily activities: Grade I (0-5 points): Slight limitations and few patient treatment needs. Grade II (6-10 points): Moderate limitations and treatment needs. Grade III (11-20 points) and IV (21 or more points): Severe and significant punctuation treatment needs.

Timeframe: Three months

Population: The final analysis was made on a total of 33 participants. However, six left the study because we were in a pandemic situation.

The number of adverse events and the safety of memantine and valproate. Evaluated according to CTCAE v5.0. There were several side effects, but no one had life-threatening or serious side effects.
