Brief summary
This is a pilot study designed to evaluate the safety, tolerability of Topiramate (TPM) + N-Acetyl Cysteine (NAC) in combination versus Topiramate (TPM) + placebo for the treatment of alcohol use disorder (AUD).
Detailed description
This is a pilot study designed to evaluate the safety, tolerability of Topiramate (TPM) + N-Acetyl Cysteine (NAC) in combination versus Topiramate (TPM) + placebo in 16 subjects enrolled in a 12 week, randomized, double-blind, outpatient trial. Each subject will receive randomly one of the drug combinations for 12 weeks plus medication management. Primary Aim 1: To evaluate the safety, tolerability of Topiramate (TPM) and N-Acetyl Cysteine (NAC) in combination or Topiramate (TPM) + placebo for the treatment of Alcohol Use Disorder (AUD). This aim will be accomplished by testing the following: •Hypothesis 1 - The combination of Topiramate (TPM) and N-Acetyl Cysteine (NAC) will be well tolerated by participants as evidenced by less self-report cognitive side effects (word finding difficulties, difficulties with concentration, and confusion). Secondary Aim 1: The combination of Topiramate (TPM) and N-Acetyl Cysteine (NAC) or Topiramate (TPM) + Placebo will reduce alcohol drinking. This aim will be accomplished by testing the following: •Hypothesis 2 - The combination of Topiramate (TPM) and N-Acetyl Cysteine (NAC) or Topiramate (TPM) + Placebo will reduced alcohol drinking , as evidenced by a statistically significant reduction in percentage of heavy drinking days (PHDD) as compared to baseline.
