Hypothesis

Can once daily dosing of Acetyl-L-Carnitine achieve similar plasma levels as twice daily dosing in HIV-1 infected patients with toxic peripheral polyneuropathy?

Conclusion

Once daily dosing of Acetyl-L-Carnitine can achieve similar plasma levels as twice daily dosing, but the clinical effects need further investigation.

Supporting Evidence

  • Patients receiving ALCAR had higher pre-dose levels than control subjects.
  • Post dose levels were not significantly higher than pre dose levels in any treatment group.
  • All ALCAR plasma levels were significantly higher in the treatment groups compared to controls.

Takeaway

This study looked at whether taking a medicine called Acetyl-L-Carnitine once a day works just as well as taking it twice a day for people with HIV and nerve problems.

Methodology

A crossover trial where 23 HIV-1 infected subjects switched from twice daily to once daily dosing of Acetyl-L-Carnitine, with plasma levels measured pre and post dose.

Limitations

The study size was small, and results need to be interpreted with caution.

Participant Demographics

23 HIV-1 infected subjects, slightly more men in the treatment group, mean age 43 years.

Statistical Information

P-Value

p<0.02 for ALCAR levels, p<0.03 for L-carnitine levels.

Statistical Significance

p<0.05
