Lexaria Bioscience Announces Positive Blood-Brain-Barrier Results

Lexaria's technology delivered 195% more nicotine across the blood-brain-barrier

  • Lexaria’s technology delivered 195% more nicotine across the blood-brain-barrier conceptually allowing for smaller micro doses in accordance with developing FDA policies.
  • Lexaria’s formulation was 4x faster at reaching its peak level in brain tissue than the non-enhanced control formulation.
  • Lexaria Nicotine subsidiary formation complete.

Lexaria Bioscience Corp. LXRP LXX:CNX, a drug delivery platform innovator, announces further results from its recently completed second-generation study in 40 rats (two groups of 20 each) in addition to those released on August 7, 2018.

Lexaria had previously announced partial results from the in vivo study to evaluate the ability of Lexaria’s DehydraTECH™ technology to deliver nicotine as quickly as 2 minutes after oral administration. The nicotine polacrilex was delivered in a water solution that utilized Lexaria’s patented DehydraTECHTM process and as previously reported, delivered 90.2% more nicotine over the first 10 minutes of the study than the concentration-matched control formulation by the 10-minute mark (95% CI; p=0.044).
