Virpax Pharmaceuticals products
Virpax - Model Envelta - Endogenous Enkephalin Intranasal Spray
Endogenous peptides with analgesic potential include endorphins via binding to the mu receptor, dynorphins via the kappa receptor and enkephalins via the delta receptor. Kappa and delta opioid agonists have been shown to provide analgesic benefit while sparing mu agonist toxicity1. Preclinical data supports analgesia from enkephalin without significant opioid tolerance or drug liking. Typically, exogenous enkephalins are rapidly degraded and have difficulty accessing the CNS2. Using a novel encapsulation method known as Molecular Envelope Technology (MET), leucine-enkephalin, or L-ENK can be delivered via an intranasal formulation of “protected” nanoparticles. MET increases dwell time in the nares promoting delivery via the olfactory route across the blood brain barrier and into the central nervous system.
Virpax - Model Probudur - Injectable Long-Acting Bupivacaine Hydrogel
Ultra-Long-Acting Local Anesthetics: Liposomal Encapsulated Bupivacaine; Sustained Non-Opioid Pain Management in Prolonged Field Care and Hospital Settings.
Virpax - Model NobrXiol - Intranasal Pharmaceutical-Grade Cannabidiol (CBD)
Benefits: NobrXiol may be using significantly less pharmaceutical-grade CBD than current FDA approved oral CBD dosing. NobrXiol may achieve higher efficiency via the nasal route and reduce peripheral side effects like dose dumping due to high-fat meals. Since peripheral exposure via the plasma will be reduced by the nose to brain delivery, we believe there will be negligible liver first-pass metabolism. NobrXiol may not be metabolized in the liver avoiding drug to drug interactions caused by oral pharmaceutical-grade CBD. By avoiding the first pass effect Intranasal NobrXiol may eliminate enzymatic degradation or deactivation. Enzymatic deactivation occurs when an enzyme changes the structure of a neurotransmitter so that the receptor no longer recognizes the neurotransmitter.
