Acura Pharmaceuticals is working to provide accurate dosages of powerful drugs while preventing drug abuse. The company has developed a technology to add abuse-deterring agents to commonly abused pharmaceuticals. If a drug with these agents (what Acura calls Aversion Technology) is crushed and inhaled, certain ingredients will cause nasal irritation, and if an abuser attempts to dissolve the powder, it will form a non-injectable gel. Its Impede Technology works with pseudoephedrine to disrupt the process used to turn the decongestant into meth. Acura's approved products include prescription Aversion oxycodone and over-the-counter Nexafed (pseudoephedrine with Impede ingredients).
