Research in the International Journal of Nano and Biomaterials has demonstrated how microcrystalline cellulose (MCC) can be used to soak up the drug amitriptyline in cases of overdose. Amitriptyline is a commonly prescribed tricyclic antidepressant, used to manage depression, chronic pain, and mood disorders. It is, as with many prescription medicines, also a drug of abuse as well as representing a potential lethal risk to users through overdose.
