FDA says, clinical testing of the new implant was as effective as buprenorphine in sublingual-film form, 63% of patients having no evidence of opioid in use of  Six months usage compared with 64% of patients taking the sublingual form. It must be regulated by a trained professional and it having a risk of abuse if removed from the skin, FDA is needs a Risk Evaluation and Mitigation Strategy (REMS) for the drug.
