Addiction is a functional brain disease that seriously endangers human physical and mental health. It causes neuroplastic changes in the brain regions involved in cognition, memory, reward, motivation formation, behavioral decision-making, and driving in addicts, disrupting the balance of their normal functions and creating pathological balance relationships, leading to strong psychological dependence on addictive substances and/or certain behaviors. The opioid addiction represented by heroin is a typical substance addiction, and patients often relapse due to the inability to persist in taking anti relapse drugs. Therefore, it is crucial to completely quit opioid drugs and prevent relapse! However, anti relapse drugs such as naltrexone hydrochloride tablets have definite therapeutic effects, but patients have poor adherence to medication. The key is to improve medication adherence.

    Naltrexone is an opioid receptor antagonist, and its binding activity with opioid receptors is more than 30 times that of heroin, an opioid drug. Therefore, when the concentration of naltrexone in the body reaches a certain level, it can effectively antagonize the vast majority of opioid receptors, preventing heroin and other drugs from producing pleasure. The drug blocks the production of drug use pleasure and achieves anti relapse treatment effects.

    The principle of action of naltrexone hydrochloride implant is to evenly disperse/encapsulate naltrexone drug molecules in a release medium of polylactide, and administer them subcutaneously; Slowly and evenly releasing drugs, occupying opioid receptors for a long time, and antagonizing the pleasure produced by opioid drugs; Gradually restore the normal distribution of neural synapses and neurotransmitters; Ultimately relieve mental dependence and relapse into opioid drugs.
