Naltrindole

Naltrindole is a research chemical that specifically blocks certain receptors in the brain called delta-opioid receptors. These receptors are involved in the body's responses to pain, mood regulation, and other functions. By attaching to these receptors without activating them, naltrindole prevents natural or drug-related substances from binding and exerting their effects. This makes it a useful tool for scientists studying pain mechanisms and opioid effects. It is primarily used in laboratory research and is not approved for medical treatment.
