Beta-Fuoxymorphamine

Beta-Funaltrexamine (also known as β-FNA and B-FNA) is a potent and long-lasting opioid antagonist. It is derived from naltrexone and is used in scientific research.

Chemistry[edit | edit source]

Beta-Funaltrexamine is a derivative of naltrexone, a morphinan derivative and a pure opioid antagonist. It is structurally similar to other opioid antagonists such as naloxone and nalorphine.

Pharmacology[edit | edit source]

Beta-Funaltrexamine acts as an antagonist at the mu opioid receptor, one of the three main types of opioid receptors in the body. It has a high affinity for this receptor and acts by blocking the effects of opioid agonists.

Uses[edit | edit source]

Beta-Funaltrexamine is primarily used in scientific research. It is used to study the role of the mu opioid receptor in pain, addiction, and other conditions.

Side Effects[edit | edit source]

As an opioid antagonist, Beta-Funaltrexamine can precipitate withdrawal symptoms in individuals who are physically dependent on opioids. Other potential side effects include nausea, vomiting, and increased pain sensitivity.
