FAQs About Naltrexone Hydrochloride API Powder

What is naltrexone?

Naltrexone is a medication that is primarily used to help manage alcohol dependence and opioid dependence. It works by blocking the effects of opioids in the brain and reducing the pleasurable effects and cravings associated with alcohol and opioids.
What are active pharmaceutical ingredients?

Active pharmaceutical ingredients (APIs) are the substances in a pharmaceutical drug that are biologically active. In other words, APIs are the components that produce the intended effects or therapeutic action in the body.
What is naltrexone powder used for?

Naltrexone powder is the raw, unformulated form of the drug. It is used as an API for manufacturing finished pharmaceutical products, such as tablets or capsules, that are used to treat alcohol and opioid dependence.
What is the difference between naltrexone and naltrexone hydrochloride?

Naltrexone refers to the basic, active drug. Naltrexone hydrochloride is the hydrochloride salt form of naltrexone, which improves its stability and makes it suitable for use in tablets or oral solutions. Most medications contain the hydrochloride salt.
What is naltrexone hydrochloride?

Naltrexone hydrochloride is the hydrochloride salt form of naltrexone, used in pharmaceutical formulations. It is used for managing alcohol and opioid dependence by blocking opioid receptors in the brain.
How long does it take for naltrexone hydrochloride to work?

For opioid blockade, naltrexone starts working within about 1 hour after oral administration. For alcohol dependence, it may take several days to weeks to notice a reduction in cravings and alcohol intake.
What are the negative effects of naltrexone?

Common side effects include: Nausea Headache Dizziness Fatigue Insomnia Anxiety Rare but serious effects: Liver damage (especially at high doses) Allergic reactions
How does naltrexone affect sleep?

Naltrexone can cause insomnia or sleep disturbances in some people. However, effects on sleep can vary—some report vivid dreams or trouble falling asleep, but others do not notice significant changes.
Is naltrexone the same as morphine?

No, naltrexone is NOT the same as morphine. Morphine is an opioid painkiller (agonist). Naltrexone is an opioid antagonist (it blocks the effects of opioids like morphine).
What to avoid when taking naltrexone?

Opioid medications or illicit drugs: Naltrexone will block their effects and may cause withdrawal if you are physically dependent on opioids. Certain painkillers: Avoid opioid or morphine-based painkillers. Alcohol: While naltrexone is for alcohol dependence, combining it with large amounts of alcohol or other drugs can increase side effects. Hepatotoxic drugs: Avoid drugs that can cause liver harm, if your liver function is impaired.
Is naltrexone a painkiller?

No, naltrexone is not a painkiller. In fact, it blocks the pain-relieving effects of opioid pain medications.
Will naltrexone make me gain weight?

Naltrexone is not commonly associated with weight gain. In some weight loss medications (like Contrave®, a combination of naltrexone and bupropion), it is actually used to help with weight loss.
What is naltrexone hydrochloride made of?

Naltrexone hydrochloride is a synthesized chemical compound. Its structure is derived from the modification of thebaine, a naturally occurring opioid, through chemical synthesis processes; it is not made from natural plant extracts. The HCl (hydrochloride) part is added to form a stable, water-soluble salt suitable for medications.
