Subutex 2 – Sublingual Buprenorphnim

Subutex is a medication that contains the active ingredient buprenorphine. It is a partial opioid agonist, meaning it activates opioid receptors in the brain but to a lesser extent than full opioid agonists like heroin or oxycodone. Subutex is primarily used in the treatment of opioid addiction and is taken sublingually (under the tongue) in tablet form.

How does Subutex work?

Subutex works by binding to the same opioid receptors in the brain that are targeted by other opioids. However, because it is a partial agonist, it produces less of the euphoric effects and respiratory depression associated with full opioid agonists. This makes it a useful medication for reducing cravings and withdrawal symptoms in individuals who are addicted to opioids.

What are the differences between Subutex and Suboxone?

Subutex and Suboxone are both medications used in the treatment of opioid addiction, but they contain different combinations of active ingredients. Subutex contains only buprenorphine, while Suboxone contains both buprenorphine and naloxone. Naloxone is an opioid antagonist, meaning it blocks the effects of opioids and can precipitate withdrawal symptoms if taken by someone who is physically dependent on opioids.

The addition of naloxone in Suboxone is intended to discourage misuse of the medication. When taken as prescribed, the naloxone in Suboxone has little to no effect because it is poorly absorbed sublingually. However, if Suboxone is crushed and injected, the naloxone can antagonize the effects of the buprenorphine and precipitate withdrawal symptoms.

What are the side effects of Subutex?

Common side effects of Subutex may include constipation, nausea, vomiting, headache, dizziness, sweating, insomnia, and anxiety. More serious side effects, although rare, can include respiratory depression, allergic reactions, and liver problems. It’s important to discuss any concerns or potential side effects with a healthcare professional.

Is Subutex still available?

The brand name Subutex has been discontinued, but generic versions of the medication are available. The generic versions contain the same active ingredient, buprenorphine, and are used for the same indications.

Is Subutex effective for treating opioid addiction?

Subutex has been shown to be effective in the treatment of opioid addiction when used as part of a comprehensive treatment program that includes counseling and psychosocial support. It helps to reduce withdrawal symptoms and cravings, allowing individuals to focus on their recovery. However, the effectiveness of any medication may vary from person to person, and it’s important to work closely with a healthcare professional to determine the most appropriate treatment approach.

Usual Adult Dose for Opiate Dependence – Maintenance

SUBLINGUAL Tablets: Following a 2-day induction:

• Adjust dose in 2 to 4 mg increments/decrements to a level that holds patient in treatment and suppresses opioid withdrawal signs and symptoms
• Target dose: 16 mg sublingually once a day; range 4 to 24 mg/day
• Maximum dose: 24 mg/day; higher doses have not shown a clinical advantage

Comments:

• Buprenorphine with naloxone is the preferred drug for maintenance treatment; unsupervised maintenance treatment with buprenorphine should be limited to those who cannot tolerate buprenorphine-naloxone.
• When determining prescription quantity for unsupervised administration, consider the patient’s level of stability, the security of his or her home situation, and other factors likely to affect the ability to manage supplies of take-home medications.

Usual Adult Dose for Pain

Initial dose: 0.3 mg deep IM or slow IV (over at least 2 minutes); may repeat this dose once after 30 to 60 minutes if needed; then, 0.3 mg IV/IM every 6 hours as needed

• A single 0.6 mg IM dose may be given to patients who are not in a high risk category (see Warnings)

Maximum single dose: 0.3 mg (IV) or 0.6 mg (IM)

Usual Adult Dose for Opiate Dependence – Induction
