Buprenorphine, sold under the brand name Subutex, among others, is an opioid used to treat opioid use disorder, acute pain, and chronic pain.It can be used under the tongue, in the cheek, by injection, as a skin patch, or as an implant. For opioid use disorder, it is typically started when withdrawal symptoms have begun and for the first two days of treatment under direct observation of a health care provider. The combination formulation of buprenorphine/naloxone (Suboxone) is recommended to discourage misuse by injection. Maximum pain relief is generally within an hour with effects up to 24 hours.
Side effects may include respiratory depression (decreased breathing), sleepiness, adrenal insufficiency, QT prolongation, low blood pressure, allergic reactions, and opioid addiction. Among those with a history of seizures, there is a risk of further seizures.Opioid withdrawal following stopping buprenorphine is generally less severe than with other opioids.it is unclear if use during pregnancy is safe and use while breastfeeding is not recommended.Buprenorphine affects different types of opioid receptors in different ways. Depending on the type of receptor it may be an agonist, partial agonist, or antagonist.
Buprenorphine was patented in 1965 and approved for medical use in the United States in 1981.In 2017, 14.6 million prescriptions for the medication were written in the United States. It is also a common drug of abuse, being used in place of heroin. Buprenorphine may be used recreationally by injection or in the nose for the high it produces. In the United States, it is a Schedule III controlled substance.For the tablets, the wholesale cost in the United States is between US$0.86 and US$1.32 per daily dose as of 2017.
Opioid use disorder
Buprenorphine is used to treat people with opioid use disorder.The combination formulation of buprenorphine/naloxone is generally preferred as naloxone, an opioid antagonist, has a higher bioavailability intravenously and results in acute withdrawal if the formulation is crushed and injected.Prior to starting buprenorphine, individuals should wait long enough after their last dose of opioid until they have some withdrawal symptoms to allow for the medication to bind the receptors, but if taken too soon, buprenorphine can displace other opioids bound to the receptors and precipitate an acute withdrawal. The dose of buprenorphine is then adjusted until symptoms improve, and individuals remain on a maintenance dose through treatment.
Buprenorphine versus methadone
Both buprenorphine and methadone are medications used for detoxication and opioid replacement therapy and appear to have similar effectiveness based on limited data and are safe for pregnant women with opioid use disorder.In the US, only designated clinics can prescribe methadone for opioid use disorder in which people starting treatment must follow-up daily, which may be appropriate for those requiring a more structured environment. Alternatively, buprenorphine can be prescribed by any clinician with a waiver allowing people to receive treatment as a part of their routine care.
A transdermal patch is available for the treatment of chronic pain. These patches are not indicated for use in acute pain, pain that is expected to last only for a short period of time, or pain after surgery, nor are they recommended for opioid addiction.
With respect to equianalgesic dosing, when used sublingually, the potency of buprenorphine is about 40 to 70 times that of morphine.When used as a transdermal patch, the potency of buprenorphine may be 100-115 times that of morphine.
Adverse effects.buy subutex online
Common adverse drug reactions associated with the use of buprenorphine are similar to those of other opioids and include: nausea and vomiting, drowsiness, dizziness, headache, memory loss, cognitive and neural inhibition, perspiration, itchiness, dry mouth, shrinking of the pupils of the eyes (miosis), orthostatic hypotension, male ejaculatory difficulty, decreased libido, and urinary retention. Constipation and CNS effects are seen less frequently than with morphine.
The most severe side effect associated with buprenorphine is respiratory depression (insufficient breathing).It occurs more often in those who are also taking benzodiazepines, alcohol, or have underlying lung disease.The usual reversal agents for opioids, such as naloxone, may be only partially effective and additional efforts to support breathing may be required.Respiratory depression may be less than with other opioids, particularly with chronic use. However, in the setting of acute pain management, buprenorphine appears to cause the same rate of respiratory depression as other opioids such as morphine.
Buprenorphine treatment carries the risk of causing psychological or physical dependence. Buprenorphine has a slow onset and a long half-life of 24 to 60 hours. Once a person has stabilized on the medication, there are three options: continual use, switching to buprenorphine/naloxone, or medically supervised withdrawal.
