Maintenance Once symptoms of opiate withdrawal and use of other opioids has been significantly decreased or eliminated, the maintenance phase begins. Dose increases may occur either because the patient is continuing illicit opioid use while apparently selleck chemical Abiraterone complying with the buprenorphine (monitored dosing may be necessary), or because the patient complains that the dose is not sufficient. Changing the frequency or scheduling of the buprenorphine doses may improve the latter. Although buprenorphine has a long half -life, some patients report

better results by dosing 3 times/day, eg, 8 mg AM, PM, and late evening. Inhibitors,research,lifescience,medical The final dose is usually 8 to 24 mg/day103 but some patients appear to need 32 mg. If illicit opioid use continues in spite of high buprenorphine doses and therapy, referral for methadone maintenance or depot naltrexone may be necessary.

Other issues Acute pain Acute pain is more difficult to manage with buprenorphine compared with a full agonist, but there are a number of options. These include dividing the daily buprenorphine dose into 3 or 4 doses and adding nonopioid analgesics; adding a full ju opioid analgesic on top of the buprenorphine dose; switching the patient temporarily over to a short-acting full ยต agonist and increasing the dose until adequate pain relief occurs; or using nonopioid ways of dealing with pain such as regional or general anesthesia in a hospital setting.
