Please check the member agreement fr preauthrizatin guidelines. Prspective review is nt required. Nte: This plicy addresses the use f buprenrphine as a maintenance treatment f piate addictin and nt the use f rapid withdrawal regimens. Descriptin: The Fd and Drug Administratin (FDA) has apprved tw frms f buprenrphine, Subutex r Buprenex (buprenrphine hydrchlride) and Subxne (buprenrphine hydrchlride and nalxne hydrchlride in a 4:1 rati), fr the treatment f piate dependence. These drugs treat piate addictin by preventing symptms f withdrawal frm herin r ther piates and thereby reducing addictin behavirs. Federal law (DATA, the Drug Addictin Treatment Act) allws physicians t administer and/r prescribe buprenrphine fr addictin treatment, including a maintenance phase whereby the drug may be utilized indefinitely. The law was intended t create greater access t piid addictin treatment prgrams by facilitating the creatin f a chrt f physician ffice treatment prgrams and an allwance fr prescriptins fr self-administratin f the agents, when clinically apprpriate. In cntrast, methadne maintenance requires facility-based treatment and direct administratin f the drug. The use f these agents in medicatin-assisted treatment f piid addictin is regulated by federal and state statute. Buprenrphine with nalxne (Subxne) is used as an alternative t methadne fr the maintenance treatment f piate addictin. The drug is less rigidly cntrlled than methadne because it has a lwer ptential fr abuse and is less dangerus in an verdse. The intentin f adding nalxne t the frmulatin is t deter misuse. Buprenrphine is pharmaclgically related t mrphine and is a partial piid agnist: It has the same effect n mu-pid receptrs in the brain as des herin r ther piate drugs, but it has a ceiling affect whereby higher dses d nt result in higher effects. Buprenrphine, when used crrectly, reduces r eliminates withdrawal symptms assciated with piid dependence but des prduce the euphria and sedatin caused by herin r ther piates. Hwever, warnings exist that bth frmulatins have the ptential fr abuse and prduces dependence f the piid type. Als, buprenrphine has been assciated with significant respiratry depressin, and several deaths have ccurred when addicts intravenusly misused the drug, usually cncmitantly with benzdiazepines (sedative/hypntics) r ther depressants such as alchl and ther piids. Treatment is cnducted in phases as described belw. Inductin:

2 Patients must be assessed fr piid dependence and apprpriateness fr buprenrphine therapy. Once judged apprpriate, patients may start treatment with buprenrphine alne r buprenrphine with nalxne. As nalxne is an antagnist, withdrawal may be precipitated when it is used. Therefre, patients n higher dses f lng-acting narctics will typically be treated with buprenrphine alne r cnverted t shrt-acting drugs r first underg reductin in dses. They may als experience significant withdrawal regardless f buprenrphine administratin and require symptmatic therapies. Patients are instructed t discntinue their piids and are scheduled t be seen in the ffice at a time when they wuld begin t experience withdrawal symptms. The presence f these symptms is assessed and if present, the buprenrphine is administered usually at a dse f 4 mg (2-8 mg). The patient is bserved fr relief f withdrawal signs and symptms r adverse effects. Symptms are typically relieved in minutes. If cntrlled, the patient is usually bserved lnger and at apprximately 2-4 hurs given a secnd 4 mg dse. Rarely, sme patients with high likelihd f breakthrugh withdrawal are sent hme with a third nighttime dse. The patients are then seen daily t assess whether withdrawal is cntrlled. Dses are adjusted as needed until a stable dse is fund. A dse f nt greater than 16 mg is maintained fr several days befre dsage escalatin t allw steady state equilibratin. Usually the target daily dse is determined r the maximum daily dse is reached by three days and administratin can be changed t nce daily. Stabilizatin: The gal f the stabilizatin phase is t attempt t reach a daily maintenance dse within 1-2 weeks. Patients started n buprenrphine withut nalxne are cnverted t the cmbined prduct. Dses greater than 32 mg are nt generally needed. Patients are regularly assessed fr adherence, use f illicit drugs, intxicatin r withdrawal and satisfactin. A Treatment Imprvement Prtcl guidelines (TIP 40) recmmend that initial and nging drug screening shuld be used t detect r cnfirm the use f recent use f drugs which culd cmplicate patient management. Urine screening is the mst cmmnly used testing methd. Maintenance Therapy: Once stable, patients enter maintenance therapy, which may last indefinitely. It may be assciated with gradual dse reductins (medical withdrawal) and eventual eliminatin f treatment, r there may be an indefinite cntinuance t avid relapse f addictin. Dsage and Administratin f Subxne: Subxne treatment is intended fr use in adults and adlescents mre than 16 years f age and is administered sublingually as a single daily dse. The recmmended target dse is in the range f 12 t 16 mg/day. The pill is placed underneath the tngue until it has fully disslved and typically will be absrbed within minutes. As patients prgress n therapy, the physician may write a prescriptin fr a take-hme supply f the medicatin. Physician Qualificatins: The Drug Addictin Treatment Act (DATA) requires that befre physicians begin prescribing buprenrphine they must ntify the Secretary f Health and Human Services-specifically the Divisin f Pharmaclgic Therapies (DPT) within the Center fr Substance Abuse Treatment (CSAT)-f their intent t treat patients with this prduct. CSAT will in turn ntify the Drug Enfrcement Administratin (DEA) if, and when, the prvider is qualified as required by DATA. Only thse physicians wh have apprval frm the DEA are able t start

3 in-ffice treatment and prvide prescriptins fr nging medicatin. The CSAT maintains an active database t help individuals lcate qualified dctrs. Buprenrphine treatment must be cmbined with cncurrent behaviral therapies and with the prvisin f needed scial services by the primary treating physician. Therefre, qualified physicians must be able t prvide r refer patients fr these services. Only physicians may be qualified in accrdance with DATA. Other prfessinals with prescriptive privileges by state law are nt eligible t be qualified. Drug Testing and Other Cmpliance Mnitring: Peridic testing fr use f ther piates r illicit substances r alchl misuse is expected in the management. Usually urine screening is perfrmed during initial phases f treatment and randmly eight times a year. In rder t be sure patients are nt diverting medicatin, they may be required t reprt at randm intervals t the ffice with their pill supply t be sure it is cnsistent with the prescribed use (i.e., n pills are missing.) Physicians must maintain careful recrds f prescribed dses. (Dispensed dses require exact narctic administratin recrds). Blue Crss & Blue Shield f Rhde Island (BCBSRI) may reprt t the prescribing physician regarding the prescriptin payment histry and assess whether the patient receiving buprenrphine is receiving ther piates. The use f piates t cntrl acute pain may be apprpriate, but such use is very cmplex when used in cnjunctin with subxne due t antagnist affects, tlerance, and risk f ver-dsage. Therefre, patients cncmitantly receiving piates and buprenrphine wuld be unusual when the agents are used in a clinically apprpriate manner. BCBSRI may als mnitr physicians t be sure that they are qualified by CSAT and prescribing in cnfrmance with the regulatins. NOTE TO THE PRESCRIBER: The prescriber is respnsible t adhere t the SAMHSA regulatins fr addictin treatment under the prvisins f the Drug Addictin Treatment Act f 2000 (DATA 2000). The prescriber is respnsible fr cmplying with all assciated state and federal piid treatment and maintenance prtcls as they relate t physician qualificatins, privacy and cnfidentiality f the patient, dispensing and prescribing f buprenrphine prducts, recrd keeping and crdinating treatment with addictin and psychiatric treatment prgrams. Medical Criteria: Office-based treatment f piid dependence requires the fllwing: Diagnsis f piid dependence , , Member has been infrmed n safe and effective alternatives t treatment and has chsen this methd f treatment and understands the ptential risks and benefits, and is willing and able t fllw the treatment plan.
