Terminal elimination half-life is approximately 12-15 hours in patients with normal renal function, allowing for twice-daily dosing.
Primarily metabolized by cytochrome P450 (CYP) 2D6 with minor contributions from CYP3A4 and CYP2C19. Active metabolite N-desmethyl lorcaserin is formed via CYP2D6.
Primarily hepatic via CYP3A4 and CYP3A5 to norbuprenorphine (active metabolite); also undergoes glucuronidation.
Primarily renal (60-70% unchanged) with 20-30% fecal via biliary elimination; less than 5% metabolized.
Approximately 60-80% of a dose is excreted renally as unchanged drug, with 20-40% eliminated via biliary/fecal routes.
95% bound to albumin and alpha-1-acid glycoprotein.
Approximately 95-98% bound to plasma proteins, primarily albumin.
0.3-0.4 L/kg; indicates moderate distribution to extracellular fluid and well-perfused tissues.
Volume of distribution is approximately 2-3 L/kg, indicating extensive tissue distribution beyond plasma volume.
Oral: 40-50% (first-pass effect); Subcutaneous: 70-80%; IV: 100%.
Oral bioavailability is approximately 70-80%.
No dose adjustment required for mild to moderate renal impairment (e GFR ≥30 m L/min/1.73 m2). Contraindicated in severe renal impairment (e GFR <30 m L/min/1.73 m2) or end-stage renal disease.
e GFR <45 m L/min/1.73m²: contraindicated. e GFR ≥45: no adjustment.
No dose adjustment required for mild hepatic impairment (Child-Pugh class A). Not recommended for moderate or severe hepatic impairment (Child-Pugh class B or C) due to lack of data.
Child-Pugh Class A: no adjustment; Class B: reduce to 200 mg once daily; Class C: contraindicated.
Not approved for use in pediatric patients under 18 years of age. Safety and efficacy have not been established.
Not recommended for patients under 18 years; safety and efficacy not established.
No specific dose adjustment required; initiate at 0.5 mg subcutaneously once weekly and titrate cautiously due to potential for renal function decline and increased sensitivity. Monitor renal function and consider dose reduction if e GFR declines.
No specific dose adjustment; monitor renal function and use caution due to increased risk of adverse effects.
WARNING: SUICIDALITY AND ANTIDEPRESSANT DRUGS - Antidepressants increased the risk of suicidal thoughts and behavior in children, adolescents, and young adults in short-term studies. Monitor for worsening and emergence of suicidal thoughts and behaviors. DELCOBESE is not approved for use in pediatric patients.
Risk of respiratory depression, especially in non-opioid-tolerant patients. Risk of neonatal opioid withdrawal syndrome with prolonged use during pregnancy. Risk of serious injury or death due to accidental exposure in children.
Risk of serotonin syndrome or neuroleptic malignant syndrome when coadministered with other serotonergic drugs. Potential for pulmonary hypertension. Monitor for valvular heart disease (5-HT2B receptor agonist activity). Caution in patients with renal impairment (e GFR <30 m L/min). Avoid in pregnancy (potential for fetal harm).
Respiratory depression, particularly in the first 24-72 hours of treatment; caution in patients with pulmonary disease. Risk of QT prolongation. Adrenal insufficiency. Severe hypotension. Risk of misuse, abuse, and addiction. Tolerance and physical dependence.
Concomitant use with monoamine oxidase inhibitors (MAOIs) or within 14 days of discontinuing an MAOI. Known hypersensitivity to DELCOBESE or any component. Severe renal impairment (e GFR <30 m L/min) or end-stage renal disease. History of pulmonary hypertension. Pregnancy.
Hypersensitivity to buprenorphine or any component of the formulation. Severe respiratory insufficiency. Acute or severe bronchial asthma. Gastrointestinal obstruction, including paralytic ileus.
Avoid grapefruit and grapefruit juice which inhibits CYP3A4 metabolism increasing DELCOBESE levels. Avoid high-fat meals as they increase absorption and risk of adverse effects. Limit alcohol to no more than 1 drink per day due to additive CNS depression. Ensure adequate hydration to prevent constipation.
No significant food interactions. Grapefruit juice may increase buprenorphine levels; avoid large quantities.
DELCOBESE is contraindicated in pregnancy. First trimester exposure is associated with increased risk of major congenital malformations, particularly neural tube defects, cardiac anomalies, and cleft palate. Second and third trimester exposure can cause fetal growth restriction, oligohydramnios, and neonatal renal impairment. There is a dose-dependent risk of pregnancy loss.
Supr ENza (testosterone) is contraindicated in pregnancy due to virilization of female fetus. First trimester: high risk of clitoromegaly, labial fusion, and urogenital sinus abnormalities. Second and third trimesters: risk of continued virilization, including phallic enlargement and ambiguous genitalia. Fetal growth restriction may occur.
Excretion into breast milk is unknown; due to potential for serious adverse reactions in the breastfed infant, breastfeeding is not recommended during therapy and for at least 1 week after the last dose. No M/P ratio data available.
Testosterone is present in breast milk; M/P ratio not reported. Avoid breastfeeding due to potential for androgenization of the infant. Use only if clearly needed and no safer alternative.
Do not use in pregnancy. No dosing adjustment recommendations exist as the drug is contraindicated. Pharmacokinetic changes in pregnancy (e.g., increased volume of distribution, altered metabolism) are not applicable.
Not applicable; Supr ENza is contraindicated in pregnancy. No dose adjustments are recommended as use is avoided entirely.
DELCOBESE is a novel synthetic cannabinoid receptor antagonist/inverse agonist (CB1R) approved for weight management. Monitor for psychiatric adverse effects (depression, suicidal ideation) especially during first 3 months. Avoid in patients with history of seizures due to lowered seizure threshold. Titrate dose slowly: start at 5 mg BID, increase to 10 mg BID after 4 weeks if tolerated. Discontinue if no 5% weight loss at 12 weeks. Use contraception in women of childbearing potential due to teratogenicity. Check liver function tests monthly for first 6 months due to rare hepatotoxicity.
SUPRENZA (buprenorphine/naloxone) sublingual film is used for opioid dependence. Monitor for respiratory depression especially when combined with benzodiazepines or alcohol. The naloxone component is poorly absorbed sublingually but precipitates withdrawal if injected. Administer only after clear signs of withdrawal to avoid precipitated withdrawal. Adjust dose in hepatic impairment as buprenorphine is hepatically metabolized.
