Adalimumab is a recombinant human Ig G1 monoclonal antibody that binds specifically to tumor necrosis factor alpha (TNFα) and neutralizes its biological activity by blocking its interaction with p55 and p75 cell surface TNF receptors. It also modulates biological responses induced or regulated by TNFα, including changes in adhesion molecules, chemotaxis, and apoptosis.
Selective antagonist of alpha-1 adrenergic receptors, causing relaxation of smooth muscle in blood vessels and prostate.

80 mg subcutaneously every other week. For patients weighing ≥100 kg, 80 mg every week.
Initial: 1 mg orally once daily, titrated based on standing blood pressure response up to 16 mg daily as a single dose or divided twice daily. Maximum: 16 mg/day.
Terminal elimination half-life approximately 10–14 days in adults, supporting every-other-week dosing; may be shorter in pediatric patients.
Terminal elimination half-life is approximately 22 hours, allowing once-daily dosing; peak effect on blood pressure occurs at 2-6 hours post-dose.
Adalimumab is a monoclonal antibody that is metabolized via catabolism into peptides and amino acids. CYP450 enzymes are not involved. No active metabolites.
Extensively metabolized in the liver via O-demethylation and hydroxylation; CYP3A4 is the major enzyme involved.
Primarily degraded into amino acids and recycled or excreted in urine (less than 1% unchanged); no significant biliary/fecal elimination.
Primarily hepatic metabolism (approx. 60-70%) with biliary excretion of metabolites; renal excretion accounts for about 30-40% of the dose, mainly as metabolites with <5% unchanged drug.
Approximately 95% bound to serum proteins, primarily alpha-1-acid glycoprotein and albumin.
98-99% bound to plasma proteins (primarily albumin).
Approximately 4.7–6.0 L/kg, indicating extensive distribution into tissues consistent with a monoclonal antibody.
0.5-1.0 L/kg (approximately 50-70 L in adults); indicates extensive extravascular distribution.
Subcutaneous: approximately 64% (range 50–80%) absolute bioavailability relative to intravenous administration.
Oral bioavailability is approximately 65% (range 43-81%) with minimal first-pass effect.
No dose adjustment required for mild to moderate renal impairment (Cr Cl ≥30 m L/min). Not studied in severe renal impairment (Cr Cl <30 m L/min) or ESRD; use with caution.
No dose adjustment required for GFR ≥30 m L/min. For GFR <30 m L/min, start with 0.5 mg daily and titrate cautiously due to increased sensitivity.
No formal studies in hepatic impairment. Use with caution in moderate to severe impairment (Child-Pugh B or C) due to limited data.
Child-Pugh A: Start at 0.5 mg daily. Child-Pugh B or C: Contraindicated due to extensive hepatic metabolism.
Approved for pediatric plaque psoriasis (≥12 years): 80 mg subcutaneously every other week. For pediatric psoriatic arthritis (≥12 years): 80 mg subcutaneously every other week. For pediatric hidradenitis suppurativa (≥12 years, ≥60 kg): 160 mg on day 1, then 80 mg every other week. Pediatric Crohn's disease (≥6 years, ≥40 kg): 160 mg on day 1, then 80 mg on day 15, then 80 mg every other week; for <40 kg: 80 mg on day 1, then 40 mg on day 15, then 40 mg every other week.
Safety and efficacy not established in pediatric patients; use not recommended.
No specific dose adjustment required; but monitor for infections in patients ≥65 years due to increased risk.
Initiate at 0.5 mg daily due to increased risk of orthostatic hypotension. Titrate slowly based on tolerability and response.
WARNING: SERIOUS INFECTIONS and MALIGNANCY. SERIOUS INFECTIONS: Patients treated with adalimumab are at increased risk for serious infections leading to hospitalization or death, including tuberculosis (TB), bacterial sepsis, invasive fungal infections (such as histoplasmosis), and infections due to other opportunistic pathogens. Discontinue adalimumab if a serious infection develops. MALIGNANCY: Lymphoma and other malignancies, some fatal, have been reported in children and adolescent patients treated with TNF blockers including adalimumab.

Known hypersensitivity to adalimumab or any inactive component of the product,Active serious infections including sepsis, tuberculosis, and opportunistic infections
Hypersensitivity to doxazosin or other quinazolines
No significant food interactions. Grapefruit and other CYP450 modulators do not affect adalimumab. Take without regard to meals.
Avoid grapefruit and grapefruit juice as they may increase doxazosin levels. Take with food to reduce gastrointestinal upset. No other significant food interactions.
Abrilada (adalimumab-adbm) is a TNF-alpha inhibitor. Limited human data; animal studies show no evidence of teratogenicity. Potential risk of increased infection in neonates exposed in utero. First trimester: Minimal known risk. Second/third trimester: May cross placenta; theoretical risk of immunosuppression.
Pregnancy Category C. First trimester: No evidence of teratogenicity in animal studies; limited human data. Second/third trimesters: Potential risk of fetal hypotension and hypoxia from maternal hypotension. Avoid use in pregnancy unless benefit outweighs risk.
Excreted in human milk in low concentrations; M/P ratio not well defined. Considered compatible with breastfeeding, but monitor infant for infection risks.
Excreted in human milk; M/P ratio unknown. Caution due to potential for hypotension in nursing infants. Use only if essential.
No dose adjustment routinely required; pregnancy may increase clearance, but no established guidelines for dose modification.
No established dose adjustments for pregnancy; use lowest effective dose due to potential for increased clearance and changes in volume of distribution.
ABRILADA (adalimumab) is a TNF-alpha inhibitor. Monitor for latent TB reactivation with PPD or IGRA before initiation. Injection site reactions are common; rotate sites and apply cold compresses. Avoid live vaccines during therapy. Assess for new-onset or worsening heart failure, demyelinating disorders, and cytopenias. Increased risk of serious infections; screen for HBV, HCV, and fungal infections. Consider temporarily holding therapy for major surgical procedures.
CARDURA (doxazosin) is an alpha-1 blocker used for hypertension and benign prostatic hyperplasia (BPH). First-dose syncope is more common with immediate-release (IR) than extended-release (GITS). Start IR at 1 mg at bedtime and titrate slowly. GITS formulation minimizes orthostatic effects. Monitor blood pressure carefully in elderly patients. May cause intraoperative floppy iris syndrome (IFIS) during cataract surgery; do not stop therapy preoperatively. Avoid use in patients with orthostatic hypotension or micturition syncope.
Inspect injection site for redness, swelling, or itching; apply cold compress if needed.,Report signs of infection: fever, cough, painful urination, or skin wounds.,Avoid live vaccines (e.g., MMR, shingles, nasal flu) during treatment.,Review all current medications, including OTC and herbal supplements.,Notify healthcare provider before any planned surgery.,Use reliable contraception if of childbearing potential; continue 5 months after stopping.,Report new or worsening symptoms: shortness of breath, chest pain, numbness, vision changes.,Store ABRILADA in the refrigerator (36°F-46°F); do not freeze or shake.
Take the first dose at bedtime to minimize dizziness. Sit or lie down if you feel lightheaded.,Avoid sudden position changes; rise slowly from sitting or lying positions.,May cause dizziness, drowsiness, or blurred vision. Do not drive until you know how CARDURA affects you.,For BPH, it may take up to 2 weeks to improve symptoms. Do not stop medication abruptly.,Inform your surgeon if you are scheduled for cataract surgery; CARDURA may affect eye surgery outcomes.,Avoid alcohol, which can worsen side effects like dizziness and low blood pressure.,For hypertension, continue regular monitoring with your healthcare provider.
