Inhibits P2Y12 platelet receptor, blocking ADP-mediated platelet aggregation.
Ig G1κ monoclonal antibody that binds to the neonatal Fc receptor (Fc Rn), reducing Fc Rn-mediated recycling of Ig G, thereby lowering circulating Ig G levels including pathogenic Ig G autoantibodies.
Reduction of thrombotic cardiovascular events in patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI),Off-label: Prevention of stent thrombosis in high-risk PCI patients
FDA: Treatment of generalized myasthenia gravis (g MG) in adult patients who are anti-acetylcholine receptor (ACh R) antibody positive.,Off-label: Not indicated for other conditions.
1 drop of 0.45% solution in each eye once daily in the evening or as directed by physician.
Initial dose 2 mg subcutaneously twice daily; after 3 months, increase to 4 mg subcutaneously twice daily based on clinical response and tolerability.
Terminal elimination half-life: approximately 2-3 hours in aqueous humor; systemic half-life is negligible due to low plasma concentrations.
Terminal elimination half-life: 64-104 hours (mean 84 hours). Clinical context: Supports once-daily dosing; steady-state achieved in ~2-3 weeks.
Prodrug; metabolized to active metabolite primarily via CYP2C19, with contributions from CYP3A4, CYP2C9, CYP2B6
Degraded by general proteolysis into small peptides and amino acids; not metabolized by cytochrome P450 enzymes.
Renal excretion of unchanged drug accounts for approximately 1-2% of an administered dose; the remainder is metabolized in ocular tissues and eliminated via nasolacrimal drainage and gastrointestinal tract, with minimal systemic absorption. Biliary/fecal excretion is negligible.
Biliary/fecal (55-65% as parent drug and metabolites); renal (30-40%, primarily as conjugated metabolites, <3% unchanged).
Approximately 60-70% bound to plasma proteins, primarily albumin.
>99% primarily to albumin.
Due to minimal systemic absorption, volume of distribution data is not clinically relevant; for the fraction absorbed, estimated Vd is approximately 0.2-0.4 L/kg.
Approximately 30 L/kg (0.43 L/kg in humans based on 70 kg). Extensive extravascular distribution, particularly to the liver (target organ via OATP1B1 uptake).
Ocular instillation: systemic bioavailability is low (<1%) due to extensive first-pass metabolism in the nasal mucosa and gastrointestinal tract after nasolacrimal drainage.
Oral: 20-30% (variable; low due to first-pass metabolism in gut wall and liver).
No specific renal dose adjustments recommended; use with caution in severe renal impairment (Cr Cl <30 m L/min) due to potential systemic accumulation.
No dose adjustment recommended for mild to moderate renal impairment. Not studied in severe renal impairment (e GFR <30 m L/min/1.73 m2) or end-stage renal disease; use not recommended.
No specific hepatic dose adjustments recommended; use with caution in severe hepatic impairment (Child-Pugh Class C) due to lack of data.
No dose adjustment required for mild to moderate hepatic impairment (Child-Pugh A or B). Not studied in severe hepatic impairment (Child-Pugh C); use not recommended.
Safety and effectiveness in pediatric patients have not been established; use is not recommended.
Not approved for use in pediatric patients. Safety and efficacy not established.
No specific dose adjustments in elderly; use same as adult dosing, with monitoring for ocular adverse effects.
No specific dose adjustment required based on age. Use caution due to potential for decreased renal function and increased sensitivity to adverse effects; monitor closely.
Efficacy depends on active metabolite formation; reduced efficacy in CYP2C19 poor metabolizers. Avoid use in patients with active pathological bleeding or history of transient ischemic attack/stroke.
WARNING: Increased risk of serious infections, including opportunistic infections. Due to its mechanism of reducing Ig G levels, BYSANTI may increase the risk of infections. Monitor for signs and symptoms of infection and withhold treatment if severe infection occurs.
Bleeding risk, especially in patients undergoing surgery; thrombotic thrombocytopenic purpura (TTP) reported; premature discontinuation increases cardiovascular event risk; CYP2C19 poor metabolizers may have reduced efficacy.
Serious infections: Increased risk of infections, including opportunistic infections. If severe infection occurs, withhold therapy.,Hypersensitivity reactions: Monitor for infusion-related reactions (e.g., pyrexia, headache, hypertension).,Immunizations: Avoid live or live-attenuated vaccines during treatment.,Fetal risk: May cause fetal harm based on animal studies; advise females of reproductive potential of potential risk.
Active pathological bleeding (e.g., peptic ulcer, intracranial hemorrhage); history of transient ischemic attack or stroke; severe hepatic impairment; hypersensitivity to AKPRO or any component.
Hypersensitivity to efgartigimod alfa or any excipients.
No known food interactions.
No specific food interactions are known with BYSANTI. However, grapefruit and other CYP3A4-modulating foods may affect co-administered medications, but not bimekizumab itself. Maintain a balanced diet as recommended for overall health.
Category C. First trimester: Based on animal studies, may cause fetal harm. No adequate human studies. Second and third trimesters: Risk of premature closure of ductus arteriosus and oligohydramnios with NSAID use after 20 weeks gestation.
No human data; animal studies insufficient. Based on mechanism (CGRP receptor antagonist), theoretical risk of fetal harm; avoid use in pregnancy, especially first trimester.
Excreted in breast milk in low amounts (M/P ratio not reported). Use with caution due to potential adverse effects on infant (e.g., gastrointestinal, renal). Short-term use is generally considered acceptable.
No human data; present in animal milk. M/P ratio unknown. Not recommended during breastfeeding.
No specific dose adjustment recommended for pregnancy; however, avoid use after 20 weeks gestation due to risks of premature ductus arteriosus closure and oligohydramnios. Use lowest effective dose for shortest duration.
No established dose adjustments; contraindicated in pregnancy due to potential risk.
AKPRO is a combination ophthalmic solution containing proparacaine 0.5% and fluorescein sodium 0.25%. Use only for diagnostic procedures; never dispense for patient self-administration due to risk of corneal toxicity with repeated use. Apply one drop per eye, then wait 1-2 minutes for maximal anesthesia. Blot excess to reduce systemic absorption. Monitor for corneal epithelial defects after use.
BYSANTI (bimekizumab) is a humanized monoclonal Ig G1 antibody that inhibits both IL-17A and IL-17F. For plaque psoriasis, the recommended dose is 320 mg (two subcutaneous injections) at weeks 0, 4, 8, 12, and then every 8 weeks. Assess for tuberculosis prior to initiation; latent TB must be treated before starting therapy. Monitor for new onset or exacerbation of inflammatory bowel disease; discontinue if symptoms occur. Can be used with or without methotrexate for psoriatic arthritis. Live vaccines are contraindicated during treatment.
Do not rub your eyes after the drops are applied, as the anesthetic may mask injury.,This medication is for use in a doctor's office only; do not take it home.,Temporary blurred vision and stinging may occur immediately after the drop.,Avoid driving or operating machinery until vision clears completely.,Inform your doctor if you have a history of corneal disease, glaucoma, or allergies to anesthetics.
BYSANTI is given as two injections under the skin, typically in the abdomen or thigh.,Tell your doctor if you have had tuberculosis or have been in close contact with someone with TB.,Do not receive live vaccines during treatment; non-live vaccines are acceptable.,Seek medical attention if you develop new or worsening stomach pain, diarrhea, or bloody stools.,Report any signs of infection (fever, chills, cough) as BYSANTI increases infection risk.
