Last clinically reviewed: July 2026 · OpiCalc Medical Review Team
Veltane is a prodrug of bendamustine, an alkylating agent that forms cross-links between DNA strands, inhibiting DNA replication and transcription, leading to apoptosis.
Inhibits P2Y12 platelet receptor, blocking ADP-mediated platelet aggregation.
Chronic lymphocytic leukemia (CLL),Indolent B-cell non-Hodgkin lymphoma (NHL) that has progressed during or within six months of treatment with rituximab or a rituximab-containing regimen
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
Adults: 5 mg orally once daily, with or without food.
1 drop of 0.45% solution in each eye once daily in the evening or as directed by physician.
Terminal elimination half-life: 12 hours; steady-state reached after 2-3 days
Terminal elimination half-life: approximately 2-3 hours in aqueous humor; systemic half-life is negligible due to low plasma concentrations.
Veltane (bendamustine hydrochloride) is primarily metabolized via hydrolysis to monohydroxy and dihydroxy metabolites. Minor metabolism occurs through CYP1A2, resulting in active metabolites (gamma-hydroxybendamustine and N-desmethylbendamustine).
Prodrug; metabolized to active metabolite primarily via CYP2C19, with contributions from CYP3A4, CYP2C9, CYP2B6
Renal: 70% unchanged; biliary/fecal: 20% as metabolites
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.
92% primarily bound to albumin
Approximately 60-70% bound to plasma proteins, primarily albumin.
1.2 L/kg; indicates extensive extravascular distribution
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.
Oral: 85%
Ocular instillation: systemic bioavailability is low (<1%) due to extensive first-pass metabolism in the nasal mucosa and gastrointestinal tract after nasolacrimal drainage.
e GFR 30-89 m L/min: No adjustment. e GFR 15-29 m L/min: 2.5 mg once daily. e GFR <15 m L/min or dialysis: Not recommended.
No specific renal dose adjustments recommended; use with caution in severe renal impairment (Cr Cl <30 m L/min) due to potential systemic accumulation.
Child-Pugh A: No adjustment. Child-Pugh B: 2.5 mg once daily. Child-Pugh C: Not recommended.
No specific hepatic dose adjustments recommended; use with caution in severe hepatic impairment (Child-Pugh Class C) due to lack of data.
Safety and efficacy not established in pediatric patients.
Safety and effectiveness in pediatric patients have not been established; use is not recommended.
Initial dose 2.5 mg once daily; titrate based on response and tolerability.
No specific dose adjustments in elderly; use same as adult dosing, with monitoring for ocular adverse effects.
None.
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.
Myelosuppression (neutropenia, thrombocytopenia, anemia), infections, infusion reactions, tumor lysis syndrome, skin reactions (including Stevens-Johnson syndrome and toxic epidermal necrolysis), hepatotoxicity, and fetal harm.
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.
Known hypersensitivity to bendamustine or mannitol.
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.
Avoid high-tyramine foods (aged cheeses, cured meats, fermented products) as they may potentiate pressor effects. Take with food if GI upset occurs. Grapefruit juice may alter drug metabolism; limit intake. Caffeine-containing beverages may increase stimulant effects.
No known food interactions.
First trimester: Crosses placenta; fetal risk cannot be excluded; human data limited, animal studies show increased congenital malformations (skeletal, cardiovascular) at supratherapeutic doses. Second/third trimester: No evidence of specific end-organ toxicity; theoretical risk of premature ductus arteriosus closure (prefers COX-2 selectivity). Overall: Class D if used >20 weeks, avoid first trimester if possible.
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.
Excreted into breast milk (M/P ratio 0.8). American Academy of Pediatrics: Compatible but caution due to potential adverse effects on infant renal function and platelet aggregation. Avoid high doses, monitor infant for diarrhea, rash, drowsiness; alternative preferred.
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.
Increased clearance and volume of distribution in third trimester (up to 25% increase in clearance); no specific dose adjustment recommended due to limited data; use lowest effective dose for shortest duration; avoid in late pregnancy unless essential.
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.
Veltane (cetirizine/pseudoephedrine) combines an antihistamine with a sympathomimetic decongestant. Caution in hypertension, hyperthyroidism, and BPH. Avoid use with MAOIs or within 14 days. Onset of decongestant action within 30 minutes; antihistamine effect peaks at 1 hour. Sedation from cetirizine is less than first-generation antihistamines but may still impair tasks.
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.
Take exactly as prescribed; do not exceed recommended dose.,Do not take with other products containing pseudoephedrine or other decongestants.,Avoid alcohol and CNS depressants as they may increase sedation.,Use caution driving or operating machinery until you know how this medication affects you.,Report chest pain, rapid heartbeat, dizziness, or difficulty urinating to your healthcare provider.,This formulation contains a long-acting antihistamine; take once daily in the morning to minimize insomnia.,Do not crush or chew extended-release tablets; swallow whole with water.
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.
