Benzgalantamine
/api/v1/drug/benzgalantamineMechanism of action
Sourced from openFDAAlthough the etiology of cognitive impairment in Alzheimer's disease (AD) is not fully understood, it has been reported that acetylcholine-producing neurons degenerate in the brains of patients with Alzheimer's disease. The degree of this cholinergic loss has been correlated with degree of cognitive impairment and density of amyloid plaques (a neuropathological hallmark of Alzheimer's disease).

( 2.1 ) Hepatic impairment: Should not exceed 10 mg twice daily for moderate hepatic impairment; use in patients with severe hepatic impairment is not recommended ( 2.2 ) Renal impairment: Should not exceed 10 mg twice daily for creatinine clearance 9 to 59 mL/min; use in patients with creatinine clearance less than 9 mL/min is not recommended. ( 2.3 ) 2.1 Recommended Dosage and Administration Dosage The recommended starting dosage is 5 mg twice a day (10 mg/day) by mouth. Increase to initial maintenance dosage of 10 mg twice daily (20 mg/day) after a minimum of 4 weeks, based on clinical response and tolerability. Dosage may be increased to the maximum recommended dosage of 15 mg twice a day (30 mg/day) after a minimum of 4 weeks at 10 mg twice daily. Administration ZUNVEYL can be taken with or without food. ZUNVEYL should not be taken with alcohol [see Clinical Pharmacology (12.3) ]. Swallow whole; do not split, crush or chew. Ensure adequate fluid intake during treatment.
Warnings & precautions
Sourced from openFDASerious skin reactions: Discontinue at first appearance of skin rash. ( 5.1 ) All patients should be considered at risk for adverse effects on cardiac conduction, including bradycardia and AV block, because of vagotonic effects on sinoatrial and atrioventricular nodes. ( 5.3 ) Active or occult gastrointestinal bleeding: Monitor, especially those with an increased risk for developing ulcers. ( 5.4 ) Cholinomimetics may cause bladder outflow obstruction. ( 5.5 ) Monitor for respiratory adverse events in patients with a history of severe asthma or obstructive pulmonary disease. ( 5.7 ) 5.1 Serious Skin Reactions Serious skin reactions (e.g., Stevens-Johnson syndrome and acute generalized exanthematous pustulosis) have been reported in patients receiving galantamine (the active metabolite of (ZUNVEYL) tablets. Inform patients and caregivers that the use of ZUNVEYL tablets should be discontinued at the first appearance of a skin rash, unless the rash is clearly not drug-related. If signs or symptoms suggest a serious skin reaction, use of this drug should not be resumed, and alternative therapy should be considered [see Contraindications (4) ]. 5.2 Anesthesia ZUNVEYL, as a cholinesterase inhibitor, is likely to increase the neuromuscular blocking effects of succinylcholine-type and similar neuromuscular blocking agents during anesthesia. 5.3 Cardiovascular Conditions Because of their pharmacological action, cholinesterase inhibitors, including ZUNVEYL, have vagotonic effects on the sinoatrial and atrioventricular nodes, leading to bradycardia and AV block.
Adverse reactions
Sourced from openFDAThe following serious adverse reactions are discussed in more detail elsewhere in the labeling: Serious Skin Reactions [see Warnings and Precautions (5.1) ] Cardiovascular Conditions [see Warnings and Precautions (5.3) ] Gastrointestinal Conditions [see Warnings and Precautions (5.4) ] Genitourinary Conditions [see Warnings and Precautions (5.5) ] Neurological Conditions [see Warnings and Precautions (5.6) ] Pulmonary Conditions [see Warnings and Precautions (5.7) ] The most common adverse reactions with galantamine tablets (≥5%) were nausea, vomiting, diarrhea, dizziness, headache, and decreased appetite. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Alpha Cognition Inc. at 1-877-257-4203 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The safety of ZUNVEYL has been established in studies of galantamine immediate-release tablets and galantamine extended-release capsules [see Clinical Studies (14) ] . Below is a display of the adverse reactions of galantamine in these studies.
Use in specific populations
Sourced from openFDAPregnancy: Based on animal data may cause fetal harm. ( 8.1 ) 8.1 Pregnancy Risk Summary There are no adequate data on the developmental risk associated with the use of ZUNVEYL or galantamine in pregnant women. In studies conducted in animals, administration of galantamine during pregnancy resulted in developmental toxicity (increased incidence of morphological abnormalities and decreased growth in offspring) at doses similar to or greater than those used clinically (see Data ). In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively. The background risk of major birth defects and miscarriage for the indicated population is unknown. Data Animal Data In rats, administration of galantamine (oral doses of 2, 8, or 16 mg/kg/day), from day 14 (females) or day 60 (males) prior to mating and continuing in females through the period of organogenesis, resulted in an increased incidence of fetal skeletal variations at the two highest doses, which were associated with maternal toxicity. The no-effect dose for embryo-fetal developmental toxicity in rats (2 mg/kg/day) is approximately equal to the maximum recommended human dose (MRHD) of 22 mg/day galantamine (equivalent to 30 mg/day benzgalantamine) on a body surface area (mg/m 2 ) basis.
Pharmacokinetics
Sourced from openFDA- Metabolism
- Benzgalantamine is a prodrug of galantamine, the active metabolite. The systemic exposures of benzgalantamine are less than 1% of galantamine exposures; therefore, the pharmacokinetic information presented below is for that of galantamine.
Overdosage
Sourced from openFDABecause strategies for the management of overdose are continually evolving, it is advisable to contact a poison control center to determine the latest recommendations for the management of an overdose of any drug. As in any case of overdose, general supportive measures should be utilized. Signs and symptoms of significant overdosing of galantamine are predicted to be similar to those of overdosing of other cholinomimetics. These effects generally involve the central nervous system, the parasympathetic nervous system, and the neuromuscular junction. In addition to muscle weakness or fasciculations, some or all of the following signs of cholinergic crisis may develop: severe nausea, vomiting, gastrointestinal cramping, salivation, lacrimation, urination, defecation, sweating, bradycardia, hypotension, respiratory depression, collapse and convulsions. Increasing muscle weakness is a possibility and may result in death if respiratory muscles are involved. Tertiary anticholinergics such as atropine may be used as an antidote for ZUNVEYL overdosage.
