Galantamine Disease Interactions

There are 6 disease interactions with galantamine.

Major

Cholinesterase inhibitor (applies to galantamine) bradycardia

Major Potential Hazard, Moderate plausibility. Applicable conditions: Arrhythmias

Due to their pharmacological action, cholinesterase inhibitors can have a vagotonic effect on the sinoatrial and atrioventricular nodes producing bradycardia or heart block. Therapy with cholinesterase inhibitors should be administered cautiously in patients with preexisting bradycardia or underlying cardiac conduction abnormalities. Syncopal episodes have been reported. Atropine may be used to reverse bradycardia produced by cholinesterase inhibitors.

Major

Cholinesterase inhibitor (applies to galantamine) bronchospasm

Major Potential Hazard, Moderate plausibility. Applicable conditions: Chronic Obstructive Pulmonary Disease, Asthma

Cholinesterase inhibitors inhibit the hydrolysis of acetylcholine. The enhanced effect of acetylcholine produces constriction of the bronchi, increased bronchial secretions, and bronchospasm. Therapy with cholinesterase inhibitors should be administered cautiously in patients with respiratory dysfunction, history of asthma, or obstructive pulmonary disease. Respiratory function should be closely monitored for the occurrence of respiratory adverse reactions. Use of atropine along with discontinuation of the cholinesterase inhibitor may be required for serious respiratory distress.

Moderate

Cholinesterase inhibitor (applies to galantamine) PUD

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Peptic Ulcer

The use of cholinesterase inhibitors is associated with an increase in gastric acid secretion and gastric contractions. Monitor for symptoms of active or occult gastrointestinal bleeding, especially in patients at increased risk for developing ulcers (e.g., history of ulcer disease or concurrent use of nonsteroidal anti-inflammatory drugs).

Moderate

Cholinesterase inhibitor (applies to galantamine) seizures

Moderate Potential Hazard, Moderate plausibility.

Cholinesterase inhibitors have been associated with convulsions and tremor. Therapy with cholinesterase inhibitors should be administered cautiously in patients with seizure disorders. Patients with Alzheimer's disease should be closely monitored for seizures.

Moderate

Galantamine (applies to galantamine) hepatic impairment

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Liver Disease

In patients with moderate hepatic impairment (Child-Pugh score of 7 to 9), the dosage of galantamine or benzgalantamine should generally not exceed 16 mg/day or 20 mg/day, respectively. The use of galantamine or benzgalantamine in patients with severe hepatic impairment (Child-Pugh score of 10 to 15) is not recommended.

Moderate

Galantamine (applies to galantamine) renal impairment

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Renal Dysfunction

In patients with creatinine clearance of 9 to 59 mL/min, the dosage of galantamine or benzgalantamine should generally not exceed 16 mg/day or 20 mg/day, respectively. In patients with creatinine clearance less than 9 mL/min, the use of galantamine or benzgalantamine is not recommended.

Drug Interaction Classification

These classifications are only a guideline. The relevance of a particular drug interaction to a specific individual is difficult to determine. Always consult your healthcare provider before starting or stopping any medication.
Major Highly clinically significant. Avoid combinations; the risk of the interaction outweighs the benefit.
Moderate Moderately clinically significant. Usually avoid combinations; use it only under special circumstances.
Minor Minimally clinically significant. Minimize risk; assess risk and consider an alternative drug, take steps to circumvent the interaction risk and/or institute a monitoring plan.
Unknown No interaction information available.
