Disease interactions
22 potential interactions Applies to: 17 conditions, including Depression, Myasthenia Gravis, Dementia, Urinary Retention, and Drug Dependence.
Acute Alcohol Intoxication
Major:
ethchlorvynol
Ethchlorvynol has a major potential interaction with Acute Alcohol Intoxication.
Anxiolytic, sedative, and hypnotic agents should generally not be given to patients with acute alcohol intoxication exhibiting depressed vital signs. The central nervous system depressant effects of these agents may be additive with those of alcohol. Severe respiratory depression and death may occur. Therapy with such agents should be administered cautiously in patients who might be prone to acute alcohol intake.
Alcoholism
Major:
ethchlorvynol
Ethchlorvynol has a major potential interaction with Alcoholism.
Anxiolytic, sedative, and hypnotic agents have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop, particularly after prolonged use of excessive dosages, and abrupt cessation and/or a reduction in dosage may precipitate withdrawal symptoms. In patients who have developed tolerance, overdosage can still produce respiratory depression and death. Therapy with anxiolytic, sedative, and hypnotic agents should be administered cautiously and for as brief a period as possible. Addiction-prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance or medical supervision when treated with these agents. In addition, it may be prudent to refrain from dispensing large quantities of medication to such patients. After prolonged use or if dependency is suspected, withdrawal of medication should be undertaken gradually using a dosage-tapering schedule.
Asphyxia
Moderate:
ethchlorvynol
Ethchlorvynol has a moderate potential interaction with Asphyxia.
Oral anxiolytic, sedative, and hypnotic agents may cause respiratory depression and apnea when given in high dosages or following acute overdose. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders. Therapy with anxiolytic, sedative, and hypnotic agents should be administered cautiously in these patients. Appropriate monitoring and individualization of dosage are recommended.
Central Nervous System Disorders
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Central Nervous System Disorders.
Tolterodine is associated with anticholinergic central nervous system (CNS) effects. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. Tolterodine should be used with caution in patients with Parkinson's disease and in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms.
Dementia
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Dementia.
Tolterodine is associated with anticholinergic central nervous system (CNS) effects. If a patient experiences anticholinergic CNS effects, dose reduction or drug discontinuation should be considered. Tolterodine should be used with caution in patients with Parkinson's disease and in patients with preexisting dementia treated with cholinesterase inhibitors due to the risk of aggravation of symptoms.
Depression
Major:
ethchlorvynol
Ethchlorvynol has a major potential interaction with Depression.
A variety of abnormal thinking and behavior changes have been reported to occur in association with the use of most anxiolytics, sedatives and hypnotics. Some of these changes include decreased inhibition, aggressiveness, agitation, and hallucinations. These drugs can cause or exacerbate mental depression and cause suicidal behavior and ideation. Therapy with these drugs should be administered cautiously in patients with a history of depression or other psychiatric disorders. Patients should be monitored for any changes in mood or behavior. It may be prudent to refrain from dispensing large quantities of medication to these patients.
Drug Dependence
Major:
ethchlorvynol
Ethchlorvynol has a major potential interaction with Drug Dependence.
Anxiolytic, sedative, and hypnotic agents have the potential to cause dependence and abuse. Tolerance as well as physical and psychological dependence can develop, particularly after prolonged use of excessive dosages, and abrupt cessation and/or a reduction in dosage may precipitate withdrawal symptoms. In patients who have developed tolerance, overdosage can still produce respiratory depression and death. Therapy with anxiolytic, sedative, and hypnotic agents should be administered cautiously and for as brief a period as possible. Addiction-prone individuals, such as those with a history of alcohol or substance abuse, should be under careful surveillance or medical supervision when treated with these agents. In addition, it may be prudent to refrain from dispensing large quantities of medication to such patients. After prolonged use or if dependency is suspected, withdrawal of medication should be undertaken gradually using a dosage-tapering schedule.
Gastrointestinal Obstruction
Major:
tolterodine
Tolterodine has a major potential interaction with Gastrointestinal Obstruction.
The use of tolterodine is contraindicated in patients with GI obstruction, ileus, or obstructive uropathy. Tolterodine exerts anticholinergic activity by competitive antagonism of muscarinic receptors.
Glaucoma/Intraocular Hypertension
Major:
tolterodine
Tolterodine has a major potential interaction with Glaucoma/Intraocular Hypertension.
The use of tolterodine is contraindicated in patients with uncontrolled angle-closure (narrow angle) glaucoma. Tolterodine exerts anticholinergic activity and can result in increased intraocular pressure and loss of accommodation.
Moderate:
ethchlorvynol
Ethchlorvynol has a moderate potential interaction with Glaucoma/Intraocular Hypertension.
Some hypnotic drugs can have an anticholinergic effect and should be used with caution in patients with glaucoma, and trouble urinating due to retention or enlarged prostate.
Liver Disease
Major:
ethchlorvynol
Ethchlorvynol has a major potential interaction with Liver Disease.
Ethchlorvynol is thought to be metabolized by the liver and subsequently excreted in the urine, primarily as metabolites. Patients with renal and/or liver disease may be at greater risk for adverse effects from ethchlorvynol, including central nervous system and respiratory depression, due to decreased drug clearance. Therapy with ethchlorvynol should be administered cautiously in patients with impaired renal and/or hepatic function. In one study, patients with renal impairment experienced excessive drowsiness following repeated dosing of the drug, presumably due to its accumulation in the plasma.
Moderate:
ethchlorvynol
Ethchlorvynol has a moderate potential interaction with Liver Disease.
In general, anxiolytics, sedatives and hypnotics are extensively metabolized by the liver. Their plasma clearance may be decreased and their half-life prolonged in patients with impaired hepatic function. Therapy with these drugs should be administered cautiously in patients with liver disease (some are not recommended in severe liver impairment), and the dosage should be adjusted accordingly. Laboratory testing is recommended prior and during treatment.
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Liver Disease.
Tolterodine undergoes biotransformation in the liver of extensive metabolizers to an active metabolite. Poor metabolizers have a greater concentration of active parent and less active metabolite, however the net activity of tolterodine is expected to be the same. The pharmacokinetic disposition of tolterodine can be significantly altered in patients with hepatic dysfunction. Therapy with tolterodine should be administered cautiously in patients with severe hepatic impairment and dosage should be reduced to no greater than 1 mg twice daily.
Long QT Syndrome
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Long QT Syndrome.
Tolterodine has been associated with QT prolongation. The effect on QT interval correlates with plasma concentration of tolterodine. Caution is recommended when prescribing this agent to patients with a known history of QT prolongation or to patients who are taking Class IA (e.g., quinidine, procainamide) or Class III (e.g., amiodarone, sotalol) antiarrhythmic medications.
Myasthenia Gravis
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Myasthenia Gravis.
Tolterodine acts as a competitive antagonist of acetylcholine at postganglionic muscarinic receptors. Caution is recommended when using this agent in patients with myasthenia gravis, a disease characterized by decreased cholinergic activity at the neuromuscular junction.
Porphyria
Major:
ethchlorvynol
Ethchlorvynol has a major potential interaction with Porphyria.
The use of ethchlorvynol is contraindicated in patients with a history of porphyria. Ethchlorvynol has been reported to precipitate acute attacks of porphyria in susceptible patients.
Pulmonary Impairment
Moderate:
ethchlorvynol
Ethchlorvynol has a moderate potential interaction with Pulmonary Impairment.
Oral anxiolytic, sedative, and hypnotic agents may cause respiratory depression and apnea when given in high dosages or following acute overdose. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders. Therapy with anxiolytic, sedative, and hypnotic agents should be administered cautiously in these patients. Appropriate monitoring and individualization of dosage are recommended.
Renal Dysfunction
Major:
ethchlorvynol
Ethchlorvynol has a major potential interaction with Renal Dysfunction.
Ethchlorvynol is thought to be metabolized by the liver and subsequently excreted in the urine, primarily as metabolites. Patients with renal and/or liver disease may be at greater risk for adverse effects from ethchlorvynol, including central nervous system and respiratory depression, due to decreased drug clearance. Therapy with ethchlorvynol should be administered cautiously in patients with impaired renal and/or hepatic function. In one study, patients with renal impairment experienced excessive drowsiness following repeated dosing of the drug, presumably due to its accumulation in the plasma.
Moderate:
tolterodine
Tolterodine has a moderate potential interaction with Renal Dysfunction.
The renal elimination of tolterodine and active metabolite is limited and a prolonged half-life is not anticipated in patients with renal impairment. However, the pharmacokinetic disposition of tolterodine has not been evaluated in patients with renal impairment and it is recommended that tolterodine be administered cautiously in patients with compromised renal function.
Respiratory Arrest
Moderate:
ethchlorvynol
Ethchlorvynol has a moderate potential interaction with Respiratory Arrest.
Oral anxiolytic, sedative, and hypnotic agents may cause respiratory depression and apnea when given in high dosages or following acute overdose. However, some patients may be susceptible at commonly used dosages, including the elderly, debilitated or severely ill patients, those receiving other CNS depressants, and those with limited ventilatory reserve, chronic pulmonary insufficiency or other respiratory disorders. Therapy with anxiolytic, sedative, and hypnotic agents should be administered cautiously in these patients. Appropriate monitoring and individualization of dosage are recommended.
Urinary Retention
Major:
tolterodine
Tolterodine has a major potential interaction with Urinary Retention.
The use of tolterodine is contraindicated in patients with GI obstruction, ileus, or obstructive uropathy. Tolterodine exerts anticholinergic activity by competitive antagonism of muscarinic receptors.
Moderate:
