Study Notes
- Benztropine (Cogentin) is a prototype drug used to manage symptoms of unrest and digest issues, including severe dry mouth, liver disease, and urinary problems.
- Contraindications for Benztropine include narrow-angle glaucoma, myasthenia gravis, blockage of the urinary tract, severe constipation, and enlarged prostate.
- Drug interactions with Benztropine include aripiprazole, lorazepam, docusate, divalproex sodium, gabapentin, ziprasidone, haloperidol, clonazepam, lamotrigine, lisinoprol, lithium, metformin, fluoxetine, risperidone, quetiapine, levothyroxine, topiramate, trazodone, bupropion, sertraline, and olanzapine.
- Over-the-counter cold medicines should be avoided, as they can enhance dopamine release or activate dopamine receptors, producing additive effects.
- Haloperidol decreases the effectiveness of benztropine, and benztropine should not be taken with alcohol due to combined sedative effects.
- Lab tests, herbal, and food information regarding the use of Benztropine are unknown.
- Treatment for Benztropine overdose includes the use of physostigmine, a cholinesterase inhibitor, to reverse symptoms of anticholinergic intoxication.
- Alzheimer's disease is the second most common degenerative disease of the central nervous system, characterized by memory loss, confusion, dementia, and progressive brain function loss.
- Alzheimer's disease causes include genetic factors, chronic inflammation, excess free radicals, environmental factors, immunologic factors, nutritional factors, viruses, and structural damage in the brain.
- Symptoms of Alzheimer's disease include confusion and disorientation, impaired memory and judgement, inability to recognize family and friends, aggressiveness, depression, psychoses, and anxiety.
- Pharmacotherapy goals for Alzheimer's disease include slowing memory loss, managing dementia symptoms, improving activities of daily living, and improving behavior and cognition.
- Cholinesterase inhibitors, such as donepezil (Aricept), are used to manage Alzheimer's disease by preventing the breakdown of acetylcholine and enhancing its transmission in neurons.
- Donepezil (Aricept) is an Alzheimer's disease drug and cholinesterase inhibitor that improves memory by enhancing the effects of acetylcholine in neurons and is most effective when given on a regular schedule.
- Adverse effects of donepezil include nausea/vomiting, dizziness, headache, abnormal dreams, irritability, and darkened urine.
- Donepezil is most effective in the early stages of Alzheimer's disease and has modest efficacy in later stages.
- Cholinesterase inhibitors work by preventing the breakdown of acetylcholine and enhancing its transmission in cholinergic neurons, slowing the progression of Alzheimer's disease.
- Examples of cholinesterase inhibitors include donepezil, galantamine (Razadyne, Reminyl), and rivastigmine (Exelon).
