Cholinergics: synergistic effects

Cimetidine, erythromycin, ketoconazole, paroxetine: increased galantamine bioavailability

Patient monitoring

• Assess fluid intake and output to ensure adequate hydration, which helps reduce GI upset.

• Monitor cognitive status.

• Evaluate patient for cardiac conduction abnormalities. Assess pulse regularly for bradycardia.

• Observe for bleeding tendencies.

Assess for depression and suicidal ideation.

Patient teaching

• Instruct caregiver in proper technique for using oral pipette.

Galantamine (Reminyl): Used for more severe forms of dementia, the side-effect profile is similar as above.
These drugs include donepezil (Aricept), rivastigmine (Exelon), galantamine (Reminyl or Razadyne), and memantine (Namenda).
Next year, Maciw noted, an even larger number of key products, including Nexium, Diovan/ HCT, Avapro, Atacand, Singulair, Avalide, Nasonex, Avandia, Reminyl ER, Taxatore, Strattera, and Zomig/R will all come off patent, representing some $2.3 billion in sales.
(263) IHS GLOBAL INSIGHT, NICE Recommends Alzheimer's Drugs Aricept, Reminyl, Exelon, and Ebixa Following Review (2010), http://www.ihsglobalinsight.corn/SDA/SDADetail19338.htm (last visited Apr.
In March this year, the National Institute for Health and Clinical Excellence (Nice) issued new guidance recommending that people with Alzheimer's in the mild to moderate stages of the disease should be given treatment with Aricept (donepezil), Reminyl (galantamine) or Exelon (rivastigmine).
Some Welsh sheep farmers, who no longer feel that hill farming has a commercial or viable future, have now turned their hand to growing daffodils as an alternative source of the drug as generic manufacturers seek to develop and market an off-patent version of Reminyl. The market is currently worth approximately $8 billion and the occurrence of Alzheimer's is increasing at an alarming rate.
said it has begun sales in Japan of Reminyl, a drug for the treatment of patients with Alzheimer's-type dementia, supplied by Janssen Pharmaceutical K.K.
On 7 October 2010, NICE issued draft guidance, subject to appeal, recommending that Aricept (donepezil, manufactured by Eisai), Reminyl (galantamine, manufactured by Shire) and Exelon (rivastigmine, manufactured by Novartis) be made available to patients with early to moderate stage Alzheimer's disease.
Nice confirmed that it was extending previous recommendations for the use of three drugs - Donepezil (Aricept, Eisai/Pfizer), galantamine (Reminyl, Shire) and rivastigmine (Exelon, Novartis) - to include mild, as well as moderate Alzheimer's disease.
The National Institute for Health and Clinical Excellence had banned Aricept (donepezil), Reminyl (galantamine) and Exelon (rivastigmine).
Nice published new draft guidance saying that Aricept (donepezil), Reminyl (galantamine) and Exelon (rivastigmine) should be made available to people with mild as well as moderate disease -potentially benefiting thousands of people.
The draft decision is for three drugs, Aricept, Exelon and Reminyl.
