Amantadine in Parkinson's Disease: An Expert Opinion / Vinay Goyal
First Edition: 2022
Printed at:
Parkinson's disease is a common neurodegenerative disease affecting the elderly population. The disease remains a huge challenge and its prevalence is expected to double worldwide by 2040.
It is important to distinguish it from other neurodegenerative diseases; therefore, understanding its symptoms is important which can aid in better diagnosis as well as more specific management. The management of Parkinson's disease can often be challenging; hence, it is important to increase awareness of other therapeutic options. Levodopa is the mainstay in the pharmacological management of Parkinson's disease; however, the drug has been associated with some side effects. Additionally, it is important that treatment is individualized and tailored for individual patients based on their condition.
Amantadine has been in use since 1966; however, its use in Parkinson's disease initiated in 1968, when an old woman experienced a remarkable remission in her symptoms of rigidity, tremor, and akinesia. Since then, the drug has been utilized in the management of Parkinson's disease.
The book provides a comprehensive understanding on amantadine and its pharmacological and clinical efficacy.
