HOW DO ANTICHOLINERGIC ANTIPARKINSON AGENTS WORK?

Anticholinergic antiparkinson agents are a class of medications used to treat the symptoms of Parkinson’s disease

The direct cause of Parkinson's disease or Parkinsonian-like syndrome is the deficiency of the neurotransmitter dopamine in the brain. Antiparkinson medicines aim to prolong the action of dopamine in the brain by:

  • Replacing dopamine
  • Inhibiting dopamine breakdown
  • Sensitizing dopamine receptors to stimulate dopamine release

Anticholinergic antiparkinson agents prolong dopamine action in the brain by inhibiting the reabsorption and storage of neurotransmitters. Reabsorption is a normal mechanism by which the body controls how long a nerve signal lasts. However, reabsorption can be an issue when there is a low level of dopamine. Hence, by limiting the reuptake of dopamine, anticholinergics increase dopamine concentration in the brain.
