Anticholinergicsare drugs used to treat involuntary muscle movements.

Other times, they are a side effect ofpsychiatric medications.

In the 19th century, anticholinergic agents were introduced intomedications for Parkinsons disease.

As other more effective drugs have been developed, the use of anticholinergics to treat Parkinsons has declined.

This is largely due to the more severe side effects that these medications can have on older people.

How Anticholinergics Work

Anticholinergics work by blocking the action ofa chemical messenger called acetylcholine.

One of the most common uses of anticholinergics is as a treatment for asthma.

These medications help ease asthma symptoms by relaxing and enlarging the airway, which makes breathing easier.

These anticholinergics generally cannot be bought over the counter; they can only be prescribed by a physician.

The anticholinergic a healthcare provider might prescribe depends on the condition that is being treated.

Drugs With Anticholinergic Effects

Some prescription and over-the-counter medications also have anticholinergic properties.

Side Effects of Anticholinergics

People taking anticholinergics can experience side effects.

This is known as anticholinergic syndrome, poisoning, or toxicity and requires immediate medical attention.

Long-Term Side Effects

Some research suggests that long-term use of anticholinergics may contribute to cognitive decline.

Long-term use of anticholinergics is also not recommended forpeople with schizophrenia.

Precautions for Anticholinergics

Certain precautions need to be taken when using anticholinergics.
