Nootropics are drugs, supplements, or other substances that improve cognitive function. This includes memory, creativity, focus, and motivation. Cholinergics are a type of nootropic that work by increasing levels of acetylcholine in the brain. This neurotransmitter is involved in many aspects of cognition, including learning and memory. There are several different cholinergic drugs and supplements available, each with their own unique set of benefits and drawbacks. Understanding how cholinergics work and what they can offer is an important step in choosing the right one for you.

Are cholinergenics safe?

Cholinergenics are a type of drug that stimulates the release of acetylcholine. Acetylcholine is a neurotransmitter that is responsible for transmitting signals between nerves and muscles.
There are several types of cholinergenic drugs, and they are used to treat a variety of conditions such as Alzheimer’s disease, dementia, and even asthma. While these drugs can be effective in treating certain medical conditions, they can also be dangerous if not taken under the supervision of a doctor.
Some common side effects of cholinergenic drugs include confusion, agitation, hallucinations, and seizures. So it’s important to talk to your doctor before taking any cholinergenic drug to make sure it is safe for you.

History of Cholinergics


Cholinergics were discovered in the 1800s when scientists were looking for ways to treat digestive problems.

At the time, they didn’t know that cholinergics would eventually be used to treat a wide range of conditions such as dementia, heart failure, and chronic obstructive pulmonary disease (COPD). But over time, scientists learned that these drugs have a number of important health benefits.

Today, cholinergics are considered some of the most important drugs for treating neurodegenerative diseases like Alzheimer’s and Parkinson’s. And researchers are still working to find new ways to use these drugs to improve people’s health and quality of life.

Effects of Cholinergics

Cholinergics are a type of drug that work by increasing levels of the neurotransmitter acetylcholine in the brain. Acetylcholine is involved in many functions including memory, learning, muscle control, and wakefulness.

Acetylcholine is a neurotransmitter that is responsible for transmitting messages between nerves and muscles. It helps to regulate the activity of the muscles and plays a role in learning and memory.

Acetylcholine levels tend to decrease with age, which may be one reason why cognitive function diminishes as we get older. Some evidence suggests that increasing acetylcholine levels may help to improve cognitive function. There are a number of supplements available that claim to increase acetylcholine levels, but more research is needed to determine whether they are effective.

Cholinergics can be used to treat conditions such as Alzheimer’s disease, dementia, and even asthma. They are also used as wakefulness-promoting agents for people with sleep disorders. Some cholinergics, such as nicotine and caffeine, are also found naturally in foods and beverages.

Types of Cholinergics

The most popular types of cholinergics are those that stimulate the production of acetylcholine, which is a neurotransmitter that plays an important role in memory and muscle control. Some of the most common cholinergic drugs include:

  • Acetylcholine esterase inhibitors (e.g. Donepezil)
  • Muscarinic receptor agonists (e.g. Pilocarpine)
  • Nicotinic receptor agonists (e.g. Nicotine)


Donepezil is a drug that is used to treat the symptoms of Alzheimer’s disease. It works by blocking the action of an enzyme called acetylcholinesterase, which breaks down a chemical called acetylcholine. By blocking the action of this enzyme, Donepezil helps to keep levels of acetylcholine high, which helps to improve cognitive function and memory in people with Alzheimer’s disease.


Donepezil is a drug that is used to treat Alzheimer’s disease. It belongs to a class of drugs called cholinesterase inhibitors. These drugs work by preventing the breakdown of a chemical called acetylcholine. This chemical is important for the transmission of signals between nerve cells in the brain. Donepezil can improve symptoms such as memory problems and confusion in people with Alzheimer’s disease. It can also slow down the rate at which the condition progresses.

Side Effects:

The most common side effects of Donepezil are nausea, diarrhea, and vomiting. Other side effects include headache, dizziness, muscle cramps, and joint pain. Donepezil can also cause a person to feel tired or sleepy. It can make it difficult for a person to think clearly or move around easily. In some cases, Donepezil may cause a person to have an increased risk of falls.


Pilocarpine is a prescription drug used to treat dry mouth and glaucoma. It works by shrinking the tissues of the body that produce tears and sweat. This in turn increases the production of saliva and tears, which helps to improve dry mouth and relieve eye pressure.

Pilocarpine comes in both tablet and liquid form, and is typically taken three times per day. Some common side effects of this medication include blurred vision, headache, and nausea. It is important to speak with your doctor before taking Pilocarpine, as it may not be appropriate for everyone.


Pilocarpine is a medication used to treat dry mouth, a condition which is often caused by Sjögren’s syndrome.

Sjögren’s syndrome is an autoimmune disorder which can cause the body to produce insufficient amounts of tears and saliva. Symptoms of dry mouth include difficulty speaking, swallowing, and chewing, as well as a burning sensation in the throat and mouth. Pilocarpine works by increasing the production of saliva. It can be taken in tablet or liquid form, and typically begins to work within 15 minutes.

Side Effects:

Pilocarpine is a prescription drug used to treat glaucoma and dry mouth. It can cause a number of side effects, including:

  • blurred vision,
  • nausea,
  • vomiting,
  • diarrhea,
  • tiredness,
  • dizziness, and
  • headache.

Pilocarpine can also interact with other drugs you may be taking, so be sure to tell your doctor about all the medications you’re taking before starting treatment with pilocarpine.


Nicotine is a potent parasympathomimetic alkaloid found in the nightshade family of plants (Solanaceae) and it is principally responsible for the addictive properties of tobacco products. When chewed, smoked, or ingested, nicotine binds to nicotinic acetylcholine receptors (nAChRs) in the brain and periphery, where it induces feelings of pleasure and relaxation.


It is a stimulant drug that acts as a receptor agonist on nicotinic acetylcholine receptors, causing them to open and allow ions to flow across the cell membrane. This increases the activity of the acetylcholine neurotransmitter which mediates nicotine’s cognitive and behavioral effects.

Nicotine has powerful reinforcing effects due to its ability to increase dopamine levels in the brain. It is for this reason that it is so addictive. Nicotinic receptors are also found in other parts of the body, including the autonomic nervous system, where they regulate heart rate and blood pressure

Side Effects:

Nicotine is a stimulant that can have a number of side effects, including increased heart rate and blood pressure, headache, dizziness, nausea, and vomiting. It can also be addictive and lead to tobacco dependence.
