Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists01:30

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists

671
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

Drugs Affecting Neurotransmitter Synthesis01:29

Drugs Affecting Neurotransmitter Synthesis

2.3K
Drugs affecting neurotransmitter synthesis can impact the adrenergic neuron and the synthesis of neurotransmitters. For example, α-methyltyrosine and carbidopa target specific enzymes involved in catecholamine synthesis. α-methyltyrosine inhibits the enzyme tyrosine hydroxylase, which converts tyrosine into dopamine. By blocking this enzyme, α-methyltyrosine reduces dopamine production and other catecholamines. Carbidopa, on the other hand, inhibits the enzyme dopa decarboxylase,...

Drugs Affecting Neurotransmitter Release or Uptake01:21

Drugs Affecting Neurotransmitter Release or Uptake

1.6K
Certain drugs can affect how neurotransmitters called catecholamines, are released or taken back up in the adrenergic neuron. They can have different effects on the body's sympathetic transmission. Reserpine, a natural compound found in the Rauwolfia shrub, blocks a transporter called vesicular monoamine transporter (VMAT), which leads to a buildup of catecholamines in the cell and reduces sympathetic transmission. Another drug called guanethidine works in multiple ways, including blocking...

Drug Delivery: Parenteral Route01:29

Drug Delivery: Parenteral Route

1.9K
The parenteral route is a critical method of drug administration. It delivers compounds directly into the systemic circulation and bypasses the gastrointestinal tract. This approach is particularly advantageous for drugs that exhibit poor absorption or instability when administered orally.
There are three primary parenteral routes: intravenous (IV), intramuscular (IM), and subcutaneous (SC). The IV route introduces the drug directly into the bloodstream, ensuring immediate action. The IM route...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

942
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

Area of Science:

  • Neuroscience
  • Pharmacology

Background:

  • Human desire for enhanced physical and cognitive abilities (concentration, vigilance, memory).
  • Pharmacological neuroenhancement defined as using legal, non-prescription psychoactive substances for cognitive improvement.
  • Caffeine identified as a common natural stimulant.

Purpose of the Study:

  • To differentiate between pharmacological neuroenhancement and brain doping.
  • To identify substances with proven cognitive enhancement effects in healthy subjects.

Main Methods:

  • Review of existing literature on psychoactive substances and cognitive function.
  • Analysis of studies investigating the effects of various drugs (stimulants, anti-dementia, anti-depressants) on healthy individuals.

Main Results:

  • Amphetamines, methylphenidate, and modafinil demonstrated significant positive effects on attentiveness, concentration, and alertness.
  • Other substances, including anti-dementia drugs and anti-depressants, did not show cognitive enhancement benefits in healthy subjects.

Conclusions:

  • Specific prescription drugs (amphetamines, methylphenidate, modafinil) can enhance cognitive functions like attention in healthy individuals.
  • The efficacy of many substances, including anti-dementia and anti-depressant medications, for cognitive enhancement in healthy populations is not supported by evidence.
