Depressants

493
Depressant drugs, including alcohol and sedative-hypnotics, diminish central nervous system activity by enhancing the action of gamma-aminobutyric acid (GABA), a neurotransmitter that reduces brain activity and promotes relaxation. These substances can have various therapeutic uses but also pose significant risks, especially when misused or combined.
Alcohol is a common depressant that can induce a sense of relaxation and reduced inhibition at low doses. Contrary to its occasional...

CNS Depressants: Alcohol and Nicotine

1.4K
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

Sedatives and Hypnotics: Overview01:23

Sedatives and Hypnotics: Overview

1.7K
Sedatives are drugs that alleviate anxiety, while hypnotics induce sleep. Both classes of medication suppress neuronal activity, leading to a calming effect for sedatives and facilitating sleep for hypnotics.
Sedative-hypnotics are categorized into barbiturates, benzodiazepines (BZDs), and non-benzodiazepines or Z-drugs. These drugs work by suppressing central nervous system activity, and this suppression is dose-dependent. Older sedative medications, like barbiturates, follow a linear curve in...

Sedatives and Hypnotics Drugs: Miscellaneous Agents

674
Sedatives and hypnotics encompass a wide range of substances, each with its unique mechanism of action, uses, and potential adverse effects.
Melatonin congeners like ramelteon (Rozerem) and tasimelteon (Hetlioz) selectively bind to melatonin receptors (MT1 and MT2) and thus mimic the actions of melatonin, a hormone that regulates sleep-wake cycles. Tasimelteon is primarily used for non-24-hour sleep-wake disorder, common in blind patients. They are also used to treat conditions like insomnia...

Inhalational Anesthetics: Overview01:20

Inhalational Anesthetics: Overview

1.3K
Inhalation anesthetics are drugs that induce general anesthesia upon inhalation. They work by increasing the sensitivity of GABAA receptors or inhibiting NMDA receptors, leading to a decrease in central nervous system activity. The depth of anesthesia can be rapidly adjusted by changing the concentration of the inhaled gas. Some common examples of inhalational anesthetics include volatile liquids like isoflurane, desflurane, sevoflurane and gases like xenon and nitrous oxide. Isoflurane, a...

CNS Depressants: Barbiturates and Benzodiazepines

1.5K
CNS depressants include drugs from the category of barbiturates and benzodiazepines. They are valuable medications for managing anxiety disorders and insomnia. Barbiturates, once used to induce and maintain sleep, have been replaced mainly by benzodiazepines due to barbiturate's toxicity, tolerance, and overdose risks. They interact with GABAA receptors, leading to sedation at low doses and potentially coma and death at higher doses. Phenobarbital, a long-acting barbiturate, possesses...

Area of Science:

  • Neurology
  • Hematology
  • Toxicology

Background:

  • Vitamin B12 deficiency is a well-known cause of hematological and neurological disorders.
  • Recreational nitrous oxide (N2O) abuse is increasingly recognized as a cause of vitamin B12 deficiency.

Observation:

  • A case of non-immune hemolytic anemia with leukopenia and acute severe neurological impairments is presented.
  • The patient's symptoms were attributed to severe vitamin B12 deficiency.

Findings:

  • Recreational N2O use can lead to profound vitamin B12 deficiency.
  • This deficiency can manifest as severe hematological abnormalities and neurological deficits.

Implications:

  • Highlights the potential neurological and hematological risks associated with recreational nitrous oxide use.
  • Emphasizes the importance of considering N2O abuse in the differential diagnosis of vitamin B12 deficiency with neurological symptoms.
