History of Respiratory Stimulants

Area of Science:

• Pharmacology
• Toxicology
• Medical History

Background:

• Interest in respiratory stimulants fluctuates with the emergence of respiratory depressant drugs.
• Opioids, barbiturates, and propofol are examples of central nervous system depressants causing respiratory depression.
• Recent increases in overdose deaths due to potent opioids and polysubstance use necessitate new solutions.

Purpose of the Study:

• To review the history of respiratory stimulants.
• To inform the renewed interest in respiratory stimulant medications.
• To present the trajectory of advances toward more selective and safer respiratory stimulants.

Main Methods:

• Historical review of respiratory stimulant medications.
• Analysis of trends in drug-induced respiratory depression and overdose.
• Examination of the development of opioid receptor antagonists.

Main Results:

• The development of respiratory stimulants has historically paralleled the rise and fall of specific drug classes causing respiratory depression.
• The availability of opioid receptor antagonists like naloxone has impacted overdose trends.
• Current overdose crises driven by fentanyl analogs and polysubstance use highlight the need for novel respiratory stimulants.

Conclusions:

• The historical context of respiratory stimulants is crucial for addressing contemporary overdose challenges.
• Advances in understanding drug mechanisms have paved the way for developing more targeted respiratory stimulant therapies.
• Further research into selective and safer respiratory stimulants is warranted to combat the growing overdose epidemic.
