Relationships
Editorial index: substances classified under stimulant. This index does not assert a combined effect. Compounds associated with increased arousal; mechanisms and risks differ.
- Stimulantindex concept
- Caffeineindexed substance
- Nicotineindexed substance
- Modafinilindexed substance
- Methylphenidateindexed substance
Editorial index: substances classified under adenosine antagonist. This index does not assert a combined effect. Blocks adenosine receptor signaling.
- Adenosine antagonistindex concept
- Caffeineindexed substance
Editorial index: substances classified under nicotinic agonist. This index does not assert a combined effect. Activates nicotinic acetylcholine receptors.
- Nicotinic agonistindex concept
- Nicotineindexed substance
Editorial index: substances classified under adenosine. This index does not assert a combined effect. A neuromodulator involved in sleep pressure and arousal.
Source 1 ↗Editorial index: substances classified under acetylcholine. This index does not assert a combined effect. The endogenous transmitter at nicotinic and muscarinic receptors.
- Acetylcholineindex concept
- Nicotineindexed substance
Editorial index: substances classified under adenosine receptors. This index does not assert a combined effect. Receptors activated by adenosine; caffeine antagonism changes signaling without removing the physiological need for sleep.
- Adenosine receptorsindex concept
- Caffeineindexed substance
Editorial index: substances classified under nicotinic acetylcholine receptors. This index does not assert a combined effect. Ligand-gated receptors activated by acetylcholine and nicotine. Receptor subtypes and desensitization affect the response.
- Nicotinic acetylcholine receptorsindex concept
- Nicotineindexed substance
Caffeine's adenosine antagonism connects a molecule, mechanism, transmitter system and functional class.

Relationship nodes connect multiple concepts in one sourced statement. Member roles identify the substance, biological target, measured outcome, or exposure context. Editorial index relationships group classifications. Connections are not recommendations to combine substances.
