- PE-22-28 represents a different paradigm from conventional antidepressants. Understanding these differences helps contextualize its potential role in research and future therapeutic development.
- SSRIs work by blocking serotonin reuptake transporters. This increases serotonin availability in synapses but does not change how much serotonin neurons produce. Effects require weeks to manifest fully as the brain adapts to altered serotonin dynamics. Side effects include sexual dysfunction, emotional blunting, and discontinuation symptoms.
- SNRIs add norepinephrine reuptake inhibition to serotonin effects. This may help certain symptom profiles but adds blood pressure and heart rate effects to the side effect burden.
- Tricyclic antidepressants affect multiple neurotransmitter systems simultaneously. Their lack of selectivity produces anticholinergic effects like dry mouth, constipation, and cognitive impairment. Overdose danger limits their use.
- Ketamine represents the recent breakthrough in fast-acting antidepressants. It works through NMDA receptor blockade and produces rapid effects within hours. But it requires supervised administration due to dissociative effects and has abuse potential.
