The dual glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptor agonist tirzepatide: a novel cardiometabolic therapeutic prospect

The mechanisms of action involve modulation of sleep-regulating neurotransmitters and neuroendocrine systems including enhancement of delta wave activity during deep sleep stages, regulation of cortisol and stress hormone rhythms that impact sleep quality, optimization of circadian rhythm signaling for proper sleep-wake cycles, support for melatonin and sleep-promoting pathways, and modulation of pain perception which can interfere with sleep quality

The safety data for each compound individually is reassuring, but combination safety requires its own evaluation because pharmacological interactions can produce unexpected results even when each agent is well-characterized on its own
