If you experience nausea after tirzepatide, that symptom is unrelated to whether you recently ate before injectionnausea occurs because tirzepatide slows your stomach's emptying rate, not because of your injection timing relative to meals

This process involves neural circuits modulated by neuropeptides, such as corticotropin-releasing factor.150 Dopamine plays a central role in mediating the immediate reinforcing effects of drugs, and dysregulation of the dopaminergic system has been proposed as a predisposing factor for chronic substance use and the maintenance of addiction.151 Dopaminergic neurons originating in the VTA project to the NAcc, amygdala, hippocampus, and prefrontal cortex, while those from the substantia nigra project to the dorsal striatum.152 The activation or disinhibition of VTA dopaminergic neurons is critical for the potentiation of alcohol, nicotine, and opioids.152 Cocaine exerts its effects by inhibits dopamine reuptake by blocking dopamine transporters, thereby increasing or prolonging synaptic dopamine concentrations.152 Other central nervous system stimulants elevate synaptic dopamine via mechanisms such as dopamine reuptake inhibition, reversal of dopamine transporter function, and promotion of dopamine release.153 However, the mechanisms by which GLP-1 receptor stimulation modulates dopaminergic function remain unclear

Two phase 3 studies have now been reported (Behavioral Modification and Lorcaserin for Overweight and Obesity Management [BLOOM] [39] and BLOSSOM [40]) and have shown a modest but significant placebo-adjusted weight reduction
