glp-1 agonists oral Small-Molecule Receptor Agonists: Mechanistic Insights and Emerging Therapeutic Strategies Comparing Ozempic, Wegovy and Other

Be very cautious about OTC products marketed as GLP-1 alternatives most lack clinical evidence

2) Of the weight lost, what proportion came from lean or muscle-related compartments

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

95% CI 0.27, 0.92) in the orally administered semaglutide group

Special considerations for compounded GLP-1 formulations Many people taking GLP-1 medications use compounded formulations rather than brand-name products
