GLP-1R activation of neuroprotective pathways in neurons, microglia and astrocytes has also been reported: improvements in overall cognition, learning and motor function potentially associated with GLP-1RA administration in Alzheimers disease and Parkinsons disease may be mediated not only by their amyloid pathology-ameliorating properties (A, tau and -synuclein), but also the suppression of Ca 2+ deregulation and endoplasmic reticulum stress, anti-inflammatory activity, blockage of oxidative stress, mitochondrial dysfunction and apoptosis pathways, enhancements in the neuronal insulin sensitivity and energy metabolism, functional improvements in autophagy and mitophagy, elevated brain-derived neurotrophic factor and glial cell line-derived neurotrophic factor synthesis, and neurogenesis 36
Dulaglutide was used in 11 patients (14%), exenatide in three patients (3.8%) and two patients received orally administered semaglutide ( n = 2, 2.6%, PIONEER 7 study participants, NCT02849080) before switching to semaglutide

At 240 calories, it may need a boost (like fruit or nut butter) to fully replace a meal
For example, a vial might contain 2 mg or 5 mg of semaglutide
