The new biology and pharmacology of glucagon
The first studies evaluating the effects of GLP-1 and exendin-4 in neuronal cells demonstrated their ability to promote neurite outgrowth (a similar effect to that observed with the neurotrophic nerve growth factor) and to protect cultured neurons against glutamate-induced apoptosis [33]
A 2025 Institute for Clinical and Economic Review (ICER) report notes that weekly GLP-1s like semaglutide (Ozempic/Wegovy) and tirzepatide (Mounjaro/Zepbound) have become more cost-effective over time due to price reductions and proven long-term benefits ( [11] )
Conversely, oral administration is constrained by enzymatic breakdown, acidic pH, and limited epithelial permeability
The approval is backed by positive findings from three Phase III trials, a Phase II dose-ranging study, and two Phase I pharmacokinetic studies
Nevertheless, the utilization of metformin during pregnancy is typically determined following a collaborative evaluation of the potential risks and benefits by obstetricians and reproductive endocrinologists in current clinical practice
