GLP-1
Overview
O GLP-1 (Peptídeo Semelhante ao Glucagon tipo 1) na forma de semaglutida é o tratamento mais validado para perda de peso baseado em peptídeos. Aprovado pela FDA como Ozempic (diabetes) e Wegovy (obesidade), demonstra ~15% de perda de peso em ensaios clínicos de larga escala. Original in PT-BR
GLP-1 is catalogued under Metabolic. 10 Eagle articles in this library reference this compound.

Mechanism
Agonista do receptor GLP-1 — reduz apetite e melhora controle glicêmico Original in PT-BR
A semaglutida é um análogo do GLP-1 humano com 94% de homologia, modificado com um ácido graxo C-18 para se ligar à albumina plasmática (meia-vida ~7 dias vs minutos do GLP-1 nativo). Atua em múltiplos receptores GLP-1: no pâncreas (aumenta secreção de insulina glicose-dependente), no estômago (retarda esvaziamento gástrico), no hipotálamo (reduz apetite e aumenta saciedade), e no sistema cardiovascular (efeitos cardioprotetores). O retardo do esvaziamento gástrico combinado com a ação central no apetite produz redução calórica sustentada sem a sensação de privação típica de dietas. Original in PT-BR

Interactions
This section brings together two origins. The ones Eagle wrote come from its own curated library, one by one; the rest come from the imported reference material, which records one label and one comment per pair and no source. Neither kind carries a PMID, a population or model, or a degree of certainty. Eagle did not verify the imported ones and does not endorse them. «Compatible», «Caution» and «Avoid» are not an Eagle authorisation or prohibition, and none of this is medical advice.

Ambos agonistas GLP-1R — NÃO combinar (mecanismo duplicado) Original in PT-BR
Overlapping GLP-1 agonism — tirzepatide already activates the GLP-1 receptor.
Avoid
