This pathway is influenced by peripheral dopamine activity, as coincubation of dopamine, a GLP-1RA, and a dopamine D2 receptor antagonist increases AMPK phosphorylation and subsequent activation of thermogenesis, likely through a dopamine D1-receptor-mediated mechanism [115]
Participants who had adapted to their maintenance doses early in the study often reported fewer side effects over time, supporting the concept that Retatrutides tolerability profile improves with continued weekly dosing
Early Phase 2 trial data have generated significant clinical interest, but retatrutide has not yet received MHRA or EMA authorisation and remains confined to research settings
Increasing the dose of exenatide is not recommended in patients with an estimated glomerular filtration rate (eGFR) of 30-60 mL/min/1.73 m 2 , it is contraindicated for use in patients with an eGFR of less than 30 mL/min/1.73 m 2 (123)
