Acute toxicity in animal models is described as low for all three peptides individually, but coadministration data are sparse
Studies show up to 20-60 percent of people stop treatment within the first year, and widespread use of the drug in doses below the recommended amounts
Using PROMs for routine symptom assessment can help monitor these changes and support clinical decision-making
These metabolites can be detected in urine and bile
