Trulicity is available as 0.75 mg and 1.5 mg subcutaneous once-weekly injections. These drugs exert their effects by acting as incretin mimetics.

Hence, they both cause the release of insulin and suppress glucagon in a glucose-dependent mechanism.

When glucose is elevated in the plasma, they cause the release of insulin and simultaneously suppresses glucagon levels.

These drugs also inhibit the motility of the stomach and delay gastric emptying.

This can cause nausea, vomiting, abdominal fullness, bloating, and suppresses the appetite. Thus, they may also have a weight-losing effect.

However, the FDA has approved Semaglutide only for the management of obesity. Dulaglutide is only approved for the management of diabetes.

I am an Internist practicing medicine for the last fifteen years. Over the years, I have learned that medicine is not about prescribing pills. True medical practice is helping people.
I do prescribe pills as well but the best results I get are when I motivate people to overcome their problems with little changes in their lifestyles.
Since most of my patients are obese, have diabetes, hypertension, high cholesterol levels, I am writing at dibesity.com when free.
Dibesity, I know the correct word is diabesity. Ignore this! Be with us.
