Oral Semaglutide Pharmacology

On this episode, I discuss the pharmacology of oral semaglutide. It is a GLP-1 agonist that is the first one in the class to have an oral formulation.

There is a recommended dose titration with oral semaglutide that can take a month or two to get therapeutic doses. I disucss this further in this episode.

The most common adverse effect of oral semaglutide is nausea.

Oral semaglutide is dosed once daily which is nice to try to maximize patient adherence.

Pioglitazone Pharmacology

pioglitazone pharmacology

On this episode, I cover pioglitazone pharmacology. The primary mechanism of action with pioglitazone is that it is an agonist at Peroxisome Proliferator Activated Receptor Gamma receptor. This improves insulin sensitivty in the periphery.

Two common side effects exist with pioglitazone. This drug can cause weight gain and also contribute to edema.

Pioglitazone has a boxed warning and is contraindicated in patients who have symptomatic heart failure.

There are a few potential interactions with pioglitazone. Trimethoprim and gemfibrozil can inhibit the breakdown of pioglitazone.

A couple of advantages of pioglitazone include that it is generic (inexpensive) and that it is dosed once daily.

GLP-1 Agonist Pharmacology

The GLP-1’s are a relatively newer class of medications used to lower blood sugars in diabetes.

GLP-1’s work by simulating the effects of incretin hormones in the body. They can help promote fullness, lower weight, and stimulate insulin release following a meal.

GLP-1’s can cause significant GI side effects. Nausea is by far the most common adverse effect. It can even lead to diarrhea and vomiting in some cases.

There is boxed warning on the GLP-1 agonists. Be aware of patients who have had a history of thyroid cancer as this may be a contraindication.

GLP-1 agonists can help lower A1C and stimulate weight loss which is a huge benefit for most patients with Type 2 diabetes.

SGLT-2 Inhibitors Pharmacology

On this episode, I discuss the mechanism of action of the SGLT-2 Inhibitors and how they lower blood sugar.

These drugs are classically used for diabetes and eliminate blood sugar through the urine.

One of the potential side effects is that these drugs can increase the risk of genital infections and urinary tract infections.

There is a boxed warning on canagliflozin for its potential to increase the risk of amputation.

These drugs also have a mild diuretic type effect and can potentially cause hypotension.
