Dpp 4 vs Sglt2
Introduction
For patients with type 2 diabetes, certain drugs that alter the concentrations of compounds in the body linked to glucose regulation can help maintain stable blood sugar levels and manage symptoms. DPP-4 inhibitors and SGLT2 inhibitors are two such classes of drugs prescribed for this condition. They each impact different physiological processes but both work towards maintaining a healthy balance of glucose in patients with diabetes.
Dipeptidyl peptidase-4 (DPP-4) inhibitors function by blocking the action of DPP-4 enzymes which break down incretin hormones, thus increasing their concentration. Incretin hormones stimulate insulin production and inhibit glucagon release which ultimately reduces blood glucose levels.
On the other hand, Sodium-glucose co-transporter 2 (SGLT2) inhibitors primarily affect renal functions by inhibiting reabsorption of filtered glucose from kidneys back into bloodstream, thereby promoting its excretion through urine. This unique mechanism helps lower blood sugar levels without directly interfering with insulin or glucagon pathway.
What is Dpp 4?
Dipeptidyl Peptidase 4 (DPP-4) inhibitors and Sodium-Glucose Co-Transporter 2 (SGLT2) inhibitors are two different classes of medications used in the management of type 2 diabetes. DPP-4 inhibitors, such as sitagliptin, were first approved by the FDA in 2006. They work by increasing levels of incretin hormones like GLP-1 which help to lower blood sugar levels by stimulating insulin secretion and reducing glucagon release. This means that they effectively trap more glucose in cells where it can be used for energy rather than allowing it to circulate freely in the bloodstream.
On the other hand, SGLT2 inhibitors like dapagliflozin have a different mechanism of action. Approved by the FDA in 2013, they reduce blood sugar levels by preventing glucose reabsorption in kidneys and promoting its excretion through urine instead. Both classes have their unique benefits with DPP-4 having fewer side effects due to its selective inhibition but SGLT2 potentially offering additional cardiovascular benefits beyond just glucose control.
What conditions is Dpp 4 approved to treat?
DPP-4 inhibitors and SGLT2 inhibitors are used for the management of varying types of diabetes:
- Dipeptidyl peptidase 4 (DPP-4) inhibitors are approved for the treatment of type 2 diabetes as a monotherapy or in combination with other antidiabetic drugs.
- Sodium-glucose co-transporter 2 (SGLT2) inhibitors are approved not only for improving glycemic control in patients with type 2 diabetes but also to reduce the risk of major cardiovascular events in patients with established cardiovascular disease. They've recently been approved to slow progression of kidney disease and lower risk of hospitalization from heart failure too.
How does Dpp 4 help with these illnesses?
DPP-4 inhibitors help manage type 2 diabetes by increasing the level of incretin hormones in the body. These hormones are involved in the regulation of glucose metabolism and they work by stimulating insulin secretion from beta cells in response to meals, inhibiting glucagon release (which reduces hepatic glucose production), and delaying gastric emptying. DPP-4 is an enzyme that breaks down these incretin hormones, so by inhibiting this enzyme, there will be more incretins available which can lead to a reduction in blood sugar levels.
On the other hand, SGLT2 inhibitors also assist with managing type 2 diabetes but through a different mechanism. They block sodium-glucose co-transporter 2 proteins found predominantly in kidney tubules leading to increased excretion of glucose into urine thereby reducing blood glucose levels.
Both types of medications aim at controlling high blood sugar levels associated with type 2 diabetes but they do it via distinct mechanisms giving physicians flexibility when choosing treatment plans based on individual patient needs and conditions.
What is Sglt2?
SGLT2 inhibitors (sodium-glucose co-transporter 2) are a class of medications that, in contrast to DPP-4 inhibitors (dipeptidyl peptidase 4), work by preventing the reabsorption of glucose in the kidneys. They increase glucose excretion through urine which results in lowered blood sugar levels. This mechanism of action is independent from insulin and thus they do not cause hypoglycemia when used alone.
SGLT2 was first approved by the FDA as a diabetes treatment option in 2013. They come under several brand names such as Invokana, Farxiga, and Jardiance among others. As SGLTs do not inhibit DPP-4, their side effect profile is different than that of DPP-4 inhibitors with common side effects being genital yeast infections due to increased urinary glucose levels providing an environment for yeast growth.
Their unique mode of action can be beneficial for people with type 2 diabetes who have not responded well to other medication options like metformin or sulfonylureas - typical first-line drugs for managing Type 2 Diabetes.
What conditions is Sglt2 approved to treat?
SGLT2 inhibitors are a class of medications that are approved for the treatment of:
- Type 2 diabetes, as they work by helping the kidneys get rid of glucose from your bloodstream.
- Heart failure, specifically in patients with type 2 diabetes and established cardiovascular disease. The unique mechanism of action allows SGLT2 inhibitors to lower blood sugar levels while also offering benefits such as weight loss and blood pressure control.
How does Sglt2 help with these illnesses?
Sodium-glucose co-transporter 2 (SGLT2) inhibitors are a class of medications that function by modulating the reabsorption of glucose in the kidneys, thereby promoting its excretion in urine. This unique mechanism can lead to an improvement in blood sugar control for patients with diabetes, as well as other potential benefits such as weight loss and lowering blood pressure. Compared to Dipeptidyl Peptidase-4 (DPP-4) inhibitors which work by increasing levels of incretin hormones, SGLT2 inhibitors may provide more comprehensive management for diabetic patients due to their multi-faceted action on not just glycemic control but also body weight and cardiovascular health. Therefore, SGLT2 inhibitors might be prescribed when a patient does not respond optimally to "typical" oral antidiabetic drugs like DPP-4 inhibitors or may be combined with them for enhanced therapeutic efficacy.
How effective are both Dpp 4 and Sglt2?
Both DPP-4 inhibitors and SGLT2 inhibitors have proven efficacy in managing type 2 diabetes, and they were approved by the FDA within a decade of each other. As they act on different pathways involved in glucose regulation, they may be prescribed under varying circumstances. A double-blind clinical trial in 2013 directly studied Saxagliptin (a DPP-4 inhibitor) and Canagliflozin (an SGLT2 inhibitor), noting similar effectiveness at reducing HbA1c levels - a key indicator of blood sugar control over time.
A meta-analysis conducted in 2015 showed that DPP-4 inhibitors effectively lower blood glucose without causing weight gain or significantly increasing the risk for hypoglycemia compared to placebo or other antidiabetic drugs. They are typically well tolerated with few side effects, making them suitable for broad populations, including older adults.
On the other hand, SGLT2 inhibitors not only effectively reduce blood glucose levels but also induce weight loss and lower systolic and diastolic blood pressure which can be beneficial to many patients with type 2 diabetes who are often overweight or obese and hypertensive. However, these agents come with an increased risk of genitourinary infections compared to DPP-4 inhibitors.
In conclusion, both classes offer unique benefits: DDP-4 inhibitors are generally safer but less potent than SGLT2s; whereas while being more effective in controlling glycemic parameters along with added advantages like weight loss & BP reduction , SLGT2s carry higher risks such as genital tract infections & euglycemic ketoacidosis.
Nonetheless due to their different mechanisms of action either class could be chosen based on individual patient needs such as those requiring drastic lowering of HbA1C might benefit from using SGTL2 while elderly patients prone to urinary tract infection might do better on a regimen involving DDP-4's .
At what dose is Dpp 4 typically prescribed?
DPP-4 inhibitors are usually prescribed at a dosage of 100 mg/day for adults with type 2 diabetes. However, studies show that this dose is sufficient to control blood sugar levels in most individuals. For those who do not respond as expected, the dosage can be increased after several weeks under close medical supervision.
SGLT2 inhibitors, on the other hand, often start at an initial dose of 10 mg/day for adults diagnosed with type 2 diabetes. If needed and tolerated well by the patient without adverse side effects, this may be gradually increased to a maximum daily dosage of 25 mg.
Remember that these medications should always be taken under medical guidance and regular monitoring is necessary to ensure they’re achieving their purpose safely and effectively.

At what dose is Sglt2 typically prescribed?
SGLT2 inhibitor treatment is generally initiated at a dosage of 100 mg once daily, taken before the first meal of the day. The dose can then be increased to 300 mg/day if necessary and as tolerated by the patient. For those with moderate kidney function impairment, however, maximum dosing should not exceed 100mg per day due to reduced drug efficacy and increased risk of side effects. It's important for patients on SGLT2 inhibitors to monitor their glucose levels regularly as they may run a risk of hypoglycemia (low blood sugar) if combined with certain other diabetes medications. If after several weeks there is no adequate response or improvement in blood sugar control, your doctor might consider additional medication or adjust your current therapy plan.
What are the most common side effects for Dpp 4?
Common adverse effects of DPP-4 inhibitors can include:
- Nasopharyngitis (inflammation of the nose and throat)
- Headache
- Nausea
- Hypoglycemia (low blood sugar levels)
- Pancreatitis (inflammation in the pancreas)
On the other hand, SGLT2 inhibitors may cause:
- Genital yeast infections
- Urinary tract infections
- Thirst
- Increased urination
- Constipation or diarrhea -Nausea
It's important to note that while these side effects are possible, they do not occur in everyone. If you're considering either drug type for managing your diabetes, it's vital to discuss potential risks and benefits with your healthcare provider.
Are there any potential serious side effects for Dpp 4?
In some cases, DPP-4 inhibitors and SGLT2 inhibitors can lead to potentially serious side effects. For DPP-4 inhibitors, watch out for:
- Severe joint pain
- Skin reactions like hives, blistering or peeling skin
- Swelling in your face or throat that makes it difficult to breathe
- Pancreatitis symptoms such as severe stomach pain that spreads to your back with or without vomiting
For SGLT2 inhibitors:
- Symptoms of urinary tract infections including burning sensation when urinating, frequent urge to urinate, lower abdominal pain and bloody or cloudy urine
- Yeast infections in men and women: redness, itching, rash around the genitals
- Unusual thirst indicating high blood sugar levels
Low blood pressure (feeling light-headed or faint) particularly if you are on diuretics or medications lowering blood pressure.
And for both types of medication:
Symptoms of heart failure - shortness of breath; swelling in legs/ankles/feet; unusual tiredness; sudden weight gain. Any signs of allergic reaction such as difficulty breathing; swelling of your face,lips,tongue,and throat.
If any such symptoms occur while taking either type of medication should consult a healthcare professional immediately.
What are the most common side effects for Sglt2?
SGLT2 inhibitors, used in the management of type 2 diabetes, come with their own set of potential side effects including:
- Increased urination
- Yeast infections due to increased sugar in urine
- Urinary tract infections
- Thirst and dry mouth due to dehydration from frequent urination
- Nausea and stomach discomfort
- Dizziness or light-headedness, particularly upon standing up
- Skin rash or itching
- Weight loss as body starts using alternative energy source (fat) It's also worth noting that SGLT2 inhibitors may increase the risk for lower limb amputations and bone fractures.
Are there any potential serious side effects for Sglt2?
SGLT2 inhibitors are generally safe and effective for treating type 2 diabetes, but like all medications, they can cause side effects. Here's what to look out for:
- Signs of an allergic reaction: these could be hives, itching, difficulty breathing or swallowing
- Symptoms of urinary tract infections (UTIs) or yeast infections in women and men: these include burning sensation during urination, frequent urge to urinate, pelvic pain in women and penile redness or swelling in men
- Ketoacidosis symptoms: nausea, vomiting, stomach-area pain, tiredness and trouble breathing
- Low blood sugar (hypoglycemia): watch out for shaking hands/feet/tremors; sweating; rapid heartbeat; hunger pangs; dizziness/faint feelings etc.
- Kidney problems - dehydration signs include dizziness/fainting/light-headedness from low blood pressure especially when standing up after sitting/lying down a while
Please note that this is not an exhaustive list. Always consult your healthcare provider if you experience any unusual symptoms while taking SGLT2 inhibitors.
Contraindications for Dpp 4 and Sglt2?
Both DPP-4 inhibitors and SGLT2 inhibitors, along with most other diabetes medications, may cause some side effects in certain individuals. If you notice symptoms such as persistent nausea, vomiting, stomach/abdominal pain, unusual tiredness or weakness developing or worsening after beginning these treatments, seek immediate medical attention.
Neither DPP-4 nor SGLT2 inhibitors should be taken if you are currently on or have recently been treated with drugs known to interact negatively with them. Always inform your healthcare provider about any medication you are taking; these can include prescription drugs, over-the-counter medicines and herbal products. Drugs known for harmful interactions will require a suitable period of discontinuation before starting therapy with either DPP-4 or SGLT2 inhibitors.
Please note that both classes of drug hold the potential risk of causing serious conditions like pancreatitis (DPP-4) and diabetic ketoacidosis (SGLT2). Furthermore, patients who have severe kidney disease should not take SGLT2 inhibitors due to an increased risk of side effects.
How much do Dpp 4 and Sglt2 cost?
For the brand-name versions of these drugs:
- The price for DPP-4 inhibitors, such as Januvia (sitagliptin), is approximately $500 for 30 tablets (100 mg), which works out to be about $16.50 per day.
- For SGLT2 inhibitors like Jardiance (empagliflozin), a month's supply costs roughly $540 for 30 tablets of 25mg each, or around $18 per day.
Thus, if you are taking average doses of either drug, then the cost difference between DPP-4 inhibitors and SGLT2 inhibitors is small. However, it should be noted that the choice between these two classes of medication shouldn't primarily depend on cost but rather efficacy and side effect profile in relation to your individual health status.
For generic versions - currently there aren't any FDA approved generics available in the U.S market for both medications which means prices remain high compared to other diabetes medications with generic alternatives. Please consult with your healthcare provider for suitable options based on clinical effectiveness and affordability.
Popularity of Dpp 4 and Sglt2
Dipeptidyl peptidase-4 inhibitors (DPP-4), in both generic and brand names, were estimated to have been prescribed to about 6.6 million people in the US in 2020. DPP-4 accounted for just over 15% of antidiabetic prescriptions in the US, primarily used as a second-line treatment when metformin alone does not control blood sugars effectively. DPP-4 has seen a relatively steady prevalence since its introduction.
Sodium-glucose co-transporter 2 inhibitors (SGLT2), including brand versions such as Jardiance and Invokana, were prescribed to approximately 3 million people in the USA in 2020. In the US, SGLT2 accounts for around 7% of overall antidiabetic prescriptions. The utilization rate of SGLT2 drugs has increased significantly over recent years due to their benefits on heart health and weight loss beyond mere blood sugar control.
Conclusion
Both DPP-4 inhibitors and SGLT2 inhibitors are widely used in the management of type 2 diabetes, and have been shown to be more effective than placebo treatments in managing blood glucose levels. In some cases, these drugs may be combined for a synergistic effect on glycemic control, but this should always be under careful consideration by a healthcare provider due to potential drug interactions. Their mechanisms of action differ significantly: DPP-4 inhibitors work primarily by increasing incretin levels (which inhibit glucagon release) and thereby reducing fasting and postprandial glucose levels; SGLT2 inhibitors act largely by preventing the reabsorption of glucose in the kidney, leading to increased excretion of glucose via urine.
Both classes of drugs are available as generics which can lead to significant cost savings for patients who need long-term medication. The therapeutic effects might not be noticeable immediately as both may require an adjustment period.
The side effect profiles between these two classes vary depending on individual medications within each class but tend to be generally well-tolerated. However, SGLT2s come with unique risks such as urinary tract infections and ketoacidosis whereas DPP-4s could potentially cause joint pain or pancreatitis. Thus, it's vital that patients monitor their health status closely while taking either medication class, seeking immediate medical help if there's any worsening condition or unusual symptoms.
