Alogliptin, marketed under the brand name Nesina, is primarily indicated for the management of type 2 diabetes mellitus in adults. Alogliptin functions by inhibiting the enzyme dipeptidyl peptidase-4 (DPP-4), thereby enhancing the levels of incretin hormones like glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP). 

Alogliptin can be prescribed as a monotherapy or in combination with other antidiabetic medications, such as metformin, sulfonylureas, or insulin, depending on the individual’s needs and treatment goals. 

By effectively lowering blood sugar levels, alogliptin helps to reduce the risk of long-term complications associated with uncontrolled diabetes, such as cardiovascular disease, kidney damage, nerve damage, and vision problems.

Alogliptin, a member of the dipeptidyl peptidase-4 (DPP-4) inhibitor class, exerts its therapeutic effects through a precise mechanism within the body’s glucose regulation system.

Alogliptin inhibits the activity of the enzyme dipeptidyl peptidase-4 (DPP-4), which is responsible for the rapid degradation of incretin hormones, specifically glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP).

By inhibiting DPP-4, alogliptin prolongs the action of GLP-1 and GIP. This prolongation enhances the physiological responses initiated by these hormones, including the stimulation of insulin secretion and the inhibition of glucagon release from the pancreas.

The increased levels of GLP-1 and GIP lead to enhanced insulin secretion from pancreatic beta cells in response to elevated blood glucose levels. Additionally, glucagon secretion from pancreatic alpha cells is suppressed, further contributing to the reduction of blood sugar levels.

Common Side Effects:

• Headache: Mild to moderate headaches may occur, particularly during the initial stages of treatment.
• Upper Respiratory Tract Infections: Patients may experience symptoms such as a sore throat, cough, or nasal congestion.
• Nasopharyngitis: Inflammation of the nose and throat, often presenting with symptoms like a runny or stuffy nose.
• Allergic Reactions: Some individuals may develop allergic reactions, including rash, itching, or hives.

Serious Side Effects:

• Pancreatitis: A rare but severe side effect characterized by inflammation of the pancreas, presenting with symptoms such as severe abdominal pain, nausea, and vomiting.
• Severe Joint Pain: Alogliptin use has been associated with severe joint pain, which may require medical intervention and discontinuation of the medication.
• Bullous Pemphigoid: A rare autoimmune skin disorder characterized by the formation of fluid-filled blisters on the skin and mucous membranes.
• Kidney Problems: Some patients may experience worsening kidney function or other renal complications, necessitating close monitoring by healthcare professionals.

Alogliptin should be used cautiously in patients with a history of pancreatitis or with predisposing factors for pancreatitis. Healthcare providers should monitor patients for signs and symptoms of pancreatitis, such as severe abdominal pain, nausea, and vomiting.

Alogliptin may increase the risk of hypoglycemia, especially when used in combination with other antidiabetic medications like insulin or sulfonylureas. Patients should be educated about the signs and symptoms of hypoglycemia and instructed on appropriate management strategies.

Patients with moderate to severe renal impairment may require dosage adjustments or closer monitoring while taking alogliptin. Healthcare providers should assess renal function before initiating treatment and periodically thereafter.

Patients should be monitored for signs of allergic reactions, including rash, itching, or hives. If an allergic reaction occurs, alogliptin should be discontinued, and appropriate medical treatment initiated.

The safety of alogliptin use during pregnancy and lactation has not been established. Healthcare providers should weigh the potential risks and benefits before prescribing alogliptin to pregnant or breastfeeding women. Alternative treatment options may be considered whenever possible.

Alogliptin metabolism may be affected by drugs that induce or inhibit the cytochrome P450 3A4 (CYP3A4) enzyme system. Concurrent use of CYP3A4 inducers (e.g., rifampin, carbamazepine) may decrease alogliptin plasma concentrations, potentially reducing its efficacy.

Co-administration of alogliptin with insulin or sulfonylureas may potentiate the hypoglycemic effects of these medications. Close monitoring of blood glucose levels is recommended, and dosage adjustments of insulin or sulfonylureas may be necessary to prevent hypoglycemia.

Alogliptin may potentiate the effects of angiotensin-converting enzyme (ACE) inhibitors on blood pressure reduction. Patients taking both alogliptin and ACE inhibitors should be monitored for hypotension, especially during the initiation of therapy or dosage adjustments. 

The typical dosage of alogliptin for the management of type 2 diabetes mellitus is 25 mg once daily, with or without food. This dosage is generally well-tolerated and effective for most patients. 

However, dosage adjustments may be necessary in certain situations:Patients with moderate to severe renal impairment (creatinine clearance less than 60 mL/min) should receive a lower dosage of alogliptin to reduce the risk of drug accumulation and potential adverse effects. The recommended dosage for patients with renal impairment is 12.5 mg once daily.

Alogliptin is primarily metabolized by the liver, but hepatic impairment is not expected to significantly affect its pharmacokinetics. Therefore, dosage adjustment is not required for patients with hepatic impairment.

No dosage adjustment is necessary based solely on age. However, elderly patients may be more susceptible to the effects of alogliptin, and careful monitoring is recommended, especially during initiation of therapy.

When alogliptin is used in combination with other antidiabetic medications, such as metformin, sulfonylureas, or insulin, dosage adjustments of those medications may be necessary to achieve optimal glycemic control while minimizing the risk of hypoglycemia. 

• Alogliptin is available only with a valid prescription from a licensed healthcare provider.
