This comprehensive guide explains everything patients need to understand about dapagliflozin tablets, their uses, proper dosage, potential side effects, and necessary precautions. 

Was ist Dapagliflozin?

Dapagliflozin is a prescription medication that belongs to a class of medicines called sodium-glucose co-transporter 2 (SGLT2) inhibitors. Doctors generally prescribe dapagliflozin tablets to manage type 2 diabetes along with a diet and exercise regimen. As a result of its ability to decrease the risks of cardiovascular (heart or blood vessel) disease and multiple cardiovascular risk factors, Dapagliflozin has been added to the WHO's List of Essential Medicines.

• Type 2 Diabetes Management: It helps control Blutzucker levels in patients aged 10 years and older
• Heart Failure Treatment: Decreases the risk of hospitalisation and urgent heart failure visits
• Kidney Disease Care: Helps slow down the progression of chronic kidney disease (CKD) and reduces the risk of end-stage kidney disease
• Cardiovascular Protection: Lowers the risk of cardiovascular death in patients with heart disease

How to Use Dapagliflozin Tablet

  • Assess kidney function periodically
  • Monitor blood pressure and volume status
  • Track blood sugar levels, especially when combined with other diabetes medications
• Essential Safety Measures: Patients should maintain adequate fluid intake, especially during exercise or hot weather. This becomes especially crucial as dapagliflozin can cause Austrocknung, which may lead to dizziness or Ohnmacht.

How Dapagliflozin Tablet Works

The science behind dapagliflozin's effectiveness lies in its unique interaction with the kidneys. This medication targets a specific protein called sodium-glucose co-transporter 2 (SGLT2), found in the kidneys' proximal tubules.

In normal kidney function, SGLT2 helps reabsorb glucose back into the bloodstream. However, Dapagliflozin blocks this process, leading to several beneficial effects:

• Increases glucose excretion through urine
• Reduces sodium reabsorption
• Decreases pressure in blood vessels
• Lowers the workload on the heart
• Reduces inflammation in the kidneys

It ranks as the second most potent medication in its class, with a maximal half-inhibitory concentration of 1.2 nM (nano Molars). This means it can work efficiently at lower doses compared to similar medicines.

Can I Take Dapagliflozin with Other Medicines?

Patients taking dapagliflozin should be aware of its interactions with other medications. 

Wichtige Wechselwirkungen zwischen Medikamenten:

• Blood pressure medicines like ramipril or Amlodipin
• Chloroquin
• Ciprofloxacin
• Diuretics (water tablets)
• Insulin or other diabetes medications
• Lithium 
• Einige Antidepressiva

Dosierungsinformationen

For type 2 diabetes management, patients typically start with 5 mg once daily. Doctors may increase this to 10 mg daily for better blood sugar control if needed. However, for heart failure and chronic kidney disease, the standard dose is 10 mg once daily.

When prescribed with other medications, the dosing schedule may vary:

• Dapagliflozin with Metformin: Available in two strengths - 5mg dapagliflozin with either 850mg or 1g metformin, taken twice daily
• Dapagliflozin with Saxagliptin: A fixed dose of 10mg dapagliflozin and 5mg saxagliptin, taken once daily

Fazit

Dapagliflozin stands as a valuable medication for patients with type 2 diabetes mellitus, heart failure, and kidney disease. The medication helps remove excess glucose through urine while protecting vital organs. Studies show its effectiveness both as a standalone treatment and when combined with other diabetes medications.

Patients who take Dapagliflozin correctly and follow their doctor's guidance see the best results. Regular monitoring, proper hydration, and awareness of potential side effects play key roles in successful treatment. The medication's proven track record, backed by extensive research and millions of prescriptions, makes it a trusted choice for managing multiple health conditions.

Doctors can help determine if dapagliflozin suits a patient's specific needs. The correct dosage, careful monitoring, and proper combination with other medications ensure patients receive maximum benefits while minimising risks.

Häufig gestellte Fragen

Dapagliflozin begins working within 2 hours of taking the first dose. However, it may take up to a week for the complete Blutzucker-lowering effect to become apparent. For heart failure patients, improvements in symptoms might take 1-2 months to notice.

2. Was passiert, wenn ich eine Dosis verpasse?

If a patient misses a dose and it's 12 hours or more until their next scheduled dose, they should take the missed dose immediately. However, if it's less than 12 hours until the next dose, they should skip the missed Dapagliflozin dose and continue with their regular schedule.

3. Was passiert bei einer Überdosis?

In case of a dapagliflozin overdose, patients should seek immediate medical attention. Taking too much dapagliflozin can cause low blood sugar. Patients experiencing overdose symptoms should consume quick-acting sugar sources like fruit juice or sugar cubes.
