Summary
The number of patients with lower extremity varicose veins has been increasing due to an aging population, with treatments divided into conservative and invasive methods. Current treatments can be expensive and inaccessible for some patients. Entelon, a relatively inexpensive intravenous drug, has shown promise in improving symptoms related to venous lymphatic dysfunction, but its objective vascular function improvement hasn't been proven. This study aims to assess the effectiveness of Entelon combined with lifestyle therapy in patients with varicose veins, using follow-up Doppler ultrasonography to measure venous reflux improvement.

Criteria
Inclusion Criteria:

1. Adult males and females aged between 19 and under 65 years old

2. Patients with the following findings on venous Doppler ultrasound examination:

- Superficial veins (such as the great saphenous vein, small saphenous vein, etc.)
showing valvular reflux for 0.5 seconds or longer

- Deep veins (such as the femoral vein, etc.) showing valvular reflux for 1 second
or longer

3. Patients who have completed the washout period as described below by Visit 2,
including the screening period:

- Analgesics, steroids, anti-inflammatory drugs, and venoactive medications (such
as Entelon, etc.): at least 4 weeks

2. Asymptomatic lower extremity varicose veins

3. Acute deep vein thrombosis

4. Frequent lower limb pain due to neuropathy

5. Patients who have undergone or are scheduled for varicose vein procedures/surgeries
(However, patients who have had a procedure or surgery more than 1 year prior to the
screening date are eligible to participate)

6. Patients diagnosed with systemic diseases causing edema or thrombosis, such as heart
failure, endocrine diseases (hypothyroidism, Cushing's syndrome, uncontrolled
diabetes), allergic reactions to medications, urticaria and angioedema, malabsorption
and protein-calorie malnutrition, obstructive sleep apnea, or thrombophilia, as
determined by the investigator

7. History of malignancy within the past 5 years, but the following cases are eligible
for clinical trial participation:

- Those who have a history within the past 5 years but maintain a cured state
without recurrence or metastasis

- Those who have completed treatment for their tumor and have been disease-free for
at least 5 years from the screening date

- Those who have passed at least 1 year since the screening date after complete
resection of basal cell carcinoma/squamous cell carcinoma, radical resection of
thyroid papillary cancer, or successful treatment of cervical intraepithelial
neoplasia

8. Severe renal dysfunction (serum creatinine levels more than twice the normal upper
limit of the institution) at the screening date

9. Severe liver dysfunction (ALT or AST levels more than three times the normal upper
limit of the institution) at the screening date

10. Need to receive diuretics or contraindicated medications and therapies that may affect
the results of this clinical trial during the study period (However, patients who have
been taking antihypertensive medications (calcium channel blockers, beta-blockers,
angiotensin-converting enzyme inhibitors, vasodilators, vasoconstrictors) at the same
dosage for at least 4 weeks (28 days) before screening and will maintain the same
dosage and administration during the study period are eligible to participate)

11. History of clinically significant psychiatric disorders or alcohol abuse

12. History of hypersensitivity reactions to the investigational drug or its ingredients

13. Those who have participated in or are scheduled to participate in other clinical
trials (investigational drugs, medical devices, health functional foods) within 12
weeks from the screening date

14. Pregnant or breastfeeding women

15. Women of childbearing potential who plan to become pregnant during the clinical trial
participation period

16. Individuals deemed unsuitable for participation in the clinical trial by the
investigator
