Are you preparing for a colonoscopy?
A colonoscopy is an important procedure to check your colon health, and thoroughly cleansing your colon is essential for a successful examination.
At Ilwon Station Exit 1 Pharmacy, we will provide you with kind and detailed guidance about Haprep Powder, which is used for this purpose.
We’ll carefully explain everything—from the timing and method of taking Haprep Powder to precautions and tips for easier consumption!
What is Haprep Powder?
Haprep Powder is a prescription medication used to cleanse the colon before a colonoscopy. It is manufactured and distributed by Korea Pharmbio (manufacturer and distributor: Korea Pharmbio).
Haprep Powder contains polyethylene glycol (PEG) and electrolytes, effectively inducing bowel movements without irritating the colon. It must be taken according to your doctor’s instructions for precise colon cleansing before the procedure, and it is available with a prescription at Ilwon Station Exit 1 Pharmacy.
Active Ingredients and Their Role as Laxatives
- Polyethylene Glycol 3350 : Acts as an osmotic laxative by absorbing water into the colon, softening stool, and promoting its elimination. It’s safe as it doesn’t irritate the colon.
- Sodium Chloride : Maintains electrolyte balance and regulates osmotic pressure to draw water into the colon, inducing bowel movements.
- Potassium Chloride : Replenishes electrolytes to reduce the risk of dehydration and indirectly supports bowel movement.
- Anhydrous Sodium Sulfate : Increases water in the colon through an osmotic effect, thinning stool and aiding its expulsion as a laxative.
- Ascorbic Acid (Vitamin C) : Acts as an osmotic laxative at high concentrations by drawing water into the colon, while also improving the colon’s internal environment with its antioxidant properties.
