Advantages over Lactulose-based Laxatives:
Composition:
- Macrogol 3350-based medication: Polyethylene glycol chains that are biologically inert, which means they do not ferment, metabolize, or get absorbed, and are completely excreted in stool.
- Lactulose-based medications: A synthetic disaccharide that, while not absorbed in the intestines, is fermented by bacteria in the colon, producing gases such as CO2 and NH4+.
Mechanism of Action:
- Constipass with Macrogol 3350 uses only the available water when the medication is dissolved or water already present in the intestines, avoiding electrolyte imbalances and gut microbiota disruption, thus minimizing bloating or indigestion.
- In contrast, lactulose attracts water into the intestines, which can lead to water-electrolyte imbalances if used long-term and cause bloating and discomfort due to fermentation gases.
Effectiveness and Safety:
- Macrogol 3350 in Constipass is safe and generally free from the discomforts like bloating, flatulence, or dehydration seen with Lactulose.
- Constipass can be used long-term.
- Constipass leads to higher frequency of bowel movements per week compared to Lactulose (supported by recommendations from the European Digestive Health Organization).
Macrogol 3350 Advantages over Macrogol 4000-based Products:
- Macrogol 3350 in Constipass has a lower molecular weight, meaning it can draw more water at the same dose, acting faster.
- Macrogol 4000-based products require larger doses to achieve the same effect.
Target Audience:
- Constipass: Suitable for children from 6 months of age.
- Macrogol 4000-based products: For children aged 8 and above.
Effect Time:
- Macrogol 3350 products: 1–4 hours.
- Macrogol 4000 products: 24–48 hours.
Constipass is safe for all users, including children, pregnant women, and breastfeeding mothers. The product is available in powder form with a pleasant taste, making it easy for children to take. Many parents report great results.

5. Novolax Product
When discussing constipation treatment, Novolax is a must-mention product.
Novolax contains natural soluble fiber. Upon entering the digestive system, Novolax doesn't dissolve in water but absorbs it, forming a gel-like mixture that increases volume, softens, and aerates stools. When it reaches the large intestine, it becomes food for beneficial gut bacteria, boosting the population of beneficial bacteria in the colon by 50 times. These beneficial bacteria ferment the soluble fiber in the colon, producing gases and byproducts such as short-chain fatty acids: lactic acid, acetic acid, various vitamins, and nutrients. It also creates a mildly acidic environment (pH~5.9), preventing harmful gut bacteria from growing, protecting the digestive system, and strengthening immunity by increasing beneficial bacteria levels.
This process helps reduce constipation effectively while nourishing the gut microbiome, promoting digestive health. Novolax is suitable for adults, children, pregnant women, and breastfeeding mothers.
Novolax has 2 variants:
- Novolax Drops specifically helps with constipation in children from 6 months old.
- Novolax Syrup is suitable for adults, pregnant and postpartum women, those with constipation-related hemorrhoids, and children from 1 year old.

- Polydextrose: 3000mg
- Plum juice powder: 150mg
