Lactulose

The Generic name of this drug

Treatment Summary

Lactulose is a synthetic sugar used to treat constipation and portal-systemic encephalopathy (PSE). It was developed in 1929, but its use as a laxative wasn’t discovered until the 1960s. It was approved by the FDA in 1977 and is now available without a prescription. It is on the World Health Organization’s List of Essential Medicines as one of the most effective and safe medicines. While it is an option for treating constipation, it is not clear how effective it is for treating PSE, since it is unethical to withhold it from patients in a placebo study.

Effectiveness

How Constulose Affects Patients

Lactulose is most often taken as a pill or enema. It doesn't absorb into the body, so it stays in the gut and produces its effects there. The main effects are increased stool amounts and softer stools, which can cause bloatedness, belching, frequent passing of gas, and diarrhea.

How Constulose works in the body

Lactulose is a synthetic sugar that helps with constipation and portal-systemic encephalopathy (PSE). When it is broken down by bacteria in the large intestine, it creates organic acids and small amounts of formic and acetic acids. These acids increase the water content in your stool, making it softer. This laxative effect usually takes 24 to 48 hours to become apparent. At the same time, it also makes the colon more acidic, which helps to treat PSE. This acidic environment prevents ammonia from being absorbed back into the body. It also kills off bacteria that produce ammonia, which further reduces the amount of

Constulose Toxicity & Overdose Risk

The toxic dose of lactulose for mice has been found to be 48.8 mL/kg and more than 30 mL/kg in rats. Taking too much lactulose may cause stomach cramps and diarrhea, so it is important to replace lost fluids and electrolytes. Although there is no evidence that lactulose affects fertility in animals, it has not been studied in pregnant or breastfeeding women, so use with caution. There is also limited data regarding the safety and efficacy of lactulose in children. The long-term effects of lactulose on mutagenic potential or cancer risk in humans are unknown.

Constulose for Incomplete or Infrequent Bowel Movements

This treatment has been very effective for me. I take it because I'm on narcotic pain medication, and it's helped my liver problems a lot. It tastes good and I use it with magnesium sulfate. I drink one gallon of water per day to keep everything working correctly, and I'm really happy with the results.

Constulose for High Amount of Ammonium in the Blood

After my gallbladder removal, I was really struggling. So I spoke with my doctor and he prescribed me this medication. He said to not eat for 24 hours and drink lots of water, and take the medicine every two hours. And after just the second dose, I was feeling so much better!

Constulose for Incomplete or Infrequent Bowel Movements

Lactulose has been extremely effective for my five-year-old twins. They have a bowel movement at least once or twice daily, and their stools are neither hard nor mushy. I highly recommend that people suffering from similar problems ask their doctor about this treatment option.

Weizmannia Coagulans for Gut Health

18 - 50
All Sexes
Saint Charles, MO

This study will evaluate the effects of supplementation with Weizmannia (Bacillus) coagulans JBI-YZ6.3 on gastrointestinal health in healthy, physically active adults. The primary objective is to determine whether daily intake of this probiotic strain improves symptoms of constipation and related gastrointestinal function compared with placebo. Approximately 30 healthy men and women aged 18 to 50 years will be enrolled in a randomized, double-blind, placebo-controlled, crossover trial. Participants will complete two 4-week supplementation periods, one with Weizmannia (Bacillus) coagulans JBI-YZ6.3 and one with placebo, separated by a 4-week washout period. The total duration of participation will be approximately 13 to 14 weeks, including screening and testing visits. Gastrointestinal symptoms will be assessed at baseline and after each supplementation period using validated questionnaires, with particular focus on the constipation domain of the Gastrointestinal Symptom Rating Scale (GSRS). Secondary outcomes will include additional gastrointestinal symptom domains and markers of perceived gut comfort and function. This study is designed to determine whether supplementation with Weizmannia (Bacillus) coagulans JBI-YZ6.3 produces clinically meaningful improvements in gastrointestinal symptoms in physically active adults compared with placebo.

Dexmedetomidine + Dexamethasone for Postoperative Pain

18 - 75
All Sexes
Tucson, AZ

The goal of this clinical study is to improve upon the standard practice of utilizing nerve blocks to enhance the satisfaction of patients undergoing shoulder, or foot and ankle surgery regarding their quality of pain control, the duration of their nerve blocks, as well as the avoidance of opioid medications and subsequently their undesirable side effects. The researchers hypothesize that dexmedetomidine and dexamethasone (Dex-Dex) will work synergistically as adjuncts in a low, non-weight based formula. This would allow the investigators to improve patient satisfaction by providing them with a superior means of pain control that is longer in duration with a decreased probability of unwanted side effects. The proposed clinical study will be a prospective, randomized control trial.

Kiwifruit Extract for Constipation in Children

4 - 17
All Sexes
Hamilton, Canada

The goal of this pilot feasibility randomized controlled trial is to determine whether Actazin (kiwifruit extract) is a feasible and effective alternative to polyethylene glycol 3350 (PEG 3350) for maintenance therapy in children with functional constipation (FC). This study will include children aged 4 to 17 years who meet the Rome IV criteria for functional constipation. The main questions it aims to answer are: 1. Is it feasible to conduct a definitive, multi-centre trial comparing Actazin to PEG 3350 in children with FC? 2. What are the within-group differences in clinical outcomes such as stool frequency, abdominal pain, and laxative use over a 4-week period? Researchers will compare chewable Actazin tablets with placebo PEG 3350 powder to PEG 3350 powder with placebo Actazin tablets to see if Actazin is a viable non-pharmacologic natural health product alternative for treating FC. Participants will: Undergo an initial bowel cleanout using PEG 3350 and bisacodyl. Following, they will be randomized to one of two groups: 1. Actazin chewable tablets (titrate to effect: 600-2400 mg/day) + placebo PEG 3350 2. PEG 3350 (dose based on age and titratable to effect) + placebo Actazin chewable tablets Participants will take the assigned intervention daily for 4 weeks and complete a daily bowel diary recording stool frequency, consistency (Bristol Stool Scale), abdominal pain, and laxative use. They will have weekly follow-ups via phone or electronic survey to assess adherence, medication use, and adverse events. Additionally, a bi-weekly follow-up will be conducted for an additional 8 weeks to track longer-term outcomes. Outcomes: Primary feasibility outcomes include consent rate, adherence to allocated intervention, and 4-week follow-up completion rate. Secondary clinical outcomes include resolution of FC (Rome IV criteria), weekly stool frequency, abdominal pain episodes, use of rescue laxatives, and treatment palatability. This study is being conducted at McMaster Children's Hospital and is funded by the Hamilton Academic Health Sciences Organization (HAHSO). Data collection will be managed using the Lumedi™ platform, and safety will be overseen by a Data Safety Monitoring Board (DSMB).

Pelvic Health Rehabilitation for Breast and Gynecologic Cancer

18+
Female
Edmonton, Canada

The GYVE study aims at testing an online program (eModule) to help people who have had breast or gynecologic cancer and are experiencing pelvic health issues like urinary incontinence and pain during sex. These cancers and their treatments can cause significant pelvic health problems, affecting daily life and quality of life. Physiotherapy can help, but access is often limited due to costs and other barriers. The study will involve 20 participants from Quebec and Edmonton, who will take part in a 12-week program with weekly online group sessions led by a physiotherapist. Topics include pelvic floor muscle training, use of vaginal moisturizers, hydration, diet, and pain management. Led by experts in cancer rehabilitation and pelvic health, the study aims to provide valuable information on the feasibility and effectiveness of the eModule, potentially leading to broader implementation to help more people with lived experience of cancer.
