Hyoscine N-Butyl Bromide is the Active Pharmaceutical Ingredient (API) present in anti-spasmodic treatments for abdominal pain. It brings fast pain relief for stomach cramps caused by diarrhoea , irritable bowel syndrome, and other gastrointestinal diseases, especially lower abdominal pain. It can also help ease bladder cramps and period pain.

What is a chronic gastrointestinal disease? Is it preventable?

Most gastrointestinal disorders (Cleveland Clinic) can be prevented by making a few lifestyle changes. Eat healthy, cook in a hygienic environment, and drink plenty of clean water. To minimise the risks, exercise at least thrice weekly, eat your greens for fibre to regularise your bowel movements and undergo a colonoscopy or cancer screening.

Is Hyoscine N-Butyl Bromide (HBB) a tablet or injection?

Hyoscine N-Butyl Bromide is available in solid dose as well as in the liquid form. However, the application of HBB in oral form has been gaining traction for the past six years, due to an increase in sales of the brand name, Buscopan. Worldwide sales of Hyoscine-N-Butyl Bromide in solid dosage is steadily increasing at 4% CAGR since 2013 and expected to reach 4.6% by 2027 (Fact.MR).

What is Buscopan and its uses?

When is the best time for a colonoscopy?

People with an average risk should get a colonoscopy done by age 50. If you have a family history of colorectal cancer or polyps, it is wise to get a colonoscopy at a younger age. Generally, colonoscopy is best 10 years younger than the affected family member’s age.
