The pills are not active

In fact, there are pills that do not contain drugs inside but still have diagnostic and therapeutic effects.

Placebo

To determine whether a new drug (new treatment) is effective or not and how effective it must be through a clinical trial. Especially randomized controlled clinical trials.

Usually in a trial, volunteer patients will be divided into two or more groups. In particular, the group of patients treated with real medicine in many different doses. A group of patients taking placebo in the form and taste of the same medicine but did not contain any therapeutic substance.

To ensure objectivity, both doctors, nursing staff and patients who are dispensed with drugs are completely unaware (double blind therapy). Only independent experts have a list on hand to evaluate.

Endoscopic capsules

The strange thing is that placebo is effective in treating, reducing symptoms in some short-term cases that can only be explained by the psychological impact that the test participants have taken. There is also a theory that when taking a placebo, the patient's body secrete hormones Endorphin (endogenous drug), which has the same analgesic effect as opium.

Capsules against constipation

Capsule is very familiar to everyone and easy to swallow. At the 'Digestive Disease 2014 - DDW14' program , scientists introduced a type of anti-constipation pill that contained no drugs and was not a placebo.

This is the achievement of physical impulse application to treat constipation . After being swallowed by mouth, the pill will travel through the gastrointestinal tract for 6-8 hours to reach the position of the narrowed intestine or a point that needs action on the colon. Then, the capsule with the tiny inner motor will emit pulses, stimulate the intestinal tract to push the stool out.

The pilot study showed that impulse capsules doubled the number of weekly defecations for patients with idiopathic chronic constipation (CIC) and dominant constipation due to irritable bowel syndrome (C-IBS). . Science Daily quoted the medical doctor Yishai Ron as saying that although common constipation medication is widely used, up to 50% of patients are unhappy, possibly because of poor effectiveness or effectiveness. extra, not to mention safety issues when using long term.

Surveying 26 voluntary patients who used vibratory tablets twice a week, compared with traditional anti-constipation medications showed that constipation patients could increase the number of bowel movements from 2 to 4 times every week, reduce unpleasant symptoms and easier when expelling waste outside the body. Besides, there are few side effects for impulsive capsules.

With a pre-established program, after entering the gastrointestinal tract for 6-8 hours, the small motor inside the capsule will create mechanical stimuli that help move the stool through the digestive tract. Dr. Ron and his colleagues are entering a double-blind trial to continue exploring the potential of constipation-resistant pills that do not contain pharmaceuticals.

Endoscopic capsules

In recent years, developed countries have used a endoscopic technique that is almost painless, uncomfortable for patients, which are endoscopic capsules (Pill Cam) . The leading countries in Pill Cam techniques are the US, UK, Canada . and now it's Japan with Sayaka capsule . It is a small device containing a processor (CPU), camera to record video with 2 Mega Pixel resolution, illuminated by fluorescent lights and LED lights.

According to Popsi, after entering the patient's body, Sayaka will have 8 hours of wandering in every corner of the gastrointestinal tract to transmit the recorded image, and the doctor will diagnose it. Sayaka can move and rotate 360 ​​degrees, recording 30 images per second. After 8 hours of travel, it can record a total of 870,000 images, transmitted outside the body by radio waves like the wireless connection protocol of a computer.
