Dr Ian Wilding chief executive, Pharmaceutical Profiles said recently that many candidate drug molecules currently being developed had complex chemistry, poor solubility and limited permeability, which led to problems of delivering the drugs effectively to patients.

Current status of capsule endoscopy through a whole digestive tract. The small electronic pill, when ingested by the patient, emits a signal during its entire transit through the GI tract. Latest views Mark Lyonette: Following the Enterion Capsule within the GI tract and locating its released cargo is easy using gamma scintigraphy provided the drug is suitably labeled.

An earthworm-like locomotive mechanism for capsule endoscopes. Around the camera lens, four white LEDs and magnetic coils for focus adjustment are placed[ 23 ]. In vivo trial of a driving system for a self-propelling capsule endoscope using a magnetic field with video. Self-stabilizing colonic capsule endoscopy: A feedback mechanism tells the operator if the triggering mechanism has been successful.

Currently, the major problem of all existing commercial capsule devices is the lack of control of movement. Robotic versus manual control in magnetic steering of an endoscopic capsule.


This is controlled by a single micro-motor and occupying a total volume of just mm 3. It is understood that the clinical performance of Check-Cap device is under investigation. With the new technology, which could test particulates and liquids, decisions on optimal drug delivery technology, or on whether the oral route was perhaps not suitable after all, could now be taken before too much time had been spent on formulation development.

Disease Management Disease Management covers the diseases commonly encountered in primary care by system, with common therapeutic issues.

Philips Research in Eindhoven, Netherlands, has developed a prototype called intelliCap[ 23738 ]. In order to maximize the diagnostic yield of CE, Gu et al[ 60 ] proposed recently an ingenious spherical device – called the MicroBall – with multiple six cameras Figure 8. Two tanks with valves are positioned in the center and a there is a capacitor to store electric power and a microwave video signal transmitter[ 2223 ].

For example in the developed prototype the axial magnetic attraction compresses a drug chamber between two internal magnets so as to release a drug through holes at a critical pressure.

As a consequence, decisions to accelerate capsuule terminate development of drug candidates can be made on the basis of sound scientific data. Corresponding Author of This Article.

A remote controlled drug delivery capsule for use in absorption studies has been developed by a UK company.

The major advantage of this platform is that no prior colon cleansing is needed, although the patient is still required to drink an oral contrast solution to label faecal material[ 7374 ]. The average percentages of the marker detection rate for unmodified capsule endoscopy, self-stabilizing capsule endoscopy, and colonoscopy, respectively, were Wireless endoscopy in Impression of movement while in the colon, with permission. The enterio is equipped with four actuators and clampers that mimic ebterion claws[ 79 ].


One of the major problems of the capsule platform for digestive endoscopy, especially when there entrrion no locomotion control is the adoption of the single-pole lens model; however, integrating multiple cameras has still problems with size and power consumption[ 20 ].

The first non-invasive, prep-free imaging test for colon cancer.

Formulation tech goes Enterion

The empty capsule is excreted. A prototype was developed to demonstrate how a camera-enabled wireless capsule endoscope can be enhanced with navigation capabilities by docking on it three capsules with angular and rotational servos acting like legs.

Towards a micropositioning system for targeted drug delivery capsulf wireless capsule endoscopy.

Enterion has the capability to deliver, through a 9-mm opening, any type of drug formulation including dry powder, semisolid, suspension or solution formulations when the spring is released, forcing a piston to move along the shaft of the capsule, thus, emptying capsile reservoir to specific locations of the GI tract[ 239 ]. Investigation of colonic and whole-gut transit with wireless motility capsule and radiopaque markers in constipation.

Latest Celebrating a year of career highlights 12 DEC What we have learned and what to expect from capsule endoscopy.

Researchers can then measure the extent to which the drug is absorbed from different regions of the GI tract. The overall clinical outcomes from the NEMO project are summarized[ 43 ].
