Contrast Media Manufacturing Company

For the purpose of medical imaging, a certain substance is introduced into the
human body to change the image contrast of local tissues of the body. This
introduced substance is Contrast Media, also known as Contrast Agents. As the
first Contrast Media manufacturer in China, Beilu Pharma launched the domestic
MRI Contrast Media Gadopentetate Dimeglumine Injection in 1992, which broke the
foreign products monopoly and filled the domestic gap. As a well-known contrast
media manufacturing companies, we could provide a broad portfolio stems
Contrast Media across CT/X-ray and MRI modalities, and own the EU standard
manufacturing facilities.

Types of Contrast Media in Beilu Pharma

Magnetic Resonance Imaging (MRI)Contrast Media is Gadolinium based contrast
agent(GBCA). It is an intravenous injection, mainly used to enhance the image
quality of internal organs, blood vessels and tissues during MRI examinations.
GBCA contains gadolinium, which is connected to each other through carrier
molecules to form a chelating agent. According to the different chemical
structures, this contrast medium can be divided into two categories: linear and
macrocyclic. The linear structure of the imaging agents is easier to release
gadolinium ions, and the macrocyclic structure of the contrast material is more
stable and less likely to release gadolinium ions.

CT/X-RAY CONTRAST MEDIA

Iodine-containing Contrast Media is one of the common imaging contrast agents
used in radiology diagnosis and interventional therapy. It is also a basic
diagnosis drug for cardiovascular imaging under X-ray. Currently, the iodinated
Contrast Media used for cardiovascular system CT and digital subtraction
angiography are all water-soluble organic iodinated contrast materials.

Comparison of physicochemical characteristics of commonly used Contrast Media

Contrast media
(Concentration：mg（I）/ml) Osmotic pressure
(mOsm/kg water） Viscosity
（cP，37℃）
Iopamidol 300 616 4.7
Ioverol 300 651 5.5
Iohexol 300 672 6.3
Iobitridol 300 695 6
Iodixanol 320 290 11.8

The osmotic pressure of normal people is about 290-300mOsm/kg.

Taking the viscosity of water as 1, when the temperature is 37℃, the relative
viscosity of whole blood is 4-5, and the relative viscosity of plasma is 1.6-
2.4.

Three factors of renal injury induced by Contrast Media: Osmotic pressure,
Viscosity and the total iodine. Reduced iodine intake is a feasible strategy to
avoid kidney damage.
