Pharmacology
- Indication
Conray is indicated for use in excretory urography, cerebral angiography, peripheral arteriography, venography, arthrography, direct cholangiography, endoscopic retrograde cholangiopancreatography, contrast enhancement of computed tomographic brain images, cranial computerized angiotomography, intravenous digital subtraction angiography and arterial digital subtraction angiography. Conray may also be used for enhancement of computed tomographic scans performed for detection and evaluation of lesions in the liver, pancreas, kidneys, abdominal aorta, mediastinum, abdominal cavity and retroperitoneal space.
- Associated Conditions
- Pharmacodynamics
- Not Available
- Mechanism of action
- Not Available
- Absorption
Renal accumulation is sufficiently rapid that maximum radiographic density in the calyces and pelves occurs, in most instances, about 3 to 8 minutes after injection. In patients with impaired renal function, diagnostic opacification frequently is achieved only after prolonged periods.
- Volume of distribution
- Not Available
- Protein binding
Iothalamate salts are poorly bound to serum albumin.
- Metabolism
- Not Available
- Route of elimination
Following intravascular injection, Conray is rapidly transported through the circulatory system to the kidneys and is excreted unchanged in the urine by glomerular filtration. The liver and small intestine provide the major alternate route of excretion. In patients with severe renal impairment, the excretion of this contrast medium through the gallbladder and into the small intestine sharply increases.
- Half life
In patients with normal renal function, the alpha and beta half-lives of Conray were approximately 10 and 90 minutes, respectively.

Interactions
- Drug Interactions
Drug Interaction Acetaminophen Acetaminophen may decrease the excretion rate of Iothalamic acid which could result in a higher serum level. Acetylsalicylic acid Acetylsalicylic acid may decrease the excretion rate of Iothalamic acid which could result in a higher serum level. Alprazolam Alprazolam may decrease the excretion rate of Iothalamic acid which could result in a higher serum level. Amiloride Amiloride may increase the excretion rate of Iothalamic acid which could result in a lower serum level and potentially a reduction in efficacy. Amitriptyline Iothalamic acid may decrease the excretion rate of Amitriptyline which could result in a higher serum level. Amlodipine Amlodipine may decrease the excretion rate of Iothalamic acid which could result in a higher serum level. Amoxicillin Amoxicillin may decrease the excretion rate of Iothalamic acid which could result in a higher serum level. Amphetamine Amphetamine may decrease the excretion rate of Iothalamic acid which could result in a higher serum level. Ampicillin Ampicillin may decrease the excretion rate of Iothalamic acid which could result in a higher serum level. Auranofin Auranofin may decrease the excretion rate of Iothalamic acid which could result in a higher serum level. - Food Interactions
