CONRAY Solution for injection Ref.[10334] Active ingredients: Iotalamic acid

Conray is a sterile aqueous solution intended for use as a diagnostic radiopaque medium. Conray contains 60% w/v iothalamate meglumine, which is 1-deoxy-1-(methylamino)-D-glucitol 5-acetamido-2,4,6 triiodo-N-methylisophthalamate (salt), and has the following structural formula:

Each milliliter contains 600 mg of iothalamate meglumine, 0.09 mg edetate calcium disodium as a stabilizer and 0.125 mg of monobasic sodium phosphate as a buffer. The solution provides 28.2% (282 mg/mL) organically bound iodine. Conray has an osmolarity of approximately 1000 mOsmol per liter, an osmolality of approximately 1400 mOsmol per kilogram and is, therefore, hypertonic under conditions of use. The viscosity (cps) is approximately 6 at 25°C and 4 at 37°C. The pH is 6.5 to 7.7.

Conray is a clear solution containing no undissolved solids. Crystallization does not occur at normal room temperatures. It is supplied in containers from which the air has been displaced by nitrogen.
