Possible Impurities in Synthetic Flurophlogopite. View larger version Synthetic fluorphlogopite is not soluble in water. 15 In a test of the solubility of the ions in distilled water, magnesium, aluminum, and potassium were present at <5 × 10 −6, <5 × 10 −5, and <5 × 10 −4 g/L, respectively, after stirring for up to 72 hours at 30°C.

When iron sucrose was administered at deliberate overdoses to rabbit dams (up to 215 mg/kg/day) marked fetal/placental iron overload was noted. It is unlikely that significant fetal iron overload would occur in iron deficient pregnant women receiving therapeutic doses of VENOFER to correct iron deficiency (see General).

Structure elucidation of pharmaceutical impurities is an important part of the drug product development process. Impurities can have unwanted pharmacological or toxicological effects that seriously impact product quality and patient safety. This review focuses on current analytical strategies for chemical and structural identification of pharmaceutical impurities.

Sucrose is major constituent in some drugs also. Sucralfate (aluminium salt of sucrose octasulphate) is used in treatment of peptic and stomach ulcers [19]. Sucrose polyesters have also been used as contrast agents in magnetic resonance imaging (MRI) [20]. Sucrose forms at least 80% part of drug in iron sucrose which is marketed under the brand

Organic volatile impurities (OVIs) can result from the manufacture of active pharmaceuticals or other drug products.
