Sucroferric oxyhydroxide, sold under the brand name Velphoro, is a non-calcium, iron-based phosphate binder used for the control of serum phosphorus levels in adults with chronic kidney disease (CKD) on haemodialysis (HD) or peritoneal dialysis (PD). It is used in form of chewable tablets.Sucroferric oxyhydroxide is also known as a mixture of polynuclear iron(III)-oxyhydroxide, sucrose and starches.The most common side effects include diarrhea and discolored feces, which may become less frequent with continued treatment.It was approved for medical use in the United States in November 2013, and in the European Union in August 2014. Medical uses
Sucroferric oxyhydroxide is approved by the U.S. Food and Drug Administration (FDA) and the European Medicines Agency (EMA) for the control of serum phosphorus levels in patients with chronic kidney disease (CKD) on dialysis. Adverse effects
The most frequently reported adverse drug reactions reported from trials were diarrhoea and discoloured faeces. The vast majority of gastrointestinal adverse events occurred early during treatment and abated with time under continued dosing. Interactions
Drug-interaction studies and post hoc analyses of Phase III studies showed no clinically relevant interaction of sucroferric oxyhydroxide with the systemic exposures to losartan, furosemide, omeprazole, digoxin, and warfarin, the lipid-lowering effects of statins, and oral vitamin D receptor agonists. According to the European label (Summary of Product Characteristics), medicinal products that are known to interact with iron (e.g. doxycycline) or have the potential to interact with Velphoro should be administered at least one hour before or two hours after Velphoro.
Glycerol phenylbutyrate (USAN), trade name  Ravicti, is a medication used in the treatment of certain inborn urea cycle disorders. The medication works by preventing the harmful buildup of ammonia in the body. It is an FDA-approved prescription drug in the US. It is approved for anyone over 2 months of age. It was developed by Hyperion Therapeutics based on the existing drug Buphenyl, and received approval on February 1, 2013. Hyperion has been criticized for setting a high price for the drug. The price was set at US$250,000–290,000. In 2014, the drug generated $30.8 million in net sales, far behind the older and less expensive Buphenyl ($113.6 million in sales). In March 2015, Horizon Pharma acquired Hyperion Therapeutics and thus Raviciti. References
