PRINCETON, N.J., Aug. 09, 2023 (GLOBE NEWSWIRE) -- Medunik USA (member of Duchesnay Pharmaceutical Group) is pleased to announce that an increasing number of Americans with certain urea cycle disorders (UCDs) now have access to Pheburane® (sodium phenylbutyrate) through a rapidly expanding network of key pharmacy benefit managers (PBMs), state Medicaid programs or Managed Medicaid plans.
Six state Medicaid programs, namely Texas, Oklahoma, North Dakota, Utah*, New Hampshire and New Mexico*, have now included Pheburane® on their Preferred Drug Lists as well as being included on California’s Contract Drug List with no prior authorization required. Pheburane® is also covered with preferred status at PBMs serving ~40% of covered individuals.
Pheburane® offers an affordable taste-masked treatment option for patients affected by certain UCDs, used along with a specific diet, at one-third of the cost of RAVICTI® (glycerol phenylbutyrate) and half the price of OLPRUVA™, the most recently launched UCD treatment (based on published pricing information). Pheburane® is not indicated for the treatment of acute hyperammonemia.
Pheburane® is an innovative, palatable formulation designed with a special coating to mask the awful taste of sodium phenylbutyrate (NaPB) which leads some patients to not being able to consistently or correctly take their non-taste-masked medication, resulting in life-threatening complications.
The most common side effects associated with sodium phenylbutyrate are menstrual dysfunction, decreased appetite, body odor and bad taste or taste aversion.1
“We are glad our efforts to bring Pheburane® to Americans with certain UCDs are coming to fruition.” said Tanya Carro, Executive Vice-President of Medunik USA. “The competitive price of Pheburane® combined with increasing coverage from public and private payers is a testimony of Medunik USA’s commitment to the UCD community and its stakeholders.”
UCDs are rare, chronic, genetic conditions that can be fatal if left untreated, and can impact children from the time of birth. UCDs disrupt the body’s urea cycle and, therefore, the body is unable to remove the dangerous buildup of toxic chemicals, particularly ammonia, that are created from the digestion of protein. One in 35,000 people in the United States or about 28 per one million residents suffer from UCDs of different levels of severity.2
Pheburane® consists of small oral pellets (about the size of sugar crystals) which are easily measured with its reusable, calibrated dosing spoon. It does not require any mixing or oral syringes and there is no weight restriction for patients. Pheburane® has a proven history in the global treatment of UCDs, as it has been available in Europe since 2013, and in Canada since 2015. Medunik USA has provided access to Pheburane® for Americans affected by certain UCDs since September 2022 and has since been working diligently at securing nation-wide coverage at a competitive price.
Medunik USA offers Pheburane® through its UNIK Support Program – designed to support each unique patient. UNIK offers specialized services including a copay savings program, patient care liaison services, mail order pharmacy and other support services. Visit Pheburane.com for more information.

About urea cycle disorders (UCDs)
The urea cycle is a process which allows the body to keep and use positive contents of food and filter and remove any toxic substances that can be ingested or created. UCDs are rare genetic disorders that cause errors in this process, allowing toxic substances to build up in the bloodstream, potentially to dangerous and fatal levels. The key marker for UCDs is high levels of ammonia. Removal of ammonia from the bloodstream normally occurs via its conversion to urea, which is then excreted by the kidneys. Ammonia is extremely toxic, particularly to the central nervous system. UCDs can cause catastrophic illness in newborns within 36 to 48 hours of birth despite the infants appearing normal, so they can be discharged from hospital before signs of UCDs develop. UCDs require lifelong monitoring and treatment.2
About Pheburane®
Pheburane® is a taste-masked oral formulation of sodium phenylbutyrate, approved by the Food and Drug Administration (FDA) as adjunctive therapy to standard of care, which includes dietary management, for the chronic management of adult and pediatric patients with UCDs, involving deficiencies of carbamylphosphate synthetase (CPS), ornithine transcarbamylase (OTC) or argininosuccinic acid synthetase (AS). Pheburane® is not indicated for the treatment of acute hyperammonemia.1
