The US Food and Drug Administration (FDA) has approved the first generic version of a commonly used inhaler, marketed as Proventil, and the anti-parasitic Daraprim, which has previously been the subject of a price gouging scandal.
FDA approves Proventil and Daraprim generics

Pyrimethamine, which is sold under the brand-name Daraprim, is a treatment for parasitic diseases including toxoplasmosis, which may affect up to half of the global population. It is caused by the parasite Toxoplasma gondii, which can be contracted by eating undercooked meat, drinking contaminated water, or through contact with an infected cat.
Although toxoplasmosis is often asymptomatic, some people can experience a flu-like illness and the immuno-compromised may experience more severe symptoms, such as seizures. Severe symptoms are also more likely in pregnant women. It is considered the leading cause of death from foodborne illness in the US.
Daraprim, which is taken orally, is on the World Health Organization’s (WHO) List of Essential Medicines. Despite its essential nature, the manufacturer Turing Pharmaceuticals increased the price of the treatment from US$13.50 to US$750 a tablet in 2015 – a 50-fold increase . Even after the drug lost its patent, Turing (later renamed to Phonexius) maintained their monopoly on the drug.
This looks set to change as on 28 February 2020, FDA announced approval of the first generic version of the drug, which will be produced by New York-based company Cerovene.
FDA says its Drug Competition Action Plan aims to remove barriers to generic drug development and remove loopholes that have allowed brand-name drug companies to ‘game’ the rules in order to delay generics competition, such as preventing generics makers from obtaining drug samples. The agency posted a list of all drugs where this was a problem, which included Daraprim.
Commissioner Stephen M Hahn said in a statement: ‘Empowering patients and promoting choice and competition are top priorities for FDA. These important efforts include improving access to safe, effective and high-quality generic medications. Today’s approval is especially important for populations that are more susceptible to toxoplasmosis infections, such as pregnant women and individuals with HIV or AIDS by paving the way for more choices in treatment options’.
Following this, in April 2020 the Agency announced the first approval for a generic version of Proventil (albuterol), an inhaler used to open the airways in patients with asthma and chronic obstructive pulmonary disease (COPD). It is also on WHO’s List of Essential Medicines. Costs for a month’s supply in the US ranged between US$25 and US$50 in 2015.
The generic drug is approved at a 90 mcg/inhalation dosage and is produced by Indian manufacturer Cipla Ltd. Commissioner Hahn said the approval was important given the increased demand for albuterol during the coronavirus pandemic.
‘We remain deeply committed to facilitating access to medical products to help address critical needs of the American public’, he added.
