Pentamidine price?

Why does Pentamidine cost so much?

Pentamidine is a medication used to treat and prevent pneumocystis pneumonia (PCP), a type of lung infection that can be life-threatening for people with weakened immune systems, particularly those with HIV/AIDS [1]. The high cost of Pentamidine is largely due to its exclusivity under patent, which limits the availability of generic versions and increases prices [2].

How much does generic Pentamidine cost?

Although there isn't a widely available generic version of Pentamidine, the patent for the original formulation, Pentamidine Isethionate injection, is set to expire in the United States in 2026 [3]. This could lead to the entry of generic versions and potentially lower prices.

Pricing and accessibility in different countries

Pentamidine prices vary significantly across different countries. In the United States, the retail price of Pentamidine Isethionate injection can exceed $1,000 per vial, making it one of the most expensive antibiotics on the market [4]. In contrast, in some developing countries, Pentamidine may be available for significantly lower prices, often due to government subsidies or non-profit programs.

What alternatives to Pentamidine exist?

For people with HIV/AIDS who cannot take Pentamidine due to side effects or other issues, alternative treatments such as sulfamethoxazole-trimethoprim (SMX-TMP) or atovaquone-proguanil may be recommended [5].

When can we expect lower prices?

The patent expiration for Pentamidine Isethionate injection in the United States is expected to occur in 2026, which could lead to the entry of generic versions and lower prices. However, even after the patent expires, the price of Pentamidine may not necessarily decrease, as manufacturers may continue to charge high prices for their branded versions.
