Documented Uses

For the treatment of pneumonia due to <i>Pneumocystis carinii</i>.
Pentamidine isethionate is an antifungal prescription medicine approved by the U.S. Food and Drug Administration (FDA) for the treatment and prevention of Pneumocystis pneumonia (PCP). The FDA-approved uses for pentamidine isethionate depend on the dosage form of the drug. Specifically, pentamidine isethionate injection is approved to treat PCP, and pentamidine isethionate inhalant is approved to prevent PCP in people with HIV who are at high risk of developing PCP.
PCP can be an opportunistic infection (OI) of HIV.
Substances that destroy fungi by suppressing their ability to grow or reproduce. They differ from FUNGICIDES, INDUSTRIAL because they defend against fungi present in human or animal tissues.
Substances that are destructive to protozoans.
Agents destructive to the protozoal organisms belonging to the suborder TRYPANOSOMATINA.
