Phosphodiesterase Enzyme Inhibitors Market - Industry Analysis, Size, Share, Growth, Trends and Forecast to 2024

Phosphodiesterase are a diverse family of enzymes (11 isoenzymes) that play a key role in regulating intracellular levels of secondary messengers - cyclic adenosine monophosphate (cAMP) and cyclic guanosine monophosphate. These enzymes identified to be pharmacologically active in the 1950s, hydrolyses cyclic nucleotides to treat various diseases such as cardiovascular, respiratory and erectile dysfunction. Distinct distribution of all the types of isoenzymes has provided possibilities for selective target therapies.
