Gene Name PDE5A
Uniprot ID PDE5A_HUMAN
KEGG Pathway hsa:8654
Protein Family Cyclic nucleotide phosphodiesterase family
Protein Function
Plays a role in signal transduction by regulating the intracellular concentration of cyclic nucleotides. This phosphodiesterase catalyzes the specific hydrolysis of cGMP to 5'-GMP (PubMed:9714779, PubMed:15489334). Specifically regulates nitric-oxide-generated cGMP (PubMed:15489334).

  • Additive hypotensive effects by the combination of Vardenafil and Maraviroc 

Recommended Action
      Management Caution is advised when maraviroc is prescribed to patients on concomitant medications known to lower blood pressure. Close monitoring for development of hypotension is recommended. Ambulatory patients should be advised to avoid rising abruptly from a sitting or recumbent position and to notify their doctor if they experience dizziness, lightheadedness, syncope, orthostasis, or tachycardia.
