      Drug Name Milrinone Maraviroc
      Mechanism 1 Hypotensive effects
Phosphodiesterase 3  Inhibitor
Antihypertensive agent
      Key Mechanism Factor 1
Factor Name Phosphodiesterase 3 Structure Sequence
Protein Family Cyclic nucleotide phosphodiesterase family
Protein Function
Cyclic nucleotide phosphodiesterase with specificity for the second messengers cAMP and cGMP, which are key regulators of many important physiological processes (PubMed:1315035, PubMed:8695850, PubMed:8155697, PubMed:25961942). Has also activity toward cUMP (PubMed:27975297). Independently of its catalytic activity it is part of an E2/17beta-estradiol-induced pro-apoptotic signaling pathway. E2 stabilizes the PDE3A/SLFN12 complex in the cytosol, promoting the dephosphorylation of SLFN12 and activating its pro-apoptotic ribosomal RNA/rRNA ribonuclease activity. This apoptotic pathway might be relevant in tissues with high concentration of E2 and be for instance involved in placenta remodeling (PubMed:31420216, PubMed:34707099).

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.
