SDP

Tiotropium bromide is a muscarinic acetylcholine receptor (mAChR) antagonist that blocks the binding of the acetylcholine ligand and subsequent opening of the ligand-gated ion channel. It is a 24-hour, anticholinergic bronchodilator used in the management of chronic obstructive pulmonary disease. It improves symptoms of chronic obstructive pulmonary disease complicated by chronic heart failure.

  • Targets mAChR
  • Involved in GPCR/G Protein and neuronal signaling pathways
  • Long-acting, stops signaling between neurons and leads to muscle relaxation
  • Used in the management of chronic obstructive pulmonary disease
  • Improves symptoms of chronic obstructive pulmonary disease complicated by chronic heart failure
