Abstract:
Although substantial advances have been achieved in recent decades in the clinical management of heart diseases, new therapies that provide better or additional efficacy with minimal adverse effects are urgently required. Evidence that has accumulated since the 1990s indicates that the peptide hormone relaxin has multiple beneficial actions in the cardiovascular system under pathological conditions and, therefore, holds promise as a novel therapeutic intervention. Clinical trials for heart failure therapy using relaxin revealed several beneficial actions. Here we review findings from mechanistic and applied research in this field, comment on the outcomes of recent phase I/II clinical trails on patients with heart failure, and highlight settings of cardiovascular diseases where relaxin might be effective.

Centrally Acting Muscle Relaxants: Therapeutic Uses
Centrally acting drugs are classified into spasmolytic and antispasmodic drugs. Spasmolytic drugs such as baclofen, diazepam, and tizanidine inhibit spinal motor neurons and decrease muscle tone. Spasmolytic drugs are administered for severe and chronic spasms due to multiple sclerosis, cerebral palsy, stroke, and spinal cord and muscle injuries. However,...

Relaxation of Skeletal Muscles
When an action potential reaches the axon terminal, it depolarizes the membrane and opens voltage-gated sodium channels. Sodium ions enter the cell, further depolarizing the presynaptic membrane. This depolarization causes voltage-gated calcium channels to open.
