Pharmacological action
This medicine is a specific smooth muscle antispasmodic drug, which has a relaxing effect on smooth muscles such as blood vessels, bronchi, gastrointestinal tract and biliary tract, and is used to relieve or prevent functional or neurological smooth muscle spasms. It has a selective blocking effect on cardiac beta receptors. The antispasmodic effect of this drug is many times stronger than that of papaverine, which also acts on smooth muscle, and the effect lasts longer. The drug only acts on smooth muscle and does not affect the autonomic nervous system, so it can be used in patients with glaucoma and benign prostatic hypertrophy for which anticholinergic antispasmodics are contraindicated

Applicable symptoms
Erectile dysfunction and pulmonary hypertension.
