It has a direct relaxant effect on the smooth muscles of the respiratory tract; partly by inhibiting phosphodiesterase to increase the intracellular cAMP content; partly due to the release of endogenous adrenaline and norepinephrine; as a purine receptor blocker, it can counteract the contractile effect of adenine and other substances on the respiratory tract; it enhances the contractility of the diaphragm and improves respiratory function.

This product is a fluoroquinolone antibacterial drug with a broad-spectrum antibacterial effect, especially against aerobic Gram-negative bacteria. It acts on the A subunit of bacterial DNA helicase, inhibits DNA synthesis and replication, and causes bacterial death. It has effects on both Gram-positive and Gram-negative bacteria. Bacteria are not easy to develop resistance to this product, and there is no cross-resistance between similar drugs and antibiotics.

Iron is a component of hemoglobin in red blood cells. When iron is deficient, the amount of hemoglobin synthesized by red blood cells decreases, causing the red blood cells to become smaller and their oxygen-carrying capacity to decrease, resulting in iron-deficiency anemia. Oral administration of this product can supplement iron and correct iron-deficiency anemia.
