Activation inhibits the release of pain transmitters from the lateral cord, leading to hyperactivation of intrinsic factor, which binds to the U subtype opioid receptors and inhibits serotonin and norepinephrine, thereby eliminating the pain response.

By inhibiting phosphodiesterase in smooth muscle cells, blocking adenosine receptors, interfering with the movement of calcium ions in smooth muscle cells, and relaxing bronchial smooth muscles; inhibiting the release of various inflammatory mediators and cytokines, thereby controlling airway inflammation and reducing airway hyperresponsiveness.

Adapalene is a retinoid compound with anti-inflammatory properties. It binds to specific retinoic acid nuclear receptors to normalize the differentiation of hair follicle epithelial cells, reduce the formation of microacne, and relieve the inflammatory response of acne (such as pustules and papules).

Urapidil is a highly selective α1 receptor blocker with both peripheral and central effects. The peripheral vasodilator effect is mainly to block postsynaptic α1 receptors, which significantly reduces peripheral resistance. At the same time, it also has a moderate vasoconstrictor effect of blocking catecholamines. The central effect is to reduce blood pressure by stimulating serotonin-1A receptors and reducing the sympathetic feedback regulation of the medullary cardiovascular center. At the same time, it has no side effect of reflex heart rate acceleration and can also improve various hemodynamic indicators.

Bacampicillin is ampicillin methyl amyl ester, which has no antibacterial activity in vitro. During in vivo absorption, it is hydrolyzed into ampicillin by nonspecific esterases in the intestinal wall to exert its antibacterial effect. Ampicillin sodium is a broad-spectrum semi-synthetic penicillin. It is effective against a variety of Gram-positive and Gram-negative bacteria and exerts its bactericidal effect by inhibiting bacterial cell wall synthesis.
