This product is a mild peripheral vasodilator, which is gradually hydrolyzed into niacin and inositol in the body, so it has the pharmacological effects of both niacin and inositol, and has lipid-lowering effects. Its vasodilating effect is milder and more lasting than that of niacin, and it does not have side effects such as flushing and stomach discomfort after taking niacin. This product can selectively dilate blood vessels in lesions and sensitive areas stimulated by cold, while its dilating effect on normal blood vessels is weaker. In addition, it has the effects of dissolving blood clots, anticoagulation, anti-fatty liver, and reducing capillary fragility.

Tetracycline antibiotics are broad-spectrum antibacterial agents with bactericidal effects at high concentrations. They inhibit peptide chain growth and bacterial protein synthesis by binding to the A position of the 30S subunit of the bacterial ribosome. They are effective against a variety of pathogens such as Rickettsia, Mycoplasma, Chlamydia, atypical mycobacteria, and spirochetes. They are more effective against Gram-positive bacteria than Gram-negative bacteria, but enterococci are resistant. Long-term use leads to serious drug resistance, and there is cross-resistance with other tetracycline antibiotics. Animal experiments have confirmed teratogenicity and possible mutagenicity.

Increase liver blood flow, improve liver function, significantly increase the water content in bile, have a stronger choleretic effect than dehydrocholic acid, can relax the sphincter of Oddi, and lower blood cholesterol

By inhibiting cyclooxygenase, it selectively inhibits the synthesis of prostaglandins in the hypothalamic temperature regulation center, leading to peripheral vasodilation and sweating to achieve an antipyretic effect; by inhibiting the synthesis and release of prostaglandins, it increases the pain threshold and has an analgesic effect. It is a peripheral analgesic, weaker than aspirin, and is only effective for mild and moderate pain. This product has no obvious anti-inflammatory effect.

No specific pharmacological effects mentioned

It exerts antiplatelet and vasodilator effects by inhibiting the activity of phosphodiesterase in platelets and vascular smooth muscle, increasing the cAMP concentration in platelets and smooth muscle; inhibiting the initial and secondary platelet aggregation and release reactions induced by ADP, adrenaline, collagen and arachidonic acid; not interfering with the synthesis of vascular protective prostacyclin by vascular endothelial cells; for patients with chronic arterial occlusion, it can increase tissue blood flow in the foot and gastrocnemius muscles, increase the lower limb blood pressure index, increase skin blood flow and skin temperature of the limbs, and improve intermittent claudication.
