Why does topical analgesic ointment have a good analgesic effect? How does this ointment reduce pain? This article will give you an in-depth discussion of the scientific principles of topical analgesic ointment.
Skin absorption – The active ingredients in the ointment can be absorbed into the bloodstream through the skin, reaching the painful area to exert an analgesic effect. The rate of absorption depends on the nature of the drug and the added penetration enhancer.
Covering effect – the ointment forms a barrier film to protect against contact with the painful environment.
Hot and cold effect – Ointments containing natural ingredients such as mint and camphor stimulate the skin through hot and cold, affecting nerve conduction and blocking pain sensation.
Analgesic mechanism – Some ointments contain non-steroidal anti-inflammatory drugs, which can inhibit the release of inflammatory mediators to achieve anti-inflammatory analgesia.

Local anesthesia – Ointments containing compounds such as lidocaine provide temporary local anesthesia by blocking nerve conduction.
Enhance blood flow – Certain ingredients can promote blood circulation, accelerate the removal of inflammatory pain mediators, and reduce pain.
in conclusion:
Modern pharmaceutical technology allows us to develop a wide variety of external analgesic ointments, which achieve rapid and effective analgesic effects through skin absorption, protective film construction, stimulation and other mechanisms.
