Product details
The antipyretic and analgesic effect of Phenacetin Powder is similar to that of "acetylsalicylic acid". Phenacetin Raw Materials is mainly used as antipyretic and analgesic, with slow and long-lasting effect, and it has a better efficacy in the treatment of headache, neuralgia, arthralgia, and fever etc. But the anti-rheumatic and anti-inflammatory effects are weaker.
The mild analgesic effect of Phenacetin CAS 62-44-2 can be maintained for 3-4 hours; the synergistic effect of combining with salicylic acid enhances the analgesic effect.
Uses and functions of Phenacetin Powder.
The antipyretic effect of finasteride is stronger than the analgesic effect. The strength of the drug is comparable to that of aspirin, with a slow and long-lasting effect and low toxicity. Studies have shown that both the product and its metabolite paracetamol have antipyretic effects.
Because with enzyme inhibitors so that finasteride can not be converted to paracetamol, can still show significant antipyretic effect. Therefore, the antipyretic effect that occurs after administration of the product is not only produced by its active product paracetamol.

After the reaction is completed and the reactants are cooled, fenadine is precipitated, filtered, washed with cold benzene and dried to obtain the product, with a yield of 86% of the theoretical amount.
