Taiho Pharmaceutical to Launch Zenol Diclodirect

Penetrates Directly into Painful Shoulders and Lower Back To Go on Sale Nationwide on September 13, 2018

Taiho Pharmaceutical Co., Ltd. announced today the launch of Zenol Diclodirect (second-class OTC drug), containing diclofenac sodium, as a new addition to its Zenol series of topical analgesic anti-inflammatory products throughout Japan today

  • Details will be available soon at the Zenol Diclodirect multilingual brand site.

Zenol Diclodirect is the first product in the Zenol series to contain diclofenac sodium (1.0%) as an active ingredient. Diclofenac sodium shows an analgesic effect by inhibiting the production of prostaglandins, which are one of the substances that cause pain. Diclofenac-containing drug products have been growing in the market for topical analgesic anti-inflammatory medications in recent years (source: INTAGE SDI topical analgesic anti-inflammatory drug sales volume for 2013 – 2017).

Zenol Diclodirect provides relief by penetrating directly into painful shoulders and lower back. It is recommended for people with stiff shoulders and lower back pain caused by daily work and exercise.

Moreover, as the product is a hard gel in stick form, it is easily applied not only to the shoulders and lower back but also to affected areas that bend such as the neck and joints. It is convenient on the go, as it can be carried around without concern for liquid or ointment leakage.

Taiho Pharmaceutical will continue striving to improve human health and contribute to a society enriched by smiles.
