Nippon Gases Italia S.r.l. acquired a majority of the share of the Spanish medical equipment manufacturer Noxtec Development SL. This will enable the two companies to work together on technological improvements of medical equipment used for nitrous oxide treatment. Nitrous oxide has a vasodilatory effect in cardiopulmonary blood vessels, and is currently used to treat pulmonary hypertension. The inhaled nitric oxide therapy market is expected to grow going forward. Both companies have a high level of technology and knowledge related to medical equipment development and medical gases, which they will combine in an effort to further improve the quality of medical equipment and services.
