Limaprost Alfadex Uses, Dosage, Side Effects, Food Interaction and all others data.

Limaprost Alfadex (as Limaprost Alfadex alfadex; CAS number 88852-12-4) is an oral prostaglandin E1 analog. Prostaglandins act on a variety of cells such as vascular smooth muscle cells causing constriction or dilation, on platelets causing aggregation or disaggregation and on spinal neurons causing pain. Prostaglandins have a wide variety of actions, including, but not limited to muscular constriction and mediation of inflammation. Limaprost Alfadex alfadex has been shown to improve peripheral circulatory failure with a vasodilator action and an antithrombotic effect. It also improves poor blood flow in the nerve tissue in cervical spondylosis and normalizes nerve function. Limaprost Alfadex alfadex was discovered from collaborative research between Ono Pharmaceutical (Ono) and Dainippon Sumitomo Pharma (DSP). It was approved for the treatment of ischemic symptoms such as skin ulcer, pain and coldness accompanying thromboangiitis obliterans in 1988; and for the treatment of subjective symptoms such as pain and numbness in the lower leg and walking disability associated with acquired lumbar spinal canal stenosis as an additional indication in 2001. The drug has been sold under the trade name of Opalmon® Tablets by Ono and Prorenal® Tablets by DSP. In 2011, Ono and DSP initiated Phase II clinical trials in Japan for the treatment of carpal tunnel syndrome. In 2013, these trials were discontinued because the study failed to demonstrate efficacy. Ono and DSP also discontinued the development of limaprost alfadex for the additional indication of cervical spondylosis in 2008 due to the failure to demonstrate the anticipated efficacy in a Phase II study in patients with the disease. However, it was verified by Seoul National University Hospital in November of 2014 that the study on the efficacy of oral limaprost alfadex after surgery for cervical myelopathy was still ongoing.

Limaprost Alfadex produces vasodilation to improve blood flow to the extremities and increase cutaneous temperature .

Uses

Limaprost Alfadex is an oral prostaglandin E1 analogue used to improve symptoms associated with thromboangiitis obliterans, acquired lumbar spinal canal stenosis, and other ischemic conditions.

Limaprost Alfadex is used for the improvement of various ischemic symptoms such as ulcer, pain and feeling of coldness associated with thromboangiitis obliterans as well as improvement of subjective symptoms (pain and numbness of lower legs) and gait ability associated with acquired lumbar spinal canal stenosis (in patients with bilateral intermittent claudication showing normal SLR test result).

Limaprost Alfadex is also used to associated treatment for these conditions: Ischemic Ulcers, Pain caused by Ischaemia, Thromboangiitis Obliterans

How Limaprost Alfadex works

As a prostglandin E1 analog, limaprost acts as an agonist at prostraglandin E2 receptors. It likely stimulates the adenylate cyclase coupled E2 subtype of these receptors to produce smooth muscle relaxation .
