|Alamast (Pemirolast Potassium) Controls Ocular Itching in Allergic Conjunctivitis |
FT. LAUDERDALE, FL -- May 8, 2000 -- Santen Pharmaceutical Co., Ltd. and Santen Inc. announced the results of new data on Alamast(TM) (pemirolast potassium ophthalmic solution) 0.1 percent. The studies, which included approximately 400 patients and were presented at the Association for Research in Vision and Ophthalmology (ARVO), were designed to assess the safety and efficacy of Alamast in preventing ocular signs and symptoms of allergic conjunctivitis.
These randomized, double-masked, parallel group studies demonstrated that Alamast was statistically significant versus placebo in preventing ocular itching in allergic conjunctivitis. "What was so unique about these studies," comments Dr. Adrienne Graves, Vice President of Worldwide Clinical Development, "was that patients were studied in a real-world environment (ragweed season) for up to 17 weeks." Dr. Graves went on to say that the results are clinically meaningful because, "they demonstrate that Alamast works all season long."
Alamast is a mast cell stabilizer that works by inhibiting the in vivo Type I immediate hypersensitivity reaction. It also inhibits the antigen- induced release of inflammatory mediators such as histamines and leukotrienes C4, D4, and E4 from human mast cells. Alamast also exhibits a third action of inhibiting the chemotaxis of eosinophils.
Alamast was not significantly different than placebo for adverse events, visual acuity, biomicroscopy and ophthalmoscopy findings, or IOP. The most commonly reported ocular adverse events were foreign body sensation (2 percent), burning/stinging (1 percent), dry eye (1 percent), and ocular discomfort (1 percent). Patients who wear soft contact lenses and whose eyes are not red should be instructed to wait at least 10 minutes after instilling Alamast before insertion of contact lenses.
"Alamast represents an important therapeutic agent for ocular allergy, particularly for patients who have known recurring allergies or who need prolonged treatment," states Jerry Hansen, President and CEO of Santen Inc. "We expect these positive results to add to the body of knowledge we have already accumulated on Alamast, helping to propel prescriber adoption when we launch the product this summer."
