Ingelheim/Germany 22 June 2005 – Boehringer Ingelheim today announced the launch of a new prolonged release tablet formulation of tamsulosin, its well established treatment for Lower Urinary Tract Symptoms (LUTS) due to benign prostatic hyperplasia (BPH). The new tablet formulation is based on an Oral Control Absorption System (OCAS®)* technology which provides for more consistent 24-hour drug release with reduced peak plasma concentration of tamsulosin.

As of April 15th,2005, this new small film-coated tablet will be marketed as Alna®OCAS® 0.4 mg in Germany. Other European Countries will follow in the market in the next months under the trademarks of Pradif® T (Greece, Italy, Portugal, Switzerland) and Urolosin® OCAS® (Spain). Launches in additional countries are anticipated in the future.

In placebo-controlled randomized pivotal trials Alna®OCAS® 0.4 mg tablet once daily has shown the well established efficacy of the current tamsulosin capsule while demonstrating placebo-like tolerability1,2.

One of the most bothersome symptoms in BPH patients which severely impacts the patient’s sleep and overall quality of life is frequent night-time urination (nocturia) 3. A recent placebo controlled study in BPH patients suffering from nocturia confirmed that the consistent 24-hour plasma concentration of Alna®OCAS® 0.4 mg tablet was associated with significant daytime and night-time symptom relief and significant improvement in quality of life4.

Unlike the tamsulosin capsule which must be taken after meals5, the new Alna®OCAS® tablet can be dosed independent of food intake. This advantage was confirmed in a study in the elderly comparing tamsulosin capsule and the new tablet under fasting conditions, where the use of the tablet was associated with smoother plasma concentrations and a lower incidence of blood pressure changes (orthostatic hypotension)6.

”Tamsulosin is one of the best tolerated alpha-blockers currently available for the treatment of BPH. The new Alna®OCAS® tablet, with its improved pharmacokinetic profile, represents a further treatment advancement in terms of patient convenience and for some patients offers the potential for even better tolerability” stated Prof. Martin Michel, leading expert in clinical pharmacology, Head of the Department of Pharmacology and Pharmacotherapy, University of Amsterdam, Netherlands.

Boehringer Ingelheim will continue to market Tamsulosin 0,4 mg capsules under the well-known tradenames FLOMAX®, ALNA®, JOSIR®, PRADIF®, SECOTEX® and UROLOSIN®.
