The level of connection between phosphodiesterase (PDE)-4 inhibitors and lung cancer will be discussed based on current studies. Phosphodiesterase 4 (PDE4) is a major cyclic adenosine-3′,5′-monophosphate-metabolizing enzyme in immune and inflammatory cells, airway smooth muscle, and pulmonary nerves. Isoenzyme phosphodiesterase 4 inhibitors are novel therapeutic agents in late clinical development for the treatment of chronic obst ructive pulmonary disease and asthma, both diseases with significant unmet treatment needs. This activity is intended for physicians. Apart from smoking cessation, there are no other treatments that slow lung function decline. "We do not yet know whether the effects over a longer period of time may translate into attenuation of the accelerated rate of decline of lung function that characterizes patients with COPD and leads to .

A comment will be made whether lung cancer is induced to patients receiving phosphodiesterase (PDE)-4 inhibitors from the drug or former smoking habit. This can make them too narrow for enough air to pass in and out of the lungs. Its clinical effects have been extensively reviewed elsewhere. Phosphodiesterase 4 Inhibition in the Treatment of Psoriasis, Psoriatic Arthritis and Other Chronic Inflammatory Diseases. Do not use this medicine to treat sudden breathing problems. Selective inhibitors of this enzyme have been available for a number of years and show a broad spectrum of activity in animal models of COPD and asthma. Chronic obstructive pulmonary disease (COPD) is estimated to affect 32 million persons in the United States and is the fourth leading cause of death in this country. Phosphodiesterase inhibitors (PDE inhibitors) are a class of agents acting on phosphodiesterase enzymes. Therefore, selective PDE4 inhibitors may also provide a therapeutic option for very pre-term infants with bronchopulmonary dysplasia (BPD). , of the compound UK-500,001 .
