Metaproterenol is a synthetic β2-adrenergic receptor agonist used as a bronchodilator for the treatment of asthma and other respiratory conditions. It was synthesized in the 1960s and works by stimulating the β2 receptors in the smooth muscle of the airways, leading to relaxation and dilation of the bronchioles. This effect relieves bronchospasm, making breathing easier. Its selectivity for β2 receptors contributes to its efficacy in treating asthma, as it has fewer cardiovascular side effects compared to non-selective β-agonists. Metaproterenol is typically administered via inhalation, though oral and parenteral routes are also available. Its importance lies in its ability to provide rapid relief of asthma symptoms. Research on metaproterenol focuses on its efficacy and safety in different patient populations, its potential for long-term use, and its role in combination therapy with other asthma medications.'

| Encephalitis, Polio [description not available] | 0 | 2.06 | 1 | 0 |
| Poliomyelitis An acute infectious disease of humans, particularly children, caused by any of three serotypes of human poliovirus (POLIOVIRUS). Usually the infection is limited to the gastrointestinal tract and nasopharynx, and is often asymptomatic. The central nervous system, primarily the spinal cord, may be affected, leading to rapidly progressive paralysis, coarse FASCICULATION and hyporeflexia. Motor neurons are primarily affected. Encephalitis may also occur. The virus replicates in the nervous system, and may cause significant neuronal loss, most notably in the spinal cord. A rare related condition, nonpoliovirus poliomyelitis, may result from infections with nonpoliovirus enteroviruses. (From Adams et al., Principles of Neurology, 6th ed, pp764-5) | 0 | 2.06 | 1 | 0 |
