Lokren (Betaxolol) is a beta-adrenergic blocking agent. The nerves of the sympathetic nervous system--a subdivision of the nervous system--release a chemical related to adrenaline which binds to the heart-rate controlling cells in the heart as well as the muscles of the heart. Binding causes the heart to beat faster and the muscles of the heart to contract more vigorously and work harder.
