• Ipratropium bromide is an anticholinergic (parasympatholytic) agent which, based on animal studies, appears to inhibit vagally mediated reflexes by antagonizing the action of acetylcholine, the transmitter agent released from the vagus nerve. (theodora.com)
  • Combivent® (ipratropium bromide and albuterol sulfate) Inhalation Aerosol is expected to maximize the response to treatment in patients with chronic obstructive pulmonary disease (COPD) by reducing bronchospasm through two distinctly different mechanisms, anticholinergic (parasympatholytic) and sympathomimetic.

  • Tropicamide is a parasympatholytic agent which, when applied topically to the eye, blocks the responses of the sphincter muscle of the iris and the ciliary muscle to cholinergic stimulation, producing dilation of the pupil and paralysis of the ciliary muscle. (nih.gov)
