Chemically, ipratropium bromide is a quaternary ammonium compound (which is indicated by the -ium per the BAN and the USAN) [25] obtained by treating atropine with isopropyl bromide, thus the name: isopropyl + atropine. [citation needed] It is chemically related to components of the plant Datura stramonium, which was used in ancient India for ...
Important [5] muscarinic antagonists include atropine, hyoscyamine, hyoscine butylbromide and hydrobromide, ipratropium, tropicamide, cyclopentolate, pirenzepine and scopalamine. Muscarinic antagonists such as ipratropium bromide can also be effective in treating asthma , since acetylcholine is known to cause smooth muscle contraction ...
Plants can protect themselves from abiotic stress in many different ways, and most include a physical change in the plant’s morphology. Phenotypic plasticity is a plant’s ability to alter and adapt its morphology in response to the external environments to protect themselves against stress. [ 2 ]
Lightning strikes kill or injure plants, from root crops like beet and potato, which are instantly cooked in the ground, to trees such as coconut, through effects such as sudden heat and pressure shock waves created when water inside the plant flashes to steam. This can rupture stems and scorch any plant parts. [8] Ozone, a gas, causes injury ...
An anti-asthmatic agent, also known as an anti-asthma drug, refers to a drug that can aid in airway smooth muscle dilation to allow normal breathing during an asthma attack or reduce inflammation on the airway to decrease airway resistance for asthmatic patients, or both. The goal of asthmatic agents is to reduce asthma exacerbation frequencies ...
Plants are able to determine what types of herbivore species are present, and will react differently given the herbivore's traits. If certain defense mechanisms are not effective, plants may turn to attracting natural enemies of herbivore populations. For example, wild tobacco plants use nicotine, a neurotoxin, to defend against herbivores ...
Plants utilize many mechanisms to recover fitness from damage. Such traits include increased photosynthetic activity, compensatory growth, phenological changes, utilizing stored reserves, reallocating resources, increase in nutrients uptake, and plant architecture (Rosenthal and Kotanen 1994; Strauss and Agrawal 1999; Tiffin 2000).
Ipratropium bromide/salbutamol, sold under the brand name Combivent among others, is a combination medication used to treat chronic obstructive pulmonary disease (COPD). [ 1 ] [ 4 ] [ 5 ] It contains ipratropium (an anticholinergic ) and salbutamol (albuterol, a β 2 -adrenergic agonist ).
