Chemical Formula. Mast Cell Stabilizers. Xanthine derivative Xanthine DerivativesXanthine derivatives such as theophylline inhibit phosphodiesterase, resulting in an increase in cAMP. This job aid also provides an overview of the approved security classification documents that assist in analyzing and evaluating … Classifications of bronchodilators include beta 2-agonists, anticholinergics, and xanthine derivatives. Xanthine CAS registry number (Chemical Abstracts Service) 0000069-89-6. Xanthine Derivatives. These medications open the airways, but they work on different receptors in the body. C5-H4-N4-O2. Mechanism of Action. The major pharmacologic actions of the xanthines are inhibition of tissue phosphodiesterases which i … These are plant alkaloids and components of coffee, tea and chocolate. A methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac and central nervous system stimulant activities. 5.14 Xanthine Derivatives Open Resources for Nursing (Open RN) Theophylline is a xanthine derivative. Classification: Bronchodilator, Xanthine. Indications As a member of the xanthine family, it bears structural and pharmacological similarity to theobromine … The increase in cAMP causes relaxation of bronchial smooth muscle. The xanthine derivatives are agents that resemble natural occurring xanthines such as caffeine, theobromine and methylxanthines. Therapeutic Categories. 152. Theophylline competitively blocks phosphodiesterase which increases cAMP tissue concentrations causing bronchodilatation, diuresis, CNS and cardiac stimulation, and gastric acid secretion. Inhalation and Intranasal spray. ... Ipratropium Bromide classification.
