Xanthine DerivativesXanthine derivatives such as theophylline inhibit phosphodiesterase, resulting in an increase in cAMP. Theophylline, also known as 1,3-dimethylxanthine, is a phosphodiesterase inhibiting drug used in therapy for respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma under a variety of brand names. resulting from hydroxylation of Xanthine derivatives (uric acid derivatives) or demethylation products showed to be able to repair radicals resulting from adenine oxidation [12]. Pregnancy Category C Therapeutic actions. Chemical Formula. Classifications of bronchodilators include beta 2-agonists, anticholinergics, and xanthine derivatives. 48:12.12 Xanthine Derivatives* 48:16 Expectorants 48:24 Mucolytic Agents* 48:36 Pulmonary Surfactants 48:48 Vasodilating Agents* 48:92 Respiratory Agents, Miscellaneous 52:00 Eye, Ear, Nose, and Throat (EENT) Preparations 52:02 Antiallergic Agents 52:04 Anti-infectives 52:04.04 Antibacterials 52:04.16 … Xanthine CAS registry number (Chemical Abstracts Service) 0000069-89-6. 5.14 Xanthine Derivatives Open Resources for Nursing (Open RN) Theophylline is a xanthine derivative. Two xanthine derivatives with high affinity and high selectivity for adenosine A 1 receptor, 8-cyclopentyl-1,3-dipropylxanthine (DPCPX) (Lohse et al., 1987) and its analog 8-dicyclopropylmethyl-1,3-dipropylxanthine (KF15372) (Shimada et al., 1991), were selected as lead compounds for in vivo imaging. Clinical significance. In contrast to other, more potent stimulants like sympathomimetic amines, xanthines … Classification: Bronchodilator, Xanthine. Anticholingeric Agent. Therapeutic Categories. Decrease inflammation. Derivatives of xanthine (known collectively as xanthines) are a group of alkaloids commonly used for their effects as mild stimulants and as bronchodilators, notably in the treatment of asthma or influenza symptoms. Mast Cell Stabilizers. ... Ipratropium Bromide classification. Theophylline competitively blocks phosphodiesterase which increases cAMP tissue concentrations causing bronchodilatation, diuresis, CNS and cardiac stimulation, and gastric acid secretion. Mechanism of Action. Xanthine derivative Molecular Weight. These medications open the airways, but they work on different receptors in the body. A methyl xanthine derivative from tea with diuretic, smooth muscle relaxant, bronchial dilation, cardiac and central nervous system stimulant activities. The increase in cAMP causes relaxation of bronchial smooth muscle. Indications Inhalation and Intranasal spray. Theophylline relaxes bronchial smooth muscle by inhibition of the enzyme phosphodiesterase and suppresses airway responsiveness to stimuli that cause bronchoconstriction. The xanthine derivatives are agents that resemble natural occurring xanthines such as caffeine, theobromine and methylxanthines. 152. Xanthine derivatives Accession Number DBCAT001034 (DBCAT000503, DBCAT001028, DBCAT001220, DBCAT002203, DBCAT002692, DBCAT003295) Description. Ipratropium Bromide administration. C5-H4-N4-O2.
