Pseudoephedrine acts directly on both alpha- and, to a lesser degree, beta-adrenergic receptors. Through direct action on alpha-adrenergic receptors in the mucosa of the respiratory tract, pseudoephedrine produces vasoconstriction. Pseudoephedrine relaxes bronchial smooth muscle by stimulating beta2-adrenergic receptors.

Pseudoephedrine is a sympathomimetic and is well-known for shrinking swollen nasal mucous membranes, so it is often used as a decongestant. It reduces tissue hyperemia, edema, and nasal congestion commonly associated with colds or allergies.

Chemical structure: This structure is also available as a 2d Mol file or as a computed 3d SD file The 3d structure may be viewed using Java or Javascript. Species with the same structure: DL-Ephedrine; Stereoisomers: Ephedrine; Benzenemethanol, α-[1-(methylamino)ethyl]-, [R-(R*,R*)]-Benzenemethanol, α-[1-(methylamino)ethyl]-

The 3D chemical structure image of PSEUDOEPHEDRINE is based on the ball-and-stick model which displays both the three-dimensional position of the atoms and the bonds between them. The radius of the spheres is therefore smaller than the rod lengths in order to provide a clearer view of the atoms and bonds throughout the chemical structure model ...

2017年2月20日 · Pseudoephedrine is an over-the-counter medication that has three sides: the good, the bad, and the ugly. It is a diastereomer of ephedrine, meaning that it has the same basic structure, but its atomic arrangement is different at one of the two stereogenic centers.

... and pseudoephedrine ( Fig. 1) are two structurally similar compounds, both of which are the main components of ephedra and isomers of each other. Both of them are adrenergic drugs. There are...

2025年1月27日 · Pseudoephedrine is a weak base (pKa, 9.4) that stimulates both α- and β-adrenergic receptors, as well as causing the release of neuronal norepinephrine. This mixed α/β adrenergic stimulation produces both hypertension and tachycardia, as opposed to the hypertension with reflex bradycardia seen with selective a agonists.

Pseudoephedrine Hydrochloride is the hydrochloride salt form of pseudoephedrine, a phenethylamine and an diastereomer of ephedrine with sympathomimetic property. Pseudoephedrine hydrochloride displaces norepinephrine from storage vesicles in presynaptic neurones, thereby releasing norepinephrine into the neuronal synapses where it stimulates ...

Pseudoephedrine (commonly abbreviated as PSE) is a decongestant. The salts pseudoephedrine hydrochloride and pseudoephedrine sulfate are found in many over-the-counter drugs either as single-ingredient preparations, or more commonly in combination with antihistamines, paracetamol (acetaminophen) and/or ibuprofen.
