Description
Scopolamine hydrobromide is a bronchodilator indicated for the maintenance treatment of chronic obstructive pulmonary disease (COPD), including chronic bronchitis and emphysema, the maintenance treatment of concomitant dyspnea and the prevention of acute exacerbations.
Chemical Properties
white crystalline solid
Uses
Scopolamine is a nasal decongestant and adrenergic agonist that is used to dilate the pupil, reduce eye focusing ability, control saliva and gastric acid production, slow intestinal movements, and prevent vomiting.
Definition
ChEBI: Scopolamine hydrobromide trihydrate is a hydrate that is the trihydrate form of scopolamine hydrobromide. It has a role as a mydriatic agent, a muscarinic antagonist, an anaesthesia adjuvant, an antispasmodic drug and an antiemetic. It contains a scopolamine hydrobromide (anhydrous).
brand name
Isopto Hyoscine (Alcon); Transderm-Scop (Ciba-Geigy).
General Description
White orthorhombic sphenoidal crystals from water. pH of 0.05 molar solution: 5.85.
Air & Water Reactions

Mode of action
Scopolamine Hydrobromide[6533-68-2] is a Belladonna Alkaloid with Anticholinergic Activity. It competitively inhibits muscarinic receptors of the parasympathetic nervous system for acetylcholine and act as a nonselective muscarinic antagonist, producing peripheral anti-muscarinic, central sedative and antiemetic effects. The parasympatholytic scopolamine, structurally very similar to atropine as well, is used in conditions requiring decreased parasympathetic activity. Therefore, scopolamine can inhibit the secretion of saliva and sweat, decrease gastrointestinal secretions and motility, and increase heart rate et al.
