Tarodyn
Tarodyn - General Information
A muscarinic antagonist used as an antispasmodic, in some disorders of the gastrointestinal tract, and to reduce salivation with some anesthetics. [PubChem]
Pharmacology of Tarodyn
Tarodyn decreases acid secretion in the stomach. Hence it can be used for treating ulcers in the stomach and small intestine, in combination with other medications. In anesthesia, glycopyrrolate injection serves as a preoperative antimuscarinic operation that reduces salivary, tracheobronchial, and pharyngeal secretions, as well as decreases the acidity of gastric secretions blocks cardiac vagal inhibitory reflexes during intubation
Tarodyn for patients
Because Robinul Injection may produce drowsiness or blurred vision, the patient should be cautioned not to engage in activities requiring mental alertness and/or visual acuity such as operating a motor vehicle or other machinery, or performing hazardous work while taking this drug.
The patient also should be cautioned about the use of this drug during exercise or hot weather since overheating may result in heat stroke.
The patient may experience a possible sensitivity of the eyes to light.
Tarodyn Interactions
The concurrent use of Robinul Injection with other anticholinergics or medications with anticholinergic activity, such as phenothiazines, antiparkinson drugs, or tricyclic antidepressants, may intensify the antimuscarinic effects and may result in an increase in anticholinergic side effects.
Concomitant administration of Robinul Injection and potassium chloride in a wax matrix may increase the severity of potassium chloride-induced gastrointestinal lesions as a result of a slower gastrointestinal transit time.
Tarodyn Contraindications
Known hypersensitivity to glycopyrrolate or any of its inactive ingredients.
In addition, in the management of peptic ulcer patients, because of the longer duration of therapy, Robinul Injection may be contraindicated in patients with the following concurrent conditions: glaucoma; obstructive uropathy (for example, bladder neck obstruction due to prostatic hypertrophy); obstructive disease of the gastrointestinal tract (as in achalasia, pyloroduodenal stenosis, etc.); paralytic ileus, intestinal atony of the elderly or debilitated patient; unstable cardiovascular status in acute hemorrhage; severe ulcerative colitis; toxic megacolon complicating ulcerative colitis; myasthenia gravis.
Additional information about Tarodyn
Tarodyn Indication: For use as a preoperative antimuscarinic to reduce salivary, tracheobronchial, and pharyngeal secretions, to reduce the volume and free acidity of gastric secretions and to block cardiac vagal inhibitory reflexes during induction of anesthesia and intubation.
Mechanism Of Action: Tarodyn binds to the muscarinic acetylcholine receptor. Like other anticholinergic (antimuscarinic) agents, inhibits the action of acetylcholine on structures innervated by postganglionic cholinergic nerves and on smooth muscles that respond to acetylcholine but lack cholinergic innervation. These peripheral cholinergic receptors are present in the autonomic effector cells of smooth muscle, cardiac muscle, the sinoatrial node, the atrioventricular node, exocrine glands and, to a limited degree, in the autonomic ganglia. Thus, it diminishes the volume and free acidity of gastric secretions and controls excessive pharyngeal, tracheal, and bronchial secretions.
