Hyoscyamine (Hyoscyamine Sulfate) - Summary



Hyoscyamine Sulfate SL Tablets 0.125 mg are formulated for sublingual and oral administration. Hyoscyamine Sulfate SL
Tablets 0.125 mg disintegrate within seconds after placement under or on the tongue, allowing it to be swallowed with or
Hyoscyamine Sulfate is one of the principal anticholinergic/antispasmodic components of belladonna alkaloids.

Hyoscyamine Sulfate is effective as adjunctive therapy in the treatment of peptic ulcers. It can also be used to control gastric secretion, visceral spasm and hypermotility in spastic colitis, spastic bladder, cystitis, pylorospasm, and associated abdominal cramps. May be used in functional intestinal disorders to reduce symptoms such as those seen in mild dysenteries, diverticulitis, and
acute enterocolitis. For use as adjunctive therapy in the treatment of irritable bowel syndrome (irritable colon, spastic colon, mucous colitis) and functional gastrointestinal disorders. Also used as adjunctive therapy in the treatment of neurogenic bladder and neurogenic bowel disturbances (including the splenic flexure syndrome and neurogenic colon). Hyoscyamine Sulfate is indicated
along with morphine or other narcotics in symptomatic relief of biliary and renal colic; as a "drying agent" in the relief of symptoms of acute rhinitis; in the therapy of parkinsonism to reduce rigidity and tremors and to control associated sialorrhea and hyperhidrosis. May be used in the therapy of poisoning by anticholinesterase agents.

Published Studies Related to Hyoscyamine

Sublingual hyoscyamine spray as premedication for colonoscopy: a randomized double-blinded placebo-controlled trial. [2008.07]
BACKGROUND: Colonic motility and spasm during colonoscopy may affect duration and quality of the examination as well as patient comfort during and after the procedure. Previous studies assessing the utility of antispasmodic agents in colonoscopy demonstrated conflicting results. The aim of this study was to determine the effect of sublingual hyoscyamine spray (IB-Stat, Inkine Pharmaceutical) on the performance of colonoscopy... CONCLUSIONS: Procedural difficulty and colonic motility scores were significantly lower in subjects who received sublingual hyoscyamine before colonoscopy.

Sublingual L-hyoscyamine for duodenal antimotility during ERCP: a prospective randomized double-blinded study. [2007.10]
BACKGROUND: ERCP is often made difficult by duodenal motility. Glucagon is typically used to inhibit this motility. L-hyoscyamine is an antimuscarinic, anticholinergic agent shown to be a feasible intravenous alternative to glucagon. OBJECTIVE: Demonstrate whether pre-ERCP sublingual L-hyoscyamine reduces the amount of glucagon required to complete ERCP... CONCLUSIONS: Preprocedure administration of sublingual L-hyoscyamine did not reduce the amount of glucagon required to complete ERCP.

Clinical Trials Related to Hyoscyamine

Efficacy of Open Label Placebo in Children With FGIDs [Recruiting]
This study is aimed at investigating the efficacy of placebo for symptom relief in children with abdominal pain related functional gastrointestinal disorders.

RSA Study Using Two Types of Uncemented Acetabular Components and the Uncemented HA Coated Symax Stem [Recruiting]
The Trident Tritanium acetabular component of a total hip prosthesis is a new developed uncemented acetabular component. In this randomized controlled trial (RCT) the tritanium cup will be compared with the Trident HA acetabular component in two equal sized groups. The Symax HA coated stem will be used as femoral component in both groups. Study Objectives:

- The primary objective is to determine the prosthetic migration of the uncemented

acetabular and femoral total hip components using model based RSA technique

- Secondary objectives are on one hand to assess clinical outcome on the other hand

assessing patient satisfaction in both groups using Harris Hip Score, Oxford Hip Score, WOMAC, and EQ-5D questionnaires

- Tertiary objective is to assess bone remodeling of the uncemented acetabular components

and the HA-coated Symax hip stem using QCT derived from usinf F18-fluoride PET in a cohort of 12 consecutive patients of this RCT A total of 50 patients will be enrolled in this RCT divided into two equal groups. Patients have to fulfill the inclusion and exclusion criteria. All evaluations will be done pre-operatively with 2 weeks before surgery, and after surgery at 4 weeks, 3 and 6 months and 1 and 2 years.

RCT Comparing the DEXA Results of the HA-Omnifit Versus the Symax Uncemented Hip Stem [Completed]
Thr purpose of this study is to compare the clinical and radiological results, as well as the femur bone density measurements of two uncemented total hip prostheses during 5 years of follow up.

A Comparative Study of In-vivo Wear Between 28 mm and 40 mm Metal Heads [Active, not recruiting]
Prospective, singlecentre, randomized clinical study; series of patients with a 5-years patient evaluation period.
