Published Studies Related to Tropicamide (Tropicamide Ophthalmic)
A double-blind, placebo-controlled, randomized, crossover pilot study of the
safety and efficacy of multiple doses of intra-oral tropicamide films for the
short-term relief of sialorrhea symptoms in Parkinson's disease patients. 
OBJECTIVE: This proof-of-concept, pilot study aimed to explore the safety and
anti-sialorrhea efficacy of single doses of intra-oral slow dissolving thin films
containing tropicamide (NH004) or placebo. METHODS: Nineteen non-demented, idiopathic stable or fluctuating PD patients who
complained of sialorrhea received 3 doses (0.3, 1, 3mg) of tropicamide and
placebo in random order, separated by 7 days...
Effective pupil dilatation with a mixture of 0.75% tropicamide and 2.5% phenylephrine: A randomized controlled trial. [2009.09]
CONCLUSIONS: The mixture of 0.75% tropicamide and 2.5% phenylephrine is superior to our standard application of 1% tropicamide alternating with 10% phenylephrine. It provides faster and more successful pupil dilatation within 40 min.
Mydriatic and cardiovascular effects of phenylephrine 2.5% versus phenylephrine 10%, both associated with tropicamide 1%. 
BACKGROUND/AIMS: To evaluate and compare cardiovascular effects (blood pressure and heart rate) of phenylephrine 2.5% versus phenylephrine 10%, and compare pupil diameter before and after instillation of eyedrops... CONCLUSION: Our results corroborate the finding that one single drop of either 2.5 or 10% phenylephrine is safe and, when 1% tropicamide is combined, satisfactory pupil dilation is achieved.

Single dose of 1% tropicamide and 10% phenylephrine for pupil dilation. [2006.11]
CONCLUSION: The 95% confidence interval of the difference in pupil size lay entirely within the range of equivalence. The single dose of 1% tropicamide and 10% phenylephrine was clinically equivalent to the three doses of the same drugs.
The mydriatic effect of multiple doses of tropicamide. [2005.11]
PURPOSE: We investigated whether two drops of 0.5% tropicamide produced a wider pupillary dilation when compared with a single drop and saline control in subjects with dark-colored irides... CONCLUSION: In young healthy subjects, compared with a single drop of tropicamide, two drops were associated with a greater degree of pupillary dilation on average over the 60-minute study period. However, the magnitude of the difference was small and not clinically significant. A single drop of tropicamide produced a pupillary diameter of at least 6 mm, which should be sufficient for the conduct of a thorough dilated fundus examination.
Clinical Trials Related to Tropicamide (Tropicamide Ophthalmic)
Single Dose of 1% Tropicamide and 10% Phenylephrine for Pupillary Dilation [Completed]
The purpose of this study is to compare the efficacy on pupillary dilation between the single
dose versus the three doses of 1% tropicamide with 10% phenylephrine for complete ocular
Intracameral Mydriasis Versus Topical Mydriasis in Cataract Surgery [Recruiting]
The purpose is to determine if an intracameral solution of 0. 2% tropicamide and 2%
phenylephrine can dilate the pupil for cataract surgery as well as pre-operative topical 1%
tropicamide and 5% phenylephrine. We will be looking at two separate groups of patients,
those with and those without pseudoexfoliation syndrome.
We will be looking at how each method affects the size of the pupil at the beginning and at
the end of cataract surgery. In addittion, we will look at what effect the two different
methods have on blood pressure and heart rate in the pre-operative, peri-operative and
Study of Myopia Prevention in Children With Low Concentration of Atropine [Recruiting]
The purpose of this study is to test the hypothesis that myopia can be prevented by using a
low concentration of atropine eyedrops once a week.
Safety and Efficacy Study of NH004 Films for Relief of Sialorrhea Symptoms in Parkinson's Disease Patients [Recruiting]
The Pathophysiology of Orthostatic Hypotension [Recruiting]
The purpose of this study is to determine the cause of low blood pressure in selective
patients who have problems with their involuntary (autonomic) nervous system. These
patients frequently have had symptoms throughout their life, and their disorder might have a
genetic basis. The biochemical, physiological and pharmacological procedures in this study
should help us define the problem and perhaps lead to more effective treatment.
