Published Studies Related to Betoptic S (Betaxolol Ophthalmic)
Efficacy of brinzolamide and levobetaxolol in pediatric glaucomas: a randomized clinical trial. [2008.06]
PURPOSE: To describe the safety and clinical response on elevated intraocular pressure (IOP) of brinzolamide and levobetaxolol in pediatric patients under 6 years of age... CONCLUSIONS: Both brinzolamide and levobetaxolol were well tolerated. Both drugs provided clinically relevant IOP reductions for patients not on a previous medication, although efficacy is, in part, contingent upon diagnosis.
Penetration of betaxolol HCL ionic suspension 0.25% and betaxolol HCL solution 0.50% into the aqueous humor. [2007.05]
PURPOSE: To determine the intraocular penetration of topical drops of betaxolol HCl 0.25% suspension and betaxolol HCl 0.50% solution into the aqueous humor... CONCLUSIONS: The mean aqueous humor concentration of betaxolol 0.25% suspension was higher than betaxolol 0.50% solution; however, the difference was not statistically significant. With twofold reduced concentration and similar anterior chamber penetration, betaxolol 0.25% suspension could be first choice for Beta 1 selective blocker therapy when considered for patients with glaucoma.
Compliance, clinical outcome, and quality of life of patients with stable angina pectoris receiving once-daily betaxolol versus twice daily metoprolol: a randomized controlled trial. 
BACKGROUND: A randomized, controlled trial was conducted in an outpatient setting to examine the effect of beta-blocker dosing frequency on patient compliance, clinical outcome, and health-related quality of life in patients with stable angina pectoris... CONCLUSIONS: The study demonstrates that patient compliance with once-daily betaxolol is significantly better than with twice daily metoprolol. Similarly, this treatment provides better quality of life. These results demonstrate possible therapeutic advantages of once-daily over twice-daily beta-blockers in the treatment of stable angina pectoris.
Betaxolol is equivalent to carvedilol in patients with heart failure NYHA II or III: result of a randomized multicenter trial (BETACAR Trial). [2006.11.10]
BACKGROUND: In a recent COMET trial (Lancet 362, 2003:7-13) it could be demonstrated that carvedilol < or = 50 mg/d was superior to metoprolol tartrate < or = 100 mg/d in the treatment of heart failure patients NYHA II-IV. OBJECTIVES: It was investigated whether the superiority of carvedilol with its beta1, beta2 and alpha-blocking potency will persist in a comparison to a highly selective beta1-blocker with a long plasma half-time such as betaxolol... CONCLUSIONS: The long acting highly selective beta1-blocker betaxolol in an adequate dosage is not inferior to carvedilol in terms of exercise tolerance, safety and effects on left ventricular function.
Betaxolol hydrochloride ophthalmic suspension 0.25% and timolol gel-forming solution 0.25% and 0.5% in pediatric glaucoma: a randomized clinical trial. [2009.08]
PURPOSE: To describe the safety profile and clinical response on elevated intraocular pressure (IOP) of betaxolol hydrochloride ophthalmic suspension 0.25% (betaxolol) and timolol maleate ophthalmic gel-forming solution (TGFS) (0.25% and 0.5%), in subjects under 6 years of age... CONCLUSIONS: Betaxolol ophthalmic suspension 0.25%, TGFS 0.25%, and TGFS 0.5% were well tolerated. Despite low responder rates, all 3 treatments produced statistically significant mean reductions in IOP in pediatric glaucoma subjects.
Clinical Trials Related to Betoptic S (Betaxolol Ophthalmic)
Safety and Efficacy Study of BETOPTIC S 0.25% and Timolol Gel-Forming Solution 0.25% and 0.5% in Pediatric Patients With Glaucoma or Ocular Hypertension. [Completed]
To evaluate the safety and efficacy of BETOPTIC S and Timolol Gel-forming solution in
pediatric patients. Patients will dose with study drug at 8 am and 8 pm daily for twelve
weeks. Patients will have vision tested, slit lamp exam, blood pressure and pulse checks at
each visit. Patients will have a dilated fundus exam and corneal measurements taken at first
and last visit.
Early Manifest Glaucoma Trial (EMGT) [Active, not recruiting]
The primary purpose is to compare the effect of immediate therapy to lower the intraocular
pressure (IOP) versus late or no treatment on the progression of newly detected open-angle
glaucoma, as measured by increasing visual field loss and/or optic disc changes.
The secondary purposes are to determine the extent of IOP reduction attained by treatment, to
explore factors that may influence glaucoma progression, and to describe the natural history
of newly detected glaucoma.
Renin-Guided Therapeutics in the Management of Untreated, Uncontrolled, or Complicated Hypertension [Completed]
Plasma renin values determine whether volume or vasoconstrictor (renin) factors predominate
in elevating blood pressure and are useful in selecting effective antihypertensive
The researchers hypothesize that:
1. Plasma renin-guided therapeutics will improve systolic and diastolic blood pressure
control in patients with untreated hypertension as well as in patients with treatment
refractory or resistant hypertension that are managed by Clinical Hypertension
2. Renin-guided therapeutics will reduce the number of medications required to maintain
blood pressure control to <140/90 mmHg in hypertensive patients receiving 3 or more
medications, while under the care of a Clinical Hypertension Specialist.
3. Renin-guided therapeutics selection will reduce the total cost of antihypertensive care
provided by Clinical Hypertension Specialists.
