PURPOSE The aim of the present study was to examine the effects of switching from Latanoprost ophthalmic solution containing a preservative to preservative-free Tafluprost ophthalmic solution or Tafluprost containing a preservative on ocular surfaces. MATERIALS AND METHODS Forty patients (40 eyes) with glaucoma (mean age: 62.0 ± 10.9 years) using Latanoprost with preservative for six months o...
CONTEXT Botulinum A exotoxin is used for various indications, including the treatment of dynamic forehead lines. OBJECTIVE To determine whether injection with botulinum A exotoxin reconstituted with preservative-containing normal saline (isotonic sodium chloride) is less painful than injection with exotoxin that has been reconstituted with preservative-free saline. DESIGN Two arms: (1) retr...
BACKGROUND The aim of this work is to evaluate efficacy and tolerability of preservative containing 0.0015% tafluprost and preservative-free 0.0015% tafluprost using a prospective crossover study. METHODS Primary open angle glaucoma (POAG) and normotensive glaucoma (NTG) patients were randomized enrolled. Group 1 ("NPT to PT") patients used preservative-free 0.0015% tafluprost (NPT) for 6 mon...
A universal diluting fluid (UDF) was developed for use in membrane filtration sterility testing. Diuting fluid is used to free the filter membrane of preservative residues which could inhibit microbial recovery. Current procedures employ one of several fluids described by the United States Pharmacopeia. UF was designed to utilize the neutralizing capabilities of a combination of inactivating ag...
INTRODUCTION Glaucoma patients frequently exhibit ocular surface side effects during treatment with prostaglandin eye drops. The present work investigated whether glaucoma patients suffering from signs and symptoms of ocular surface disease while using preserved latanoprost eye drops benefited from switching to preservative-free tafluprost eye drops. PATIENTS AND METHODS The analysis was base...
The quality of biological samples greatly affects the accuracy of scientific results. However, RNA in cryopreserved tissues gradually degrades during storage, leading to errors in the results of subsequent experiments. A suitable sample preservative solution can prolong storage and enhance the research value of samples. Here, we developed a sample preservative solution using the properties of t...
Patient satisfaction with glaucoma treatment has been poorly studied to date. Because glaucoma is a chronic condition in which the therapeutic response is dependent on adherence to treatment, patient acceptability is an important factor in achieving satisfactory outcomes. This multicenter, international (Belgium, the Netherlands, and Spain), epidemiological convenience sample survey among patie...
Timolol maleate has a molecular weight of 432.50. It is a white, odorless, crystalline powder which is soluble in water, methanol, and alcohol. Timolol maleate is stable at room temperature. Timolol maleate ophthalmic solution is supplied in two formulations: Ophthalmic Solution TIMOPTIC* (timolol maleate ophthalmic solution), which contains the preservative benzalkonium chloride; and Ophthalmi...
Antimicrobial preservatives are excipients added to multi-dose containers of both sterile and non-sterile drug products. Antimicrobial preservatives are used primarily to inhibit growth of microbial contamination occurring during the period of use. Demonstration of antimicrobial preservative effectiveness is required for these functional excipients. This article reviews key factors for consider...
