Efficacy and safety of combined diclofenac 0.1 % and gentamicin 0.3 eyedrops after phacoemulsification
1997
To study the efficacy of combined diclofenac 0.1% and gentamicin 0.3% (Digen) eyedrops to treat postoperative inflammation and prevent ocular infection in eyes having phacoemulsification.Department of Ophthalmology, University of Milan, San Paolo Hospital, Milan; Eye Clinic, University of Verona; and Department of Ophthalmology, University of Palermo, Italy.This double-masked, randomized, clinical trial comprised 90 patients; 45 received Digen and 45, gentamicin 0.3% eyedrops. The main outcome measure of the study was the reduction in signs and symptoms of inflammation, graded on a four-point scale. Also assessed were the presence of bacteria in the conjunctival swab and the proportion of p…
Evaluation of the clinical and histological effectiveness of isoretinoin in the therapy of oral leukoplakia. Ten years of experience: is management s…
2006
Various studies have evaluated the therapeutic effectiveness of vitamin A derivatives in the treatment of oral leukoplakia (OL). Not all the studies have shown concordant results. The aim of our study, which has a 10-year follow-up, was to test the effectiveness of topical therapy based on 0.18% isotretinoin by comparing it with that most frequently used, i.e., at 0.05% concentration. Forty patients with an established diagnosis of OL were involved in the study. The patients were randomly divided into two groups and the drug was administered topically at 0.05% and 0.18% concentrations. The drug was applied twice a day for 3 consecutive months; then it was suspended for 1 month, and the biop…
Allopurinol has Immunomodulating Activity following Topical and Systemic Application in Experimental Autoimmune Uveitis
2001
PurposeAllopurinol has beneficial effects in the systemic treatment of lens-induced uveitis and experimental autoimmune uveitis (EAU). This is believed to be due to a reduction of oxidative tissue damage through its dose-dependent free radical scavenging ability, and to an immunomodulating effect. The purpose of this study was to demonstrate the immunological effects on the IgG-antibody repertoire in EAU after topical and systemic allopurinol and steroids.MethodsWe assigned 43 male Lewis rats to 6 different groups: healthy rats (BASE, n=3), EAU without therapy (CTRL, n=9); systemic treatment with allopurinol (ALSYS, n=9, 50 mg/kg body wt.i.v., given every three days for two weeks), topical …
Studies on the Intravesical Action of Topically Administered G 3 H-Doxorubicin Hydrochloride in Men: Plasma Uptake and Tumor Penetration
1980
AbstractDoxorubicin hydrochloride has been used for the treatment and prevention of recurrences of transitional cell carcinoma. Ideal indications for the drug and side effects have not been determined. In this regard the penetration of the drug into the bladder wall and the urothelium as a urinary blood barrier is of interest. Using a tritium label we have investigated tumor penetration and transmucosal plasma uptake of doxorubicin hydrochloride after intravesical application in 7 patients with stage A bladder tumors. Of the 7 patients 5 were free of tumor following transurethral resection and 2 had recurrent disease. The patients free of tumor received 40mg. doxorubicin hydrochloride per 3…
Efficacy and tolerability of preservative-free eye drops containing a fixed combination of dorzolamide and timolol in glaucoma patients.
2010
To evaluate the efficacy and tolerability of preservative-free eye drops (dorzolamide/timolol) in routine management of preservative-sensitive glaucoma patients.Data from 2,298 glaucoma patients requiring intraocular pressure (IOP) reduction and suffering from intolerance to benzalkonium chloride or active agents of previously used eye drops were valid for baseline and safety analysis in this prospective, open, noncomparative, multicenter, noninterventional study. Patients were treated with preservative-free dorzolamide/timolol eye drops for 12 weeks. Main efficacy endpoint was IOP reduction after 12 weeks of treatment. Two thousand forty-nine patients were considered for efficacy analysis.…
Switching from a preserved to a preservative-free prostaglandin preparation in topical glaucoma medication.
2010
. Purpose: The purpose of this study was to investigate the tolerability and intraocular pressure (IOP) reducing effect of the first preservative-free prostaglandin tafluprost (Taflotan®) in patients exhibiting ocular surface side-effects during latanoprost (Xalatan®) treatment. Methods: A total of 158 patients were enrolled in this open-label multicentre study. Eligible patients had to have at least two ocular symptoms, or one sign and one symptom, during treatment with latanoprost. At baseline, the patients were directly switched from latanoprost to preservative-free tafluprost for 12 weeks. The patients were queried for ocular symptoms, and ocular signs were assessed by using tear brea…
Effect of the local administration of betamethasone on pain, swelling and trismus after impacted lower third molar extraction. A randomized, triple b…
2013
Objectives: The aim of this study is to compare the analgesic and anti-inflammatory effects of the local postoperative administration of a single 12-mg dose of betamethasone after the surgical removal of impacted lower third molars. Study Design: A split-mouth, triple-blind, randomized, placebo-controlled clinical trial of 25 patients requiring the surgical removal of symmetrical lower third molars was performed. In the experimental side, a 12-mg dose of betamethasone was administered submucosally after the surgical procedure, while in the control side a placebo (sterile saline solution) was injected in the same area. To assess postoperative pain, visual analogue scales and the consumption …
Effects of localmelatonin application on post-extraction sockets after third molar surgery: a pilot study
2014
Objectives: The purpose of this study was to assess the anti-inflammatory, analgesic and osteogenic early effects of melatonin on post-extraction sockets ofpatients requiring third molars extraction. Study Design: A randomized, triple-blind clinical trial was made using a split-mouth design. Both lower third molars of 10 patients were extracted and 3 mg of local melatonin or placebo were applied. Concentrations of interleukin-6 and nitrotyrosine were determined on samples of the clot from the socket by independent ELISA tests. Radiographic bone density was evaluated by measuring Hounsfield Units in panoramic and cross sections obtained by digital scanner. Statistycal analysis by Kolmogorov-…
Preemptive analgesic effectiveness of oral ketorolac plus local tramadol after impacted mandibular third molar surgery
2010
Objective: The aim of this study was to compare preemptive analgesia of oral ketorolac plus submucous local placebo with oral ketorolac plus submucous local tramadol after impacted mandibular third molar surgery. Study design: A double-blind, randomized, placebo-controlled clinical trial was conducted. Patients were randomized into two treatment groups (n = 15 per group): group A, oral ketorolac 10 mg, 30 minutes before surgery plus submucous local placebo (1 mL saline solution); group B, oral ketorolac 10 mg, 30 minutes before surgery plus submucous local tramadol (50 mg diluted in 1 mL saline solution). We evaluated the intensity of pain, time for the first analgesic rescue medication, an…
Polyhydroxyethylaspartamide-based micelles for ocular drug delivery
2009
In this paper three copolymers of polyhydroxyethylaspartamide (PHEA), bearing in the side chains polyethylene glycol (PEG) and/or hexadecylamine (C(16)) (PHEA-PEG, PHEA-PEG-C(16) and PHEA-C(16) respectively) have been studied as potential colloidal drug carriers for ocular drug delivery. The physical characterization of all three PHEA derivatives, using the Langmuir trough (LT) and micellar affinity capillary electrophoresis (MACE) techniques allowed to assume that whereas alone PHEA backbone is an inert polymer with respect to the interactions with lipid membranes and drug complexation, when PHEA chains are grafted with long alkyl chains like C(16) or in combination C(16) chains and hydrop…
