A retrospective analysis of intraocular pressure changes after cataract surgery with the use of prednisolone acetate 1% versus difluprednate 0.05%.[Pubmed:27920493]
Clin Ophthalmol. 2016 Nov 23;10:2329-2336.
PURPOSE: To compare the effect of topical Prednisolone Acetate 1% (PA) used after routine cataract surgery to the effect of difluprednate 0.05% (DFBA) used for the same indication on intraocular pressure (IOP). METHODS: An electronic query was created to gather information from all cataract surgeries between January 2010 and January 2015 within the electronic health record database at Barnet Dulaney Perkins, a multicenter, multiphysician private practice in Phoenix, Arizona. Information collected included age, sex, diabetes status, glaucoma history, medication regimen (use of PA or DFBA), and IOP before surgery, 5-10 days postoperatively (TP1) and 3-6 weeks postoperatively (TP2). Postoperative IOP measurements were compared to baseline IOP measurement in each patient. RESULTS: Regardless of steroid used, all patients in this study experienced an increase in IOP within TP1 and returned to baseline IOP (+/-2.0 mmHg) by TP2. Patients who received DFBA showed a statistically significant increase in IOP at TP1 compared to those on PA (P<0.001) with the mean IOP an average 0.60 mmHg higher (95% CI =0.3, 0.9). The odds ratio of a clinically significantly increased IOP at TP1 (defined as overall IOP >/=21 mmHg and an increase of >/=10 mmHg) in DFBA-treated patients was 1.84 (95% CI =1.4, 2.6). In patients treated with PA, 3% reached a significantly increased IOP, compared to 4.4% of patients in the DFBA group (P<0.05). Risk factors for increased IOP were identified, and include advanced age (>75) (P<0.005) and a history of glaucoma (P<0.001). CONCLUSION: In postoperative cataract patients, use of DFBA increased the risk of a clinically significant IOP increase.
Comparison of prednisolone acetate 1.0% and difluprednate ophthalmic emulsion 0.05% after cataract surgery: Incidence of postoperative steroid-induced ocular hypertension.[Pubmed:28366370]
J Cataract Refract Surg. 2017 Feb;43(2):223-227.
PURPOSE: To compare intraocular pressure (IOP) outcomes between 2 common, commercially available corticosteroid drops: difluprednate ophthalmic emulsion 0.05% and Prednisolone Acetate 1.0%. SETTING: TLC Eyecare and Laser Centers, Jackson, Michigan, USA. DESIGN: Retrospective chart review. METHODS: The outcomes of consecutive patients who had uneventful cataract surgery from April 2013 to September 2013 and used Prednisolone Acetate postoperatively were compared with the outcomes of consecutive patients who had uneventful cataract surgery from June 2014 to October 2014 and used difluprednate postoperatively. RESULTS: The study included 224 eyes treated with Prednisolone Acetate 4 times daily for 30 days and 225 eyes treated with difluprednate 2 times daily for 30 days. There was no significant difference between the 2 groups in age, sex, or race. In addition, the mean IOP did not differ significantly between the Prednisolone Acetate group and the difluprednate group at the preoperative measurement or 1 month after surgery, nor was there a difference in the 1-month change in IOP between groups. No association was found between the incidence of a 6 mm Hg or higher increase in IOP 1 month after surgery and steroid treatment. One month postoperatively, 4 eyes in the Prednisolone Acetate group and 5 eyes in the difluprednate group had an IOP higher than 21 mm Hg. CONCLUSIONS: There was no significant difference in the mean IOP or percentages showing IOP elevation between eyes treated with difluprednate and eyes treated with Prednisolone Acetate after cataract surgery. This was likely the result of low-frequency dosing and short duration of steroid use.
To Study the Efficacy of Difluprednate Ophthalmic Emulsion and Prednisolone Acetate Ophthalmic Suspension on Post-operative Inflammation in Cataract Surgery.[Pubmed:28208898]
J Clin Diagn Res. 2016 Dec;10(12):NC05-NC08.
INTRODUCTION: Senile cataract is the most common cause of visual impairment. Removal of cataract and implantation of intraocular lens implantation (IOL) is the main surgical approach for cataract. The major block in quick visual rehabilitation of the patient is post-operative inflammation. To limit post-operative inflammation corticosteroids drugs are used in routine prophylactically. Topical Prednisolone Acetate 1% and betamethasone 0.1% remain gold standard to control post-operative inflammation but newer drugs like difluprednate, loteprednol are also effective in controlling inflammation. AIM: To study the efficacy of difluprednate ophthalmic emulsion and Prednisolone Acetate ophthalmic suspension on Post-operative inflammation in cataract surgery (clear corneal phacoemulsification with foldable IOL). MATERIALS AND METHODS: This study was carried out on 100 patients having visually significant cataract requiring surgery, clear corneal phacoemulsification with foldable intraocular lens implantation was done in all patients. Patients were randomly divided into two groups. In group A topical 1% Prednisolone Acetate ophthalmic suspension was administered six times a day Post-operatively. In group B 0.05% difluprednate ophthalmic emulsion was administered six times a day post-operatively. Efficacy of drug was evaluated in terms of decrease in ocular pain, anterior chamber reaction in the form of aqueous cells and flare and final visual acuity at 4 weeks. RESULTS: In this study, 92% of patients in group A and 90% of patients in group B had BCVA 6/6. None of the patients in group A had ocular pain. In group B, 96% patients had no ocular pain. Remaining 4% had mild discomfort but required no medication. 98% of patients in group A and 100% of patients in group B presented with clearance of aqueous cells at the end of study. Only 2% of patients in group A had showed cell score (+/-). CONCLUSION: Though Prednisolone Acetate has been the gold standard anti inflammatory agent, 0.05% Difluprednate ophthalmic emulsion is equally effective in treatment of post-operative inflammation. Difluprednate have added an advantage of uniform drug dosage and absence of harmful preservative.
Pharmacodynamic study of eprosartan mesylate-loaded transfersomes Carbopol((R)) gel under Dermaroller((R)) on rats with methyl prednisolone acetate-induced hypertension.[Pubmed:28237913]
Biomed Pharmacother. 2017 May;89:177-184.
The objective of present study was to prepare eprosartan mesylate (EM)-loaded transfersomes Carbopol((R)) gel and characterized for various parameters, including in vitro skin permeation, in vivo antihypertensive study, skin irritation, and histological study. Furthermore, effect of transfersomes gel on angiotensin II type-1 receptor (AT1R) mRNA and protein expressions on smooth vascular muscles of aorta was determined by real-time polymerase chain reaction (RT-PCR) and western blot analysis. The physical evaluation parameters were detected to be in correspondence with reference marketed gel formulation. The transdermal flux, permeability coefficient, and Tlag of EM from transfersomes gel were found to be 26.76 +/- 1.66mug/cm(2)/h, 8.93 +/- 0.55 x10(-3) cm/h, and 2.17 +/- 0.29h, respectively, across rat skin pretreated with microneedle (Dermaroller((R))). Pharmacodynamic study showed prolonged and better management of hypertension after the application of transfersomes gel in experimentally induced hypertensive Wistar rats as compared with oral control formulation. The in vivo angiotensin II type-1 blocking efficacy of prepared transfersomes gel and control formulation was also supported with RT-PCR and western blot analysis of AT1R mRNA and protein expressions on smooth vascular muscles of aorta. Skin irritation and skin histological assessment showed that the prepared transfersomes Carbopol((R)) gel was safe to be used for transdermal route. It is concluded that the incorporation of transfersomes into gel formulation offered enhanced skin contact, ease of application, and found to be a suitable drug reservoir for the transdermal delivery of EM for the management of hypertension in Wistar rats.
