Eighty-two-year-old patient with a pacemaker using warfarin due to arrhythmia and having an intraocular lens in the right eye, developed spontaneous hemorrhagic choroidal detachment one day after the use of combined preparation of 0.5% timolol maleate and 0.004% travoprost, due to primary open-angle glaucoma. Hemorrhagic detachment was detected by anterior and posterior segment examination, as ...

Department of Pharmaceutical Technology, Meerut Institute of Engineering & Technology, NH-58, Baghpat Road-Bypass Crossing, Meerut-250005 (U.P), India ABSTRACT Drug release from mucoadhesive patches at predetermined rate in oral cavity having distinct advantages over traditional dosage forms as tablets, gels and solutions. This review provides brief information about method of preparation and e...

Aim: The objective of the present study is to design and evaluate mucoadhesive microspheres for oral controlled release. Materials and Method: Rosiglitazone maleate microspheres with a coat consisting of alginate and a mucoadhesive polymer sodium carboxymethylcellulose, carbopol 934P and hydroxypropylmethylcellulose were prepared by an orifice-ionic gelation process. The microspheres were evalu...

In the present study a series of 1-substituted-4-(2-methoxyphenyl)-s-triazolo[4,3-a]quinazolin-5(4H)-ones were synthesized and are screened for their H1-antihistaminic activity. The synthesized compounds were characterized by IR, H-NMR and mass spectral data; the purity of the compounds was determined by elemental analysis. Antihistaminic activity of the title compounds was evaluated by histami...

Boric acid-pyridine mixture is presented as mild catalyst for polycondensation of semi-esters of ethylene glycol, in situ-generated by “cyclic anhydrideediol” reaction scheme from maleic, succinic and phthalic anhydrides. This catalyst system was demonstrated to give colorless polyesters in low molecular weights (Mn: 1650e1950 Da) within 4 h at 130 C 1H NMR spectra of the polyesters derived fro...

The effects of topical timolol maleate 0.5% on the ophthalmic artery diastolic (OABPd), systolic (OABPs) and mean blood pressure (OABPm) were investigated in 19 healthy subjects using compression ophthalmodynamometry. In a randomized, double-blind study, one eye of each subject received one drop of timolol maleate 0.5% and the fellow eye received a drop of placebo. Measurements of OABPd and OAB...

Purpose: To synthesize a new series of 1-substituted-4-(pyridin-4-yl) [1,2,4] triazolo[4,3-a]quinazolin5(4H)-ones and evaluate them for H1-antihistaminic activity with negligible side effects in guinea pigs. Methods: The synthesized compounds were characterized by Infrared spectroscopy (IR), proton nuclear magnetic resonance (H-NMR) and mass spectrometry (MS) data. The purity of the compounds w...

A series of novel 4-(3-ethylphenyl)-1-substituted-4H-[1,2,4] triazolo[4,3-a]quinazolin-5-ones (4a-j) were synthesized by the cyclization of 3-(3-ethylphenyl)-2-hydrazino-3H-quinazolin-4-one (3) with various one-carbon donors. The starting material, compound 3, was synthesized from 3-ethyl aniline by a new innovative route with improved yield. When tested for their in vivo H1-antihistaminic acti...
