the purpose of the research was to formulate microspheres of acyclovir (acv) using mucoadhesive polymers, sodium alginate and chitosan. calcium chloride was used as the ionotropic gelling agent. sodium alginate was crosslinked by calcium chloride leading to a slower release of the drug. chitosan which is a cationic polymer interacted with sodium alginate, an anionic polymer, to form an interpol...

bioassays were conducted to assess the contact toxicity of two plant essential oils against adults of sitophilus granarius (l.) and tribolium confusum jacquelin du val. essential oils were extracted from seeds of carum copticum l. and cuminum cyminum l. contact toxicity was assessed by topical application and adult mortality was counted 1, 2, 6 and 24 h after exposure. bioassays were carried ou...

the topical delivery of non-steroidal anti-inflammatory drugs (nsaids) such as ibuprofen has been explored as a potential method of avoiding the first pass effects and the gastric irritation, which may occur when used orally. ibuprofen is formulated into many topical preparations to reduce the adverse effects and simultaneously avoid the hepatic first-pass metabolism as well. however, it is dif...

the objective of this study was to determine the effectiveness of topical administration of honey in prevention of or reduction in post-surgical peritoneal adhesions in dog. the study was conducted on 18 adultfemale mixed-breed dogs with a mean ± sd weight of 20 ± 4.25 kg. a standardized surgical trauma (serosaltrauma model) was made in the dogs’ descending colon to induce adhesion formation. t...

purpose: to present two patients with acute corneal hydrops, superimposed with infectious keratitis using topical steroids. patients and findings: the first case was a 44-year-old man with acute corneal hydrops in his left eye which was on topical steroids for one week. visual acuity was hand motion at presentation and there was a large epithelial defect with stromal infiltration and corneal ed...

background: lidocaine is a local anesthetic and antiarrhythmic agent. there are reports on accidental and intentional cases of poisoning following injection of lidocaine while rare are the fatal cases realized after oral ingestion of lidocaine. suicidal poisoning with lidocaine pharmaceutical formulations is rare since no pharmaceutical dosage forms for oral use are available except gels and sp...

b a ckground: the present study was designed to investigate the insecticidal efficacy of four different classes of in-secticides: pyrethroids, organophosphates, phenyl-pyrazoles and neo-nicotenoids. one representative chemical from each class was selected to compare the toxicity: deltamethrin from pyrethroids, dichlorovinyl dimethyl phosphate (ddvp) from organophosphates, fipronil from phenyl-p...

topical and transdermal drug delivery systems are noninvasive and can be self-administered with the minimization of side-effects, have received increased attention during the past few years. nanoemulsions, emulsions sized between 20-200 nm with narrow distributions, offer several advantages for topical and transdermal delivery of pharmaceutical agents including controlled droplet size, the abil...

Background: This two-arm, randomized clinical study aimed to compare efficacy between topical Alpha ointment and topical hydrocortisone cream (1%) in the healing of radiation-induced dermatitis in breast cancer patients. Methods: The inclusion criteria comprised newly pathologically proven, locally advanced breast cancer (treated with modified radical mastectomy followed by sequential adjuvant ...
