Objectives: The aim of the present study was to formulate and characterize solid lipid nanoparticles (SLNs) of essential oil of Zataria multiflora. Methods: The essential oil was extracted from the leaves of Z. multiflora and was analyzed by GC-MS. SLNs were prepared using two methods including precipitation technique and hot homogenization method for achieving the best encapsulation. The SLNs were characterized by Read More

Pharmacokinetic parameters of ketorolac tromethamine (KT) loaded albumin (KTAL) microspheres were determined using New Zealand white rabbits. Each rabbit (n=6) was injected 5 mg/kg body weight of plain KT or an equivalent dose in microsphere form in 2 mL water for injection. Prior to animal studies microspheres were tested for toxic residues and were gamma sterilized. Sterilized microspheres were evaluated for th Read More

The aim of the present investigation was to prepare coumarin matrix transdermal systems using the combinations of Eudragit RL-100/Eudragit RS-100. The formulations were evaluated for various physicochemical properties (thickness, weight variation, drug content uniformity, moisture content and water absorption uptake), in vitro release studies, in vitro skin permeation studies and skin irritation studies. In vitro skin per Read More

The present studies entail the formulation development and evaluation of chronomodulated drug delivery system of amoxicillin trihydrate (AMT), which comprises of a bilayer tablet containing a delayed release and a sustained release layer. Direct compression method was employed for the preparation of bilayer matrix tablets containing rational blend of polymers, such as Eudragit-L100 D55 as delayed release polymer and Read More

Periodontitis is an inflammatory condition affecting teeth resulting in progressive destruction of periodontal ligaments, resorption of alveolar bone and loss of teeth. Treatment of periodontitis includes surgical and non surgical management. Systemic antibiotics are also used for the treatment of periodontitis. The aim of this research was to formulate smart gel system of azithromycin (AZT) and to evaluate in vitro and in vivo for n Read More

Mucilages, and in particular plant mucilages, have gained more attention over the last few decades due to their reputable medicinal properties. Some publications have appeared in reputable Scientific Journals that have made appreciable contributions to the discovery of the functions and utilizations of such naturally occurring products. Therapeutic value of mucilages has been extended to wound healing, diabetes, immuno Read More

The development of the vectorized delivery systems combining advantages of the colloidal carriers, with active targeting to the receptors sites suggests that nanoparticles have a considerable potential for treatment after biophase internalization and pharmacokinetics, as for example gene therapy. Two major mechanisms can be distinguished for addressing the desired sites for drug release: (i) passive and (ii) active targetin Read More

The present study deals with preparation, optimization and in-vitro drug release study of hydroxyapatite (HAp)- ofloxacin for bone-implantable delivery in osteomyelitis treatment. The effect of drug amount added, and orthophosphoric acid addition rate as process parameters on the drug loading into HAp-system by precipitation method was optimized by using 32 factorial design. The response surface methodology utilizing Read More
