Background and purpose: Oral route is the most frequently used route for drug administration and tablets are the most popular oral drug forms. The study of drug-excepient compatibility is an important process in development of a stable solid dosage form. Incompatibility between drugs and excipients can alter the stability and bioavailability of drugs, thereby affecting its safety and/or efficac...
Antibacterial drugs used in animal might result in deposition of residues in meat, milk and eggs. The presence of antimicrobial residues in animal-originated food is critical problem in many countries over the years. Because, drug residues might result in various health hazards, both actual incidence of reactions and potential hazards perceived by the public, the most countries assess residue o...
Linear–dendrite copolymers containing hyper branched poly(citric acid) and linear poly(ethylene glycol) blocks PCA–PEG–PCA are promising nonmaterial to use in nanomedicine. To investigate their potential application in biological systems (especially for drug carries) ONIOM2 calculations were applied to study the nature of particular interactions between drug and the polymeric nanoparticle...
estimation of protein stability is important for many reasons: first providing an understanding of the basic thermodynamics of the process of folding, protein engineering, and protein stability plays important role in biotechnology especially in food and protein drug design. today, proteins are used in many branches, including industrial processes, pharmaceutical industry, and medical fields. a...
an oral sustained-release floating tablet formulation of metformin hcl was designed and developed. effervescence and swelling properties were attributed on the developed tablets by sodium bicarbonate and hpmc-peo polymer combination, respectively. tablet composition was optimized by response surface methodology (rsm). seventeen (17) trial formulations were analyzed according to box-behnken desi...
An oral suspension could a suitable dosage form for the geriatric patients. The calcium alginate coated ion exchange resinate of propranolol hydrochloride were prepared using Amberlite IR-120 by solvent evaporation. Microcapsules of propranolol hydrochloride resinate were prepared by solvent evaporation technique,the suspensions were prepared by using deionised water as the vehicle. Methy...
Exposure of a drug to irradiation can influence the stability of the formulation, leading to changes in the physicochemical properties of the product. The influence of excipients of frequently used stabilizers is often difficult to predict and, therefore, stability testing of the final preparation is important. The selection of a protective packaging must be based on knowledge about the wavelen...
Promethazine hydrochloride, a 5-HT3 antagonist is a powerful antiemetic drug with an oral bioavailability of 25% due to extensive hepatic first pass metabolism and is extremely bitter in taste. To overcome the above draw backs, the present study was carried out to formulate and evaluate fast dissolving taste masked wafers of Promethazine hydrochloride for sublingual administration. Taste maskin...
Background and purpose: The dissolution of a drug has a major role on its bioavailability. Any change in physico-chemical properties can result in changes in drug release, and furthermore in its bioavailability. Evidence suggest that physicochemical properties of medicinal solids depend on the presence of heat and humidity. In order to overcome such changes, it is necessary to determine the sto...
