Lisinopril is an angiotensin-converting enzyme (ACE) inhibitor, primarily used for the treatment of hypertension, congestive heart failure, and heart attack. It belongs to BCS class III having a half-life of 12 hrs and 25% bioavailability. The purpos...
A highly water-soluble macromolecular compound of ursolic acid with mono-methoxypoly(ethylene glycol) (mPEG) was prepared. The physicochemical properties and stabilities under different conditions were investigated. By PEG conjugation, greatly increa...
This is a corrigendum to the article 'Inhibition of Key Digestive Enzymes Related to Diabetes and Hyperlipidemia and Protection of Liver-Kidney Functions by Trigonelline in Diabetic Rats' [Sci Pharm. 2013; 81: 233–246]. Figure 6 is replaced.
Natural gums are economical, easily available, and useful as tablet binders. In the present investigation, an attempt was made to formulate Ofloxacin tablets using three natural binders, namely Acacia arabica, Hibiscus esculentus, and xanthan gum. Su...
The aim of the current study was to develop a simple, precise, and accurate capillary zone electrophoresis method for the determination of zolpidem tartrate in tablet dosage form. Separation was conducted in normal polarity mode at 25°C, 22 kV, using...
Objective: To evaluate the antihypercholesterolemic effects of 50 mg/kg BW and 100 mg/kg BW per day of an ethanolic extract of Crotalaria juncea Linn (whole plant) by performing in vivo studies. Methods: The effects of oral administration of 50 mg/...
Osteocare, a herbal formulation, has been found to be very effective in bone mineralization and support of the microstructure of bone tissue. The water-soluble components of Osteocare (WSCO) induced osteogenic activity in human osteoblast-like SaOS-2...
Statistical experimental design was used to optimize the chromatographic separations of two pharmaceutical compounds from their respective potential impurities. A fractional factorial design was utilized to study the effects of pH, organic solvent in...
A robust, sensitive, and stability-indicating rapid resolution liquid chromato-graphy method for the simultaneous determination of process impurities and degradation products of lercanidipine hydrochloride in pharmaceutical dosage form was developed...
The antimicrobial activity of 3-methyl-5-isopropyl (or ethyl) 6-methyl-4-nitro-phenyl-1,4-dihydropyridine-3,5-dicarboxylate derivatives was evaluated. Prokaryotes (bacteria) appeared to be more sensitive to their antimicrobial activity than were euka...
This study details the isolation, identification, and characterization of ambroxol’s unknown impurity. One unknown impurity of ambroxol was formed in the formulated drug under stress conditions [40°C /75% relative humidity (RH) for 6 months] with the...
Sulfasalazine (SSZ) was subjected to degradation under the conditions of hydrolysis (acid, alkali, and water), oxidation (30% H2O2), dry heat, and photo-lysis (UV-VIS light) in accordance with the ICH guidelines. An RP-HPLC method was developed to st...
Human serum albumin (HSA) in the blood binds long-chain fatty acids (LCFAs), and the number of bound LCFAs varies from 1 to 7 depending on the physical condition of the body. In this study, the influence of LCFA-HSA binding on drug-HSA binding was st...
Memantine is chemically a tricyclic amine and is used for Parkinson's disease and movement disorders. Although several HPLC methods with different derivatization reagents have been developed for the determination of memantine in biological fluids, th...
In this stability-indicating, reversed-phase high-performance liquid chromato-graphic method for flupiritine maleate, forced degradation has been employed and the formed degradants were separated on a C18 column with a 80:20% v/v mixture of methanol-...
Disuse by bed rest, limb immobilization, or space flight causes rapid bone loss by arresting bone formation and accelerating bone resorption. Propranolol (a non-selective β-adrenergic antagonist) has been shown to improve bone properties by increasin...
