Many antiepileptic drugs (AEDs) are extended-release (ER) tablets, such that an entire day’s dose is taken only once or twice daily. A patient taking four levetiracetam ER 500 mg tablets twice daily was alarmed when, after switching from a generic manufactured by Sun to a generic manufactured by Lupin, ER tablet remnants appeared as intact tablets in his stool, suggesting no drug was absorbed. ...

in this study, attempts were made to evaluate the effect of various acrylic acid based carbopols on the release profile of a beta-adrenoreceptor blocking drug, propranolol hcl, from matrix-type tablets invitro. for this purpose, tablets containing 160 mg of propranolol hcl along with various amounts of carbopols 934 (c934), 971 (c971), 974 (c974) and pemulen (pem) were prepared using the wet gr...

The goal of this study was to compare the pharmacokinetics of nicardipine hydrochloride orally disintegrating tablets and β-cyclodextrin inclusion complex with its conventional tablets. Forty-five rats were divided into three groups evaluating the effect of dosage forms on the pharmacokinetics of nicardipine hydrochloride. Blood samples were taken at predefined sampling points 0–24h after medic...

OBJECTIVES Levocetirizine HCl, a second-generation piperazine derivative and H1-selective antihistaminic agent, possesses few side effects. The first objective of the study was to compare and evaluate the taste-masking effect of different ratios of 2-hydroxypropyl-β-cyclodextrin and mannitol on levocetirizine HCl using an inclusion complex and solid dispersion, respectively. The second objectiv...

The objective of the present investigation was to evaluate potential of nanoemulsions as a coating material for the tablets. The nanoemulsion of size less than 100 nm was prepared using a simple and low-energy spontaneous emulsification method. Conventional tablets containing theophylline as a model hydrophilic drug were prepared. The theophylline tablets were coated with the nanoemulsion using...

The objective of the present study is to formulate and evaluate roxithromycin tablets employing roxithromycin (ROX) solid dispersions. Dispersions of ROX in mannitol were prepared by different techniques like physical mixing, melting method, melt solvent method, kneading technique and common solvent method with drug and carrier ratio of 1:1, 1:2, 1:4 and 1:9. ROX tablets were formulated employi...

this study was performed to design bilayer regioselective floating tablets of atenolol and lovastatin to give immediate release of lovastatin and sustained release of atenolol. bilayer floating tablets comprised two layers, i.e immediate release and controlled release layers. the immediate release layer comprised sodium starch glycollate as a super disintegrant and the sustained release layer c...

Mobility as a Service (MaaS) applies the everything-asa-service paradigm of Cloud Computing to transportation: a MaaS provider offers to its users the dynamic composition of solutions of different travel agencies into a single, consistent interface. Traditionally, transits and data on mobility belong to a scattered plethora of operators. Thus, we argue that the economic model of MaaS is that of...
