Chromatographic study of sitagliptin and ertugliflozin under quality-by-design paradigm

Abstract The present study entails the systematic development and validation of a stability-indicating RP-HPLC method for the analysis of sitagliptin and ertugliflozin in a fixed-dose combination. Analytical quality by design (AQbD) concepts were used to define critical method variables, employing Pareto...

Preparation and evaluation of 2-methoxyestradiol-loaded pH-sensitive liposomes

The development and clinical application of 2-methoxyestradiol (2-ME) as a new type of antitumor drug are limited due to its poor solubility, rapid metabolism in vivo, and large oral dosage. 2-ME-loaded pH-sensitive liposomes (2-ME-PSLs) was prepared containing the lipids, Lipoid E-80 (E-80), cholesteryl...

Effect of pH on weakly acidic and basic model drugs and determination of their ex vivo transdermal permeation routes

ABSTRACT The aim of the present study was to investigate the effect of donor pH on the transdermal permeability of the model drugs across rat skin and also to determine the major route of transport of the drugs. Weakly acidic drugs (partition coefficient) ibuprofen (3.6), aceclofenac (3.9), glipizide (1....

Análise dos efeitos colaterais provocados pelo uso da acetazolamida via oral nos primeiros 5 dias de tratamento com relaçäo aos níveis séricos de potássio
Side effects of acetazolamide per os during the first five days of treatment and relationship with seric potassium level

Arq. bras. oftalmol; 56 (3), 1993
Os autores realizaram um estudo duplo-cego para determinar uma possível entre potássio sérico e efeitos colaterais, que aparecem nos primeiros 5 dias de tratamento com acetazolamida 500 mg, via oral. Em todos aqueles que usaram a droga produziu-se efeitos colaterais, sendo o mais comum parestesias. NÃ...
