Abstract
Furosemide and torasemide (loop diuretics) are used to treat hypertension or pulmonary edema. They are often administered in the parenteral route. In critically ill patients, there is a problem of a limited number of venous accesses, which complicates the polytherapy. Drugs of unknown compatibility must be administered separately, and the problem increases in patients receiving parenteral nutrition. Lipid emulsions have been introduced into clinical practice as a high-calorie, non-glucose source of energy for parenteral administration, but they can also be used as lipophilic drug carriers. In this paper, the parenteral nutrition admixture (PNA) Nutriflex Lipid special was used as a drug carrier for furosemide and torasemide. For this purpose, drug stability tests (HPLC method) were carried out in various light and temperature conditions, imitating clinical conditions, and the parameters of the lipid emulsion (pH, zeta potential, the size of the emulsion droplets and polpolydispersity) were tested. Furosemide and torasemide added to Nutriflex Lipid special did not cause significant changes in the physicochemical properties of PNA. Changes in pH and MDD were within acceptable limits. Both drugs when added to Nutriflex Lipid special were degraded, dependent on the storage conditions and the chemical structure.
期刊介绍:
The international journal of the Polish Pharmaceutical Society is published in 6 issues a year. The journal offers Open Access publication of original research papers, short communications and reviews written in English, in all areas of pharmaceutical sciences. The following areas of pharmaceutical sciences are covered: Analysis, Biopharmacy, Drug Biochemistry, Drug Synthesis, Natural Drugs, Pharmaceutical Technology, Pharmacology and General.
A bimonthly appearing in English since 1994, which continues “Acta Poloniae Pharmaceutica”, whose first issue appeared in December 1937. The war halted the activity of the journal’s creators. Issuance of “Acta Poloniae Pharmaceutica” was resumed in 1947. From 1947 the journal appeared irregularly, initially as a quarterly, then a bimonthly. In the years 1963 – 1973 alongside the Polish version appeared the English edition of the journal. Starting from 1974 only works in English are published in the journal. Since 1995 the journal has been appearing very regularly in two-month intervals (six books a year). The journal publishes original works from all fields of pharmacy, summaries of postdoctoral dissertations and laboratory notes.
