AB  - With the development of physiologically based absorption models, there is an increased scientific and regulatory interest in in silico modelling and simulation of drug-drug and drug-food interactions. Clinically significant interactions between ciprofloxacin and metallic compounds are widely documented. In the current study, a previously developed ciprofloxacin-specific in silico absorption model was employed in order to simulate ciprofloxacin/metallic compound interaction observed in vivo. Commercially available software GastroPlus (TM) (Simulations Plus Inc., USA) based on the ACAT model was used for gastrointestinal (GI) simulations. The required input parameters, relating to ciprofloxacin hydrochloride physicochemical and pharmacokinetic characteristics, were experimentally determined, taken from the literature or estimated by GastroPlus (TM). Parameter sensitivity analysis (PSA) was used to assess the importance of selected input parameters (solubility, permeability, stomach and small intestine transit time) in predicting percent drug absorbed. PSA identified solubility and permeability as critical parameters affecting the rate and extent of ciprofloxacin absorption. Using the selected input parameters, it was possible to generate a ciprofloxacin absorption model, without/with metal cation containing preparations co-administration, which matched well the in vivo data available. It was found that reduced ciprofloxacin absorption in the presence of aluminium hydroxide, calcium carbonate or multivitamins/zinc was accounted for by reduced drug solubility. The impact of solubility-permeability interplay on ciprofloxacin absorption can be observed in the ciprofloxacin-aluminium interaction, while in ciprofloxacin-calcium and ciprofloxacin-zinc interactions, effect of solubility was more pronounced. The results obtained indicate that in silico model developed can be successfully used to complement relevant in vitro studies in the simulation of physicochemical ciprofloxacin/metallic compound interactions.

AB  - Ciprofloxacin bioavailability may be reduced when ciprofloxacin is co-administered with metallic ion containing preparations. In our previous study, physicochemical interaction between ciprofloxacin and ferrous sulphate was successfully simulated in vitro. In the present work, comparative in vitro ciprofloxacin solubility and dissolution studies were performed in the reactive media containing aluminium hydroxide, calcium carbonate or zinc sulphate. Solid phases collected from the dissolution vessel with aluminium hydroxide, calcium carbonate and zinc sulphate were investigated for their properties. The results obtained indicate that different types of adducts may form and retard ciprofloxacin solubility and dissolution. In the case of aluminium, no phase changes were observed. The solid phase generated in the presence of calcium carbonate was identified as hydrated ciprofloxacin base. Similarly to iron, a new complex consistent with Zn(SO4)(2)(Cl)(2)(ciprofloxacin)(2) x nH(2)O stoichiometry was generated in the presence of relatively high concentrations of ciprofloxacin hydrochloride and zinc sulphate, indicating that small volume dissolution experiments can be useful for biorelevant dissolution tests.

AB  - The ciprofloxacin-iron interaction, resulting in a lower bioavailability, is well documented in vivo; however, a mechanistic explanation supported by experimental data of this interaction is missing. In the present study, ciprofloxacin hydrochloride (HCl) and ferrous sulfate interaction was simulated in vitro by performing solubility and dissolution studies in the reactive media containing ferrous sulfate. Characterization of the precipitate formed indicated its probable chemical structure as Fe(SO(4)(2-))(2)(Cl(-))(2)(ciprofloxacin)(2) x (H(2)O)(n), where n is up to 12 molecules of water. The solubility of this complex in water was estimated to be approximately 2mg/mL, being about 20-fold lower than the solubility of ciprofloxacin HCl. The solubility of the complex was used as input parameter for an in silico modeling by GastroPlus (TM) and the resulting predicted plasma time curves were in good agreement with the in vivo data. These results strongly indicate that ciprofloxacin-iron interaction in vivo is caused by the formation of a low soluble complex. This interaction was also simulated by in vitro dissolution, in which a mini scale apparatus provided more biorelevant results than the standard dissolution apparatus, probably because the drug concentrations in the mini apparatus were higher and, thus, closer to the conditions encountered in vivo.

AB  - The ciprofloxacin - metallic ions interactions are well documented and described in the literature. In vivo studies show that ciprofloxacin bioavailability is reduced in the presence of metallic ions containing preparations. The results of in vitro studies are somewhat contradictory and indicate that highly soluble complexes, low soluble complexes, or no complexation may occur. Development of relevant simulation softwares resulted in the increased confidence and use of mathematical modeling and simulation in drug development and quality control. Advanced computer software's are now available which simulate drug product pharmacokinetic profile based on its physicochemical properties, formulation characteristics and physiological conditions in the gastrointestinal tract. The aim of the current work is to assess potential causes of reduced ciprofloxacin bioavailability when co-administered with metallic ion containing preparations through survey of the relevant in vivo, in vitro and in silico studies. The results obtained indicate that complex formation is one of the mechanisms involved in ciprofloxacin/metallic ion interaction and that other phenomena such as reduced solubility in the altered pH conditions and/or adsorption on the solid phase present in the intestinal lumen may also play a role. In order to accurately identify mechanisms responsible for drug interaction, thorough evaluation of all the available in vivo, in vitro and in silico data should be performed as part of the biopharmaceutical characterization.
AB  - Interakcija ciprofloksacina i jona metala je dobro poznata i opisana u literaturi. Rezultati in vivo ispitivanja pokazuju da je biološka raspoloživost ciprofloksacina smanjena nakon istovremene primene preparata koji sadrže jone metala. Rezultati in vitro ispitivanja su kontradiktorni i pokazuju da mogu nastati kompleksi koji imaju veću rastvorljivost u odnosu na polazno jedinjenje, da nastali kompleksi imaju smanjenu rastvorljivost, kao i da građenje kompleksa izostaje. Sa razvojem računarskih programa koji omogućavaju predviđanja farmakokinetičkog profila na osnovu fizičko-hemijskih karakteristika lekovite supstance, karakteristika formulacije i fizioloških uslova u gastrointestinalnom traktu, matematičko modelovanje i simulacije zauzimaju sve važnije mesto u razvoju i proceni kvaliteta lekova. Cilj rada je da se kroz pregled rezultata in vivo, in vitro i in silico studija, analiziraju potencijalni uzroci promene u bioraspoloživosti ciprofloksacina primenjenog sa preparatima koji sadrže jone metala. Dobijeni rezultati ukazuju da građenje kompleksa predstavlja jedan od mehanizama uključenih u in vivo interakciju ciprofloksacina i jona metala i da drugi faktori, kao što je smanjena rastvorljivost usled promene pH i/ili adsorpcija na nerastvorene komponente čvrste faze, takođe mogu uticati. U okviru biofarmaceutske karakterizacije interakcija lekova, potrebno je uzeti u obzir rezultate in vivo, in vitro i in silico ispitivanja i sprovesti njihovu sveobuhvatnu analizu radi utvrđivanja mehanizma interakcije.

Cilj rada je da se kroz pregled rezultata in vivo, in vitro i in silico studija, analiziraju potencijalni uzroci promene u bioraspoloživosti ciprofloksacina primenjenog sa preparatima koji sadrže jone metala. Dobijeni rezultati ukazuju da građenje kompleksa predstavlja jedan od mehanizama uključenih u in vivo interakciju ciprofloksacina i jona metala i da drugi faktori, kao što je smanjena rastvorljivost usled promene pH i/ili adsorpcija na nerastvorene komponente čvrste faze, takođe mogu uticati. U okviru biofarmaceutske karakterizacije interakcija lekova, potrebno je uzeti u obzir rezultate in vivo, in vitro i in silico ispitivanja i sprovesti njihovu sveobuhvatnu analizu radi utvrđivanja mehanizma interakcije.",
