Doel van de analyse

Het doel van de analyse is om de hoeveelheid farmacon in de gemaakte
zetpillen te onderzoeken en te controleren.



Eigenschappen analieten




Figuur 1 Mesalazine




Eigenschap Waarde Bron

Oplosbaarheid slightly soluble in water (1 Analytical Profiles
mg/mL at 20°C) of Drug Substances
and Excipients
soluble in dilute hydrochloric
acid and in dilute alkali
hydroxides

Very slightly soluble in
dehydrated alcohol, acetone,
and methyl alcohol, and
practically insoluble in
chloroform, ether, butyl
alcohol, ethyl acetate, n-
hexane, methylene chloride,
and propyl alcohol

The aqueous solubility of
mesalamine has been reported
to be 0.844 mg/mL at 25°C,
and 1.41 mg/mL at 37°C

Pka 6,0 (aminogroep)

3,0 ( carboxylgroep)

13,9 (hydroxylgroep)

Log P 0.46 ± 0.34

, pH-shift in UV/Vis

Stabiliteit De ontleding van mesalamine Analytical Profiles
in de oplossingsfase vindt snel of Drug Substances
plaats onder omstandigheden and Excipients
die oxidatie bevorderen, en de
verbinding is het meest
stabiel onder omstandigheden
die de neiging hebben oxidatie
te remmen.
Decarboxylering bleek geen
significante afbraakroute te
zijn. Ze gaven verder aan dat
deze verbinding een oxidatie
van twee elektronen en twee
protonen ondergaat, met de
vorming van 5-
aminosalicylzuurchinoneimine


mesalamine is vrij stabiel in
tablet- en zetpilformuleringen.
Studies hebben aangetoond
dat minder dan 1% afbraak
van het medicijn plaatsvond in
deze doseringsvormen na
opslag bij kamertemperatuur
gedurende een jaar
