Abstract

Çağın
giderek yaygınlaşan hastalıklarından biri alerjik rinittir. Alerjik rinitin
tedavisinde öncelikle alerjenlerden kaçınma ve ilaç tedavisi kullanılır. İlaç
olarak daha çok alerjenin etkisini azaltan antihistaminikler kullanılır. Bu
sebeple son yıllarda bu ilaçların çözünürlük, biyolojik aktivite, absorpsiyon,
lipofilik etkileri ve iyonlaşma sabitleri gibi fizikokimyasal parametreleri,
yan etkileri ve ilaç etkileşimleri daha kapsamlı araştırılmaktadır. İyonlaşma
sabiti (pKa) bir molekülün iyonlaşmış ve iyonlaşmamış formlarının
birbirine eşit olduğu pH değeridir. pKa değeri ilaç absorbsiyonunu
etkiler. İlaçların çoğu suda çözünürlüğü az olan moleküller olduğu için iyonlaşma
sabitlerinin tayinlerinde su-organik çözücü ikili karışımları kullanılır. Bu
çalışmada loratadin ve desloratadin’in su-asetonitril çözücü karışımında
iyonlaşma sabiti değerleri HPLC yöntemiyle tayin edilmiştir. Non lineer
regresyon programı (NLREG) kullanılarak elde edilen pKa
değerlerinden Mol kesri-pKa yöntemi ve Yasuda-Shedlovsky ekstrapolasyon
yöntemiyle sudaki pKa değerlerine geçilmiştir. Elde edilen verilerin
bilgisayar programı ile hesaplanan verilerle uyum içerisinde olduğu
gözlenmiştir.

Determination of Ionization Constants of Loratadine and Desloratadine by HPLC Method

Abstract

One of
the increasingly common diseases of the age is allergic rhinitis. In the
treatment of allergic rhinitis, primarily allergens and drug treatment are
used. Antihistamines are used to reduce the effect of allergens. Therefore, physicochemical parameters,
side effects and drug interactions such as solubility, biological activity,
absorption, lipophilic effects and ionization constants of these drugs have
been investigated in recent years. The ionization constant (pKa)
is the pH at which the ionized and non-ionized forms of a molecule are equal to
each other. pKa value affects the drug absorption. Because most of
the drugs are low water-soluble
molecules, water-organic solvent binary mixtures are used in the
determination of ionization constants. In this study, ionisation constant
values ​​of loratadine and desloratadine in water-acetonitrile solvent were
determined by HPLC method. The pKa values ​​obtained by using non
linear regression program (NLREG) were changed to aqueous pKa values
by means of Mole
fraction-pKa method and Yasuda-Shedlovsky extrapolation method. It
was observed that the data obtained were in harmony with the data calculated by
the computer program.
