Improved high-performance liquid chromatographic procedure for the determination of tetracyclines in plasma, urine and tissues. 1978

J P Sharma, and R F Bevill

An improved extraction procedure for the determination of oxytetracycline, tetracycline and chlortetracycline in urine, plasma and tissues by high-performance liquid chromatography is described. The addition of phenylbutazone (3,5-dioxo-1,2-diphenyl-4-n-butylpyrazolidine) to water, urine or plasma enhances the extraction of these compounds by ethyl acetate. The recovery of oxytetracycline from plasma is increased six fold and the need for two separate extractions of urine and plasma is eliminated. The formation of phenylbutazone-tetracycline ion pairs and their role in the extraction process is discussed.

D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D013552	Swine	Any of various animals that constitute the family Suidae and comprise stout-bodied, short-legged omnivorous mammals with thick skin, usually covered with coarse bristles, a rather long mobile snout, and small tail. Included are the genera Babyrousa, Phacochoerus (wart hogs), and Sus, the latter containing the domestic pig (see SUS SCROFA).

D013754	Tetracyclines	Closely congeneric derivatives of the polycyclic naphthacenecarboxamide. (Gilman et al., Goodman and Gilman's The Pharmacological Basis of Therapeutics, 8th ed, p1117)
D014018	Tissue Distribution	Accumulation of a drug or chemical substance in various organs (including those not relevant to its pharmacologic or therapeutic action). This distribution depends on the blood flow or perfusion rate of the organ, the ability of the drug to penetrate organ membranes, tissue specificity, protein binding. The distribution is usually expressed as tissue to plasma ratios.	Distribution, Tissue,Distributions, Tissue,Tissue Distributions
