Biotransformation of diclofenac sodium (Voltaren) in animals and in man. I. Isolation and identification of principal metabolites.

1. The anti-inflammatory agent diclofenac sodium (o-[(2,6-dichlorophenyl)amino]phenylacetic acid sodium salt) is extensively metabolized by rat, dog, baboon and man. The main metabolites were isolated from the urine of all species and from the bile of rat and dog and identified by spectroscopy. 2. Metabolism involves direct conjugation of the unchanged drug, or oxidation of the aromatic rings usually followed by conjugation. Sites of oxidation are either position 3' or 4' of the dichlorophenyl ring or, alternatively, position 5 of the phenyl ring attached to the acetic acid moiety. 3. In the urine of rat, baboon and man conjugates of the hydroxylated metabolites predominate, but the major metabolite in dog urine is the taurine conjugate of unchanged diclofenac. 4. In the bile of rat and dog, the main metabolite is the ester glucuroniade of unchanged diclofenac.

Biotransformation of diclofenac sodium (Voltaren) in animals and in man. II. Quantitative determination of the unchanged drug and principal phenolic metabolites, in urine and bile.

1. Quantitative determinations of unchanged diclofenac and two of its major phenolic metabolites were made by reverse isotope dilution analysis on urine of rat, dog, rhesus monkey, baboon and man and on bile of rat, dog and man. Isotope dilution analysis was performed before and after various methods of enzymic and chemical hydrolysis. 2. The same samples were also analysed by two-dimensional t.l.c. and subsequent autoradiography, to estimate the remaining phenolic metabolites. 3. In contrast to rat, rhesus monkey, baboon and man, which excrete mainly hydroxylated metabolites, the dog does not oxidize diclofenac. Dog urine contained a relatively stable taurine conjugate of diclofenac, and in the bile an ester glucuronide was excreted, which decomposed even in weakly alkaline soln. 4. The unstable ester glucuronide found in dog bile was also demonstrable in rat bile. It presumably hydrolyses in the duodenum, releasing diclofenac which undergoes enterohepatic circulation.

The dynamics of owning and disowning: psychoanalytic and family perspectives.

The dynamics of owning and disowning one's inner life have both intrapsychic and transactional or interpersonal dimensions. Freud opened new vistas on our inner world using psycoanalysis as a tool. Although not unaware of the effects of family members upon each other, Freud's rejection of the seduction theory of neurosis in 1897 fatefully influenced the future course of psychoanalysis, placing the primary focus on intrapsychic relations. Until today, it has remained the task-perhaps the principal one--of psychoanalytic theorists to do justice to the interpersonal and family realm that Freud neglected, without sacrificing the enormous insights we owe to Freud. Three conditions for successful inner ownership are described: a capacity for self-object differentiation; tolerance of ambivalence; and a sense of physical integrity, of having a cohesive, nuclear ego. The pathology of inner ownership is related to a pathology of interpersonal ownership as transacted on the family level. One form of such relational pathology--parental overowning, as revealed primarily in families with schizophrenic members--is discussed, with a case example.
