General description

Oxyphenbutazone is a derivative compound of phenylbutazone.

Biochem/physiol Actions

Oxyphenbutazone is a non-steroid anti inflammatory; anti Mycobacterium tuberculosis agent. Oxyphenbutazone is known to cause inflammatory effects on tissues. Oxyphenbutazone, as a drug, decreases cellular exudates, without involving the pituitary-adrenal axis or the immunity response. Though the drug delivers a number of side effects, it is considered to be less toxic than phenylbutazone, due to decreased rate of intestinal absorption.
Oxyphenbutazone is an NSAID that has been shown to preferentially kill non-replicating Mycobaterium tuberculosis maintained in media that simulates the mildly acidic, in vivo conditions where drug-resistant, non replicating subpopulations of the bacteria reside in hosts. The compound has little or no affect on replication M. tuberculosis grown in normal liquid cultures.
