Description

Oxybuprocaine (benoxinate) hydrochloride (MINIMS®) is a local, surface anaesthetic of the ester type. It has been shown to give effective surface anaesthesia in short opthalmological procedures. Sensation of pain is locally and reversibly reduced, with the possibility of temperature and pressure sensitivity also affected. Anaesthetic activity is ten times that of cocaine and twice that of tetracaine (amethocaine). Oxybuprocaine (benoxinate) binds to sodium channel and reversibly stabilizes the neuronal membrane which decreases its permeability to sodium ions. Depolarization of the neuronal membrane is inhibited thereby blocking the initiation and conduction of nerve impulses.

Sample Use Guides

In Vivo Use Guide
One drop of MINIMS® instilled into each eye has been shown sufficient for tonometry after one minute. Addition of a further drop after 90 seconds provides adequate anaesthesia for fitting of a contact lens. To obtain a deeper anaesthetic effect, further drops may be instilled at intervals of no less than 90 seconds. For most procedures one to two drops is sufficient, however for removal of foreign bodies or minor surgery, three to six drops is suggested.
Route of Administration: Topical ophthalmic
In Vitro Use Guide
The cytotoxic effect of oxybuprocaine (OBPC) on human corneal epithelial (HCEP) cells was characterized and its possible cellular and molecular mechanisms was investigated using an in vitro model of non-transfected HCEP cells. The results showed that OBPC at concentrations ranging from 0.025% to 0.4% had a dose- and time-dependent cytotoxicity to HCEP cells. Moreover, OBPC arrested the cells at S phase and induced apoptosis of these cells by inducing plasma membrane permeability, phosphatidylserine externalization, DNA fragmentation, and apoptotic body formation. Furthermore, OBPC could trigger the activation of caspase-2, -3, and -9, downregulate the expression of Bcl-xL, upregulate the expression of Bax along with the cytoplasmic amount of mitochondria-released apoptosis-inducing factor, and disrupt mitochondrial transmembrane potential.
