Use and Manufacturing

【Use and Manufacturing】
Methods of Manufacturing

NEUTRALIZATION OF SODIUM CARBONATE OR SODIUM HYDROXIDE WITH HYDROBROMIC ACID FOLLOWED BY EVAPORATION AND TREATMENT WITH CARBON TO REDUCE THE BROMATE TO BROMIDE
PREPD COMMERCIALLY BY ADDING SOME EXCESS BROMINE TO SODIUM HYDROXIDE SOLN FORMING MIXTURE OF BROMIDE & BROMATE. REACTION PRODUCTS ARE EVAPORATED TO DRYNESS & TREATED WITH CARBON TO REDUCE BROMATE TO BROMIDE. REF: VAN TER MEULEN, US PATENT 1,775,598 (1930); ROBERTSON, IND ENG CHEM 34, 133 (1942)...
MADE SYNTHETICALLY BY FIRST CAUSING IRON TO REACT WITH BROMINE & WATER. RESULTING FERROSO-FERRIC BROMIDE IS DISSOLVED IN WATER, SODIUM CARBONATE ADDED, SOLN FILTERED & EVAPORATED.

Biomedical Effects and Toxicity

【Therapeutic Uses】
DOSE-- USUAL, 900 MG DAILY. DOSAGE FORMS-- ELIXIR.
SODIUM BROMIDE IS A SEDATIVE & HYPNOTIC WHICH IS ONLY EFFECTIVE WHEN USED OVER PERIOD OF TIME. IT IS USELESS AS AN OCCASIONAL HYPNOTIC. IT IS TOO DANGEROUS FOR CONTINUED USE EXCEPT CAUTIOUSLY FOR SELECTED CASES OF GRAND MAL EPILEPSY IN CHILDREN WHICH DO NOT RESPOND TO CONVENTIONAL LESS TOXIC AGENTS.
MEDICATION (VET): RARE, IN CLINICAL VET MEDICINE BUT OCCASIONALLY IN MIXTURE AS IN POTASSIUM FORM... EFFECTIVE WITH EQUAL QUANTITIES OF CHLORAL HYDRATE IN COLICS, AZOTURIA, & TETANY OF HORSES AS WELL AS IN NERVOUS ACETONEMIA OF CATTLE.
SEDATIVE, HYPNOTIC
/PRC: FORMERLY/ MEDICATION (VET): SEDATIVE; HAS BEEN USED TO CONTROL CONVULSIONS, CHOREA, HYSTERIA
【Biomedical Effects and Toxicity】
FOLLOWING ORAL ADMIN, BROMIDE SALTS ARE RAPIDLY ABSORBED FROM LOWER PART OF SMALL INTESTINE. WHEN USED AS SEDATIVE IN ADULTS, THERAPEUTICALLY EFFECTIVE BLOOD LEVEL OF BROMIDES IS 0.5-0.6...(MEQ)/LITER. ... BROMIDE IS WIDELY DISTRIBUTED THROUGHOUT EXTRACELLULAR FLUIDS INCLUDING SECRETIONS & TRANSUDATES. /BROMIDES/
...BROMIDES CROSS THE PLACENTA. RENAL EXCRETION OF BROMIDE IS VERY SLOW. BIOLOGIC HALF-LIFE OF BROMIDE IS ABOUT 12 DAYS IN PT WITH NORMAL CHLORIDE INTAKE. MAX ACCUM DOES NOT OCCUR FOR APPROX 2 MO. LOW CHLORIDE INTAKE FACILITATES ACCUM OF BROMIDE BY REDUCING ITS URINARY EXCRETION. /BROMIDES/
ALTHOUGH RENAL EXCRETION OF BROMIDE IS SIMILAR TO THAT OF CHLORIDE, TUBULAR REABSORPTION OF BROMIDE IS MORE EFFICIENT THAN THAT OF CHLORIDE & THUS KIDNEYS EXCRETE CHLORIDE PREFERENTIALLY TO BROMIDE. ... SMALL AMT OF BROMIDE ARE EXCRETED IN SWEAT & FECES. /BROMIDES/
BROMIDE IN CONCN OF 0.25-1 MEQ/LITER HAS BEEN FOUND IN MILK OF NURSING MOTHERS WHO WERE RECEIVING 5 G OF SODIUM BROMIDE DAILY.
