Mechanism of action:

The exact mechanism of anticonvulsant action of bromide is incompletely understood.
The action appears to involve chloride ion channels which are an important part of the inhibitory neuronal network of the CNS.

Their function is modulated by GABA. Increased chloride ion flow, as a result of activation of GABA receptors by barbiturates or benzodiazepines, results in increased neuronal inhibition and increases the threshold for seizures.

Bromide appears to cross neuronal chloride channels more readily than chloride because it has a smaller hydrated diameter. By competing with chloride ions, bromide hyperpolarizes postsynaptic neuronal membranes and facilitates the action of inhibitory neurotransmitters.

Barbiturates may act synergistically with bromide to raise the seizure threshold by enhancing chloride conductance via GABA-ergic activity.

Dosage :

Dogs:

To achieve a serum level of approximately 1 mg/mL, give 120 mg/kg PO daily for 5 days then reduce 30 mg/kg PO once daily. To achieve a serum level of approximately 1.5 mg/mL, give 160 mg/kg PO for 5 days and then reduce to 40 mg/kg PO once daily thereafter.

For seizures: 400 – 600 mg/kg/day divided and given with food. May be given over 24 hours or more gradually over 5 days. Then go to initial maintenance dose: 20 – 30 mg/kg PO once daily.

For idiopathic epilepsy: 100 mg/kg (q6h) for the first 24 hours, or 100 mg/kg (q24h) for 4 days. Maintenance dose: 35 – 40 mg/kg PO once daily (q24h). Serum KBr concentrations at 8 weeks, 12 weeks and every 6 months thereafter

Cats:

As third choice (after phenobarbital and diazepam) therapy of refractory seizures: 10 – 20 mg/kg/day PO. Follow same guideline as dogs.
As second line therapy for epilepsy: 30 mg/kg PO once daily.
