Ketamine troches [lozenges] by Dr Stephen Hyde :
This formulation is now available through most compounding pharmacists in Australia and has the advantage over the liquid solution that it is stable for six months and at the 50 and 100mg doses it is cheaper for the patient.
It is available in 20mg, 50mg and 100mg dosages
- 10x 20mg lozenges [200mg total] cost $38
- 10x 50mg lozenges [500mg total] cost $58
- 5x 100mg lozenges [500mg total] cost $58
It can be easily halved and quartered.
It takes a little longer to absorb than the oral liquid, it is best that patients have a warm drink just before hand to moisten the mouth and it is well absorbed buccally as well as sublingually – bigger doses can be divided and placed in both cheeks.
Absorption takes 8-10 minutes; any remnants can be swallowed and will still be active.
