Answer
In The USP is a lithium citrate syrup described. Per 5ml contains 8mEq which is equivalent to the amount of 300mg Li-carbonate. The Litium citrate can be prepared from Li-carbonate and citric acid in a ratio so that we obtain approximately dilithium citrate.
from the reaction of 2 mol Li-carbonate (MG = 73.9) with 2 mol citric acid anh. (MG = 192) We get 2 mol diLi citrate (MG = 203).
this equation allows to calculate how much citric acid anh. You have to add to your amount of Li-carbonate.
There is also 0.3% v/V ethanol present. Nothing is mentioned about the other ingredients.
Neurolithium are potable ampoules with Li-gluconate (1 or 2g in 5 or 10ml water) plus 50 or 100mg NaCl. This would correspond to 34.35 mg or 68.7 mg Li.
