Tetracaine 1% eye drop
Tetracaine is a local anaesthetic. In the PPR it can be found under:
‘Amino-alcohols esterified with benzoic acid, phenylacetic acid, phenylpropionic acid, cinnamic acid or the derivatives of these acids; their salts (except procaine when in a preparation containing any substance to which the Antibiotics Ordinance (Cap. 137) for the time being applies)’ (see Drug Office guide)
Under Schedules 1 and 3 as:
- Lignocaine; its salts in mixture with tetracaine or in mixture with the salts of tetracaine
- Tetracaine (being an amino alcohol esterified with a derivative of benzoic acid); its salts in mixture with lignocaine or in mixture with the salts of lignocaine
‘Amino-alcohols etc.’ is located, under P1.
In other words, tetracaine is only P1S1S3 if combined with lignocaine (Pliaglis cream).
The answer is P1
