Claim 2
Dependent Claim
37 words
Process as in claim 2 in which said composition is a flowable droplet-forming suspension containing impalpable finely divided solid chloramphenicol and prednisolone in a liquid which is a uniform mixture of tetracaine, squalane and a hydrocarbon base.
Claim 3
Dependent Claim
