《Ophthalmic drug delivery》
▲Introduction/characteristics
Ophthalmic drugs are made by using various dispersion technology and sterile processing. The development of stable ophthalmic drugs requires to adjust the osmotic pressure, antimicrobiality of drugs, the number of particles, and the packing container selection.
1.Eye drops
2.Eye microemulsion
《Injectable drug delivery》
▲Introduction/characteristics
Development of the long-acting intramuscular injection by applying the technologies of drug particulate coating and emulsification or using target injection with liposomes. Meanwhile, the development of long-acting injections also uses the uniform particle sized biodegradable microsphere technology to increase the convenience use of the injectable drugs.
1.Long-acting injection
2.Long-circulating liposomes
《Drug property tests of liquid formulation》
▲Introduction/characteristics
Common tests of liquid formulated drugs, e.g. eye drops, injections or infusions.
1.Tests of particulate numbers: Fit the criteria of particulate matters in accordance with the Pharmacopoeia.
2.Osmotic pressure measurement: Osmotic pressure plays an extremely important factor of liquid transportation bio-processes in solute diffusion or bio-membrane permeability. Therefore, upon preparation of the injections, ophthalmic liquids, and drug formulations, the osmotic pressure must be noted.
