Basic principles of pharmacotherapy of diseases of the visual organs

“…After administration under the conjunctiva, the highest concentration of the drug was noted after 3 hours, it disappears after 12 hours. With the disease, the barrier function weakens and the antibiotic penetrates the eye in greater quantities, nevertheless, the drug does not stay in the cornea and chamber moisture for a long time (maximum 60 minutes), but is eliminated after 2-3 hours [20]. The rapid removal of the drug from the chamber moisture is associated with its constant current and exchange [21][22][23].…”

“…When using prolonged-acting drugs due to the slow but constant release of the drug from the enriched form with a single injection, you can get a constant concentration of the active drug in the tissues for a long time. Currently, polymer-based substances, in particular, viscoelastic, are used to increase the viscosity (prolongation) of medicinal substances [20,27,28]. Modern methods of pharmacocorrection of the permeability of the blood-aqueous barrier are few and difficult to apply in practice.…”
