Triple antibiotic cationic ointment

Abstract

The present disclosure generally relates to petrolatum-based compositions for suspension of active ingredients and methods for forming stable suspensions of active ingredients in petrolatum, and more specifically to compositions of triple antibiotic cationic ointments. In particular, the present disclosure relates to a method for suspension of antibiotics and biocides in petrolatum at room temperature and a petrolatum-based composition having a stable suspension of active ingredients including antibiotics and biocides.

AI Technical Summary

Benefits of technology

The patent describes a method for creating a stable suspension of antibiotics and other active ingredients in petrolatum. This composition is useful for creating a triple antibiotic cationic ointment that can provide more effective coverage and prevent resistance to antibiotics. The process involves mixing antibiotic powder into a petrolatum base and adding nanodroplets of a liquid cationic biocide, resulting in a stable suspension of active ingredients. The composition can also be used for a biocide suspension ointment by adding the biocide in nanodroplets to a petrolatum base. These stable suspensions can provide more effective treatment for various skin conditions.

Problems solved by technology

A problem that is often encountered is the separation of the oil and aqueous phases over time, either by coalescing of the dispersed phase, or in some cases, by the combination of dispersed phase portions in a process of flocculation (formation of solid materials within the dispersion / suspension / emulsion that results in separation of the phases, with one in solid or semi-solid form.

Petrolatum is known to have advantageous protective properties when applied to the skin, however, its hydrophobic nature presents challenges with formulating active ingredients.

Petrolatum was also believed to be incapable of delivering active ingredients because the active ingredients would be trapped within the petrolatum and therefore would be unable to reach the desired delivery site.

Combination antibiotic therapy is frequently used to treat severe Gram-negative infections but is controversial and debatable.

However, excessive use of combinations should be avoided because it might be associated with increased risk for toxicity, superinfections, selection of resistant strains, and higher costs.

Antibiotics increase selective pressure in bacterial populations, causing vulnerable bacteria to die; this increases the percentage of resistant bacteria, which continue growing.
