Antimicrobial Efficacy of Some Products with Propolis Hydroalcoholic Extract 30% and Antiviral Synthesis
Abstract
The aim:
The purpose of this
study is to verify and prove antimicrobial efficacy of two topical
pharmaceutical finished products, a gel and a cream, with propolis hydro
alcoholic extract 30% 1 and an antiviral synthesis used as active
pharmaceuticals ingredients.
These
products are intended especially in the treatment of herpes or any of a group
of viral diseases caused by herpes viruses, affecting the skin (often with
blisters).
Methods
and Materials: The
study of antimicrobial efficacy was performed in accordance with the provisions
of the European Pharmacopoeia, 9th edition, version in force, method described
in Chapter 5.1.3. Efficacy of antimicrobial preservation and acceptance
criteria for preparations for cutaneous use2 and the specialty
literature.
The sample
under study was forcedly contaminated with suspensions (105/mL) of Staphylococcus
aureus, Pseudomonas aeruginosa, Candida albicans and Aspergillus
brasiliensis and the times studied were 0, 2, 7, 14, 21, 28 days.
Results:
Acceptance criteria
for antimicrobial efficacy are presented as a logarithmic reduction in the
number of viable microorganisms, calculate the ratio between the number of UFC/
mL from baseline (T0) and the number of UFC/ mL determined for each
test time and have been fully met.
