Scientists from the Federal University of Paraíba (UFPB) created an adhesive capable of curing, in 24 hours, the lesion caused by the herpes simplex virus. The very low-cost dressing, moldable to the size of the lesion, and which requires constant replacement, works through the controlled release of the drug Acyclovir in the region of the skin or mucosa affected by this category of the infectious agent.
How is it developed
Developed from a mixture of bioabsorbable and biodegradable synthetic polymers, the regenerative adhesive has a small dimension and high surface area, facilitating the addition of pharmacological agents, mainly Acyclovir, and aesthetic comfort.
Both the size and shape and the concentration of drug available are easily adaptable to the needs of a patient, unlike the current treatment through the use of Acyclovir tablets or ointment.
Kaline Ferreira, one of the inventors of the patent, explains that the characteristics of the adhesive can be modified as the proportion of polymers that make up its structure is varied. It is also possible to change the release of Acyclovir by modifying the structural dimensions of the dressing by controlling the polymer concentrations used and the production process parameters.
She points out that, even though it can be sold in any pharmacy, the Ministry of Health reinforces that any antiviral drug needs a prescription.
How the herpes sore patch can be made available
The regenerative adhesive was developed between 2015 and 2017. The patent was filed in June 2018, with the Brazilian Patent Office (BPTO). The dressing development process will be published soon. The articles are undergoing peer review in international journals.
The creators of the patent intend to talk to pharmaceutical companies to evaluate the cost-benefit for large-scale production of the adhesive.
