Resumo

A acne vulgar é uma condição inflamatória crônica que atinge cerca de 85% dos jovens, sendo a forma leve-moderada a forma mais prevalente. No campo farmacológico, os medicamentos tópicos são as alternativas mais utilizadas para o tratamento da acne, com a finalidade de reduzir os números de lesões. O objetivo do presente estudo foi avaliar qual classe de medicamento tópico apresenta maior eficácia: a convencional (clindamicina, eritromicina, retinoides e peróxido de benzoíla) ou a conservadora (probióticos, prebióticos, ácido salicílico, acido azeláico ou hidratantes com ceramidas). Para isso, fora realizada uma busca sistemática nas bases de dados PubMed, Embase e Web of Science, conforme a estratégia PRISMA. Foram localizados 20.597 registros, dos quais 27 ensaios clínicos randomizados foram totalmente elegíveis, com uma amostra geral de 6.202 pacientes. Os resultados demonstraram que as intervenções convencionais possuem ação mais rápida e potente, com reduções de lesões totais superiores a 70%. O uso de tazaroteno associado à clindamicina também se destacou, com 71% de redução em apenas 28 dias. A classe conservadora, especialmente o ácido salicílico supramolecular e dermocosméticos multialvos, exibiu eficácia comparável aos padrões tradicionais (redução média de ~54%), porém com tolerabilidade local significativamente superior. Probióticos e prebióticos mostraram-se eficazes na melhora global (50%), embora com resposta clínica mais lenta. Conclui-se que a classe convencional é mais eficaz na redução numérica imediata de lesões, enquanto a classe conservadora apresenta-se como uma alternativa viável e estratégica por equilibrar eficácia clínica com menor perfil de eventos adversos, favorecendo a adesão ao tratamento.
