“… 64 , 65 Several studies provide evidence for simple passive diffusion as the primary mechanism of drug permeation. 66 , 67 , 68 , 69 , 70 Simple passive diffusion involves the law of diffusion in which a molecule moves from an area of higher concentration to that of lower concentration and while this may be the most efficient mechanism since it does not require an energy input, many complications can arise due to varying properties of drug molecules, such as size and charge. 65 Carrier‐mediated diffusion is also another common mechanism of drug absorption and utilizes a transmembrane carrier to transport a drug molecule across the epithelia.…”

“…A elevação da pressão arterial é grave e pode lesar os órgãos do indivíduo, levando-o até mesmo a óbito. Sendo assim é necessário que o tratamento tenha efeito em minutos ou no máximo em até uma hora após o início da crise hipertensiva (CHETTY et al, 2001). A descoberta da eficácia e rapidez do tratamento para Hipertensão Arterial Sistêmica (HAS) utilizando o Captopril pela via sublingual, deu-se porque foi possível verificar que a concentração plasmática do medicamento no organismo atingiu seu nível terapêutico em tempo inferior a via convencional, que teoricamente seria a via recomendada para a formulação na qual o medicamento é fabricado, porque o princípio ativo não realiza metabolização de primeira passagem para depois demonstrar seus efeitos terapêuticos no organismo (AL-FURAIH et al, 1991).…”
