Problems solved by technology

Although the oral dosage form dissolves in gastric acid and is easy to absorb, it is widely distributed after absorption, and the blood concentration fluctuates greatly, which will bring many adverse reactions such as nausea, vomiting, abdominal pain, headache, etc., and occasionally liver damage and allergic reactions

Although ointment and other external dosage forms can reduce adverse reactions and expand the scope of clinical reference, they have the disadvantages of unsatisfactory transdermal effect, poor stability, and low bioavailability. They need to use azone, DMF, DMSO and other skin penetration to promote enhances transdermal absorption
