The World Health Organization's ATC classification organizes medical drugs based on therapeutic properties, chemical composition, and anatomy. It helps make essential medicines readily available globally and is widely used in the pharmaceutical industry.
| Level | Code | Title | |
|---|---|---|---|
| 1 | J | Antiinfectives for systemic use | |
| 2 | J05 | Antivirals for systemic use | |
| 3 | J05A | Direct acting antivirals | |
| 4 | J05AF | Nucleoside and nucleotide reverse transcriptase inhibitors | |
| 5 | J05AF02 | Didanosine |
The DDD is the assumed average maintenance dose per day for a drug used for its main indication in adults. The DDD is a unit of measurement and does not necessarily reflect the recommended or Prescribed Daily Dose. Therapeutic doses for individual patients and patient groups will often differ from the DDD as they will be based on individual characteristics (such as age, weight, ethnic differences, type and severity of disease) and pharmacokinetic considerations.

| Didanosine |
Didanosine belongs to a class of medicines called nucleoside analogues or nucleoside reversetranscriptase inhibitors (NRTIs). Intracellularly, didanosine is converted by cellular enzymes to the active metabolite, dideoxyadenosine 5'-triphosphate. Dideoxyadenosine 5'-triphosphate inhibits the activity of HIV-1 reverse transcriptase both by competing with the natural substrate, deoxyadenosine 5'-triphosphate, and by its incorporation into viral DNA causing termination of viral DNA chain elongation. |
