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 | J05AE | Protease inhibitors | |
| 5 | J05AE03 | Ritonavir |
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.

| Ritonavir |
Ritonavir is an orally active peptidomimetic inhibitor of the HIV-1 and HIV-2 aspartyl proteases. Inhibition of HIV protease renders the enzyme incapable of processing the gag-pol polyprotein precursor which leads to the production of HIV particles with immature morphology that are unable to initiate new rounds of infection. Ritonavir has selective affinity for the HIV protease and has little inhibitory activity against human aspartyl proteases. Pharmacokinetic enhancement by ritonavir is based on ritonavir’s activity as a potent inhibitor of CYP3A-mediated metabolism. |
