Ritonavir Chemical Properties,Uses,Production

Chemical Properties

White or almost white powder.


Protease inhibitor; antiviral (HIV).


A selective HIV protease inhibitor


ChEBI: An L-valine derivative that is an antiretroviral drug from the protease inhibitor class used to treat HIV infection and AIDS, it is often used as a fixed-dose combination with another protease inhibitor, lopinavir. Also used in combination with dasabuvir sodium hydrate, ombitasvir and paritaprevir (under the trade name Viekira Pak) for treatment of chronic hepatitis C virus genotype 1 infection as well as cirrhosis of the liver.

brand name

Norvir (Abbott).


Ritonivir is an HIV protease inhibitor (EC50 = 25 nM) that also inhibits CYP3A4, the primary cytochrome P450 isoform that metabolizes protease inhibitors. Through CYP3A4 inhibition, low doses of ritonivir can reduce the metabolism of concomitantly administered protease inhibitiors, enhancing their bioavailability and efficacy.[Cayman Chemical]

Antimicrobial activity

Ritonavir is active against HIV-1 and, to a lesser extent, HIV-2.

Acquired resistance

At antiretroviral doses resistance is associated with the presence of specific amino acid substitutions in the HIV protease at positions 82 and 84. Concern about the risk for selection of ritonavir resistance when used at a subtherapeutic ‘booster’ dose has so far not been borne out by clinical experience.

Pharmaceutical Applications

A synthetic chemical available for oral use as soft capsules and a liquid formulation. It is now almost exclusively used as a pharmacokinetic enhancer to ‘boost’ the pharmacokinetic properties of HIV protease inhibitors in the treatment of HIV-1 infection in patients over 1 month in age.


Oral absorption: Not known/available
Cmax 600 mg twice daily: c. 11.2 mg/L
Cmin 600 mg twice daily: c. 3.7 mg/L
Plasma half-life: c. 3–5 h
Volume of distribution: c. 0.3–0.6 L/kg
Plasma protein binding: c. 97%
Absorption and distribution
Fasting and high-fat meals had no appreciable effect on oral absorption. It penetrates poorly into the CNS. The semen:plasma ratio is <0.04. It is distributed into breast milk.
Metabolism and excretion
Four oxidized metabolites have been identified, the major of which retains antiretroviral activity. Around 11% of the dose is excreted in urine, 4% as unchanged drug. The remainder is found in feces. Metabolites are eliminated primarily via the feces.
No dose adjustment is recommended in mild to moderate hepatic impairment. It should not be given to patients with severe hepatic impairment, nor should it be given as a pharmacokinetic enhancer to patients with decompensated liver disease.

Clinical Use

Treatment of HIV infection in adults and children >1 month old (in combination with other antiretroviral agents)

Side effects

Full (antiretroviral) doses are associated with nausea, vomiting, diarrhea and fatigue in >20% of subjects. The degree to which ritonavir at low dose is associated with specific adverse events is uncertain. In HIV-negative healthy volunteers given ‘booster’ doses of 100 mg every 12 h, the concentration of total cholesterol, low-density cholesterol and triglycerides all increased, and the concentration of high-density cholesterol concentration fell.
