| | Indinavir Usage And Synthesis |
| Description | Crixivan was launched in Australia, Switzerland, the UK and the US
as an orally-bioavailable HIV-1 protease inhibitor. The compound can be prepared by
coupling an optically active piperazine derivative with an epoxide derivative (now
commercially available). The synthesis of the proteins, reverse transcriptase,
integrase, structural proteins and a protease, required by the virus to complete its
lifecycle, can be interupted if the protease enzyme is not capable of cleaving a proform
polypeptide chain into these components. lndinavir inhibits this process and is
more potent than the first approved protease inhibitor saquinavir. This effect was
noted by the increase in CD4+ cells and a decrease in HIV RNA levels. Since
indinavir is metabolized by the CYP3A4 isozyme, care must be taken with patients
with hepatic insufficiency and to sex-related differences in the level of this enzyme.
Other than nephrolithiasis (5%), indinavir is relatively safe and well tolerated. | | Originator | Merck (USA) | | Uses | Indinavir is a member of the novel hydroxyaminopentane amide class of HIV-1 protease inhibitors. Indinavir is used as an antiviral. It is a COVID19-related research product. | | Indications | Indinavir (Crixivan) is a potent inhibitor of HIV reverse
transcriptase. It produces the side effects common
to all protease inhibitors and also may produce
nephrolithiasis, urolithiasis, and possibly renal insufficiency
or renal failure. This problem occurs more frequently
in children (approximately 30%) than adults
(approximately 10%) and can be minimized by drinking
at least 1.5 L of water daily. Additional side effects include
asymptomatic hyperbilirubinemia, alopecia, ingrown
toenails, and paronychia. Hemolytic anemia
rarely occurs. Rifampin should not be given with indinavir. | | Definition | ChEBI: Indinavir is a N-(2-hydroxyethyl)piperazine, a piperazinecarboxamide and a dicarboxylic acid diamide. It has a role as a HIV protease inhibitor. | | Brand name | Crixivan | | Acquired resistance | The major mutations in the protease enzyme associated with
loss of the antiretroviral activity occur at positions 46, 82 and
84. Generally, the level of resistance rises with the number of
point mutations. | | General Description | When administered with a high-fat diet, indinavir(Crixivan) achieves a maximum serum concentration of77% of the administered dose. The drug is 60% bound inthe plasma. It is extensively metabolized by CYP3A4, andseven metabolites have been identified. Oral bioavailabilityis good, with a tmax of 0.8±0.3 hour. The half-life ofelimination is 1.8 hour, and the elimination products aredetectable in feces and urine. Indinavir also causes dyslipidemia.The available dosage forms are capsules of 200 mg,333 mg, and 400 mg. | | Pharmaceutical Applications | A synthetic compound formulated as the sulfate for oral
administration. | | Pharmacokinetics | Oral absorption: c. 65%v
Cmax 800 mg thrice daily: c. 8.97 mg/L
Cmin 800 mg thrice daily: c. 0.15 mg/L
Plasma half-life: c. 2 h
Volume of distribution: c. 0.4–1.74 L/kg
Plasma protein binding: c. 60%
Absorption and distribution
It is rapidly absorbed and not significantly affected by intake with food. Distribution in the body has not been fully characterized. It penetrates well into the CNS. The semen:plasma ratio is 1.9. It is distributed into breast milk.
Metabolism and excretion
Seven major metabolites have been described, including a glucuronide conjugate and six oxidative metabolites. Around 83% of the dose is recovered in feces and 18% in urine, 10% as unchanged drug. The effect of renal impairment has not been studied. It should be used with caution in the presence of hepatic impairment, particularly if severe. | | Clinical Use | Treatment of adult HIV infection (in combination with other antiretroviral
drugs) | | Side effects | The principal side effect is nephrolithiasis, including flank pain
with or without hematuria. There is good evidence that indinavir
directly causes nephrolithiasis as a result of crystallization
in the urinary tract. Indirect hyperbilirubinemia occurs in
about 10% of patients associated with inhibition of bilirubinconjugating
activity occurring as a result of competitive inhibition
of uridine diphosphate (UDP)-glucuronosyltransferase.
Ritonavir-boosted indinavir is associated with a dyslipidemia
profile characteristic of those treated with other
protease
inhibitors boosted with a 200 mg dose of ritonavir
per day. Insulin resistance and hyperglycemia have also been
associated with ritonavir-boosted indinavir. | | Drug interactions | Potentially hazardous interactions with other drugs
