Mechanism of Daruvir 600mg

Darunavir is expels an anti-retroviral effect by inhibiting the protease enzyme which is responsible for HIV viral proliferation, Dimerization and catalytic effect of HIV-1 protease also forbidden.

In virus infected cells, darunavir involved in inhibits the separation of HIV encoded Gag-pol polyproteins, thus the inhibition which forbids the production of mature infectious virus particle.

Darunavir has molecular flexibility, so it can easily adapts for changing shape of protease enzymes.


The co administration of Daruvir with 100mg of ritonavir as two times a day, the Tmax value reaches between 2.5 to 4 hours.

The mean bioavailability of both Daruvir & ritonavir is occurs by 37% & 82% respectively.

The effect of food, while taking Daruvir with ritonavir with food causes increases Cmax & AUC of darunavir compared to fasted state.

Combination of Daruvir with ritonavir must be taken with food.


Daruvir should be bind with human plasma protein nearly by 95%


The metabolism of Daruvir is undergoing by oxidation.

The metabolism is intensively occurred with the help of CYP enzymes, formerly by CYP3A.


Darunavir is highly eliminated via feces & urine at range of 41.2% & 7.7%.

The mean terminal half life period of Daruvir is almost 15 hours.

The creatinine clearance of both Daruvir alone or in combination, is 32.8L/hr & 5.9L/hr respectively.

When to take the Daruvir 600mg

Daruvir should be administered with food.

Pediatric age of 3 to less than 18 years:

In pediatric patients, Daruvir should not be used as single dosing for daily.

Dose recommendation should be based on weighing at least 10kg but less than 15 kg;

Greater or equal to 10kg to less tan 11kg: The prescribed dose is 200mg of Daruvir with 32mg of ritonavir

Greater or equal to 11kg to less than 12 kg: The prescribed dose is 220mg of Daruvir with 32mg of ritonavir

Greater or equal to 12kg to less than 13kg: The prescribed dose is 240mg of Daruvir with 40mg of ritonavir

Greater or equal to 13kg to less than 14kg: The prescribed dose is 260mg of Daruvir with 40mg of ritonavir

Greater or equal to 14kg to less than 15kg: The prescribed dose is 280mg of Daruvir with 48mg of ritonavir.

Dose recommendation for weighing at least 15kg;

In severe hepatic impairment patients, the use of Daruvir should not be allowed.

Daruvir 600mg caused side effects

Abdominal pain







Acute pancreatitis




Acute hepatitis

Diabetes mellitus



Abnormal dreams

Stevens Johnson syndrome


Elevation of AST/ALT

Increasing alkaline phosphatase



Elevation of blood glucose level

Elevation of pancreatic lipase & amylase

Redistribution of fat


Epidermal necrosis

Acute generalized exanthematous pustulosis

Drug- drug interaction

Daruvir with ritonavir combined with drugs metabolized by CYP3A & CYP2D6, causes elevation of plasma concentration of these drugs which leads to cause extended therapeutic effect.

Both Daruvir & ritonavir are metabolized by CYP3A, drug which promote the CYP3A effect leads to elevate the clearance of darunavir & ritonavir which concluded as diminishing the plasma concentration of darunavir & ritonavir.


Daruvir & ritonavir combine with drugs which inhibits the CYP3A may leads to cause depleting the clearance of darunavir & ritonavir results as elevation of concentration of darunavir & ritonavir.

Daruvir tablet should be combined with Didanosine, affect the exposure of Didanosine. To overcome the problem Didanosine should be administered one hour earlier or two hours after the dose of Daruvir.

Daruvir concomitant with indinavir, causes increasing the effect of concentration of both darunavir & indinavir.

Daruvir with Lopinavir & ritonavir combination leads to cause decreasing the effect of concentration of darunavir

Daruvir combined with anti-arrhythmia agents causes increasing concentration of anti-arrhythmia.

Daruvir with warfarin an anti-coagulant, causes decreasing concentration of warfarin

Daruvir with carbamazepine an anti-convulsants, causes increasing the concentration of carbamazepine; with phenytoin or Phenobarbital causes decreasing the concentration of these drugs.

Daruvir combined with any anti-depressant agents, may leads to cause increasing the effect of concentration of these drugs.

Daruvir combined with anti-infective, anti-fungal or anti-gout cause’s elevation of effect of concentration of these drugs.

Daruvir combined with beta blocker, benzodiazepines, or calcium channel blocker, causes increasing its concentration.

 Daruvir with dexamethasone causes decreasing the concentration of darunavir

Daruvir with lipid lowering agents, causes increasing the effect of concentration of these drugs.

Daruvir with immunosuppressant causes increasing the concentration of immuno suppressants.

Food drug interaction

Presence of food will leads to elevates the level of darunavir in the body.

Food will lead the absorption of darunavir.

Possible contraindications

Some drugs may contraindicate to darunavir ritonavir combination;

Alfuzosin, ergot derivatives, Cisapride, pimozide, Midazolam, st. Johns wort, lovastatin, simvastatin, rifampin, sildenafil

Hypersensitive reactions are produced due to patients are contraindicate to the component present in the Daruvir tablets.

Safety measures

For general consideration, Daruvir should be combined with ritonavir and should be taken with food for better anti-viral activity.

Liver toxicity:

Drug induced hepatitis should be occurs, to avoid this problem, patient should be monitored with hepatic function test.

Sulfa allergy:

Darunavir is a sulfonamide moiety, use with cautiously if patients are allergy to sulfonamide.

Drug interactions:

Some drug – drug interaction may causes severe life threatening conditions. Avoid the combinational therapy.

Diabetes mellitus:

Increasing blood glucose level during the Daruvir therapy is a major adverse effect.

Monitor the patient’s glucose level during the treatment periodically.

Redistribution of fat:

The major adverse risk of this condition is obesity. This may generally occurs in anti-retroviral treatments.

Immune reconstitution syndrome:

This may occurs in Daruvir therapy; to overcome the problem therapy should be discontinued.


In protease inhibitor therapies, there is a chance of getting increased bleeding condition leads to skin hematomas & hemarthrosis in patients suffered with hemophilia type A or B.

Pregnancy and lactation

Pregnancy category C

Darunavir should not be used in pregnancy & lactating period.

Liver impairment:

Mild to moderate: No dosage adjustment

Severe: not recommended


Based on creatinine clearance value, dosage management should be considered.

Storage and handling

Daruvir container should be stored at 25oC

Do not store the container in heat, moisture & light

Missed dose

If missed dose occurs, must consult with medical practitioner and follow the instructions.

Regular dosing schedule should be maintained.

Over dosage

In case of over dosage, there is no special anti-dote is present for treating the over dosage of darunavir.

Provide general supportive measures

Gastric lavage or emesis should be suggested to remove the unabsorbed content from the body.

Activated charcoal is also indicated to eliminate the unabsorbed content.

Hemodialysis is also not beneficial, because darunavir is highly bound to human plasma protein.
