Naivex tablet is used to treat HIV type I infection. Naivex tablet preferred for HIV infection, it is non-curable and non-preventable. But it can able to suppress the growth of HIV virus and leads to elevate immune cells T cells Dolutegravir, it is an IInd generation HIV Integrase strand transfer inhibitor Naivex is recent anti-retroviral drug, used in HIV infection associated to AIDS Naivex is recommended to combine with other medicines containing anti-retroviral properties.

Pharmacology of Naivex

Naivex (Dolutegravir), contains anti-viral property against HIV type I infection. Naivex is an Integrase inhibitor, which can able to prohibit HIV cell growth by interfering with Integrase binding to the active site and blockade of strands transfer step occurred. The viral DNA integration into host cells get stopped This transfer process is responsible for HIV cell multiplication cycle. This leads to inhibition of viral activity Pharmacokinetic: Absorption: In HIV infected adults patients, 50mg of Naivex tablets (Dolutegravir) is given orally; the peak plasma concentration of the drug occurs within 2 to 3 hours post-dose. The steady state is attains within 5 days The volume of distribution of Dolutegravir is 17.4 L Distribution: Naivex (Dolutegravir) is largely bound to the human plasma protein at the range of 98.9% of administered dose. Metabolism: Naivex tablet is metabolized by three pathways Glucuronidation by UGT1A1 Carbon oxidation by CYP3A4 Sequential oxidative defluorination and glutathione conjugation The major metabolite of Dolutegravir is occur in blood plasma, it is in ether glucoronide form and the chemical property of the metabolite is disrupt its efficiency to bind with metal ion so it is in inactive stage Elimination: The drug is in unchanged form should be excreted through feces 53%; urine 31% The terminal half life of Dolutegravir is 14 hours The clearance rate of Dolutegravir is 1.0L/hr

Indication of Naivex

Naivex (Dolutegravir) is mainly indicated for HIV type I infections, used with other anti-retroviral drugs to treat the infection affected in both adults and pediatric patients If patient those who are virologically suppressed, will take Rilpivirine; it is a complete regimen to treat HIV-1 infection in adults to replace the current anti-retroviral drugs.

Dose & Dosage's of Naivex

The recommended dosage of Naivex tablets for various conditions; Treatment naïve or treatment-experienced INSTI-naïve or virologically suppressed adults turns to Dolutegravir plus rilpivirine: The prescribed dose of Dolutegravir is 50mg once daily Treatment naïve or therapy-experienced naïve 50mg of Dolutegravir should be concomitant with certain UGT1A or CYP3A inducers as twice daily INSTI-experienced with certain INSTI-associated resistance substitutions or INSTI resistance: 50mg of Dolutegravir should be administered as twice daily Naivex should be taken with or without food Rilpivirine dose is 25mg once daily For pediatric: Depending upon the body surface area of the pediatric patients, the dosage of Naivex tablet should be calculated; 30kg to less than 40kg: 35mg of Dolutegravir should be recommended as a single dose (one 25mg + one 10mg) 40kg or greater: 50mg once daily If Naivex concomitant with UGT1A or CYP3A inducers, then increase the weight based dose of Dolutegravir to twice daily Naivex tablet should be administered 2 hours before or 6 hours after cation containing antacids or laxatives, sucralfate, oral supplements. Dolutegravir with calcium or iron supplements should be taken together with food Missed dose: If patient fail to take the dose, they must be administered within 4 hours of next dose. Otherwise the missed dose should be skipped and follow the regular dosing schedule.

Side Effects of Naivex

Hyperglycemia, increased serum ALT, insomnia, fatigue, headache, suicidal ideation, depression, suicidal tendencies, Pruritus, increased serum lipase, diarrhea, abdominal distress, abdominal pain, flatulence, neutropenia, leucopenia, Hyperbilirubinaemia, hepatitis, hypersensitivity reactions, increased creatinine phosphokinase, myositis, renal insufficiency, acute hepatic failure, increase serum creatinine, Myalgia, rashes,

Contraindication of Naivex

Naivex tablets are contraindicated in patients; Hypersensitivity reaction to Dolutegravir Co administration of Naivex with dofetilide, leads to increased the plasma concentration of dofetilide cause serious life threatening conditions

Drug Interaction of Naivex

Dolutegravir with metformin or dofetilide, the plasma concentration of these drugs are elevated Dolutegravir is metabolized by UGT1A1, drug that induce this enzymes may decrease the plasma concentration of Dolutegravir leads to reduce therapeutic effects of the drug Co administration of Naivex tablet with etravirine leads to decrease the plasma concentration of Naivex Avoid some drugs to concomitant with Dolutegravir like; Nevirapine, fosamprenavir/ritonavir, tipranavir/ritonavir, carbamazepine, Phenobarbital, phenytoin, antacids, rifampin, oral calcium or iron supplements

Precaution of Naivex

Caution with use; Hypersensitivity reaction Hepatotoxicity Immune reconstitution syndrome

Usage & Safety profile of Naivex Pregnancy & Lactation
