Alltera tablet which exhibits anti-retroviral property. Alltera tablet is a which contain combination of Lopinavir 200mg and Ritonavir 50mg Both peak active ingredients consist of anti-viral activity against human immunodeficiency virus (HIV) which is required for causing AIDS Alltera is preventing the progression of HIV virus from multiplication. Alltera tablet is used to reduce problem related to AIDS, it is not cure or prevent the disease. Alltera combination helps to postpone the symptoms caused by HIV/AIDS.
Lopinavir and Ritonavir
200mg & 50mg
Alltera is primarily indicated for;
HIV infection associated AIDS
Normally, Alltera is used as combination with other anti-retroviral medicines.
Alltera is used to suppress the progression of HIV virus in immune cells and increase T cell counts. The number of Lopinavir blockade associated substitutions affects the virologic action of Alltera
Mechanism of action
Alltera is an anti-viral medicine that has two prime compounds which are inhibitors of HIV protease and effective against retrovirus.
Retrovirus has capable of converting RNA into DNA with the help of reverse transcriptase enzyme.
Then the viral DNA incorporated into DNA of affected immune cells and then multiplied Anti-viral activity of Alltera is exhibited by Lopinavir; it is a virulent protease inhibitor which inhibits the separation of Gag-Pol polyprotein.
Gag-Pol polyprotein is most important protein in the augmentation of active virus. This viral protease enzyme breaks the Gag-Pol polyprotein at the last stage of multiplication, an active and grown virus released into infected immune cells. A Alltera tablet prohibits the proteases enzyme that leads to formation of premature, non-infectious viral particles.
After oral administration, ritonavir present in Alltera tablet inhibits the metabolism of Lopinavir; therefore, the plasma level of Lopinavir is elevated. The peak plasma concentration of the Lopinavir occurs only at 4 hours after administration The effect of food, there is no significant difference between fasted and fed condition. Alltera should be taken with or without food.
The drug Lopinavir is highly bound to the human plasma protein around 98-99%.
Lopinavir is undergoes oxidative metabolism, it is metabolized by CYP3A isoenzymes. Ritonavir is a potent CYP3A inhibitor, prohibits metabolism of Lopinavir and increased the plasma level of Lopinavir.
Alltera is highly excreted through urine and feces. Lopinavir is a potent protease inhibitor which is responsible for anti-viral activity. The terminal half-life period is approximately 2.33 hours in case of twice daily, 2.44 hours at once daily.

Alltera should not administered as a single dose, in case of combination with carbamazepine, Phenobarbital, or phenytoin.
Alltera should be combined with some other anti-viral medicines; Efavirenz Nevirapine Nelfinavir By combining with the above mentioned anti-viral medicines, the prescribed dose of Alltera is 500mg/125mg, it is taken as 200mg/50mg as two tablets & 100mg/25mg as one tablet at two times a day in concomitant with efavirenz, nevirapine, Nelfinavir
The dose of Alltera in children is recommended on the basis of; Body weight or Body surface area (BSA) Alltera is not given as single dose for pediatric patients who are under the age of <18 years
Alltera not combined with efavirenz, nevirapine, Nelfinavir
15kg to 25kg: The BSA should be ≥0.6 to <0.9, the prescribed dose of Alltera 100mg/25mg as two tablets two times a day
>25kg to 35kg: BSA- ≥0.9 to <1.4, the recommended dose of Alltera 100mg/25mg as three tablets two times a day
>35kg: BSA ≥1.4, the dose should be taken as Alltera 100mg/25mg tablets as four tablets or two Alltera 200mg/50mg tablets.
Alltera combined with efavirenz, nevirapine, Nelfinavir
15kg to 20kg: The BSA should be ≥0.6 to <0.8, the prescribed dose of Alltera 100mg/25mg as two tablets two times a day
>20kg to 30kg: BSA- ≥0.8 to <1.2, the recommended dose of Alltera 100mg/25mg as three tablets two times a day

Alltera precautions and warning
Drug interaction-CYP3A enzyme prohibition, causes increased plasma concentration of concurrent used drugs. Avoid the concomitant use. Toxicity occurs to neonates, potential risk may occur while using Alltera in neonates. Take alcohol & propylene glycol from all the drugs should be given to infants for reducing the toxicity associated to the components.
Elevation of triglyceride levels may leads to cause pancreatitis. Pancreatitis is the major risk factor during the Alltera treatment. Lipase and amylase value should be monitored periodically.
Due to elevation of AST, ALT & bilirubin, leads to cause liver injury this may concluds as liver damage or failure.
Caution should be taken
Pregnancy women, Breastfeeding, Hepatic impairment, Geriatric patients
