Description of Synthivan

Trade name: Synthivan Active ingredients: Atazanavir sulfate and Ritonavir Strength: Atazanavir sulfate 300mg and Ritonavir 100mg Mfg: cipla Category: Anti retroviral agents Synthivan Product description: Synthivan an anti-retroviral agent which contains active ingredients like Atazanavir sulfate and Ritonavir Both ingredients having anti-retroviral activity and it is protease inhibitors. Protease enzyme which is essential for cell maturation and multiplication Synthivan is a cipla product. It is not a curable but it reduce the progression of the infection

Pharmacology of Synthivan

Mechanism of action: Atazanavir sulfate, it is an azapeptide HIV-1 protease inhibitor, active against human immunodeficiency virus type I Generally protease enzyme is essential for proteolytic cleavage of viral polyprotein into functional proteins present in infectious HIV-1. This atazanavir bounds to the active site of the protease enzyme and prohibits its activity. This prohibition leads to prevent the separation of viral polyprotein; it concludes formation of immature cells and turns to non-infectious cells Ritonavir, it is a peptidomimetic HIV protease inhibitor Low dose of Ritonavir acts as pharmacokinetic booster of concomitantly used other anti-retroviral drug Atazanavir, it increase the plasma concentration of Atazanavir concurrently Pharmacokinetic: Absorption: Atazanavir is quickly absorbed with the Tmax of relatively 2.5 hours. If Synthivan is taken with food, leads to increase bioavailability of atazanavir and depletes its pharmacokinetic variability Oral bioavailability is around 60-68% Distribution: Atazanavir is highly bound to human serum protein nearly 86%. It binds to alpha-1-acid glycoprotein and albumin (89% and 86%) respectively Metabolism: The major biotransformation pathways like; Monooxygenation Dioxygenation Synthivan is highly metabolized in liver It is metabolized by CYP3A Elimination: The route of elimination is not known clearly The terminal half life of Synthivan in healthy persons is around 7 hours Hepatic impairment patients 12.1 hours

Indication of Synthivan

Synthivan tablet is a fixed dose regimen that involved in the treatment of HIV type I infected associated with AIDS. Synthivan is used only for decreasing the progression of HIV virus maturation and multiplication It is not cure or prevents the infectious condition

Dose & Dosage's of Synthivan

Synthivan tablet should be taken with food The recommended dose of Synthivan based on the medical history of the patients Synthivan is a prescription medicine; it is administered under the guidance of medical practitioner The recommended dose of Synthivan for adult patients: One tablet should be taken orally with meals as a single dose. Combination therapy: One tablet should be taking once daily with food, if Synthivan is combined with any medicines like; Tenofovir H2 receptor antagonist: The dose of H2 receptor antagonist like famotidine should not exceed 40mg two times a day. Synthivan tablet is administered concurrently with or 10 hours after the dose of famotidine. Proton pump inhibitor: Omeprazole, a proton pump inhibitor it should not exceed to 20mg. Omeprazole should be administered in 12 hours prior to the dose of Synthivan tablet Dose recommendation for therapy experienced patients: If H2 receptor antagonist co administered with Synthivan tablet, dose of famotidine should not exceed to 20mg twice daily. Synthivan should be taken with food if co administered with famotidine Synthivan should not be taken, if both tenofovir and H2 receptor antagonist has been taken together. Proton pump inhibitor drugs should not taken, if treatment experienced patient taking Synthivan tablets Efavirenz should not concomitant with Synthivan tablet; it leads to decrease the Synthivan exposure. Missed dose: Synthivan tablet is a prescription medicine; if patient fail to administer the dose, advice them to take within a time. Otherwise the missed dose should be skipped and follow the regular drug schedule.

Side Effects of Synthivan

The serious effects that caused by Atazanavir; Cardiac conduction abnormalities Rashes Hyperbilirubinaemia Chronic kidney disease Nephrolithiasis and cholelithiasis Nausea Jaundice/scleral icterus Diarrhea, edema Fever Depression Myalgia Hepatic function abnormalities Alopecia Arthralgia Pancreatitis QTc prolongation

Contraindication of Synthivan

Patients are highly contraindicated to the components that present in the Synthivan tablet While Synthivan co administered with drugs which are highly dependent on CYP3A leads to increasing plasma concentration of interacting drugs causes life threatening conditions Synthivan concomitant with strongly CYP3A inducers may causes loss of efficacy of atazanavir List of medicines that are contraindicated; Alfuzosin, rifampicin, Irinotecan, Lurasidone, Pimozide, Midazolam, st. johns wort, lovastatin, simvastatin, sildenafil, indinavir, nevirapine,

Drug Interaction of Synthivan

Atazanavir is a CYP3A4 substrate, drug which induce CYP3A4 may leads to decrease the plasma concentration and therapeutic effects of the atazanavir. Co administration of Didanosine with Synthivan tablets leads to decrease the atazanavir exposure Tenofovir with Synthivan: decrease the AUC and Cmin of atazanavir and increase the plasma concentration of tenofovir Atazanavir combined with efavirenz: decrease the exposure of atazanavir Some list of medicines; Saquinavir, antacids, amiodarone, lidocaine, quinidine, carbamazepine, phenytoin, phenobarbitol etc

Precaution of Synthivan

Some drug interaction may have chance to get; Severe skin reactions, Hyperbilirubinaemia, hepatoxicity, chronic kidney disease If patient suggested for concomitant therapy, care should be taken to reduce life threatening conditions Co administration of ritonavir with some other drugs like sedative, hypnotics, anti-arrhythmia may leads to severe life threatening adverse reactions.
