Abstract

  Dolutegravir is a novel integrase stand transfer inhibitor active against human immunodeficiency virus. Dolutegravir is an integrase strand transfer inhibitor which preferentially blocks the strand transfer step of integration of the viral genome into the host cell's DNA mediated by the viral integrase enzyme. The authors have reviewed the analytical methods developed for the estimation of Dolutegravir in pharmaceutical dosage forms and in biological samples in the present paper.

Keywords: Dolutegravir; Integrase Strand Transfer Inhibitor; DNA

Introduction

  Dolutegravir is chemically (4R,12aS)-N-(2,4-difluorobenzyl)-7-hydroxy-4-methyl-6,8-dioxo-3 4,6, 8,12,12a-hexahydro-2H-pyrido[1',2':4,5]pyrazino[2,1-b][1,3]oxazine-9-carboxamide (C20H18F2N3NaO5). Dolutegravir is an integrase strand transfer inhibitor [1]. Dolutegravir sodium is a white to light yellow powder and is slightly soluble in water and methanol and is rapidly absorbed after oral administration and it was approved by FDA. Dolutegravir is active against HIV type 1 and also has some in vitro activity against HIV type 2 [2].

Figure 1: Structure of Dolutegravir.

  Dolutegravir blocks the strand transfer step of the integration of the viral genome into the host cell and prevents HIV from replicating and lowers the amount of HIV in the blood. Dolutegravir will not cure or prevent HIV infection or AIDS, however, it helps keep HIV from reproducing and appears to slow down the destruction of the immune system.

  Dolutegravir is available as tablets with brand name Instgra (Labelled claim 50 mg) from Avalon Pharma Pvt Ltd (India). Dolutegravir is also available in combination with Rilpivirine (Juluca) (Labelled claim: Dolutegravir: 50 mg and Rilpivirine: 25 mg) as film coated tablets; Lamivudine (Dovato) (Labelled claim: Dolutegravir: 50 mg and Lamivudine: 300 mg); Lamivudine and Tenofovir Disoproxil Fumarate (Viropil) (Labelled claim: Dolutegravir: 50 mg, Lamivudine: 300 mg and Tenofovir Disoproxil Fumarate: 300 mg).

  The authors have summarised the analytical methods so far developed in the literature for the determination of Dolutegravir in the present review article. The methods include are spectrophotometry [4-7], HPLC [8,9], HPTLC [10] (Table 1) for the pharmaceutical formulations. Liquid chromatographic methods were also developed for the separation of optical isomers of Dolutegravir [11,12] and for the estimation of Dolutegravir in human plasma using HPLC [13], UPLC [14] and LC-MS/MS [15].

Conclusion

  The present review article helps the readers to do research in a new field apart from the presenting existing analytical techniques for the anti-viral drug Dolutegravir.
