Development of a Single Dose Formulation from Psidium guajava (guava) leaves

Principal Investigator Dr. Tannaz  Birdi

Collaborator Dr. R. Vishwakarma, IIIM, Jammu and Dr. Geetha Krishnan, Medanta Hospital, Gurgaon.

Project Team Dr. Pooja Gupta, Ms. Poonam Daswani

Funder Preliminary work undertaken through Corpus Grant to FMR from Jamsetji Tata Trust (2011-2014)

An industrial partner needs to be identified for undertaking the manufacture and marketing of PGL formulation and taking the work forward.

Duration 3 years

Preliminary work done

  • The data on seasonal and regional variation has been generated. The extract at 1% shows minimal variation.
  • This shows that irrespective of the season or the location from which guava may be collected, its leaves will exhibit anti-diarrhoeal activity. Hence the SDF can be developed from guava leaves collected anytime from any location.
  • The toxicity studies have been carried out at IIIM, Jammu. The extract was found to be non-toxic at 2000mg/kg body weight p.oand has been classified as category 5 as per Globally Harmonized System of Classification of Chemicals (GHS) of Organization for Economic Co-operation and Development (OECD).
  • In the absence of a formulation, the Integrated Medicine Department of Medanta hospital under Dr. Geetha Krishnan’s supervision has treated 10 cases of diarrhoea with a freshly prepared aqueous PGL extract. The results have been encouraging

Plan of study

  • Stability of extract
  • Designing of a formulation
  • Shelf life and toxicity of formulation
  • Efficacy of formulation in an animal model
  • IND application
  • Proof of concept- Open efficacy trial
