  • Publication number: 20220203042
    Abstract: A safety housing based implant/medicament injecting system. System includes a needle assembly prefilled implant/medicament for injection and an injecting needle/cannula, a housing for accommodating the needle assembly under usual bias inside said housing, a plunger means having a plunger rod configured for stage wise forward motion including an initial injecting plunger forward motion with the needle assembly within the housing to first engage the needle assembly with the housing and subsequent continuing injecting plunger forward motion independent of the needle assembly for injecting of the implant/medicament, and post injecting return of the needle assembly secured inside said housing blocking any subsequent use thereof.

  • Patent number: 7138387
    Abstract: Sterile pharmaceutical stable autoclaved clear aqueous compositions of propofol (2,6-Diisopropyl phenol) suitable for parenteral administration are described. The compositions essentially consist of a complex of propofol with 2-hydroxypropyl-?-cyclodextrin in a weight ratio of 1:30–1:60. This complex of propofol with 2-hydroxypropyl-?-cyclodextrin produces a clear aqueous composition that is stable to autoclaving. The composition is effective as an anaesthetic agent. The process of making these synergistic compositions has been described.

  • Patent number: 7053061
    Abstract: Parenteral compositions of oil-coated-Amphotericin B in structured-emulsion form, having LD50 of at least 400 mg/kg in mice and process for making the same have been described. The process essentially requires dispersing Amphotericin B in oily vehicle and dispersing emulsifier in the aqueous phase. The process of present invention is simple, cost effective and gives a stable product suitable for parenteral administration. Amphotericin B emulsion compositions prepared by the process of the present invention may be administered to human beings and animals for the treatment of fungal infections, with substantially equivalent or greater efficacy and low drug toxicity as compared to the conventional composition containing Amphotericin B and sodium desoxycholate.
