ABSTRACT
In the present work, oral dispersible tablets of Enalapril maleate were prepared using three different superdisintegrants and a co-processed superdisintegrant consisting of crospovidone and sodium starch glycolate in the ratio 1:1. Oral dispersible tablets of Enalapril maleate were prepared by employing direct compression technique using the above superdisintegrants, and evaluated for precompression as well as post-compression parameters, such as determination of weight variation, thickness, hardness, friability, wetting time, disintegration time, drug content, water absorption ratio, in vitro dispersion time, and in vitro drug release study. Formulation F-VII. F-VIII and F-IX were subjected to stability Studies as per ICH guidelines at temperatures and humidity of 25±5ºC/60±5%RH; 30±5ºC/65±5%RH and 40±5ºC/75±5%RH. Tablets didn’t reveal any appreciable changes in respect to hardness, disintegration time, drug content and dissolution profiles. From the results, it could be concluded that the formulation(F-VII) made with coprocessed super disintegrant (1:1) at a concentration of 5% w/w revealing a disintegrating time of 13.2 sec, and 97.84 % cumulative drug release emerged as the best formulation.
ABSTRACT
Background: Cancer data from Rajasthan are limited. Only two studies, one from Western Rajasthan, and the other from Eastern Rajasthan have been published by Sharma et al. in 1992 and 1996. Aims: To put the cancer profile from this region in proper perspective, we conducted the present study on the patterns of various malignancies in Jaipur region, i.e., Eastern Rajasthan. Setting and Design and Material and Methods: The study spans over one and half decade (1990-2004) and is based on a retrospective six-year sample analysis of approximately 200,000 histopathological and cytological reports for the years 1990, 1991, 1996, 1999, 2001 and 2004. Results: A total of 21,868 cancers were recorded in the six sample years. There were 59.11% (12,926) males and 40.89% (8942) females, with the male to female ratio being 1.45:1. Organ wise, lung (8.45%), prostate (7.12%), brain (6.04%), urinary bladder (5.31%), esophagus (4.67%) and tongue (4.60%) are most common sites involved in males with regard to frequency, whereas breast (20.44%), cervix (14.99%), ovary (4.35%), brain (3.80%), esophagus (3.67%), uterus (3.01%) and rectum (2.80%) are common sites for malignancies in females. Conclusions: Significant findings were a higher frequency of cancers of the prostate, urinary bladder, and brain in males along with gall bladder cancers in females. Our figures have been compared with the national data.
