Histamine H2 receptor antagonist are used in the clinical treatment of peptic ulcer. In vitro metaphase analysis and micronucleus assay were used to test the effect of Famotidine & Ranitidine on 60Cobalt gamma-ray induced clastogenic effects. Heparinised whole blood was obtained from 6 healthy volunteers and was gamma irradiated with 3Gy. Lymphocyte cultures were initiated and aqueous solution of Famotidine (150µg/ml) & Ranitidine (500µg/ml) was added at 0h and 24h. Cultures were harvested & processed at 48h & 72h for chromosome aberrations and micronucleus analysis respectively. At 0h & 24h after 3Gy gamma irradiation, cultures treated with Famotidine & Ranitidine independently showed significant decrease (p < 0.0001) in the frequency of chromosome aberration. At 0h & 24h Famotidine induced 60.91% & 56.42% inhibition in dicentrics & 59.39% & 56.21% inhibition was observed in total aberrations where as Ranitidine induce 52.11% & 43.54% inhibition in dicentrics and 53.06% & 46.66% inhibition in total aberrations at 0h & 24h. Significant decrease in the frequency of micronuclei was observed with Famotidine treatment after 3Gy of gamma irradiation, which induced inhibition of 48.83% (p < 0.0001) at 0hr & 5.02% (p < 0.016) at 24h. However, Ranitidine induced significant decrease (p < 0.0001) in frequency of micronuclei of 28.85% at 0h where as a decrease in frequency was observed of 2.88% at 24h although not significant when compared with 3Gy gamma irradiation alone. In conclusion radio protective effects of Histamine H2 receptor antagonists Famotidine and Ranitidine was observed on exposure togamma-ray.
