In-vitro Dissolution Profile and Other Physical Parameters Determination of Cimetidine Formulations | Chapter 7 | Pharmaceutical Science: New Insights and Developments Vol. 5

Peptic ulcers are a category of disorders that manifest as a rupture in the intestinal epithelium that becomes saturated in acid and pepsin. It is the most frequent digestive tract disorder, with a global prevalence of 80% in developing and 40% in industrialised countries. The study aimed to compare the effectiveness and bioavailability using the in vitro dissolution method and assess other physicochemical properties of different brands of cimetidine tablets. Cimetidine is a model biopharmaceutics classification system (BCS) class-III medicine that is N-(amino sulfonyl)-3-[2 - [(diamine methylene) amino]-4-thiazolyl] methyl] thio] propanimidamide. It is a strong Histamine-2 (H2) receptor antagonist used in the treatment of peptic ulcers.

 

Five (5) different brands of cimetidine tablets, labelled A–E, were purchased and used for the analysis. Physicochemical tests such as weight uniformity, hardness, disintegration, friability, and dissolution test were conducted following standard British pharmacopoeia procedures. Samples A-E conformed to the weight uniformity standard with a mean % weight deviation of 0.37 – 1.39 %, while E had 11.52% based on the batch used. Samples B and A had the highest mean kgf (10.5 and 9.7), while sample E had the lowest kgf (4.4), hence liable to mechanical damage. All the samples used for the analysis had below 1.0% friability. All the samples passed the disintegration test, with sample A having the longest disintegration time (4.44 minutes) and sample C having the shortest disintegration time (0.21 minutes). At 25.99 minutes, Sample A had the fastest disintegration rate.

 

The method used in the analysis is accurate, precise, and cost-effective. The analysis does not require pretreatment of the drug and can compete with other existing methods in the routine quality control analysis of cimetidine in pharmaceutical formulation.

Liver Damage due to the Interaction of Malathion with Cimetidine in Rat: Advanced Study | Chapter 6 | Technological Innovation in Pharmaceutical Research Vol. 5

 Cimetidine (C) and cimetidine with malathion (M + C) were employed in this chapter to analyze oxidative stress enzymes indicative of liver damage in rats exposed to malathion (M) in a subchronic form. Cimetidine, a histamine H2-receptor antagonist, has been shown to inhibit a variety of CYP450 isoforms. Malathion, an organophosphorus pesticide that is widely used, causes oxidative liver damage. Male Wistar rats weighing 200-250 g were investigated after being exposed to Malathion (0.15 mg/kg/day, 2 mg/kg/day, 15 mg/kg/day) and cimetidine (10 mg/kg/day) were given orally for three weeks. Malathion influences oxidative stress susceptibility and may modify antioxidant defense capacity directly or indirectly. This research will lead to new clinical diagnoses and treatments for pesticide-induced liver disease, as well as a focus on oxidative stress in organophosphate-exposed individuals and the development of intervention approaches.
