Heme is central to functions of many biologically important enzymes (hemoproteins). It is an assembly of four porphyrin rings joined through methylene bridges with a central Fe (II). Heme is present in all cells, and its synthesis and degradation balance its amount in the cell. The deregulations of heme networks and incorporation in hemoproteins lead to pathogenic state. This article addresses the detailed structure, biosynthesis, degradation, and transportation associated afflictions to heme. The article is followed by its roles in various diseased conditions where it is produced mainly as the cause of increased hemolysis. It manifests the symptoms in diseases as it is a pro-oxidant, pro-inflammatory and pro-hemolytic agent. We have also discussed the genetic defects that tampered with the biosynthesis, degradation, and transportation of heme. In addition, a brief about the largest hemoprotein group of enzymes- Cytochrome P450 (CYP450) has been discussed with its roles in drug metabolism.

Successful drug therapy depends on the interaction between drug-drug and drug-diet. Drug interactions are a vital reason for causing adverse drug reactions and modify one drug effect by another drug and these kinds of interactions can increase or decrease the effectiveness of the drug. Polypharmacy could be a major risk for Drug-Drug and Drug-food interactions. Food Consumption can alter the effect of drugs by interfering either with their pharmacokinetics or pharmacodynamics processes. Anti-ulcer drugs are used to treat different types of ulcer and that may interact with another drug showing undesirable effects. GIT medications interfere with another type of medication either with at the pharmacokinetic and pharmacodynamic level. The main objective of this article is to review data regarding common Drug-drug & Drug-food interactions related to GIT medications. Data was collected from Google Scholar, PubMed, and Scopus databases, and they were reviewed for publication on drug-drug & drug-food interactions related to GIT medications. This data is very helpful for pharmacists while reviewing and analyzing prescribed medication, especially in geriatrics prescriptions.

As the number of people taking multiple medications increases, differing approaches to address drug-drug interactions and adverse drug reactions have been debated—but not solved—despite excellent criteria to stop the use of potentially inappropriate medications.

Purpose. The primary objective of this study was to investigate the incidence of drug-drug interactions (DDIs) related to adverse drug reactions (ADRs) in elderly outpatients who attended public primary healthcare units in a southeastern region of Brazil. The secondary objective was to investigate the possible predictors of DDI-related ADRs. Methods. A prospective cohort study was conducted between November 1, 2010, and November 31, 2011, in the primary public healthcare system in the Ourinhos micro-region in Brazil. Patients who were at least 60 years old, with at least one potential DDI, were eligible for inclusion in the study. Eligible patients were assessed by clinical pharmacists for DDI-related ADRs for 4 months. The causality of DDI-related ADRs was assessed independently by four clinicians using three decisional algorithms. The incidence of DDI-related ADRs during the study period was calculated. Logistic regression analysis was used to study DDI-related ADR predictors. Results. A total of 433 patients completed the study. The incidence of DDI-related ADRs was 6.5%. A multivariate analysis indicated that the adjusted odds ratios (ORs) rose from 0.91 (95% confidence interval [CI] = 0.75-1.12, p = 0.06) in patients aged 65-69 years to 4.40 (95% CI = 3.00-6.12, p < 0.01) in patients aged 80 years or older. Patients who presented two to three diagnosed diseases presented lower adjusted ORs (OR = 0.93 [95% CI = 0.68-1.18, p = 0.08]) than patients who presented six or more diseases (OR = 1.12 [95% CI = 1.02-2.01, p < 0.01]). Elderly patients who took five or more drugs had a significantly higher risk of DDI-related ADRs (OR = 2.72 [95% CI = 1.92-3.12, p < 0.01]) than patients who took three to four drugs (OR = 0.93 [95% CI = 0.74-1.11, p = 0.06]). No significant difference was found with regard to sex (OR = 1.08 [95% CI 0.48-2.02, p = 0.44]). Conclusion. The incidence of DDI-related ADRs in elderly outpatients was significant, and most of the events presented important clinical consequences. Because clinicians still have difficulty managing this problem, highlighting the factors that increase the risk of DDI-related ADRs is essential. Polypharmacy was found to be a significant predictor of DDI-related ADRs in our sample. This article is open to POST-PUBLICATION REVIEW.
