Gastric acid is subsequently neutralized by bicarbonates in the duodenum order micardis 80mg amex, attaining a value of pH 5 generic 80 mg micardis overnight delivery. The cecum and the ascending colon are usually more acidic than the small intestine, by one-half to one pH unit, but a higher pH of 6–7 or above is reached more distally. Indeed, inhibition of presystemic metabolic processes is likely to be a factor in a 34% to 103% increase in the bioavailability of nifedipine observed in individuals consuming grapefruit juice. First-pass metabolism in the liver is another important issue for oral drug delivery. This loss of drug from the bloodstream on passage through the liver is termed the first-pass effect. In some cases, the first-pass effect may result in virtually complete elimination of the original drug. Although this is generally disadvantageous for drug delivery, first-pass metabolism can be beneficial for prodrugs, which rely on drug metabolism for activation. Drugs that structurally resemble nutrients such as polypeptides, nucleotides, or fatty acids may be especially susceptible to enzymatic degradation. For example, the proteolytic enzymes chymotrypsin and trypsin can degrade insulin and other peptide drugs. In the case of insulin, proteolysis was shown to be reduced by the coadmmistration of carbopol polymers at 1% and 4% (w/v%), which presumably shifted the intestinal pH away from the optimal pH for proteolytic degradation. Drugs such as erythromycin, penicillin, and omeprazole are unstable in acidic media, and will therefore degrade and provide lower effective doses depending on the gastric pH, drug solubility, and residence time of the dosage form in the stomach. Thus, hydrophobic substrate molecules that enter the membrane lipid bilayer from the lumen will be extracted directly back to the extracelluar medium by the P-glycoprotein, prior to reaching the cell cytoplasm. An alternative model proposes that substrate efflux through the pump (at low substrate concentration) occurs via a four-step mechanism. The drug substrate is bound to P-glycoprotein on the cytoplasmic side of the cell membrane. There is a high level of expression of P-gp in the epithelial cells of the small intestine. Compounds that have been found to be substrates exhibit a wide range of chemical structures. However, they tend to be lipophilic and, for some, cationic, such as anthracyclines, vinca alkaloids, cyclosporin, etoposide, and celiprolol. It has been shown that taxol, an anti-microtubule anticancer drug, was not absorbed after oral administration in pre-clinical trials. This can probably be attributed to P-gp, since the flux from the 140 basolateral to the apical side was 4–10 times greater than in the opposite direction. Thus, P-gp may play an important role in determining the oral bioavailability of certain drugs. Food may reduce the rate or extent of absorption by a number of mechanisms: • By slowing down gastric emptying rate, which is a particularly important effect for compounds unstable in gastric fluids and for dosage forms designed to release drug slowly. Enzymes present in these fluids may deactivate a drug moiety; similarly, increased acid secretion provoked by the presence of food may cause increased degradation of acid-labile compounds. The deleterious effects of food on drug absorption have prompted the use of dietary strategies in order to improve oral bioavailability. For example, the drug L-dopa, used in the treatment of Parkinson’s disease, is absorbed via a stereospecific, saturable active transport mechanism shared by large neutral amino acids such as phenylalanine and tyrosine. The breakdown products of dietary proteins can compete with L-dopa for this active transport mechanism, thereby reducing its oral bioavailability. Taking L-dopa at least 30 min before eating and controlling dietary protein has been shown to improve L-dopa treatment in Parkinson’s disease. A further example is the avoidance of milk 2 h prior to taking preparations containing tetracyclines, as these drugs chelate calcium ions in milk, forming a poorly absorbable complex. Interestingly, the presence of food may favor drug absorption in other situations. The positive effect of food on the absorption of this drug was also observed with Eudragit S100 nanoparticles. The administration of a 150 mg diclofenac hydrogel-based capsule dose within 30 min following a standardized breakfast was shown to minimally affect the bioavailability of dicolfenac relative to administration under fasted conditions. The insoluble fraction forms 141 a semi-impermeant layer, which, in conjunction with bicarbonates (secreted by gastric cells at the surface and in gastric pits), protects underlying cells from damage by gastric acid. Studies have shown that gastrointestinal mucus presents a physical barrier to the diffusion of small molecules such as urea, benzoic acid, antipyrine, l-phenylalanine and warfarin as well as to large protein molecules. Similarly, the passive absorption of testosterone was shown to be doubled upon ridding the intestinal epithelial cells of the overlying mucus layer. However, the situation regarding the effect of mucus on oral bioavailability is a complex one; for example, it has been shown that drug binding to the mucosal surface is essential to the absorption of barbituric acid derivatives from the rat small intestine. Gender Gastric acid secretion is greater in men than in women, whereas gastric emptying time is slower in women. Enzyme expression is also different between men and women; for example, sex-related cytochrome P-450 isozymes and glucuronidation enzymes are more abundant in men. However, in general, gender differences are small and insufficient to warrant a modification in dosage regiments.
