Common side effects of steroid use

Omeprazole acts as an inhibitor of CYP2C19. Omeprazole, given in doses of 40 mg daily for one week to 20 healthy subjects in cross-over study, increased Cmax and AUC of cilostazol by 18% and 26% respectively. C max and AUC of one of its active metabolites, 3,4-dihydro-cilostazol, which has 4-7 times the activity of cilostazol, were increased by 29% and 69% respectively. Co-administration of cilostazol with omeprazole is expected to increase concentrations of cilostazol and its above mentioned active metabolite. Therefore a dose reduction of cilostazol from 100 mg twice daily to 50 mg twice daily should be considered.

Scientists continue to work on better ways to design, conduct and evaluate non-randomized (., observational) studies to assess how well flu vaccines work. CDC has been working with researchers at universities and hospitals since the 2003-2004 flu season to estimate how well flu vaccine works through observational studies using laboratory-confirmed flu as the outcome. These studies currently use a very accurate and sensitive laboratory test known as RT-PCR (reverse transcription polymerase chain reaction) to confirm medically-attended flu virus infections as a specific outcome. CDC’s studies are conducted in five sites across the United States to gather more representative data. To assess how well the vaccine works across different age groups, CDC’s studies of flu vaccine effects have included all people aged 6 months and older recommended for an annual flu vaccination. Similar studies are being done in Australia, Canada and Europe. More recently, CDC has set up a second network the Hospitalized Adult Influenza Vaccine Effectiveness Network (HAIVEN) that looks at how well flu vaccine protects against flu-related hospitalization among adults aged 18 and older.

And, exacerbating these two age-related erosive events, some catabolites of tryptophan can lead to the formation of mutagenic nitrosamines or the activation of an immunosuppressive receptor (which is usually triggered by toxicants such as xenobiotics), promoting carcinogenesis (Mezrich, et al., 2010; Chung & Gadupudi, 2011).

The consumption of a supplement of tryptophan will likely nurture or augment these disastrous age-associated disease states, by raising injurious tryptophan derivatives (particularly in the presence of a vitamin B6 deficiency, an insufficiency of stomach acid, a magnesium deficit, and a vitamin B3 deficiency).

Furthermore, tryptophan side effects in regards to greater mortality were shown in animal experiments (., Catrina, et al., 2001) using melatonin, whereas the study authors cautioned:

“[...] melatonin had a deleterious effect on the survival rate raising the question whether it is correct to assume that the hormone shows lack of adverse reactions.” [emphasis added]

In regard to serotonin's involvement in the promotion of higher mortality, one of its anti-longevity effects is conceivably the reabsorption of phosphate (a pro-inflammatory chemical) by the kidneys since klotho, an anti-aging protein, facilitates the excretion of phosphate from the kidneys (Peat, Nov. 2012).

Since tryptophan, serotonin, and melatonin meddle with basic energy production in cells, and since metabolic efficiency and functionality decreases proportionally with aging (Fannin, et al., 1999; O'Toole, et al., 2010) due to various factors, it seems coherent in biological terms that these substances are less prevalent, thus less “essential” or needed, in older people, as a further decrease of an already suboptimal general metabolic working order will aggravate physiological function systematically, increase the risk for disease (as exemplified and foreshadowed with tryptophan side effects), promote the aging process, and explains the increased mortality related to the administration of these substances.

Several tryptophan side effects, such as tryptophan's carcinogenic activities, the deterioration of metabolic energy function, and the promotion of hypertension, can rather readily account for a greater death rate.

While atazanavir/ritonavir does reduce the lamotrigine plasma concentration, no adjustments to the recommended dose-escalation guidelines for LAMICTAL should be necessary solely based on the use of atazanavir/ritonavir. Dose escalation should follow the recommended guidelines for initiating adjunctive therapy with LAMICTAL based on concomitant AED or other concomitant medications (see Tables 1, 2, and 5). In patients already taking maintenance doses of LAMICTAL and not taking glucuronidation inducers, the dose of LAMICTAL may need to be increased if atazanavir/ritonavir is added, or decreased if atazanavir/ritonavir is discontinued [see CLINICAL PHARMACOLOGY ].
