An explanation of the Genetic Code: DNA is a two-stranded molecule. Each strand is a polynucleotide composed of A (adenosine), T (thymidine), C (cytidine), and G (guanosine) residues polymerized by dehydration synthesis in linear chains with specific sequences.
SIDE EFFECTS. Common adverse reactions to systemically administered epinephrine include anxiety, apprehensiveness, restlessness, tremor, weakness, dizziness, sweating, palpitations, pallor, nausea and vomiting, headache, and respiratory difficulties.
One animal study suggests that cardiac arrest duration is a significant predictor of epinephrine's efficacy, producing hemodynamic benefits if administered soon after the onset of pulselessness but depressing myocardial function if administered later (Angelos et al., 2008).
