Figure 7.55 shows a plot of over 2000 2%DOPC/dodecane Pe measurements (10-6 cm/s units), each representing at least three intra-plate replicates, vs. the estimated standard deviations, o(Pe). Over 200 different drug-like compounds were measured. The %CV (coefficient of variation 100 x a(Pe)/Pe) is about 10% near Pe 10 x 10 6 cm/s, and slightly increases for higher values of permeability, but rapidly increases for Pe< 0.1 x 10 6 cm/s, as shown in Table 7.21. These statistics accurately reflect the errors that should be expected in general. For some molecules, such as caffeine and metoprolol, %CV has been typically about 3-6%. 

Omeprazole can inhibit the metabolism of drugs metabolised mainly by the cytochrome P-450 enzyme subfamily 2C (diazepam, phenytoin), but not of those metabolished by subfamilies lA (caffeine, theophylline), 2D (metoprolol, propranolol), and 3A (ciclosporin, lidocaine (lignocaine), quinidine). Since relatively few drugs are metabolised mainly by 2C compared with 2D and 3A, the potential for omeprazole to interfere with the metabolism of other drugs appears to be limited, but the half lives of diazepam and phenytoin are prolonged as much as by cimetidine. 

As electroporation is still largely in the experimental stage and may possibly be never used clinically, many workers have employed model nontherapeutic molecules to demonstrate the feasibility of its use, such as sulforhodamine, calcein, and caffeine. However, more therapeutic and biotechnologically derived molecules have now been investigated for transdermal delivery, including, for example, fentanyl [22], metoprolol [21], timolol [36], flurbiprofen [37], cyclosporin [38], heparin [39], oligonucleotides [40], and genes [41].

As many as 40% of patients complain of headache, memory impairment, confusion, poor concentration, and impaired motor performance. A fine hand tremor may be evident in np to 50% of patients. Stress, concomitant nse of antidepressants or antipsychotics, caffeine, sympathomimetics, and impending toxicity may exacerbate the tremor. Strategies to rednce the tremor inclnde standard approaches or adding a /3-adrenergic antagonist (e.g., propranolol 20 to 120 mg/day, atenolol 50 mg/day, or metoprolol 20 to 80 mg/day).
