Ciprofloxacin and Levaquin (Levofloxacin) are in the same drug class (fluroquinolones). It makes sense that you would be allergic to both. You probably are allergic to other drugs in the same class such as moxifloxacinI, Ofloxacin, etc.s a fluoroquinolone, it is in the same class of agents as ciprofloxacin, enoxacin, levofloxacin, lomefloxacin, norfloxacin, and ofloxacin. Nalidixic acid is also a quinolone drug.
STC is calculated by taking the Transmission Loss (TL) values tested at 16 standard frequencies over the range of 125 Hz to 4000 Hz and plotted on a graph. Your curve (what you actually measured) is compared to standard STC reference curves (see appendix).
In a right triangle, the cosecant of an angle is the length of the hypotenuse divided by the length of the opposite side. In a formula, it is abbreviated to just 'csc'.Of the six possible trigonometric functions, cosecant, cotangent, and secant, are rarely used.ngles greater than 90Â°. In a right triangle, the two variable angles are always less than 90Â° (See Interior angles of a triangle). But we can in fact find the cosecant of any angle, no matter how large, and also the cosecant of negative angles. For more on this see Functions of large and negative angles.
