Antiarrhythmics representative of these categories include: Class IA— quinidine, procainamide, ajmaline, disopyramide, propafenone; Class IB—lidocaine, mexiletine, tocainide, as well as phenytoin; Class IC—flecainide. Note: With respect to classification, ?-blockers have been assigned to Class II, and the Ca2+-channel blockers verapamil and diltiazem to Class IV.
However, simultaneous administration would result in precipitation of nonabsorbable calcium fluoride in the intestines. With sodium monofluorophosphate this problem is circumvented. The new bone formed may have increased resistance to compressive, but not torsional, strain and paradoxically bone fragility may increase.

 

Follicular maturation and ovulation, as well as the associated production of female gonadal hormones, are controlled by the hypophyseal gonadotropins FSH (follicle-stimulating hormone) and LH (luteinizing hormone). In the first half of the menstrual cycle, FSH promotes growth and maturation of ovarian follicles that respond with accelerating synthesis of estradiol.
If the blood level exceeds the set-point, ACTH output is decreased and, thus, also the cortisol production. In this way cortisol level is maintained within the required range. The regulatory centers respond to synthetic glucocorticoids as they do to cortisol. Administration of exogenous cortisol or any other glucocorticoid reduces the amount of endogenous cortisol needed to maintain homeostasis.
