Drug Name Celebrex

The adrenal cortex (AC) produces the glucocorticoid cortisol (hydrocortisone) and the mineralocorticoid aldosterone. Both steroid hormones are vitally important in adaptation responses to stress situations, such as disease, trauma, or surgery. Cortisol secretion is stimulated by hypophyseal ACTH, aldosterone secretion by angiotensin II in particular.
Sulfonamides structurally resemble p-aminobenzoic acid (PABA), a precursor in bacterial DHF synthesis. As false substrates, sulfonamides competitively inhibit utilization of PABA, hence DHF synthesis. Because most bacteria cannot take up exogenous folate, they are depleted of DHF. Sulfonamides thus possess bacteriostatic activity against a broad spectrum of pathogens.

 

This steroid forms an integral constituent of cytoplasmic membranes of fungal cells, analogous to cholesterol in animal plasma membranes. Fungi exposed to imidazole derivatives stop growing (fungistatic effect) or die (fungicidal effect). The spectrum of affected fungi is very broad.
By stimulating ?1-receptors, hence activation of adenylatcyclase (Ad-cyclase) and cAMP production, catecholamines augment all heart functions, including systolic force (positive inotropism), velocity of shortening (p. clinotropism), sinoatrial rate (p. chronotropism), conduction velocity (p. dromotropism), and excitability (p. bathmotropism).
