Drug Name Ortho Tri-Cyclen

This reaction can be observed after the application of ?-sympathomimetics (naphazoline, tetrahydrozoline, xylometazoline) to the nasal mucosa. Initially, vasoconstriction reduces mucosal blood flow and, hence, capillary pressure. Fluid exuded into the interstitial space is drained through the veins, thus shrinking the nasal mucosa.
In emergencies, such as hyperglycemic coma, it can be given intravenously (mostly by infusion because i. v. injections have too brief an action; plasma t1/2 ~ 9 min). With the usual subcutaneous application, the effect is evident within 15 to 20 min, reaches a peak after approx. 3 h, and lasts for approx. 6 h. Lispro insulin has a faster onset and slightly shorter duration of action.

 

Nonetheless, these changes are significant because the patient experiences relief from the torment of psychotic personality changes; care of the patient is made easier and return to a familiar community environment is accelerated.
Nicotinic acid and its derivatives (pyridylcarbinol, xanthinol nicotinate, acipimox) activate endothelial lipoprotein lipase and thereby lower triglyceride levels. At the start of therapy, a prostaglandin-mediated vasodilation occurs (flushing and hypotension) that can be prevented by low doses of acetylsalicylic acid.
