Does Fentanyl patch increase blood pressure?
Fentanyl, like most opiates, actually reduces your blood pressure. Being both a vasodilator (opens the blood vessels) and a depressant, opiates relax the body, and with the blood vessels open wider, blood flows more easily. This is also why you feel cold when the dosage gets low - the blood vessels are constricting.Of course if you have serious issues in your arteries or veins like plaque, etc., or have high blood pressure to begin with, it might not help, but in most cases it won't affect it unless the patient isn't tolerant or is allergic. That's rarely the case since Fentanyl isn't prescribed for those who aren't already using a lower dosage of opiate by oral means.
Is minoxidil a steriod?
No. Minoxidil is a direct acting peripheral vasodilator that reduces elevated systolic and diastolic blood pressure by decreasing peripheral vascular resistance. This means it lowers your blood pressure by increasing the circumference of your blood vessels and relaxing the smooth muscles of your blood vessels. When the blood vessels are "wider" and "pump" less hard, blood can flow with less pressure through the vessels.

What causes the pupil to constrict and dilate?
The pupils of your eyes become smaller due to light. When it is dark, the pupil opens wider to allow more light in so that it is easier for us to see. When it is bright, the pupil contracts in order to keep too much light from damaging the sensitive parts in the back of the eye. It has also been noted that drugs, such as hallucinogens and opiates can cause a change in the size of the pupil, usually making them open wider despite the level of light.
