What Drugs Can Cause Pupil Dilation?
Pupil dilation is the enlargement of the black circle in the middle of the eye, which is caused by the muscles in the iris, the coloured part of the eye. Drugs that can cause pupil dilation are known as mydriatics, and they can be prescribed by a doctor or obtained illegally.
The most commonly prescribed mydriatic drugs are sympathomimetics, which are drugs that mimic the effects of the sympathetic nervous system on the body. These drugs can increase the heart rate, raise blood pressure, and cause pupil dilation. Sympathomimetics can be used to treat a number of medical conditions, such as glaucoma, iritis, and some eye infections.
Some recreational drugs can also cause pupil dilation. These include amphetamines, cocaine, ecstasy, and marijuana. They work by increasing the release of neurotransmitters, such as dopamine and serotonin, which can cause pupil dilation. These drugs can be very dangerous and should be avoided.
