Guanidine hydrochloride

Guanfacine Hydrochloride is a medication primarily used in the treatment of attention deficit hyperactivity disorder (ADHD) and high blood pressure. It is a type of drug known as a selective alpha-2A adrenergic receptor agonist.

Pharmacology

Guanfacine hydrochloride works by stimulating receptors in the brain that help to lower blood pressure. It does this by reducing the amount of norepinephrine available to stimulate the heart and other muscles. This results in a decrease in heart rate and blood pressure.

Medical Uses

Guanfacine hydrochloride is used in the treatment of high blood pressure and ADHD. In the case of ADHD, it is thought to help by affecting the part of the brain that controls attention and impulsivity. Guanfacine is not a stimulant, and is therefore often used in patients who cannot take stimulant medications due to health reasons or personal preference.

Side Effects

Common side effects of guanfacine hydrochloride include drowsiness, dry mouth, and constipation. In some cases, it can also cause low blood pressure, slow heart rate, and fainting. It is important for patients to discuss these potential side effects with their healthcare provider before starting treatment.

Dosage

The dosage of guanfacine hydrochloride will vary depending on the individual and the condition being treated. It is typically taken once a day, at the same time each day. The medication can be taken with or without food.
