Guanadrel Sulfate
- indication:Used to treat and control hypertension.
- pharmacologypharmacology:
- mechanism: Guanadrel is a postganglionic adrenergic blocking agent. Uptake of guanadrel and storage in sympathetic neurons occurs via the norepinephrine pump or transporter. Guanadrel slowly displaces norepinephrine from its storage in nerve endings and thereby blocks the release of norepinephrine normally produced by nerve stimulation. The reduction in neurotransmitter release in response to sympathetic nerve stimulation, as a result of catecholamine depletion, leads to reduced arteriolar vasoconstriction, especially the reflex increase in sympathetic tone that occurs with a change in position.
- toxicity: Side effects include dizziness, drowsiness, headache, constipation, diarrhea, gas pains, loss of appetite, fatigue, and nasal congestion.
- absorprion: Rapidly and readily absorbed from the gastrointestinal tract.
