Guanidine is a small basic compound. Guanidine stimulates the neuromuscular junction presynaptically by inhibiting voltage-gated potassium (Kv) channels, leading to the enhanced release of acetylcholine in the synaptic cleft. This stimulatory effect of guanidine underlies its use in the therapy for the neuromuscular diseases. The hydrochloride salt of guanidine was approved by FDA for the reduction of the symptoms of muscle weakness and easy fatigability associated with the myasthenic syndrome of Eaton-Lambert.

Approved Use

Guanidine is indicated for the reduction of the symptoms of muscle weakness and easy fatigability associated with the myasthenic syndrome of Eaton-Lambert. It is not indicated for treating myasthenia gravis. The Eaton-Lambert syndrome is ordinarily differentiated from myasthenia gravis by the usual association of the syndrome with small cell carcinoma of the lung, but myography may be necessary to make the diagnosis.

Sample Use Guides

Initial dosage is usually between 10 and 15 mg/kg (5 to 7 mg/pound) of body weight per day in 3 or 4 divided doses. This dosage may be gradually increased to a total daily dosage of 35 mg/kg (16 mg/pound) of body weight per day or up to the development of side effects.
Route of Administration: Oral
In Vitro Use Guide
Mice spinal cord neurons were treated with guanidine at concentrations between 100 nM and 100 mM. At 100 mM induced a membrane depolarization of 10 to 25 mV and rapidly and reversibly reduced GABA responses: 23.9% decrease of GABA responses was obtained with 10 mM guanidine and complete inhibition was observed with 100 mM). It also significantly reduced Glycine response at 10 mM.
