PYRIDOSTIGMINE HAS A SLOWER ONSET (13 MIN) THAN EDROPHONIUM (3 MIN) OR NEOSTIGMINE (6-8 MIN), BUT A LONGER DURATION OF ACTION THAN EITHER. FOR THIS REASON, IT HAS BEEN RECOMMENDED FOR PATIENTS WITH RENAL IMPAIRMENT.

Cholinesterase Inhibitors
Drugs that inhibit cholinesterases. The neurotransmitter ACETYLCHOLINE is rapidly hydrolyzed, and thereby inactivated, by cholinesterases. When cholinesterases are inhibited, the action of endogenously released acetylcholine at cholinergic synapses is potentiated. Cholinesterase inhibitors are widely used clinically for their potentiation of cholinergic inputs to the gastrointestinal tract and urinary bladder, the eye, and skeletal muscles; they are also used for their effects on the heart and the central nervous system. (See all compounds classified as Cholinesterase Inhibitors.)
ITS ONSET OF ACTION BY ORAL ROUTE IS ABOUT 320 MIN...ITS DURATION OF ACTION BY THE ORAL ROUTE IS USUALLY SOMEWHAT LONGER AND ABSORPTION IS LESS ERRATIC THAN NEOSTIGMINE, WHICH ARE ADVANTAGES.

Plasma concn of pyridostigmine was determined in 2 nursing mothers who were receiving oral doses of pyridostigmine bromide, 120-300 mg daily. The drug was not detectable in infant plasma and there were no signs of drug effects in the infant.

PYRIDOSTIGMINE AND ITS QUATERNARY ALCOHOL ARE...THE PREDOMINANT ENTITIES FOUND IN URINE AFTER ADMIN OF THIS DRUG TO MAN.

After admin of pyridostigmine bromide (200 nmol/kg, iv) to human subjects, the disposition half-life was 0.6-1.78 min and terminal half-life was 14.81-37.01 min. Clearance was 9.3-26.5 ml/min/kg which was greater than the presumptive value for glomerular filtration rate and the vol of distribution was 246.5-833.9 ml/kg.

...PHARMACOLOGICAL EFFECTS OF ANTICHOLINESTERASE AGENTS ARE DUE PRIMARILY TO PREVENTION OF HYDROLYSIS OF /ACH/ ACETYLCHOLINE BY ACHE /ACETYLCHOLINESTERASE/ @ SITES OF CHOLINERGIC TRANSMISSION. TRANSMITTER THUS ACCUMULATES, AND THE ACTION OF ACH /ACETYLCHOLINE/ THAT IS LIBERATED BY CHOLINERGIC IMPULSES OR THAT LEAKS FROM THE NERVE ENDING IS ENHANCED.

Following admin of pyridostigmine bromide to rats, erythrocyte acetylcholinesterase activity recovered only slowly due to the covalent nature of inhibition. The logarithm of the plasma concn of pyridostigmine bromide was linearly related to the increase in tibialis twitch tension due to facilitation of neuromuscular transmission.

Of 12 analogs of pyridostigmine prepared by reacting 2-substituted 3-pyridinols with the desired carbamoyl chloride 2-iodo-3-(dimethylcarbamoyloxy)pyridine methiodide was the most active inhibitor of acetylcholinesterase and butyrylcholinesterase. The progressive inhibition curves for AChE and BuChE are compared and related to ionic attraction and steric requirements of the inhibitors.
