This disruption to the electrochemical gradient is in part rectified by the passive secretion of positively charged sodium ions in to the lumen and water follows by osmosis.Plecanatide is also known to have an anti-nociceptive effect in animal models, however the exact mechanism of action is not yet fully elucidated. It has been suggested that this may be in part to the anti-inflammatory action of guanylate cyclase-C by its inhibition of pro-inflammatory cytokines, or through the inhibition of associated sensory neurons. Pharmacokinetics and metabolism
As plecanatide acts on receptors present on the apical side of endothelial cells lining the gastrointestinal tract it is able to impart its effect without ever entering circulation. As with most orally ingested peptides, plecanatide is degraded by intestinal enzymes, and so very little of the active drug enters systemic circulation. Minimal amounts of the drug are expected to be transported in to the body, and concentrations of plecanatide and its metabolites are undetectable in plasma following the recommended dosage of 3 mg. It has also been shown that dosages up to 48.6 mg produced no detectable concentration of plecanatide in human plasma at any time point after ingestion. References

Potential treatment interventions include splinting, therapeutic exercise, manual stretching, soft tissue and joint mobilization, postural training and bracing, neuromuscular electrical stimulation, constraint-induced movement therapy, activity and environmental modification, and gait training.A patient with dystonia may have significant challenges in activities of daily living (ADL), an area especially suited for treatment by occupational therapy (OT). An occupational therapist (OT) may perform needed upper extremity splinting, provide movement inhibitory techniques, train fine motor coordination, provide an assistive device, or teach alternative methods of activity performance to achieve a patients goals for bathing, dressing, toileting, and other valued activities.Recent research has investigated further into the role of physiotherapy in the treatment of dystonia. A recent study showed that reducing psychological stress, in conjunction with exercise, is beneficial for reducing truncal dystonia in patients with Parkinson’s disease. Another study emphasized progressive relaxation, isometric muscle endurance, dynamic strength, coordination, balance, and body perception, seeing significant improvements to patients quality of life after 4 weeks.Since the root of the problem is neurological, doctors have explored sensorimotor retraining activities to enable the brain to "rewire" itself and eliminate dystonic movements. The work of several doctors such as Nancy Byl and Joaquin Farias has shown that sensorimotor retraining activities and proprioceptive stimulation can induce neuroplasticity, making it possible for patients to recover substantial function that was lost due to Cervical Dystonia, hand dystonia, blepharospasm, oromandibular dystonia, dysphonia and musicians dystonia.Some focal dystonias have been proven treatable through movement retraining in the Taubman approach, particularly in the case of musicians.
