Definisi Nyeri
Nyeri adalah pengalaman sensorik dan emosional yang tidak menyenangkan akibat kerusakan jaringan, baik aktual maupun potensial, atau yang digambarkan dalam bentuk kerusakan tersebut

Nyeri Inflamasi
• Nyeri akibat kerusakan jaringan atau proses inflamasi
• Dapat bersifat spontan atau dibangunkan
• Berguna untuk mempercepat penyembuhan

Nyeri Neuropatik
Nyeri yang disebabkan oleh lesi atau disfungsi pada sistem saraf
Meliala, 2004
“Berbuatlah dan cintailah tanpa memperhitungkan kebahagiaanmu sendiri,dan engkau akan berbahagia sepanjang waktu”
![Page 13: Management Of Different Types Of Pain · Management Of Different Types Of Pain. KRT Lucas Meliala. Guru Besar Luar Biasa. Bagian Ilmu Penyakit Saraf. Fakultas Kedokteran Universi](https://reader036.fdocuments.in/reader036/viewer/2022082213/5adaf7ad7f8b9a52528d94ff/html5/thumbnails/13.jpg)
WHAT IS NEUROPATHIC PAIN?
• Pain initiated or caused by a primary lesion or dysfunction in the peripheral or central nervous system
• Pain often described as shooting, electric shock-like, burning – commonly associated with tingling or numbness
• The painful region may not necessarily be the same as the site of injury. Pain occurs in the neurological territory of the affected structure (nerve, root, spinal cord, brain)
• Almost always a chronic condition (e.g. postherpetic neuralgia, poststroke pain)
• Responds poorly to conventional analgesics

Pengobatan Nyeri Neuropatik Saat ini
• Ditujukan untuk mengurangi kepekaan neuron di sistema nervorum perifer dan sentral dengan memodulasi aktivitas saluran ion (GBP, PGB, CBZ)
• Meningkatkan mekanisme inhibisi endogen (TCA, Duloxetine, opioid, Tramadol) dan hasilnya belum memuaskan
• Mengapa?????

EFNS guidelines for the treatment ofpainful polyneuropathy
• Drugs with established efficacy include PREGABALIN, gabapentin, TCAs, SNRIs,, strong opioids and tramadol
EFNS: European Federation of Neurological Societies
First line therapy PREGABALIN/gabapentin or TCAs/SNRIs (evidence level A)
Second line therapy Opioids and lamotrigine (evidence level B)
Lack of orweak efficacy
SSRIs, capsaicin, mexiletine, oxcarbazepine and topiramate (evidence level A)
Low strength evidence or safety concerns Carbamazepine and valproate
Recommendations:

Multidisciplinary approach to management
Initial symptom of pain, fatigue, etc• Disordered sensory processing• Neuroendocrine disturbances
Pharmacological therapies to improve symptoms
Functional consequences of symptoms• Distress• Decreased activity• Isolation• Poor sleep• Increased appetite• Maladaptive illness behaviors

Nonpharmacological therapiesto address dysfunction
• Strike a balance between pharmacological and non-pharmacological approaches

METHYCOBAL’S EFFECT ON ECTOPIC FIRING OF DORSAL ROOT GANGLION (DOG MODEL)
Atsuta et.al Methycobal Forum 1993; 101-103
Methycobal was added to the CSF solution
(to make a concentration of 50 μg.ml) bathing
the dorsal root ganglia During anoxia-induced
ectopic firing. The firing was suppressed
and the frequency (spike/sec.) dropped
significantly after the additionof Methycobal

Metilkobalamin: Kesimpulan • Metilkobalamin adalah bentuk aktif Vit B12, siap
digunakan tubuh dalam reaksi metilasi homosistein membentuk metionin
• Reaksi metilasi berperan pada pembentukan DNA, protein yang penting untuk saraf, pembentukan mielin dan transpor aksonal
• Metilkobalamin berperan pada regenerasi saraf yang mengalami kerusakan, misalnya pada, nyeri neuropatik, neuralgia nervus kranialis, peripheral nerve injury, vertigo dan tinitus dengan mengurangi ectopic discharge
![Page 46: Management Of Different Types Of Pain · Management Of Different Types Of Pain. KRT Lucas Meliala. Guru Besar Luar Biasa. Bagian Ilmu Penyakit Saraf. Fakultas Kedokteran Universi](https://reader036.fdocuments.in/reader036/viewer/2022082213/5adaf7ad7f8b9a52528d94ff/html5/thumbnails/46.jpg)
Kesimpulan • Metilkobalamin berperan pada penurunan kadar
homosistein mengurangi kerusakan saraf akibat terbentuknya reactive oxygen species
• Berperan pada proteksi neuron SSP akibat glutamate-induced neurotoxicity proteksi neuron pada stroke, cedera serebral, Alzheimer, Parkinson, Hipoglikemia dan Status epileptikus
• Secara umum sediaan oral maupun injeksi cukup aman dengan kejadian efek samping yang kecil

Eperisone HCl (Myonal ®)
• Golongan antispasmodik, banyak dipakai nuntuk efek muscle relaxant
• Insidensi sedasi kecil, dibanding obat lain yang segolongan– Mempermudah aplikasi klinis, untuk pasien
yang membutuhkan terapi tanpa mempengaruhi alertness
• Efek samping yang timbul biasanya jarang terjadi
