Tolperisone is a centrally acting muscle relaxant that has been used for the treatment of post-stroke spasticity and low back pain. Recently, the safety of tolperisone pharmaceutical products has been reassessed due to growing concerns over allergic adverse events. Reactive degradants of tolperisone may be responsible for these hypersensitivity reactions. By forming adducts with proteins, they may act as haptens that could evoke allergic reactions. The objective of this study was to examine the presence of these degradants in tolperisone pharmaceutical products and to assess their reactivity to elucidate their possible role in the pro-allergic effect of tolperisone. For this purpose, capillary electrophoresis UV detection (CE-UV) method was developed and validated for the quantification of degradants. A dual cyclodextrin system was applied to achieve the appropriate migration order enabling the analysis of 2-methyl-1-(4-methylphenyl)prop-2-en-1-one (MMP) and 1-(4-methylphenyl)propan-1-one (MMPO) in the presence of high concentrations of tolperisone. MMP was identified as the main degradant in forced degradation tests of the active pharmaceutical ingredient. Differences in MMP content of tolperisone products by different manufacturers have also been found, highlighting the role of formulation in their stability. High reactivity of MMP was demonstrated as rapid and almost complete adduct formation with cysteine was found. This degradant thus might be responsible for the allergic adverse effects of tolperisone even when it is present in trace amounts in tablets by readily reacting with proteins in vivo.

Tolperisone hydrochloride improves motor functions in Parkinson’s disease via MMP-9 inhibition and by downregulating p38 MAPK and ERK1/2 signaling cascade

Article

Author: Mostafa, Irona ; Bosu, Tory ; Esha, Nusrat Jahan Ikbal ; Chowdhury, Humayra Noor ; Sharmin, Ayesha ; Uddin, Kabir M ; Rahman, Mahbubur ; Hassan, Tazree ; Mallick, Anup ; Zaman, Bushra ; Islam, Mm Shanjid ; Chowdhury, Fowzia Afsana ; Hossain, Md Mainul ; Ahmed, Shamim

The mitogen-activated protein kinase (MAPK) signaling pathway, particularly the p38 MAPK and ERK1/2, has been implicated in the pathogenesis of Parkinson's disease (PD). Recent studies have shown that MAPK signaling pathway can influence the expression of matrix metalloproteinase 9 (MMP-9), known for its involvement in various physiological and pathological processes, including neurodegenerative diseases. This study explores the modulation of MMP-9 expression via the MAPK/ERK signaling cascade and its potential therapeutic implications in the context of PD-associated motor dysfunction. Here, tolperisone hydrochloride (TL), a muscle relaxant that blocks voltage-gated sodium and calcium channels, was used as a treatment to observe its effect on MAPK signaling and MMP-9 expression. Rotenone (RT) exposure in mice resulted in a significant reduction in substantia nigra and primary motor cortex neurons, which were further evidenced by impairments in motor function. When TL was administered, neuron count was restored (89.0 ± 4.78 vs 117.0 ± 4.46/mm²), and most of the motor dysfunction was alleviated. Mechanistically, TL reduced the protein expression of phospho-p38MAPK (1.06 fold vs 1.00 fold) and phospho-ERK1/2 (1.16 fold vs 1.02 fold), leading to the inhibition of MAPK signaling, as well as reduced MMP-9 concentrations (2.76 ± 0.10 vs 1.94 ± 0.10 ng/mL) in the process of rescuing RT-induced neuronal cell death and motor dysfunction. Computational analysis further revealed TL's potential inhibitory properties against MMP-9 along with N and L-type calcium channels. These findings shed light on TL's neuroprotective effects via MMP-9 inhibition and MAPK signaling downregulation, offering potential therapeutic avenues for PD-associated motor dysfunction.

Symptomatic Cavum Vergae Cyst in a Geriatric Patient: A Report of a Rare Case and Conservative Management Approach

Author: Petrov, Petar-Preslav ; Velev, Andrey ; Penchev, Plamen ; Velchev, Vladislav

Cavum vergae (CV) cysts constitute a small proportion of intracranial cysts, and although generally asymptomatic, there are occasional cases where they might exhibit clinical manifestations. We present a clinical case of a 79-year-old female patient who had a clinical manifestation of headache on the occipital side of the head with irradiation to the shoulder girdle as well as numbness, dizziness, visual impairment, sleep disturbances, and tingling in the hands for three months. Vertigo and rightward staggering had been experienced for two weeks. On physical examination, it was discovered that there was smoothed physiological lordosis, restricted and painful movements, and paravertebral muscle rigidity in the cervical region. The patient had bilaterally reduced biceps and triceps reflexes, painful Erb's points, and hypesthesia over the C5 and C6 dermatomes on the right side. The patient had decreased coordination and displayed staggered movement to the right. A CT scan discovered dilated subarachnoid spaces of the convexity and a CV cyst. The patient was prescribed conservative therapy consisting of etoricoxib oral at a dosage of 2 × 60 mg for seven days, tolperisone hydrochloride orally at a dosage of 2 × 150 mg for seven days, pregabalin 75 mg, one pill in the evening for seven days, ozoid (a gel containing ozone) for external application, and vinpocetine 2 × 10 mg orally for two months. Following the conservative treatment, the patient exhibited improvement in her symptoms and no longer had challenges carrying out her daily tasks. Furthermore, six months after the therapy, the patient did not experience any symptoms. Long-term follow-up will be conducted in cases of symptom recurrence or cyst enlargement.

Comparative Effectiveness of Meds for Acute Low Back Pain Unclear

MONDAY, March 27, 2023 -- For patients with acute low back pain , the comparative effectiveness and safety of analgesic medications is unclear, according to a systematic review and meta-analysis published online March 22 in The BMJ . Michael A. Wewege, from the University of New South Wales in Sydney, and colleagues conducted a systematic review and network meta-analysis to assess the comparative effectiveness and safety of analgesic medicines for acute nonspecific low back pain. Data were reviewed from 98 randomized controlled trials (15,134 participants), which included 69 medicines and combinations. The researchers observed low or very low confidence in evidence for reduced pain intensity after treatment with tolperisone, aceclofenac plus tizanidine, pregabalin (mean differences, −26.1, −26.1, and −24.7, respectively), and 14 other medicines versus placebo. There was low or very low confidence seen for no difference between the effects of several of these medications. There was moderate to very low confidence noted for increased adverse events with tramadol, acetaminophen plus sustained-release tramadol, baclofen, and acetaminophen plus tramadol compared with placebo (risk ratio, 2.6, 2.4, 2.3, and 2.1, respectively). There was moderate-to-low confidence for these medicines increasing the risk for adverse events compared with other medicines. For secondary outcomes and a secondary analysis of medicine classes, moderate-to-low confidence was also noted. "Despite nearly 60 years of research involving more than 15,000 patients, high quality evidence to guide clinical decisions on analgesic medicines for acute nonspecific low back pain remains limited," the authors write. The Sydney Pharmacy School receives funding from GlaxoSmithKline for a postgraduate scholarship supporting a research student supervised by one of the authors. Abstract/Full Text Posted March 2023
