Clinical monograph: mirogabalin
BNF-referencedMirogabalin is a novel drug that acts as a selective ligand for the alpha-2-delta subunit of voltage-gated calcium channels. It is primarily used for the treatment of neuropathic pain, which can arise from various conditions such as diabetic neuropathy, post-herpetic neuralgia, and fibromyalgia. Mirogabalin offers a different mechanism of action compared to traditional analgesics, targeting pain pathways at the level of the nervous system.
Indications
- Neuropathic pain
- Diabetic neuropathy
- Post-herpetic neuralgia
- Fibromyalgia
Dosage
Children: Refer to BNF for Children for specific dosing information.
Adults: Refer to BNF for specific dosing guidelines.
Mechanism of action
Mirogabalin binds to the alpha-2-delta subunit of voltage-gated calcium channels, inhibiting the influx of calcium ions into neurons. This action reduces the release of excitatory neurotransmitters, ultimately decreasing the transmission of pain signals. By modulating the excitability of neurons, it helps in alleviating neuropathic pain.
Pharmacodynamics
Mirogabalin exhibits analgesic properties by modulating neurotransmitter release in the central nervous system. Its selective binding to the alpha-2-delta subunit enhances its efficacy in treating neuropathic pain while potentially reducing side effects associated with non-selective agents. The onset of action may vary, but users typically report pain relief within a few weeks of starting therapy.
Pharmacokinetics
Mirogabalin is absorbed following oral administration, with peak plasma concentrations usually attained within a few hours. Its bioavailability is influenced by factors such as food intake, which may alter absorption rates. The drug undergoes minimal metabolism, primarily excreted unchanged in urine. The half-life allows for once or twice-daily dosing to maintain therapeutic levels.
Adverse effects
- Dizziness
- Somnolence
- Dry mouth
- Constipation
- Peripheral edema
Precautions
- Caution in patients with a history of substance abuse
- Monitor for signs of misuse or abuse
- Consider dose adjustments in renal impairment
Pregnancy
There is limited data on the use of mirogabalin in pregnancy. It should only be used if the potential benefit justifies the potential risk to the fetus.
Breast-feeding
It is not known whether mirogabalin is excreted in human milk. Caution should be exercised when administering to nursing mothers.
Storage
Store at room temperature, away from moisture and heat. Keep out of reach of children.
