Hepatic Impairment:

Mild: No dose adjustment needed.
Moderate: No dose adjustment needed.
Severe: No dose adjustment needed.

Pharmacology

πŸ”¬

Mechanism of Action

Pregabalin binds with high affinity to the alpha2-delta (Ξ±2-Ξ΄) subunit of voltage-gated calcium channels in the central nervous system. While the precise mechanism of action is unknown, binding to the Ξ±2-Ξ΄ subunit is thought to modulate the release of several excitatory neurotransmitters, including glutamate, norepinephrine, and substance P, thereby reducing neuronal excitability and pain signaling.
πŸ“Š

Pharmacokinetics

Absorption:

Bioavailability: Approximately 90%
Tmax: Approximately 3 hours (fasting) to 4 hours (with food) for Lyrica CR.
FoodEffect: Food delays Tmax by approximately 3 hours and reduces Cmax by approximately 25-30% for Lyrica CR, but does not significantly affect the extent of absorption (AUC).

Distribution:

Vd: Approximately 0.56 L/kg

⚠️

Precautions & Cautions

It is essential to inform all your healthcare providers, including doctors, nurses, pharmacists, and dentists, that you are taking this medication.

Before engaging in activities that require alertness or clear vision, such as driving, wait until you understand how this medication affects you.

If you experience changes in your seizures or if they worsen after starting this medication, consult your doctor promptly.

Do not abruptly stop taking this medication without first consulting your doctor, as this may increase your risk of side effects. If you need to discontinue this medication, your doctor will instruct you on how to gradually taper off the dosage.

While taking this medication, it is recommended that you avoid consuming alcohol.

Before using marijuana, other forms of cannabis, or prescription or over-the-counter medications that may impair your reactions, discuss the potential risks with your doctor.

A severe and potentially life-threatening reaction called angioedema has been associated with this medication. Symptoms may include swelling of the hands, face, lips, eyes, tongue, or throat, difficulty breathing, swallowing problems, or unusual hoarseness. If you experience any of these symptoms, seek immediate medical attention.

Severe respiratory problems have occurred in individuals taking this medication, particularly when combined with other medications like opioid pain relievers, or in those with pre-existing lung or breathing issues. The risk may be higher in individuals over 65 years old, and in some cases, these breathing problems have been fatal. If you have concerns, consult your doctor.

If you are 65 years or older, use this medication with caution, as you may be more susceptible to side effects.

Men who plan to father a child should discuss the potential risks with their doctor, as this medication has been shown to reduce fertility and cause sperm changes in male animals, and has also been associated with birth defects in the offspring of treated male animals. Although it is unclear if these effects occur in humans, it is crucial to weigh the benefits and risks.

If you are pregnant or plan to become pregnant, inform your doctor, as you will need to discuss the benefits and risks of using this medication during pregnancy.

Special Patient Groups

🀰

Pregnancy

Use during pregnancy only if the potential benefit justifies the potential risk to the fetus. Animal studies have shown developmental toxicity (skeletal abnormalities, growth retardation) at clinically relevant exposures. There is a pregnancy registry for women exposed to pregabalin during pregnancy.

Trimester-Specific Risks:

First Trimester: Potential for increased risk of major congenital malformations, particularly neural tube defects, based on some observational studies, though data are conflicting and limited.
Second Trimester: Limited data, but generally considered lower risk than first trimester for major malformations.
Third Trimester: Potential for neonatal withdrawal symptoms if discontinued abruptly near term. Risk of respiratory depression in neonates if used close to delivery.
🀱

Lactation

Pregabalin is excreted into human milk. The decision to breastfeed should consider the developmental and health benefits of breastfeeding, the mother’s clinical need for Lyrica CR, and any potential adverse effects on the breastfed infant from Lyrica CR or from the underlying maternal condition. Monitor infants for sedation and poor feeding.

Infant Risk: L3 (Moderately safe) - Monitor for sedation, poor feeding, and weight gain.
πŸ‘Ά

Pediatric Use

Safety and effectiveness of Lyrica CR in pediatric patients have not been established. Immediate-release pregabalin is approved for partial-onset seizures in pediatric patients 1 month and older, but not for neuropathic pain or fibromyalgia in this population.

πŸ‘΄

Geriatric Use

Elderly patients (β‰₯65 years) may have reduced renal function, requiring dose adjustment based on creatinine clearance. They may also be more susceptible to dizziness, somnolence, and peripheral edema. Start with lower doses and titrate slowly.

Clinical Information

πŸ’Ž

Clinical Pearls

  • Lyrica CR is an extended-release formulation designed for once-daily dosing, typically taken with the evening meal.
  • It is crucial to adjust the dose in patients with renal impairment; Lyrica CR is not recommended for severe renal impairment (CrCl <30 mL/min) or dialysis patients due to the difficulty in dose adjustment with the extended-release formulation.
  • Patients should be counseled on the risk of dizziness, somnolence, and peripheral edema, especially during initiation and dose titration.
  • Abrupt discontinuation can lead to withdrawal symptoms (insomnia, nausea, headache, anxiety, diarrhea), so taper slowly over at least 1 week.
  • Monitor for signs of suicidal ideation and behavior, particularly in patients with a history of depression or psychiatric disorders.
  • Be aware of the potential for abuse and dependence, especially in patients with a history of substance abuse. Pregabalin is a Schedule V controlled substance.
  • Lyrica CR is specifically indicated for DPN, PHN, and fibromyalgia. It is not interchangeable with immediate-release Lyrica on a mg-per-mg basis.
πŸ”„

Alternative Therapies

  • Gabapentin (immediate-release or extended-release formulations like Gralise, Horizant)
  • Duloxetine (Cymbalta)
  • Venlafaxine (Effexor XR)
  • Tricyclic antidepressants (e.g., amitriptyline, nortriptyline)
  • Topical analgesics (e.g., lidocaine patches, capsaicin cream)
  • Opioid analgesics (generally not first-line for chronic neuropathic pain)
  • Non-pharmacological therapies (e.g., physical therapy, exercise, cognitive behavioral therapy)
