Pharmacological Properties

Pharmacodynamics

Active substance – pregabalin, which is a structural analogue of gamma-aminobutyric acid

((S)-3-(aminomethyl)-5-methylhexanoic acid).

Pregabalin binds to the auxiliary subunit (α2-δ protein) of voltage-dependent calcium channels in the central nervous system and potently displaces [3H]-gabapentin in experimental settings.

Neuropathic Pain

The efficacy of the drug has been demonstrated in clinical studies on diabetic neuropathy, postherpetic neuralgia, and spinal cord injury. Efficacy in other types of neuropathic pain has not been studied.

Safety and efficacy profiles for dosing regimens of 2–3 times daily were similar.

Pain reduction was observed during the first week and maintained throughout the treatment period.

Epilepsy

Adjunctive therapy. Pregabalin was studied in three controlled clinical trials lasting 12 weeks with dosing regimens twice or three times daily. Overall, safety and efficacy profiles for twice-daily and three-times-daily regimens were similar. Reduction in seizure frequency was observed as early as the first week.

Generalized Anxiety Disorder

Pregabalin was studied in six controlled trials lasting 4–6 weeks, one 8-week trial involving elderly patients, and one long-term relapse prevention trial with a double-blind relapse prevention phase lasting 6 months.

Reduction in symptoms of generalized anxiety disorder according to the Hamilton Anxiety Rating Scale (HAM-A) was observed as early as week 1.

In controlled clinical trials (lasting 4–8 weeks), improvement of at least 50% in total HAM-A score from baseline to endpoint was observed in 52% of patients receiving pregabalin and in 38% of patients in the placebo group.

During controlled trials, blurred vision occurred more frequently in patients receiving pregabalin than in those receiving placebo. In most cases, this effect resolved with continued therapy. Ophthalmological examinations (including visual acuity testing, formal visual field testing, and fundus examination with dilated pupils) were performed in over 3600 patients during controlled clinical trials. Among these patients, visual acuity worsened in 6.5% of patients in the pregabalin group and in 4.8% in the placebo group. Visual field changes were observed in 12.4% of patients receiving pregabalin and in 11.7% of placebo group patients. Fundus changes were observed in 1.7% of patients receiving pregabalin and in 2.1% of patients in the placebo group.

Pharmacokinetics

Pharmacokinetic parameters of pregabalin were similar in healthy volunteers, patients with epilepsy taking antiepileptic drugs, and patients with chronic pain.

Absorption. Pregabalin is rapidly absorbed after oral administration on an empty stomach and reaches maximum plasma concentration within 1 hour after single and multiple doses. The calculated oral bioavailability of pregabalin is 90% or more and is dose-independent. Steady-state concentrations are achieved within 24–48 hours after repeated administration. The rate of pregabalin absorption is reduced when administered with food, resulting in approximately a 25–30% decrease in maximum concentration (Cmax) and an increase in time to reach maximum concentration (tmax) by about 2.5 hours. However, co-administration with food did not have a clinically significant effect on the extent of absorption.

Distribution. The apparent volume of distribution of pregabalin after oral administration is approximately 0.56 L/kg. Pregabalin does not bind to plasma proteins.

Metabolism. Pregabalin undergoes minimal metabolism. After administration of a radiolabeled dose of pregabalin, approximately 98% of radioactivity is excreted in urine as unchanged drug. The N-methylated derivative of pregabalin (the main metabolite detectable in urine) accounted for 0.9% of the administered dose. Studies have shown no racemization of the S-enantiomer to the R-enantiomer.

Elimination. Pregabalin is eliminated from systemic circulation primarily by renal excretion as unchanged drug. The mean elimination half-life of pregabalin is 6.3 hours. Plasma and renal clearance of pregabalin are directly proportional to creatinine clearance. Dose adjustment is required for patients with renal impairment or those undergoing hemodialysis.

Linearity/Non-linearity. Pregabalin pharmacokinetics are linear over the entire recommended dose range. Inter-subject pharmacokinetic variability for pregabalin is low (less than 20%). Pharmacokinetics of multiple doses are predictable based on single-dose data. Therefore, routine monitoring of plasma pregabalin concentrations is not necessary.

Pharmacokinetics in Specific Patient Populations

Gender. There is no clinically significant effect of gender on pregabalin plasma concentrations.

Renal Impairment. Pregabalin clearance is directly proportional to creatinine clearance. In addition, pregabalin is effectively removed from plasma by hemodialysis (after 4 hours of hemodialysis, plasma pregabalin concentrations decrease by approximately 50%). Since renal excretion is the main route of elimination, dose reduction is required for patients with renal impairment, and an additional dose should be administered after hemodialysis.

Hepatic Impairment. Specific pharmacokinetic studies in patients with hepatic impairment have not been conducted. Since pregabalin undergoes negligible metabolism and is primarily excreted unchanged in urine, it is unlikely that hepatic impairment would significantly affect pregabalin plasma concentrations.

Elderly Patients (over 65 years). Pregabalin clearance tends to decrease with age. This reduction in oral pregabalin clearance is consistent with the age-related decline in creatinine clearance. Dose reduction of pregabalin may be required for elderly patients with age-related renal impairment.

Clinical characteristics.

Indications.

Neuropathic pain.

Treatment of neuropathic pain in adults with damage to the peripheral and central nervous system.

Epilepsy.

Adjunctive therapy for partial seizures with or without secondary generalization in adults.

Generalized anxiety disorder.

Treatment of generalized anxiety disorder in adults.

Contraindications.

Hypersensitivity to the active substance or to any of the excipients.

Interaction with other medicinal products and other forms of interaction.

Since pregabalin is predominantly excreted unchanged in the urine, undergoes minimal metabolism in the human body (less than 2% of the dose is excreted in urine as metabolites), does not inhibit in vitro metabolism of other drugs, and does not bind to plasma proteins, it is unlikely that pregabalin may cause pharmacokinetic interactions or be a subject of such interactions.

In vivo studies and population pharmacokinetic analysis.

In in vivo studies, no clinically significant pharmacokinetic interaction between pregabalin and phenytoin, carbamazepine, valproic acid, lamotrigine, gabapentin, lorazepam, oxycodone, or ethanol was observed. Population pharmacokinetic analysis showed that oral antidiabetic agents, diuretics, insulin, phenobarbital, tiagabine, and topiramate do not have a clinically significant effect on pregabalin clearance.

Oral contraceptives, norethisterone and/or ethinylestradiol.

Concomitant administration of pregabalin with oral contraceptives, norethisterone and/or ethinylestradiol does not affect the steady-state pharmacokinetics of either agent.

Medicinal products affecting the CNS.

Pregabalin may potentiate the effects of ethanol and lorazepam. In the post-marketing period, cases of respiratory depression, coma, and fatal outcome have been reported in patients who took pregabalin together with opioids and/or other medicinal products that suppress CNS function. Pregabalin is likely to enhance cognitive and gross motor function impairment caused by oxycodone.

Interaction in elderly patients.

No specific pharmacodynamic interaction studies involving elderly volunteers have been conducted. Interaction studies have been performed only in adults.

Special precautions for use.

Patients with diabetes mellitus.

According to current clinical practice, some diabetic patients whose body weight has increased during pregabalin treatment may require adjustment of their antihyperglycemic medications.

Hypersensitivity reactions.

Hypersensitivity reactions, including angioedema, have been reported. If symptoms of angioedema such as facial swelling, perioral swelling, or swelling of the upper airways occur, pregabalin should be discontinued immediately.

Severe skin adverse reactions.

Rare cases of severe skin adverse reactions (SSARs), including Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), have been reported in association with pregabalin treatment, which may be life-threatening or fatal. When prescribing the medicinal product, patients should be informed about the signs and symptoms, and skin reactions should be closely monitored. If signs or symptoms suggestive of these reactions occur, pregabalin should be discontinued immediately and alternative treatment considered (if necessary).

Dizziness, somnolence, loss of consciousness, confusion, and psychiatric disturbances.

Pregabalin use has been associated with dizziness and somnolence, which may increase the risk of traumatic events (e.g., falls) in elderly patients. Loss of consciousness, confusion, and psychiatric disturbances have also been reported. Therefore, patients should be advised to exercise caution until they are aware of the potential effects of the medicinal product.

Visual disorders.

During clinical trials, blurred vision was reported more frequently in patients receiving pregabalin compared to those receiving placebo. In most cases, this effect resolved with continued treatment. In trials involving ophthalmological examinations, the incidence of decreased visual acuity and visual field changes was higher in patients receiving pregabalin compared to placebo; however, the incidence of ocular fundus changes was higher in the placebo group.

Post-marketing reports have included ocular adverse reactions such as vision loss, blurred vision, or other changes in visual acuity, many of which were transient. Symptoms related to the visual system may decrease or resolve after discontinuation of pregabalin.

Renal impairment.

Cases of renal impairment have been reported. In some instances, this effect was reversible after discontinuation of pregabalin.

Discontinuation of concomitant antiepileptic drugs.

There is insufficient data on discontinuing concomitant antiepileptic drugs after seizure control has been achieved with the addition of pregabalin to allow transition to pregabalin monotherapy.

Withdrawal symptoms.

Withdrawal symptoms have been observed in some patients after discontinuation of short- or long-term pregabalin treatment. Reported events include insomnia, headache, nausea, anxiety, diarrhea, flu-like symptoms, restlessness, depression, pain, seizures, hyperhidrosis, and dizziness. This information should be communicated to the patient prior to initiating treatment.

Seizures, including status epilepticus and generalized tonic-clonic seizures, may occur during pregabalin treatment or shortly after discontinuation.

There are no data regarding the frequency and severity of withdrawal symptoms associated with the duration of pregabalin use and its dosage when discontinuing long-term treatment.

Heart failure.

Cases of congestive heart failure have been reported in some patients taking pregabalin. This reaction was mostly observed during pregabalin treatment for neuropathic pain in elderly patients with cardiovascular disorders. Pregabalin should be used with caution in such patients. This condition may resolve upon discontinuation of pregabalin.

Treatment of central neuropathic pain due to spinal cord injury.

During treatment of central neuropathic pain due to spinal cord injury, the overall incidence of adverse reactions, particularly those affecting the central nervous system such as somnolence, was increased. This may be related to the additive effects of concomitant medications (e.g., antispastic agents) required for managing this condition. This factor should be considered when prescribing pregabalin to such patients.

Respiratory depression.

Cases of severe respiratory depression have been reported in association with pregabalin use. Patients with impaired respiratory function, respiratory or neurological disorders, renal impairment, concomitant use of CNS depressants, and elderly patients may be at higher risk for this serious adverse reaction. Dose adjustment may be required for these patients.

Suicidal thoughts and behavior.

Cases of suicidal thoughts and behavior have been reported in patients receiving antiepileptic drugs for various indications. A meta-analysis of randomized placebo-controlled trials of antiepileptic drugs also showed a small increased risk of suicidal thoughts and behavior. The mechanism of this risk is unknown. Post-marketing reports have documented cases of suicidal thoughts and behavior in patients receiving pregabalin (see section "Adverse reactions"). An epidemiological study using a self-controlled design (comparing treatment periods with non-treatment periods within individual patients) demonstrated an increased risk of new-onset suicidal behavior and fatal outcomes due to suicide in patients receiving pregabalin.

Patients (and caregivers) should seek medical help if signs of suicidal thoughts or behavior emerge. Patients should be monitored for signs of suicidal thoughts and behavior, and appropriate treatment should be considered. If suicidal thoughts or behavior occur, discontinuation of pregabalin therapy should be considered.

Worsening of lower gastrointestinal tract function.

Post-marketing reports have described worsening of lower gastrointestinal tract function (e.g., intestinal obstruction, paralytic ileus, constipation) associated with pregabalin use in combination with medications that may cause constipation, such as opioid analgesics. When pregabalin is used concomitantly with opioids, preventive measures for constipation should be implemented (especially in women and elderly patients).

Concomitant use with opioids.

Caution is recommended when prescribing pregabalin concomitantly with opioids due to the risk of CNS depression (see section "Interaction with other medicinal products and other forms of interaction"). In a case-control study of opioid users, an increased risk of opioid-related mortality was observed in patients receiving pregabalin in addition to an opioid compared to those receiving opioids alone (adjusted odds ratio [aOR], 1.68 [95% CI, 1.19–2.36]). This increased risk was observed at low pregabalin doses (≤ 300 mg, aOR 1.52 [95% CI, 1.04–2.22]) with a trend toward increased risk at higher pregabalin doses (> 300 mg, aOR 2.55 [95% CI, 1.24–5.06]).

Misuse, abuse, or dependence.

Cases of misuse, abuse, and dependence have been reported. The drug should be used with caution in patients with a history of substance abuse; patients should be monitored for signs of misuse, abuse, or dependence on pregabalin (cases of addiction, dose escalation, and drug-seeking behavior have been reported).

Encephalopathy.

Cases of encephalopathy occurred predominantly in patients with comorbid conditions that may predispose to encephalopathy.

Lactose intolerance.

The product contains lactose monohydrate. Patients with rare hereditary problems such as galactose intolerance, Lapp lactase deficiency, or glucose-galactose malabsorption should not take this medicine.

Use during pregnancy or breastfeeding.

Women of childbearing potential/contraception in women and men.

Since the potential risk to humans is unknown, women of childbearing potential should use effective contraception.

Pregnancy.

There are no reliable data on the use of pregabalin in pregnant women.

Animal studies have shown reproductive toxicity. The potential risk to humans is unknown.

Pregabalin (Pagamax) should not be used during pregnancy except in exceptional cases where the benefit to the pregnant woman clearly outweighs the potential risk to the fetus.

Breastfeeding.

A small amount of pregabalin has been detected in breast milk. Women who are breastfeeding should be informed that breastfeeding is not recommended during pregabalin treatment.

Reproductive function.

There are no clinical data on the effect of pregabalin on female reproductive function.

In a clinical study assessing the effect of pregabalin on sperm motility in healthy male volunteers, a dose of 600 mg daily was administered. After three months of treatment, no effect on sperm motility was observed.

Ability to affect reaction speed when driving or operating machinery.

The medicinal product may have a slight or moderate influence on the ability to drive or operate machinery. Pagamax may cause dizziness and somnolence and may affect the ability to drive vehicles or operate machinery. Therefore, patients should be advised to refrain from driving vehicles or operating complex machinery or engaging in any potentially hazardous activities until it is known whether this medicinal product affects their ability to perform such tasks.

Dosage and Administration

For oral use.

Doses

The dose range may vary between 150–600 mg per day. The daily dose should be divided into 2 or 3 doses.

Neuropathic pain.

Treatment with pregabalin may be initiated at a dose of 150 mg per day, divided into 2 or 3 doses. Depending on efficacy and individual tolerability, the dose may be increased to 300 mg per day after an interval of 3 to 7 days, and if necessary, to the maximum dose of 600 mg per day after an additional 7-day interval.

Epilepsy.

Treatment with pregabalin may be initiated at a dose of 150 mg per day, divided into 2 or 3 doses. Depending on efficacy and individual tolerability, the dose may be increased to 300 mg per day after the first week of treatment. After another week, the dose may be increased to the maximum of 600 mg per day.

Generalized anxiety disorder.

The daily dose, divided into 2 or 3 doses, may range from 150 to 600 mg per day. The need for continued treatment should be periodically reassessed.

Treatment with pregabalin may be initiated at a dose of 150 mg per day. Depending on efficacy and individual tolerability, the dose may be increased to 300 mg per day after the first week of treatment. After another week, the dose may be increased to 450 mg per day. Following an additional week, the dose may be increased to the maximum of 600 mg per day.

Discontinuation of pregabalin treatment.

According to current clinical practice, pregabalin treatment should be discontinued gradually over a period of at least one week, regardless of the indication.

Patients with renal impairment.

Pregabalin is eliminated from systemic circulation in unchanged form primarily via renal excretion. Since pregabalin clearance is directly proportional to creatinine clearance (CrCl), dosage adjustment in patients with impaired renal function should be individualized according to creatinine clearance (CrCl), as indicated in the table below and calculated using the following formula:

CrCl (mL/min) =

(

Pregabalin is effectively removed from plasma by hemodialysis (approximately 50% of the drug is eliminated within 4 hours). For patients undergoing hemodialysis, the daily dose of pregabalin should be adjusted according to renal function. In addition to the daily dose, an extra dose of the drug should be administered immediately after each 4-hour hemodialysis session (see table).

Dosage adjustment of pregabalin according to renal function

Creatinine clearance (CLcr), (mL/min)	Total daily dose of pregabalin *		Dosing regimen
	Initial dose (mg/day)	Maximum dose (mg/day)
≥ 60	150	600	2-3 times daily
≥ 30–< 60	75	300	2-3 times daily
≥ 15–< 30	25-50	150	1-2 times daily
< 15	25	75	Once daily
Additional dose after hemodialysis (mg)
	25	100	Single dose

* The total daily dose (mg/day) should be divided by the number of doses according to the dosing regimen in order to obtain the single dose (mg/dose).

Patients with hepatic impairment.

Dose adjustment is not required for patients with hepatic impairment.

Use in elderly patients (over 65 years).

For elderly patients, dose reduction of pregabalin may be necessary due to impaired renal function (see section "Dosage and Administration").

The medication should be taken independently of food intake.

Children.

The safety and efficacy of pregabalin in children (under 18 years of age) have not been established.

Overdose.
