buy Pregabalin online, sold under the brand name Lyrica among others, is an anticonvulsant, analgesic and anxiolytic medication used to treat epilepsy, neuropathic pain, fibromyalgia, restless leg syndrome, opioid withdrawal and generalized anxiety disorder (GAD). Pregabalin also has antiallodynic properties. Its use in epilepsy is as an add-on therapy for partial seizures. It is a gabapentinoid medication. When used before surgery, it reduces pain but results in greater sedation and visual disturbances. It is taken by mouth. Buy Pregabalin powder CAS 148553-50-8

Common side effects include headache, dizziness, sleepiness, confusion, trouble with memory, poor coordination, dry mouth, problem with vision, and weight gain. Serious side effects may include angioedema, drug misuse, and an increased suicide risk. When pregabalin is taken at high doses over a long period of time, addiction may occur, but if taken at usual doses the risk is low. Use during pregnancy or breastfeeding is of unclear safety. Pregabalin is a gabapentinoid and acts by inhibiting certain calcium channels. Buy Pregabalin powder CAS 148553-50-8

Pregabalin was approved for medical use in the United States in 2004. It was developed as a successor to be related to gabapentin. It is available as a generic medication in a number of countries, including the United States as of 2019. A generic version of the extended-release formulation is available in the United States as of April 2021. In 2019, it was the 81st most commonly prescribed medication in the United States, with more than 9 million prescriptions.In the US, pregabalin is a Schedule V controlled substance under the Controlled Substances Act of 1970. It is a Class C controlled substance in the UK. Buy Pregabalin powder CAS 148553-50-8


Seizures  Pregabalin powder CAS 148553-50-8

Pregabalin is useful when added to other treatments, when those other treatments are not controlling partial epilepsy. Its use alone is less effective than some other seizure medications. It is unclear how it compares to gabapentin for this use. Buy Pregabalin powder CAS 148553-50-8
Neuropathic pain

The European Federation of Neurological Societies recommends pregabalin as a first line agent for the treatment of pain associated with diabetic neuropathy, post-herpetic neuralgia, and central neuropathic pain. A minority obtain substantial benefit, and a larger number obtain moderate benefit. It is given equal weight as gabapentin and tricyclic antidepressants as a first line agent, however the latter are less expensive as of 2010. Sell Pregabalin Cas:148553-50-8

Studies have shown that higher doses of pregabalin are associated with greater efficacy. Buy Pregabalin powder CAS 148553-50-8

Pregabalin’s use in cancer-associated neuropathic pain is controversial;] though such use is common. It has been examined for the prevention of post-surgical chronic pain, but its utility for this purpose is controversial.

Pregabalin is generally not regarded as efficacious in the treatment of acute pain. In trials examining the utility of pregabalin for the treatment of acute post-surgical pain, no effect on overall pain levels was observed, but people did require less morphine and had fewer opioid-related side effects. Several possible mechanisms for pain improvement have been discussed. Buy Pregabalin powder CAS 148553-50-8

Anxiety disorders of  Pregabalin powder CAS 148553-50-8

Pregabalin is moderately effective and is safe for treatment of generalized anxiety disorder. Sell Pregabalin Cas:148553-50-8

The World Federation of Biological Psychiatry recommends pregabalin as one of several first line agents for the treatment of generalized anxiety disorder, but recommends other agents such as SSRIs as first line treatment for obsessive–compulsive disorder and post-traumatic stress disorder. It appears to have anxiolytic effects similar to benzodiazepines with less risk of dependence. Buy Pregabalin powder CAS 148553-50-8

The effects of pregabalin appear after one week of use, and are similar in effectiveness to lorazepam, alprazolam, and venlafaxine, but pregabalin has demonstrated superiority by producing more consistent therapeutic effects for psychosomatic anxiety symptoms. Long-term trials have shown continued effectiveness without the development of tolerance, and, in addition, unlike benzodiazepines, it has a beneficial effect on sleep and sleep architecture, characterized by the enhancement of slow-wave sleep. It produces less severe cognitive and psychomotor impairment compared to benzodiazepines. Buy Pregabalin powder CAS 148553-50-8

A 2019 review found that pregabalin reduces symptoms and was generally well tolerated.

Other uses of  Pregabalin powder CAS 148553-50-8

There is no evidence and significant risk in using pregabalin for sciatica and low back pain. Evidence of benefit in alcohol withdrawal as well as withdrawal from certain other drugs is limited as of 2016. Sell Pregabalin Cas:148553-50-8

Adverse effects of Pregabalin powder CAS 148553-50-8

Exposure to pregabalin is associated with weight gain, sleepiness and fatigue, dizziness, vertigo, leg swelling, disturbed vision, loss of coordination, and euphoria. It has an adverse effect profile similar to other central nervous system depressants. Adverse drug reactions associated with the use of pregabalin include:Buy Pregabalin powder CAS 148553-50-8

Very common (>10% of people with pregabalin): dizziness, drowsiness.
Common (1–10% of people with pregabalin): blurred vision, diplopia, increased appetite and subsequent weight gain, euphoria, confusion, vivid dreams, changes in libido (increase or decrease), irritability, ataxia, attention changes, feeling high, abnormal coordination, memory impairment, tremors, dysarthria, parasthesia, vertigo, dry mouth and constipation, vomiting and flatulence, erectile dysfunction, fatigue, peripheral edema, feeling the effects of drunkenness, abnormal walking, asthenia, nasopharyngitis, increased creatine kinase level. Sell Pregabalin Cas:148553-50-8

Withdrawal symptoms of Pregabalin powder CAS 148553-50-8

Following abrupt or rapid discontinuation of pregabalin, some people reported symptoms suggestive of physical dependence. The FDA determined that the substance dependence profile of pregabalin, as measured by a personal physical withdrawal checklist, was quantitatively less than benzodiazepines. Even people who have discontinued short term use of pregabalin have experienced withdrawal symptoms, including insomnia, headache, nausea, anxiety, diarrhea, flu like symptoms, nervousness, major depression, pain, convulsions, hyperhidrosis and dizziness. Buy Pregabalin powder CAS 148553-50-8

It is unclear if it is safe for use in pregnancy with some studies showing potential harm.

Breathing Pregabalin powder CAS 148553-50-8

In December 2019, the U.S. Food and Drug Administration (FDA) warned about serious breathing issues for those taking gabapentin or pregabalin when used with CNS depressants or for those with lung problems.

The FDA required new warnings about the risk of respiratory depression to be added to the prescribing information of the gabapentinoids. The FDA also required the drug manufacturers to conduct clinical trials to further evaluate their abuse potential, particularly in combination with opioids, because misuse and abuse of these products together is increasing, and co-use may increase the risk of respiratory depression. Sell Pregabalin Cas:148553-50-8

Among 49 case reports submitted to the FDA over the five-year period from 2012 to 2017, twelve people died from respiratory depression with gabapentinoids, all of whom had at least one risk factor. Buy Pregabalin powder CAS 148553-50-8

The FDA reviewed the results of two randomized, double-blind, placebo-controlled clinical trials in healthy people, three observational studies, and several studies in animals. One trial showed that using pregabalin alone and using it with an opioid pain reliever can depress breathing function. The other trial showed gabapentin alone increased pauses in breathing during sleep. The three observational studies at one academic medical center showed a relationship between gabapentinoids given before surgery and respiratory depression occurring after different kinds of surgeries. The FDA also reviewed several animal studies that showed pregabalin alone and pregabalin plus opioids can depress respiratory function. Buy Pregabalin powder CAS 148553-50-8

Overdose of Pregabalin powder CAS 148553-50-8

An overdose of Pregabalin usually consists of severe drowsiness, severe ataxia, blurred vision, slurred speech, severe uncontrollable jerking motions, and anxiety. Despite these symptoms an overdose is not usually fatal unless mixed with another depressant. Several people with kidney failure developed myoclonus while receiving pregabalin, apparently as a result of gradual accumulation of the drug. Acute overdosage may be manifested by somnolence, tachycardia and hypertonia. Plasma, serum or blood concentrations of pregabalin may be measured to monitor therapy or to confirm a diagnosis of poisoning in hospitalized people. Buy Pregabalin powder CAS 148553-50-8

Pharmacology of Pregabalin powder CAS 148553-50-8

No interactions have been demonstrated in vivo. The manufacturer notes some potential pharmacological interactions with opioids, benzodiazepines, barbiturates, ethanol (alcohol), and other drugs that depress the central nervous system. ACE inhibitors may enhance the adverse/toxic effect of pregabalin. Pregabalin may enhance the fluid-retaining effect of certain anti-diabetic agents (thiazolidinediones). Buy Pregabalin powder CAS 148553-50-8

Pharmacodynamics of Pregabalin powder CAS 148553-50-8

Pregabalin is not a GABAA or GABAB receptor agonist.
Pregabalin is a gabapentinoid and acts by inhibiting certain calcium channels.Specifically it is a ligand of the auxiliary α2δ subunit site of certain voltage-dependent calcium channels (VDCCs), and thereby acts as an inhibitor of α2δ subunit-containing VDCCs.There are two drug-binding α2δ subunits, α2δ-1 and α2δ-2, and pregabalin shows similar affinity for (and hence lack of selectivity between) these two sites. Pregabalin is selective in its binding to the α2δ VDCC subunit. Despite the fact that pregabalin is a GABA analogue, it does not bind to the GABA receptors, does not convert into GABA or another GABA receptor agonist in vivo, and does not directly modulate GABA transport or metabolism. However, pregabalin has been found to produce a dose-dependent increase in the brain expression of L-glutamic acid decarboxylase (GAD), the enzyme responsible for synthesizing GABA, and hence may have some indirect GABAergic effects by increasing GABA levels in the brain. There is currently no evidence that the effects of pregabalin are mediated by any mechanism other than inhibition of α2δ-containing VDCCs. In accordance, inhibition of α2δ-1-containing VDCCs by pregabalin appears to be responsible for its anticonvulsant, analgesic, and anxiolytic effects. Buy Pregabalin powder CAS 148553-50-8

The endogenous α-amino acids L-leucine and L-isoleucine, which closely resemble pregabalin and the other gabapentinoids in chemical structure, are apparent ligands of the α2δ VDCC subunit with similar affinity as the gabapentinoids (e.g., IC50 = 71 nM for L-isoleucine), and are present in human cerebrospinal fluid at micromolar concentrations (e.g., 12.9 μM for L-leucine, 4.8 μM for L-isoleucine). It has been theorized that they may be the endogenous ligands of the subunit and that they may competitively antagonize the effects of gabapentinoids. In accordance, while gabapentinoids like pregabalin and gabapentin have nanomolar affinities for the α2δ subunit, their potencies in vivo are in the low micromolar range, and competition for binding by endogenous L-amino acids has been said to likely be responsible for this discrepancy. Buy Pregabalin powder CAS 148553-50-8

Pregabalin was found to possess 6-fold higher affinity than gabapentin for α2δ subunit-containing VDCCs in one study. However, another study found that pregabalin and gabapentin had similar affinities for the human recombinant α2δ-1 subunit (Ki = 32 nM and 40 nM, respectively). In any case, pregabalin is 2 to 4 times more potent than gabapentin as an analgesic and, in animals, appears to be 3 to 10 times more potent than gabapentin as an anticonvulsant. Buy Pregabalin powder CAS 148553-50-8

Pharmacokinetics of Pregabalin powder CAS 148553-50-8

Pregabalin is absorbed from the intestines by an active transport process mediated via the large neutral amino acid transporter 1 (LAT1, SLC7A5), a transporter for amino acids such as L-leucine and L-phenylalanine. Very few (less than 10 drugs) are known to be transported by this transporter. Unlike gabapentin, which is transported solely by the LAT1, pregabalin seems to be transported not only by the LAT1 but also by other carriers. The LAT1 is easily saturable, so the pharmacokinetics of gabapentin are dose-dependent, with diminished bioavailability and delayed peak levels at higher doses. In contrast, this is not the case for pregabalin, which shows linear pharmacokinetics and no saturation of absorption. Buy Pregabalin powder CAS 148553-50-8

The oral bioavailability of pregabalin is greater than or equal to 90% across and beyond its entire clinical dose range (75 to 900 mg/day). Food does not significantly influence the oral bioavailability of pregabalin. Pregabalin is rapidly absorbed when administered on an empty stomach, with a Tmax (time to peak levels) of generally less than or equal to 1 hour at doses of 300 mg or less. However, food has been found to substantially delay the absorption of pregabalin and to significantly reduce peak levels without affecting the bioavailability of the drug; Tmax values for pregabalin of 0.6 hours in a fasted state and 3.2 hours in a fed state (5-fold difference), and the Cmax is reduced by 25–31% in a fed versus fasted state. Buy Pregabalin powder CAS 148553-50-8

Distribution of Pregabalin powder CAS 148553-50-8

Pregabalin crosses the blood–brain barrier and enters the central nervous system. However, due to its low lipophilicity, pregabalin requires active transport across the blood–brain barrier. The LAT1 is highly expressed at the blood–brain barrier and transports pregabalin across into the brain. Pregabalin has been shown to cross the placenta in rats and is present in the milk of lactating rats. In humans, the volume of distribution of an orally administered dose of pregabalin is approximately 0.56 L/kg. Pregabalin is not significantly bound to plasma proteins (<1%). Buy Pregabalin powder CAS 148553-50-8

Metabolism of Pregabalin powder CAS 148553-50-8

Pregabalin undergoes little or no metabolism.In experiments using nuclear medicine techniques, it was revealed that approximately 98% of the radioactivity recovered in the urine was unchanged pregabalin. The main metabolite is N-methylpregabalin. Buy Pregabalin powder CAS 148553-50-8

Elimination of Pregabalin powder CAS 148553-50-8

Pregabalin is eliminated by the kidneys in the urine, mainly in its unchanged form. It has a relatively short elimination half-life, with a reported value of 6.3 hours. Because of its short elimination half-life, pregabalin is administered 2 to 3 times per day to maintain therapeutic levels. The kidney clearance of pregabalin is 73 mL/minute. Buy Pregabalin powder CAS 148553-50-8
