Cerebrolysin is a prescription medicine registered in Ukraine, based on a hydrolysate of pig brain; per the manufacturer's leaflet it is given by injection (intramuscularly or intravenously) at a dose of roughly 5–30 mL per day in a course of 10–20 days, and the approximate price at Ukrainian pharmacies is about 800–1700 UAH per pack depending on the ampoule dosage. Below is a concise, fact-checked reference: what it is, how it is used according to the official leaflet, how much it costs, what the evidence base actually says, and which approaches people consider when they search for "what to replace Cerebrolysin with." Let us state the main thing right away: all decisions about using prescription drugs are made by a doctor, and self-treatment with injectable agents is dangerous.

What Cerebrolysin is

Cerebrolysin is an aqueous solution of a mixture of low-molecular-weight peptides and free amino acids obtained from standardized purified pig brain protein. The manufacturer is EVER Neuro Pharma (Austria). The drug is positioned as a neurotropic (neurometabolic) agent, and the leaflet lists among its indications ischemic stroke, traumatic brain injury, and dementia (including vascular and Alzheimer's type). It is important to understand: this is a biological product of animal origin, not a single "pure" molecule, so its composition is described as a standardized hydrolysate rather than a single active substance with known pharmacokinetics.

In brief: the facts

  • What it is: a neuropeptide hydrolysate from purified pig brain (peptides < ~10 kDa + amino acids).
  • Manufacturer: EVER Neuro Pharma (Austria).
  • Form: a solution for injection; ampoules of 1, 2, 5, 10, 20 mL (concentration 215.2 mg/mL) and a 30 mL vial.
  • Dose per the leaflet: usually 5–30 mL per day (more for more severe indications and drip administration).
  • Route of administration: intramuscularly (up to 5 mL), intravenously as a bolus (up to 10 mL), intravenously by drip (diluted in saline).
  • Course: usually 10–20 days daily; repeated if needed.
  • Status in Ukraine: a registered prescription medicine.
  • Price (approximate): ~800–1700 UAH per pack, check the current one on tabletki.ua or at a pharmacy.
  • Evidence base: contradictory (see the Cochrane section below).

Leaflet and dosing: how it is used

Per the official leaflet (the State Register of Medicinal Products of Ukraine, Cerebrolysin's registration dossier) the daily dose usually ranges within 5–30 mL, depending on the indication and severity of the condition; for severe indications and drip administration the leaflet allows larger volumes. The course is about 10–20 days of daily injections, after which the doctor prescribes repeat courses if needed (often 2–3 times a year).

As for the query "how to inject Cerebrolysin": per the leaflet, smaller volumes (up to 5 mL) can be given intramuscularly, up to 10 mL intravenously as a slow bolus, and larger doses only intravenously by drip diluted in standard infusion solutions. Rapid administration can cause a feeling of heat or dizziness. We stress: this is a prescription injectable agent, and its prescription, dose, and route of administration are determined by a doctor; the injections themselves are performed by a medical professional or done under medical supervision. The figures given are a restatement of the official leaflet, not a recommendation to inject the drug on your own.

Another common question is "Cerebrolysin in tablets." An important factual detail: the drug is produced only in injectable form (a solution in ampoules and vials); there are no oral tablets or capsules of Cerebrolysin, because the peptides would break down in the digestive tract. So any "Cerebrolysin tablets" on sale are not the same agent. Likewise, do not rely on "Cerebrolysin without a prescription": as a prescription drug it requires a doctor's order, and dispensing without a prescription is a violation, not a convenience.

How much Cerebrolysin costs at Ukrainian pharmacies

The price depends on the ampoule dosage (1, 2, 5, 10, 20 mL) and the quantity in the pack. Approximately, on pharmacy aggregators such as tabletki.ua a pack of Cerebrolysin costs about 800–1700 UAH; larger ampoules (10 mL) and larger packs are more expensive. These figures are approximate and change, so the current price is worth checking directly at a pharmacy or an aggregator before buying. Since the drug is prescription-only, purchasing it requires a doctor's order.

What the evidence base says (important)

Honesty is needed here. Despite a long history of use in post-Soviet countries, there is not much quality independent evidence for Cerebrolysin's efficacy, and some of the studies are old or sponsored by the manufacturer.

  • Acute ischemic stroke. A Cochrane systematic review (Ziganshina LE et al., 2023 update) found no convincing evidence of benefit: the drug probably has little to no effect on survival in the acute phase, and conclusions about serious adverse events remain cautious; most of the included trials were funded by the manufacturer.
  • Vascular dementia. A Cochrane review (Cui S et al., 2019) concluded that the available data may hint at a benefit for cognitive and global function, but they are insufficient for unambiguous recommendations; adequately designed and methodologically sound trials are needed.

In other words, Cerebrolysin is an example of an agent with a limited and contradictory evidence base. This does not mean it "does not work," but it does mean that confident evidence of benefit is lacking, and any decisions should be made together with a doctor.

Contraindications and side effects

Per the leaflet, Cerebrolysin is contraindicated in hypersensitivity to the components, severe renal failure, and status epilepticus (there is a risk of lowering the seizure threshold). Use with caution in pregnancy and breastfeeding. Among the possible adverse reactions are local reactions at the injection site, a feeling of heat, sweating, dizziness, agitation or insomnia (especially with too-rapid administration), and, less often, allergic reactions. This is another reason the drug is used under a doctor's supervision rather than on your own.

What to replace Cerebrolysin with

When people search for "what to replace Cerebrolysin with," they usually mean other registered neurotropic agents with similar positioning, for example, cortexin (polypeptides), actovegin or solcoseryl (hemoderivatives), citicoline or choline alfoscerate preparations. Important: the evidence base of many of them is also limited or debatable, and the choice and appropriateness of any replacement is a question for a doctor, not an independent decision.

Separately, about the research context. In the scientific literature the synthetic regulatory neuropeptides Semax (an analogue of the ACTH 4–10 fragment) and Selank (an analogue of tuftsin) attract attention. They are studied as tools for preclinical and laboratory research into neuropeptide regulation; we gathered more detail on the mechanisms, history, and available data in the Semax monograph. But let us be honest: quality indexed RCTs (randomized controlled trials) for these compounds are scarce, most publications are old or Russian-language, and they justify no medical claims about "replacing" Cerebrolysin.

Longeva supplies Semax and Selank solely as research raw material (research-use-only), they are not medicines, they are not intended for diagnosis, treatment, or human consumption. When it comes to a specific person's health, that is the territory of a doctor and registered drugs, not research reagents.
