What is Centurion Laboratories?

CENTURION LABORATORIES is an Indian pharmaceutical company whose name often appears in Ukrainian pharmacy catalogs as a separate product item, although in reality, it refers to the manufacturer rather than a single medicinal product with a constant composition. The company has been operating in the market since the mid-1990s and specializes in the production of generics — drugs containing the same active substances as the original brands, but manufactured after the expiration of patent protection. The manufacturing sites of CENTURION LABORATORIES are located in the state of Gujarat and are certified in accordance with GMP (Good Manufacturing Practice) standards, which regulate the purity of raw materials, control of each batch, and stability of the finished form. That is why the products of this enterprise are considered an economically affordable alternative to original agents, provided that the specific product name is chosen correctly.

The most famous product lines manufactured by CENTURION LABORATORIES belong to the pharmacological group of phosphodiesterase type 5 (PDE-5) inhibitors — these are drugs based on sildenafil, tadalafil, and vardenafil. A separate group consists of combination agents in which a PDE-5 inhibitor is combined with dapoxetine, a short-acting selective serotonin reuptake inhibitor. The company's portfolio also includes products for the treatment of benign prostatic hyperplasia, hormonal drugs, and certain items of a general therapeutic profile. Thus, dozens of medicines of different compositions, each with its own instructions, are combined under a single manufacturer's name.

The main release form of CENTURION LABORATORIES products is film-coated tablets packaged in blisters of 4, 10, or 12 pieces. There are also dispersible (chewable) tablets that dissolve in the oral cavity, jelly-like sachets, and, less frequently, oral solutions. Each dosage is marked with a numerical index in the name, corresponding to the number of milligrams of the active substance, which significantly simplifies the selection of therapy. Before starting the use of any product from this manufacturer, a doctor's consultation is mandatory, as self-determination of the dose by the name on the package does not replace a clinical examination.

What is Centurion Laboratories prescribed for?

The key indication for most drugs of this manufacturer is erectile dysfunction, which is the persistent inability to achieve or maintain an erection sufficient for sexual intercourse. PDE-5 inhibitors are effective in vascular, neurogenic, psychogenic, and mixed forms of the disorder, particularly in patients with type 2 diabetes mellitus, arterial hypertension, and after surgical interventions on pelvic organs. The drugs are not aphrodisiacs and do not increase libido — they work exclusively against the background of natural sexual arousal. The effectiveness of therapy is evaluated after several attempts of use, rather than by the result of a single dose.

The second common indication is premature ejaculation, for the correction of which combination forms with dapoxetine are prescribed. This component prolongs the intravaginal ejaculatory latency time by affecting the serotonergic mechanisms regulating the ejaculation reflex. Combination tablets are convenient because they allow for the simultaneous resolution of two problems that often accompany each other and increase patient anxiety. The prescription of such agents requires the prior exclusion of inflammatory prostate diseases and hormonal disorders.

Certain items of the CENTURION LABORATORIES assortment are used for benign prostatic hyperplasia — tadalafil in a low daily dosage reduces lower urinary tract symptoms, including frequent nighttime urination and the sensation of incomplete bladder emptying. Another area of application is pulmonary arterial hypertension, in which sildenafil in a special dosage regimen reduces pressure in the pulmonary circulation. The manufacturer's hormonal drugs are used in replacement therapy for laboratory-confirmed testosterone deficiency. Each of these indications requires separate diagnosis and medical supervision.

Composition and active components of Centurion Laboratories

Sildenafil citrate is the most common active substance in the company's products, presented in dosages from 25 to 200 mg. The mechanism of action consists in blocking the PDE-5 enzyme, which destroys cyclic guanosine monophosphate (cGMP) in the smooth muscles of the penile vessels. The accumulation of cGMP leads to relaxation of the vascular wall, increased blood flow to the corpora cavernosa, and the formation of an erection. The action begins within 30–60 minutes and lasts for approximately 4–5 hours.

Tadalafil in doses of 2.5–80 mg is distinguished by a long half-life — up to 17.5 hours, due to which the clinical effect is maintained for up to 36 hours. Vardenafil (10–20 mg) has higher selectivity for the enzyme and a faster onset of action, making it convenient for patients with concomitant diabetes. Dapoxetine (30–60 mg) in combination forms acts briefly: the maximum concentration is reached within an hour, and the substance is excreted almost completely within 24 hours, minimizing accumulation in the body.

Excipients of the tablets include microcrystalline cellulose as a filler, croscarmellose sodium for rapid disintegration of the tablet in the stomach, magnesium stearate as an anti-friction agent, lactose monohydrate, as well as colorants and hypromellose in the film coating. The presence of lactose is important for individuals with hereditary galactose intolerance or lactase deficiency. Colorants can provoke hypersensitivity reactions in individual patients. The complete list of components is always provided in the leaflet of the specific package.

Dosage of Centurion Laboratories

For sildenafil preparations, the starting dose for most adult men is considered to be 50 mg as needed, approximately one hour before sexual intimacy. Depending on tolerability and clinical effect, the doctor may reduce the dose to 25 mg or increase it to 100 mg, which is the maximum daily amount. Administration more than once a day is not allowed due to the risk of cumulative effect on vascular tone. High-dose forms (150 and 200 mg) have no proven benefits and significantly increase the probability of adverse reactions.

Tadalafil is used in two regimens: on-demand at 10–20 mg before intimacy or daily at 2.5–5 mg to maintain a stable level of the substance in the blood. Vardenafil is prescribed at 10 mg, with possible adjustment to 5 or 20 mg. Dapoxetine in combination tablets is taken 1–3 hours before the act, starting with 30 mg. The duration of the course is determined by the doctor — with a daily regimen, the effect is evaluated after 4–12 weeks.

Dose adjustment is necessary for patients over 65 years of age, individuals with renal impairment (creatinine clearance less than 30 ml/min), and hepatic pathology — in such cases, the minimum starting dose is recommended. Concomitant use of CYP3A4 inhibitors, particularly ketoconazole or ritonavir, also requires a reduction in the amount of the active substance. The body's individual response may differ even with the same diagnoses and similar body weight. Increasing the dose on one's own without consulting a specialist is unacceptable.

How to take Centurion Laboratories correctly?

The tablet is swallowed whole, without chewing or crushing, with a glass of plain still water. Fatty food slows down the absorption of sildenafil and vardenafil, so it is optimal to take them on an empty stomach or two hours after a light meal. Tadalafil is less dependent on the dietary regimen and can be taken regardless of food intake. Dispersible forms are dissolved in the mouth without water — they are suitable for patients with swallowing difficulties.

Since most drugs are taken on-demand, the concept of a "missed dose" does not apply to them. In the case of a daily tadalafil regimen, the missed tablet is taken as soon as remembered, but the dose is not doubled the next day. Grapefruit juice increases the concentration of the active substance in plasma and can cause an overdose, so it is excluded during therapy. Before the first intake, it is advisable to measure blood pressure and ensure the absence of cardiac contraindications.

Side effects of Centurion Laboratories

The most common adverse reactions are caused by the vasodilatory effect: headache, facial flushing, nasal congestion, dyspepsia, and heartburn. These manifestations are usually mild, resolve on their own within a few hours, and do not require discontinuation of the drug. Dizziness, back and muscle pain, color vision disorders in the form of a bluish tint, and temporary blurred vision are observed uncommonly. Dapoxetine can additionally cause nausea, somnolence, insomnia, and increased sweating.

Rare but serious conditions include priapism — a painful erection lasting more than 4 hours, sudden loss of hearing or vision, pronounced arterial hypotension, fainting, and allergic reactions with facial swelling. The appearance of any of these symptoms requires immediate medical attention. You should also stop taking the drug and consult a doctor if chest pain occurs during or after sexual intercourse. Orthostatic hypotension against the background of dapoxetine requires caution when standing up quickly.

Contraindications of Centurion Laboratories

An absolute contraindication is the concomitant use of any nitrates (nitroglycerin, isosorbide dinitrate) and nitric oxide donors — such a combination can cause a critical drop in blood pressure. The drugs are not prescribed in case of individual hypersensitivity to the components, myocardial infarction or stroke suffered within the last 6 months, severe heart failure, unstable angina, or uncorrected arrhythmias. Hereditary pigmentary retinal degeneration and a history of anterior ischemic optic neuropathy also exclude the use of PDE-5 inhibitors. Severe hepatic impairment of Child-Pugh class C is another barrier.

Relative contraindications include anatomical deformations of the penis, predisposition to priapism in sickle cell anemia, myeloma or leukemia, active peptic ulcer disease, and predisposition to bleeding. Products of this category are not intended for women, as well as children and adolescents under 18 years of age. During pregnancy and lactation, such agents are not used due to the lack of safety data. In elderly patients, therapy is started with minimum doses under the control of hemodynamic parameters.

Interaction of Centurion Laboratories with other drugs and alcohol

Clinically significant interaction is noted with alpha-blockers (tamsulosin, doxazosin) prescribed for prostate adenoma — concomitant use requires an interval of at least 4 hours. Azole antifungals, macrolide antibiotics, and HIV protease inhibitors increase the concentration of the active substance, while rifampicin and antiepileptic drugs decrease it. The combination of dapoxetine with SSRI antidepressants or MAO inhibitors is prohibited due to the risk of serotonin syndrome. The doctor should be informed in advance about all medications taken regularly.

Alcohol enhances the vasodilatory effect and the risk of orthostatic hypotension, and in combination with dapoxetine, it increases the likelihood of dizziness and fainting — therefore, it is better to exclude strong drinks during therapy. A minimal amount of low-alcohol beverages is considered acceptable, but even it can reduce the effectiveness of treatment. Due to possible visual impairment and dizziness in the first hours after administration, one should refrain from driving vehicles and operating machinery. The body's reaction is individual, so personal tolerability should be assessed in safe conditions.

Where to buy Centurion Laboratories in Ukraine

The manufacturer's products are presented in specialized online pharmacies and online stores working with Indian generics, with delivery by postal services throughout the country. When ordering, you should pay attention to the integrity of the blister, the presence of the batch number, manufacturing and expiration dates, as well as the manufacturer's holographic marking. Tablets should be stored in their original packaging at temperatures up to 25 °C, in a dry place, protected from light and out of reach of children.

It should be remembered that drugs of this group belong to prescription-only medicines, and they should be prescribed by a doctor after assessing the state of the cardiovascular system, pressure indicators, and the list of concomitant medications. Self-treatment for erectile dysfunction is dangerous because it masks the real cause — vascular pathology, diabetes, or hormonal disorders that require separate therapy. Individual sensitivity to active substances varies significantly, so the optimal drug and dose are selected personally. Consultation with a urologist or andrologist before the first intake remains a mandatory condition for safe treatment.
