Buy Generic Cialis online without prescription

Cialis is an effective drug for the treatment of male erectile dysfunction, commonly known as impotence. Its active ingredient, tadalafil, works by improving blood flow to the penis during sexual stimulation, helping to achieve and maintain a satisfactory erection. Unlike other similar drugs, Cialis is notable for its prolonged duration of action, which can be extended up to 36 hours, allowing for greater spontaneity in sexual intercourse. Available in 5mg, 10mg and 20mg doses, this drug offers the possibility to tailor treatment to the specific needs of each patient. In addition to the original version, there is a cheaper generic alternative with identical efficacy and safety.

History and development of Cialis

Cialis was developed by the pharmaceutical company Eli Lilly and Company, which began research on tadalafil in the mid-1990s. After years of clinical studies, the drug received approval from the US Food and Drug Administration (FDA) in November 2003, and shortly afterwards it was authorised by the European Medicines Agency (EMA) to be marketed in Europe, including Spain.

Initially, Cialis was developed exclusively for the treatment of erectile dysfunction, but later, in 2011, it also received approval to treat the symptoms of benign prostatic hyperplasia (BPH), making it the first drug approved for both conditions simultaneously. This therapeutic versatility greatly expanded its clinical use and benefited many patients with both conditions.

How Cialis works

Cialis works by a specific mechanism that enhances the body's natural response during sexual arousal. When a man experiences sexual stimulation, the body releases nitric oxide into the tissues of the penis, which activates an enzyme called guanylate cyclase. This enzyme increases levels of cyclic guanosine monophosphate (cGMP), a substance that relaxes the smooth muscles of the corpora cavernosa and increases blood flow to the penis.

Tadalafil, the active ingredient in Cialis, works as a selective inhibitor of phosphodiesterase type 5 (PDE5), the enzyme that breaks down cGMP. By blocking this enzyme, Cialis allows cGMP levels to remain elevated for longer, maintaining vasodilation and promoting a longer-lasting erection. This process makes it easier for blood to flow into the penis and harder for it to flow out, creating the conditions necessary to achieve and maintain a firm erection.

It is important to note that Cialis does not produce an automatic erection, but optimises the physiological response to sexual stimulation. Without prior arousal, the drug will have no effect, as it requires the natural release of nitric oxide to initiate the biochemical cascade that culminates in erection. In addition, its effectiveness may be reduced in the presence of severe nerve damage, severe vascular disturbances or significant hormonal imbalances.

Who should take Cialis?

Cialis is primarily indicated for adult men who experience consistent difficulty in achieving or maintaining a satisfactory erection during sexual activity. This condition, known medically as erectile dysfunction, can manifest in varying degrees of severity and can affect men of any age, although it is most common in men over 40.

The profile of patients who may benefit from treatment with Cialis includes:

• Men with erectile dysfunction of psychogenic origin (stress, anxiety, depression)
• Patients with organic causes of erectile dysfunction (diabetes, hypertension, cardiovascular problems)
• Men who have experienced erectile dysfunction after pelvic surgeries
• Patients with symptoms of benign prostatic hyperplasia (difficulty in urinating)
• People looking for a treatment with a prolonged effect that allows for more spontaneity

It is important to note that Cialis is contraindicated in children under the age of 18 and should be used with caution in adults over the age of 65, who may require dosage adjustments. It should also be avoided in patients with certain serious heart conditions, such as unstable angina, severe heart failure, or a recent history of heart attack or stroke.

The entire procedure respects the security and data protection standards set by European legislation.

What is generic Cialis?

Generic Cialis is a bioequivalent version of the original drug containing the same active ingredient, tadalafil, in identical dosage and dosage forms. The main difference is that generics are produced by laboratories other than the original manufacturer (Eli Lilly), once the patent on the drug has expired, allowing them to be marketed at considerably lower prices.

It is essential to understand that generic medicines must meet the same standards of quality, safety and efficacy as the originals, being subjected to rigorous controls by the health authorities before being authorised for sale. Bioequivalence guarantees that the generic has the same pharmacokinetic behaviour as the brand-name medicine, ensuring identical therapeutic results.

Among the main manufacturers of generic Cialis available on the Spanish market are renowned pharmaceutical laboratories such as Teva, Mylan, Normon, Cinfa and Sandoz. These laboratories have extensive experience in the production of high quality generic medicines and comply with the Good Manufacturing Practice (GMP) standards established by the European Union.

The most notable advantage of generic Cialis is its affordability, with prices that can be up to 70% lower than the brand name drug, without compromising its effectiveness or safety. This cost reduction has allowed many patients to maintain ongoing treatments that were previously prohibitively expensive due to the high price of the originator drug.

What is the price of Cialis in Spain?

The price of Cialis in Spain varies considerably depending on several factors, mainly whether it is the original drug or its generic version, the dosage selected and the number of tablets per pack. Additionally, there may be differences between physical and online pharmacies, as well as temporary promotions that affect the final cost.

Below is a table comparing approximate prices for both the original Cialis and its generic version with tadalafil, based on average prices in the Spanish market:

As can be seen in the table, the savings by opting for the generic version are substantial and can exceed 60% compared to the price of the original medicine. In addition, our online pharmacy regularly offers additional discounts for larger orders and loyalty programmes to further reduce the cost of treatment in the long term.

How to take Cialis

Correct administration of Cialis is essential to maximise its effectiveness and minimise potential side effects. There are two main approaches to taking Cialis: as needed (on-demand) and daily dosing. The choice between these regimens will depend on personal preference, frequency of sexual activity and the recommendations of the healthcare professional.

For on-demand (occasional) use:

1. Take one tablet of Cialis (usually 10mg as a starting dose, adjustable to 5mg or 20mg depending on response) at least 30 minutes before planned sexual activity.
2. Take the whole tablet with a glass of water, regardless of meals.
3. Do not take more than one dose in 24 hours.
4. Remember that the effect can last up to 36 hours, so it is not necessary to time your intake exactly with sexual activity.

For the daily dosage regimen:

1. Take one low-dose tablet (usually 2.5mg or 5mg) once a day at about the same time.
2. Maintain this routine no matter when you plan to have sex.
3. This approach allows constant blood levels of the drug to be maintained, enabling spontaneity in relationships.

It is important to avoid consuming large amounts of alcohol during treatment with Cialis, as it may increase the risk of side effects such as dizziness and low blood pressure. The consumption of grapefruit or grapefruit juice should also be avoided, as it can interfere with the metabolism of the drug, potentially increasing its concentration in the blood.

Dosage: how to take Cialis for the first time

Initiating treatment with Cialis requires special attention to determine the most appropriate dosage to provide the desired effect with minimal side effects. Available presentations include 2.5mg, 5mg, 10mg and 20mg tablets, each intended for different needs and treatment regimens.

For first-time users of Cialis, the general recommendations are:

• Initial dose for occasional use: 10mg taken before sexual activity. This dose has been shown to be effective in approximately 70% of patients during clinical trials.
• Initial dose for daily use: 2.5mg once daily, may be increased to 5mg depending on tolerance and efficacy.
• Subsequent adjustments: Depending on individual response, the dose for occasional use may be reduced to 5mg if side effects are experienced, or increased to 20mg if response is insufficient.

Factors that may influence the selection of the starting dose include age (those over 65 years of age usually start with lower doses), renal and hepatic function, and concomitant intake of other medications. Patients with moderate renal impairment should not exceed 10mg per dose, while those with hepatic impairment should first consult a specialist.

The process of dose optimisation is individual and may require several attempts. It is recommended to keep a record of the efficacy and possible side effects experienced with each dose, so that these can be discussed with your health care professional and adjustments can be made as necessary. The ideal dosage is one that provides a satisfactory erection with minimal discomfort.

How quickly does Cialis take effect?

Cialis stands out among erectile dysfunction medications because of its relatively rapid onset of action combined with its prolonged duration of effect. The speed at which results are seen can vary between individuals, but generally follows a predictable time pattern based on the pharmacokinetic properties of tadalafil.

In most men, Cialis begins to work within 30 minutes to 2 hours after ingestion. Approximately 30% of patients report a satisfactory response within 30 minutes, while this percentage increases to 70-80% within 2 hours of taking the drug. The maximum blood concentration of the drug (peak plasma) is generally reached 2-4 hours after administration, at which time maximum efficacy is usually observed.

Several factors can influence the speed of drug action:

• Food: A high-fat meal may delay the absorption and thus the onset of action of tadalafil.
• Age: In older people, slower metabolism may slightly delay the effect.
• Liver function: Patients with hepatic impairment may experience a delayed onset of action.
• Concomitant medication: Some drugs can interact with Cialis, speeding up or delaying its effect.

To optimise the speed of action, it is recommended to take Cialis on an empty stomach or after a light meal, avoiding large or very fatty meals. In addition, planning your intake well in advance of your planned sexual activity allows you to take advantage of the drug's time of maximum effectiveness.

How long does the effect of Cialis last?

One of the most distinctive features of Cialis compared to other erectile dysfunction drugs is its long duration of action, which is why it has gained popularity among many patients seeking more spontaneity in their sex life. The effect of Cialis can extend significantly beyond that of other similar treatments available on the market.

Under normal conditions, the therapeutic effect of Cialis can remain active for up to 36 hours after administration, which has led to it being colloquially known as the "weekend pill". This extended therapeutic window allows the patient to respond satisfactorily to sexual stimulation for an extended period of time, without the need to strictly synchronise taking the drug with planned sexual activity.

Pharmacokinetically, tadalafil has an elimination half-life of approximately 17.5 hours in healthy adults, significantly longer than other drugs in its class. This means that 17.5 hours after reaching peak blood concentration, approximately 50% of the active substance still remains in the body, maintaining sufficient levels to facilitate erection upon appropriate sexual stimulation.

It is important to clarify that the 36-hour duration does not imply a continuous erection during that period, which would be pathological, but rather the ability to respond with an erection to sexual stimulation within that time window. The intensity of the effect tends to decrease gradually as plasma levels of the drug fall, generally being more potent in the first 24 hours and progressively decreasing thereafter.

Interaction with other medicines

Cialis may interact with various drugs, enhancing their effects or increasing the risk of adverse effects. These interactions may be particularly relevant in patients with multiple medications or cardiovascular conditions. It is essential to inform your doctor about all medications you are taking, including over-the-counter drugs, supplements and herbal products.

The most important interactions to be aware of include:

• Nitrates (absolutely contraindicated): Combining Cialis with nitrates such as nitroglycerin, isosorbide or angina medications can cause a dangerous drop in blood pressure. This interaction is strictly contraindicated and can be life-threatening.
• Alphablockers: Medications such as doxazosin or tamsulosin, used for high blood pressure or prostate problems, may increase the blood pressure lowering effect when combined with Cialis, causing dizziness or fainting.
• Antihypertensives: May potentiate the effect of blood pressure medications, requiring dose adjustments or additional monitoring.
• CYP3A4 inhibitors: Drugs such as ketoconazole, itraconazole, ritonavir or clarithromycin may significantly increase tadalafil blood levels, increasing the risk of adverse effects.
• CYP3A4 inducers: Medicines such as rifampicin, carbamazepine, phenytoin or phenobarbital may reduce the effectiveness of Cialis by lowering blood levels.

In addition to these main interactions, special caution should be exercised with:

• Other treatments for erectile dysfunction: It is not recommended to combine Cialis with sildenafil, vardenafil or other PDE5 inhibitors.
• Riociguat: The combination with this medicine for pulmonary hypertension is contraindicated because of the risk of severe hypotension.
• Anticoagulants and antiplatelet agents: May slightly potentiate the effect of these medicines.

If there is any doubt about possible interactions, especially in patients with chronic or multiple medication regimens, it is recommended to consult a healthcare professional before starting treatment with Cialis.

Cialis with food and alcohol

The relationship between Cialis, food and alcohol consumption is an important aspect to consider in order to optimise the effectiveness of the treatment and minimise possible adverse effects. Unlike other similar medicines, Cialis has some particularities regarding its interaction with food and alcoholic beverages.

Cialis and food:

The absorption of tadalafil is less affected by food intake compared to other medicines in its class. This means that Cialis can be taken with or without food without significantly compromising its effectiveness. However, certain considerations should be taken into account:

• A very large or high-fat meal may slightly delay the onset of action of the medicinal product, without affecting the total amount absorbed.
• For the fastest possible effect, it may be beneficial to take Cialis on an empty stomach or after a light meal.
• Grapefruit or grapefruit juice should be avoided during treatment, as grapefruit contains compounds that can interfere with the enzymes that metabolise tadalafil, potentially increasing blood levels and the risk of side effects.

Cialis and alcohol:

Moderate alcohol consumption is not contraindicated during treatment with Cialis, although some precautions should be kept in mind:

• Both alcohol and Cialis can cause vasodilation and lower blood pressure, so their combination can enhance these effects, causing dizziness, tachycardia or hypotension.
• Small amounts, equivalent to 1-2 glasses of wine or beer, are generally considered safe.
• Excessive alcohol consumption (more than 5 units) should be avoided for several reasons: it may increase the risk of side effects, decrease sexual responsiveness and potentially counteract the beneficial effects of the drug.
• Alcohol itself can be a cause of temporary erectile dysfunction, so excessive consumption of alcohol could neutralise the effectiveness of Cialis.

The general recommendation is to maintain a moderate alcohol intake (no more than 2-3 units) when taking Cialis, paying attention to possible symptoms such as dizziness or tachycardia, which would indicate the need to reduce or completely avoid the consumption of alcoholic beverages during treatment.

Side effects

Like any medicine, Cialis can cause side effects, although not all people experience them and most are mild or moderate and transient in nature. It is important to be aware of them in order to identify them properly and know when it is necessary to seek medical attention.

The most common side effects (may affect between 1 and 10 out of 100 patients) include:

• Headache: Generally mild to moderate in intensity, usually resolves spontaneously
• Dyspepsia or indigestion: Feeling of gastric discomfort or heartburn
• Back pain: Usually appears 12 to 24 hours after intake
• Muscle pain: Especially in extremities, transient in nature
• Nasal congestion: Sensation of obstruction or rhinorrhoea
• Facial blush: Reddening of the face or neck due to vasodilatation
• Dizziness: Especially when getting up quickly

Rare side effects (may affect 1 to 10 out of 1000 patients):

• Blurred vision or changes in colour perception: Temporary visual disturbances
• Eyelid swelling: Mild eyelid oedema
• Palpitations: Sensation of a rapid or intense heartbeat
• Tachycardia: Increased heart rate
• Hypotension: Decrease in blood pressure

It is important to seek immediate medical attention if you experience any of the following rare but serious side effects:

• Prolonged and painful erection (priapism): Erection lasting more than 4 hours requires urgent attention to avoid permanent damage.
• Sudden loss of vision: May indicate non-arteritic anterior ischaemic optic neuropathy (NAION).
• Sudden decrease or loss of hearing: Occasionally accompanied by tinnitus or dizziness.
• Severe allergic reactions: Manifested as rash, itching, facial swelling or difficulty breathing.
• Chest pain: Especially if it occurs during or after sexual activity.

Most mild side effects disappear spontaneously within a few hours or days. If they persist or are bothersome, consult your doctor about possible dosage adjustments. Remember that these effects are usually more frequent at the beginning of treatment and tend to decrease with continued use as the body adapts to the medicine.
