Is it possible to insert papaverine for hemorrhoids?

Hemorrhoids are varicose veins of the rectum. Lumps that form on the veins make it difficult for stool to pass through, causing discomfort and even pain during bowel movements. Thanks to Papaverine, it is possible to achieve relaxation of the intestinal muscles, which greatly facilitates bowel movements. In the initial stages of hemorrhoids, Papaverine is an excellent remedy to prevent the problem from worsening. In addition, the drug is often prescribed for constipation, as suppositories have a laxative effect.

Compound

The composition of Papaverine depends on the form of release of the drug. In all cases, the medicine contains one active component - papaverine hydrochloride. Tablets, injection solution and suppositories include various auxiliary components. The exact information can be found in the table.

Chemical composition of various forms of Papaverine

The pharmacological group of the drug is myotropic antispasmodics, vasodilators.

International nonproprietary name (INN) – Papaverine, Papaverine (English), Papaverinum (Latin).

Why papaverine injections?

In addition to tablets and suppositories, there is also a dosage form in the form of a solution for intravenous or intramuscular administration. This method of delivering medicine to the body is used when there is no time to wait for the drug to be absorbed through the gastrointestinal tract. Among these patients are pregnant women. They may be prescribed Papaverine by drip method. While staying in hospital for preservation, women receive regular doses of Papaverine, and the result can be monitored by an obstetrician in order to promptly make adjustments to therapy if necessary.

Papaverine ointment

Papaverine ointment is a separate medication group. The product contains an active component - papaverine hydrochloride and auxiliary components - purified water, lanolin, sunflower oil.

Indications for use:

• conditions associated with intestinal spasms;
• spastic constipation;
• haemorrhoids;
• anal spasm;
• spasms caused by diseases of the genitourinary system.

Papaverine cream is applied to the perineum and anus to reduce pain. It is recommended to do this after carrying out hygiene procedures 2–3 times a day. If the patient uses other ointments and gels, be sure to inform the doctor about this.

Pharmacological properties

The drug papaverine has a good antispasmodic and moderate analgesic effect. Due to its ability to relieve spasm from the smooth muscles of internal organs and blood vessels, the medicine has a mild hypotensive effect. This makes it possible to use it in the initial stages of hypertension and in some other conditions characterized by increased blood pressure.

Once in the body, the active component papaverine hydrochloride inhibits the activity of phosphodiesterase enzymes, which leads to a decrease in calcium concentration in cells. This process contributes to disruption of the contractile function of smooth muscles, consequently, muscle relaxation, elimination of spasm and pain.

The medicine Papaverine is used for diseases of the respiratory, digestive, cardiovascular systems, and for diseases of the kidneys, liver, gall bladder and other organs.

Important! Despite Papaverine’s ability to relax the smooth muscles of the muscles, a person’s motor activity is completely preserved.

Composition and mechanism of action

Each ampoule (2 ml) contains a 2% injection solution containing papaverine hydrochloride (20 mg/1 ml), with the addition of the following ingredients: D, L-methionine, disodium edetate, water for injection.

Papaverine in ampoules is packaged in cardboard packages in quantities of 5 and 10 pieces.

Treatment with Papaverine helps to relax smooth muscles in organs and blood vessels, reduce their tone, dilate arteries, which improves blood flow, including cerebral, and leads to a decrease in blood pressure.

The injection solution has a relaxing, but not paralyzing, effect with complete preservation of muscle movements.

The drug inhibits the enzyme phosphodiesterase (PDE), resulting in the accumulation of cyclic mononucleotides (cAMP) in cells. As a result of this process, calcium ions leave the cells and the contractile activity of muscle fibers decreases.

Injections of the drug in large dosages help slow intracardiac conduction and reduce the excitability of the heart muscle. This property of the drug gives it a sedative effect.

The therapeutic effect of the drug when administered intramuscularly occurs after approximately 20 minutes. after injection and lasts about 5 hours. Papaverine is excreted through the kidneys.

Pharmacokinetics

The active substance, entering the body, is quickly absorbed, regardless of the form of release of the drug. Communication with blood proteins is up to 90%. The drug is metabolized in the liver. The approximate half-life of Papaverine ranges from half an hour to 120 minutes. Active and auxiliary components are excreted from the body by the kidneys in the form of metabolites.

The effect of the medicine is observed after 15 – 20 minutes

When to use the product

What is Papaverine used for? The medicine is used orally, rectally, intravenously or intramuscularly for various diseases that cause spasm of the smooth muscles of the body.

Indications for use of Papaverine are as follows:

• diseases of the abdominal organs (cholecystitis, spastic colitis, pancreatitis, etc.);
• as a complex treatment for relieving hypertensive crisis;
• violation of urine discharge from the kidneys;
• spasms of peripheral veins;
• conditions associated with contraction of cerebral vessels;
• to relieve angina attacks;
• respiratory dysfunction;
• narrowing of the renal arteries;
• narrowing of the urinary tract caused by spasm, causing urinary retention.

Papaverine should be taken strictly according to a doctor’s prescription, despite its wide spectrum of action and apparent safety. Improper use of the drug often provokes many side effects.

Indications

The medicine can be used as an independent remedy or along with other medications and helps get rid of:

• spasms of smooth muscles (most often with spastic colitis, cholecystitis, pylorospasm);
• serious condition due to excessive increase in blood pressure;
• endarteritis and other spasms of peripheral vessels;
• acute pain syndrome in the kidneys due to impaired urine outflow due to impaired patency of the upper urinary tract;
• bronchospasms;
• angina pectoris;
• spasms of blood vessels in the brain;
• difficulty in urinating or its absence due to spasms in the urinary tract;
• hemorrhoids, large hemorrhoids (in this case it is advisable to resort to rectal suppositories);
• high temperature;
• impotence.

Often, relaxation of smooth muscles before urological or proctological operations, as well as manipulations in the abdominal cavity, is achieved using Papaverine injections

To whom the product is prohibited

Instructions for use of Papaverine include absolute and relative contraindications to the use of the medicine.

Absolute:

• individual sensitivity of the patient to the active and auxiliary substances of the drug;
• heart diseases associated with its conduction (blockades);
• acute kidney pathologies, renal failure;
• liver pathologies;
• glaucoma;
• age of patients after 65 years, which is associated with an increased risk of developing hypertension);
• children's age: injections/tablets/suppositories – 6 months/14 years/18 years.

When prescribing a drug, its contraindications must be taken into account.

Relative:

• recent traumatic brain injury;
• chronic renal failure;
• anaphylactic shock;
• vascular collapse;
• dysfunction of the adrenal cortex.

Important! The decision on the advisability of prescribing a drug in the presence of relative contraindications is made by the leading specialist, assessing the balance of benefit and risk in a particular case.

Contraindications

The drug is not used in the following cases:

• in case of individual intolerance or hypersensitivity to the ingredients of the drug;
• disruption of the transmission of nerve impulses in the conduction system of the heart (atrioventricular block);
• severe liver failure;
• glaucoma;
• comatose states;
• depressed breathing;
• bronchial obstruction;
• low blood pressure.

Papaverine is not used in childhood until the child is one year old and in elderly people due to the risk of increased body temperature

The use of the drug is possible only under the supervision of an experienced specialist due to the following reasons:

• recent intracranial injuries;
• chronic pathological changes in the kidneys;
• lack of thyroid hormones (thyroid hormones) in the body;
• shock;
• an increase in the number of benign pancreatic cells;
• arrhythmia caused by disruption of electrical conductivity and regulation of heart rate;
• adrenal insufficiency.

In addition, the use of papaverine in combination with monoamine oxidase inhibitors is prohibited.

Side effects

Papaverine in tablets, injections and when using rectal suppositories can cause side effects. More often this is due to non-compliance with the dosage prescribed by the doctor or self-medication with the drug.

Undesirable consequences:

• pathological decrease in blood pressure;
• heart blocks;
• increased sweating;
• nausea;
• constipation;
• yellow tint to the dermis and eyeballs;
• irritability, drowsiness;
• fatigue, loss of ability to work;
• when using the drug intravenously, vein thrombosis is possible;
• blood composition disorder;
• allergic skin rashes.

If the described symptoms appear, you must immediately stop taking the medication and seek medical help. Treatment is usually carried out by normalizing blood pressure and removing excess drugs from the body.

Arterial pressure

The combination of dibazole with papaverine normalizes blood pressure and eliminates the unpleasant symptoms of its increase.

The combined use of two drugs has a better medicinal effect than each drug separately, due to the ability to enhance the therapeutic effect of each other

The dosage should be calculated by the doctor depending on the general condition of the patient, as well as his blood and pulse pressure. As a rule, Papaverine 2 ml and Dibazol 4 ml are used.

In case of critical condition of the patient, Analgin is added to the above drugs to enhance the analgesic effect.

At the moment, there is a combined dosage form of Papaverine and Dibazol - Papazol. This drug is available in tablets and has vasodilating and antispasmodic effects.

Today, the pharmaceutical industry offers numerous medications for high blood pressure. But Dibazol and Papaverine do not lose their popularity due to their relative safety, good effectiveness and rare occurrence of side effects.

The drugs are administered intramuscularly and:

• eliminate vascular spasms in the brain;
• dilate blood vessels;
• relieve pain associated with high blood pressure and normalize its levels;
• minimize the risk of hypertensive crisis.

A universal remedy for lowering blood pressure is triad containing:

• analgin (50% solution, 2 ml);
• papaverine (2% solution, 2 ml);
• diphenhydramine (1% solution, 1 ml).

Triad injections also have an antipyretic effect, but in any case their use must be approved by the attending physician.

Directions for use and doses

Let's look at how to take Papaverine. For children and adults, the dosage is selected individually depending on the characteristics of the course of the disease.

The dosage and regimen are selected exclusively by the doctor.

The dosage of tablets for an adult is usually 40 – 60 mg. Papaverine is prescribed to children in accordance with the characteristics of the disease, age and weight of the patient.

Suppositories are prescribed in 1 - 3 pieces (20 - 60 mg) for adult patients. Until the age of 14, the drug is used with extreme caution only if necessary.

Papaverine solution is administered intravenously very slowly, exclusively by a medical professional. The contents of one ampoule are diluted with 20 ml of sodium chloride. Intramuscular injections of Papaverine are prescribed to patients at 40–60 mg per day.

Dosage

The excellent bioavailability of the drug allows the use of intramuscular, subcutaneous or intravenous injections without loss of its therapeutic abilities.

To avoid hematomas, a subcutaneous injection is given on the outer thighs or in the shoulder. An intramuscular injection is given in the outer upper quadrant of the buttock

Treatment with papaverine can continue for a long time, as prescribed by the attending physician, and is completed as the painful condition is eliminated.

Before administering a pharmaceutical drug intravenously, it is diluted with saline solution (NaCl) in an amount of 10–20 ml. To avoid discomfort in the patient, papaverine is administered slowly.

Intramuscular and intravenous injections involve the use of the following dosages:

• for the adult category of the population – one-time – 0.1 g, per day – 0.3 g;
• from six months to a year - one-time - 0.005 g, per day - 0.01 g;
• 2–3 years – one-time – 0.01 g, per day – 0.02 g;
• from 3 to 4 years – one-time – 0.015 g, per day – 0.03 g;
• from 5 to 6 years – one-time – 0.02 g, per day – 0.04 g;
• from 7 to 9 years – one-time – 0.03 g, per day – 0.06 g;
• from 10 to 14 years – one-time – 0.06 g, per day – 0.1–0.2 g.

It should be taken into account that the interval between intravenous injections should be at least 4 hours.

When administered subcutaneously, the dosage of the drug is usually 1 ampoule.

An overdose of the drug can lead to general malaise, diplopia, increased sweating, headaches and arrhythmia.

These symptoms can be eliminated with symptomatic therapy and gastric lavage.

Use during pregnancy

Despite the fact that one of the contraindications of Papaverine is the period of pregnancy and lactation, the drug is still prescribed to women bearing a child.

Many mothers face such a problem as increasing the tone of the uterus. This condition brings a lot of unpleasant sensations, in addition, it poses a threat of premature birth. To relax the muscles of the reproductive organ, Papaverine tablets or suppositories are often used. In a hospital setting, injections can be used.

Papaverine is used to prepare the cervix before childbirth. The drug is used in combination with No-Spa and other agents. Throughout the day, the woman is administered one suppository of each drug.

When breastfeeding, the use of Papaverine is contraindicated, since the active component of the drug passes into the mother's milk and therefore reaches the baby. If there is a need to use medication, stop feeding the baby.

Is it possible to drink papaverine during menstruation?

Periodic female pain associated with menstruation occurs due to contractions of the uterine muscles. This is how the organ gets rid of the overgrown endometrium, which was lined throughout the entire cycle, awaiting the attachment of the fertilized egg. Due to the absence of a fertilized egg, at the beginning of the cycle the level of hormones in the body changes, which causes emptying of the uterine cavity. For better rejection, the organ contracts, which causes severe pain in women. Papaverine, acting on smooth muscles, relieves pain and dilates blood vessels, which facilitates the release of blood clots. Papaverine is taken during menstruation according to two different schemes:

• if menstruation is always painful, you are allowed to take 1 tablet three times a day during the first three days of the cycle.
• If menstruation is usually painless, with occasional cramps, there is no need to take the drug as a course, a single dose is enough to stop the attack. If necessary, the dose can be repeated, but not earlier than 4 hours after the first use.

special instructions

During therapy with the medication, you should avoid drinking alcohol. The active components of the product in combination with alcohol can cause a negative reaction.

Papaverine often has positive reviews, but despite this, the medicine should be used only as prescribed by a doctor.

The drug of any release form is used with extreme caution among patients with severe pathologies of the kidneys and liver.

Alcoholic beverages should be avoided during treatment with Papaverine.

When administered intravenously, the injection is given slowly and under the supervision of a doctor. Too rapid administration can cause heart rhythm disturbances and other negative consequences.

Among patients who have suffered skull injuries, the medicine is used only if necessary in a hospital setting.

pharmachologic effect

Papaverine hydrochloride is a myotropic antispasmodic agent.

It is an inhibitor of the phosphodiesterase enzyme and causes intracellular accumulation of cyclic 3′,5′-adenosine monophosphate and a decrease in calcium content, which leads to impaired contractility of smooth muscles and their relaxation.

The effect of papaverine hydrochloride on the central nervous system is weak, only in large doses it has a sedative effect.

Reduces the tone of smooth muscles of internal organs (gastrointestinal tract, airways, genitourinary system) and blood vessels and therefore has a vasodilator and antispasmodic effect. In large doses, it reduces the excitability of the heart muscle and slows down intracardiac conduction.

Indications for use

Spasm of smooth muscles: abdominal organs (with cholecystitis, pylorospasm, spastic colitis, attacks of cholelithiasis), renal colic, spasm of the urinary tract; peripheral vessels (with endarteritis); cerebral vessels (for migraines); heart (for angina) – as part of complex therapy); bronchi (with bronchospasm).

Patient reviews

Valery, Taganrog “Papaverine is always in our medicine cabinet. Of course, my wife and I don’t take pills constantly and uncontrollably, but in some cases they really do help, especially since we both suffer from periodic high blood pressure. The drug is good, it’s inexpensive, I’m satisfied with its effect.”

Natalya, Kazan “When the weather changes, I always suffer from headaches. This is due to vasospasm. The doctor recommended that I take a Papaverine tablet. The product helps well, after 15-20 minutes I feel relief.”

Victor, Ivanovo “Several years ago I was diagnosed with urolithiasis. I was in the hospital where they crushed stones for me. Now fine sand is still coming out little by little. In this case, the pain is quite severe. To alleviate the condition, the doctor prescribed me Papaverine. The drug does its job perfectly, the pain goes away within a quarter of an hour.”

Reviews

Svetlana, 25 years old, Murmansk, young mother The pregnancy was long-awaited, but it was difficult. The uterus was constantly in good shape, suffered from severe swelling and increased blood pressure. She was constantly in the hospital due to the threat of a breakdown. Doctors prescribed papaverine along with other medications. The drug was injected 4 times a day. My health improved almost immediately. She gave birth to a healthy child.

Elena Gennadievna, 65 years old, Belgorod, pensioner High blood pressure is a problem that has haunted me for several decades. I have a small pension, so many effective medicines on the shelves of pharmacies remain inaccessible to me. The attending physician prescribed triad injections and explained how much of each component the ampoules contained and what they were intended for. The composition turned out to be very effective, it relieves pressure very quickly. Plus, all the ingredients are cheap and don't cause me any side effects.

Svetlana, 32 years old, Rostov, engineer The few days before the start of menstruation were real hell for me. Cramping pain in the lower abdomen did not allow me to live normally. Often I had to get sick leaves or certificates from the clinic, since work was out of the question. My mother advised me to take papaverine injections, arguing that it would relieve pain and would not cause harm. I still use her advice to this day. Injections two days before my period provide me with a full life.
