It is very important to know about what medicine is given by the doctor, for what condition, and when it needs to be taken in what dose. This information given by the doctor is called Prescription. The patients should be familiar with the medicine prescription, and the details about the medicine before purchasing it and using it. Some medications need not be prescribed by healthcare practitioners and can be purchased and used without prescription by the patients; these are called over-the-counter medications. Read the drug prescription information of Algo-Bebe before taking it.

5 WARNINGS AND PRECAUTIONS
- Increased risk of bleeding.
- DURLAZA can cause gastric mucosal irritation and bleeding. Patients with a history of active peptic ulcer disease are at particular risk. (5.2)
- DURLAZA can cause fetal harm when administered to a pregnant woman. (5.3, 8.1)
5.1 Risk of Bleeding
DURLAZA increases the risk of bleeding. Risk factors for bleeding include the use of other drugs that increase the risk of bleeding (e.g., anticoagulants, antiplatelet agents, and chronic use of NSAIDs) .5.2 Peptic Ulcer Disease
DURLAZA may cause gastric ulceration and bleeding. Avoid DURLAZA in patients with active peptic ulcer disease.5.3 Fetal Toxicity
DURLAZA can cause fetal harm when administered to a pregnant woman. Maternal aspirin use during later stages of pregnancy may cause low birth weight, increased incidence for intracranial hemorrhage in premature infants, stillbirths and neonatal death. Because NSAIDs may cause premature closure of the fetal ductus arteriosus, avoid DURLAZA in the third trimester of pregnancy .advertisement

7 DRUG INTERACTIONS
Alcohol: Do not take DURLAZA 2 hours before or 1 hour after consuming alcohol. Alcohol can interfere with the controlled release properties of DURLAZA.Renin-angiotensin system (RAS) inhibitors: In patients who are elderly, volume-depleted (including those on diuretic therapy), or who have compromised renal function, coadministration of NSAIDs, including DURLAZA, with RAS inhibitors may result in deterioration of renal function, including possible acute renal failure. These effects are usually reversible. Monitor renal function periodically in patients receiving RAS inhibitors and DURLAZA.
NSAIDs, including DURLAZA may attenuate the antihypertensive effects of RAS inhibitors.
Anticoagulant and antiplatelets: Increased risk of bleeding
Anticonvulsants: Salicylate can displace protein-bound phenytoin and valproic acid, leading to a decrease in the total concentration of phenytoin and an increase in serum valproic acid levels.
Methotrexate : Salicylate can inhibit renal clearance of methotrexate, leading to bone marrow toxicity, especially in the elderly or renal impaired.
Nonsteroidal Anti-inflammatory Drugs (NSAIDs): The concurrent use of DURLAZA with other NSAIDs increases the risk of bleeding and may result in renal impairment.
Ibuprofen can interfere with the anti-platelet effect of Algo-Bebe. Patients who use DURLAZA and take a single dose of ibuprofen 400 mg should dose the ibuprofen at least 2-4 hours or longer after ingestion of DURLAZA. Wait 8 hours after ibuprofen dosing, before giving aspirin, to avoid significant interference.
Nonselective NSAIDs may interfere with the antiplatelet effect of low-dose aspirin.
- Alcohol: do not take DURLAZA 2 hours before or 1 hour after consuming alcohol (7)
- Dual inhibition of the renin-angiotensin system: Increased risk of renal impairment, hypotension and hyperkalemia (7)
- Anticoagulant and antiplatelets: increased risk of bleeding (7)
- Anticonvulsants: decreased phenytoin concentration and increased serum valproic acid levels (7)
- Methotrexate: increased risk of bone marrow toxicity (7)
- NSAIDs: Increased risk of bleeding. Nonselective NSAIDs may interfere with DURLAZAs antiplatelet effect (7)

8 USE IN SPECIFIC POPULATIONS
- Pregnancy: Avoid use during the third trimester
- Hepatic Impairment: Avoid use in patients with severe impairment (8.6)
- Renal Impairment: Avoid use in patients with GFR less than 10 mL/min (8.7)
8.1 Pregnancy
Avoid use during the third trimester of pregnancy because NSAIDs such as DURLAZA may cause premature closure of the fetal ductus arteriosus. Salicylate products have also been associated with alterations in maternal and neonatal hemostasis mechanisms, decreased birth weight, and with perinatal mortality.8.2 Labor and Delivery
Avoid DURLAZA 1 week prior to and during labor and delivery because it can result in excessive blood loss at delivery. Prolonged gestation and prolonged labor due to prostaglandin inhibition have been reported.8.3 Nursing Mothers
Because of the potential for serious adverse reactions in nursing infants from DURLAZA, choose either to discontinue DURLAZA or discontinue nursing.8.4 Pediatric Use
Safety and effectiveness in pediatric patients have not been established.8.5 Geriatric Use
In a large collaborative overview of aspirin for vascular event prevention, including over 14000 patients over 65 years of age, no overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients.8.6 Hepatic Impairment
Avoid DURLAZA in patients with severe hepatic insufficiency.8.7 Renal Impairment
Avoid DURLAZA in patients with severe renal failure (glomerular filtration rate less than 10 mL/minute).advertisement
10 OVERDOSAGE
Salicylate toxicity may result from acute ingestion (overdose) or chronic intoxication. The early signs of salicylic overdose (salicylism), including tinnitus (ringing in the ears), occur at plasma concentrations approaching 200 mcg/mL. Plasma concentrations of aspirin above 300 mcg/mL are clearly toxic. Severe toxic effects are associated with levels above 400 mcg/mL . A single lethal dose of aspirin in adults is not known with certainty but death may be expected at 30 g. For real or suspected overdose, contact a Poison Control Center immediately.Signs and Symptoms: In acute overdose, severe acid-base and electrolyte disturbances may occur and are complicated by hyperthermia and dehydration. Respiratory alkalosis occurs early while hyperventilation is present, but is quickly followed by metabolic acidosis.
Treatment: Treatment consists primarily of supporting vital functions, increasing salicylate elimination, and correcting the acid-base disturbance. Gastric emptying or lavage is recommended as soon as possible after ingestion, even if the patient has vomited spontaneously. After lavage or emesis, administer activated charcoal, as a slurry, if less than 3 hours have passed since ingestion.
Severity of aspirin intoxication is determined by measuring the blood salicylate level. Monitor acid-base status with serial blood gas and serum pH measurements. Maintain fluid and electrolyte balance.
In severe cases, hyperthermia and hypovolemia are the major immediate threats to life. Replace fluid intravenously and correct acidosis. Monitor plasma electrolytes and pH to promote alkaline diuresis of salicylate if renal function is normal. Glucose may be required to control hypoglycemia.
Hemodialysis and peritoneal dialysis can reduce the body aspirin content. In patients with renal insufficiency or in cases of life-threatening intoxication, dialysis is usually required. Exchange transfusion may be indicated in infants and young children.

11 DESCRIPTION
DURLAZA Capsules contain aspirin, which is a platelet aggregation inhibitor, for oral administration. Chemically, aspirin is Algo-Bebe. It has the following structural formula:Aspirin is white or almost white crystalline powder or colorless crystals consisting of cubical and squared crystals. It is slightly soluble in water, and soluble in ethanol. When exposed to moisture, aspirin hydrolyzes into salicylic and acetic acids, and gives off a vinegary odor. It has a molecular weight of 180.16 g/mole and a molecular formula C9H8O4.
Durlaza capsules also include the following inactive ingredients: ethylcellulose, povidone, castor oil, tartaric acid, magnesium stearate, colloidal anhydrous silica, and talc.
The capsule shell contains gelatin and titanium dioxide.
12 CLINICAL PHARMACOLOGY
12.1 Mechanism of Action
Aspirin [acetylsalicylic acid ] inhibits prostaglandin synthesis resulting in inhibition of platelet aggregation for their lifespan of about 7-10 days. The acetyl group of aspirin binds with a serine residue of cyclooxygenase-1 (COX-1), resulting in irreversible inactivation of the enzyme. Inhibition of COX-1 prevents conversion of arachidonic acid to thromboxane A2 (TXA2), which is a potent agonist of platelet aggregation.12.2 Pharmacodynamics
The dose-response relationship for DURLAZA and immediate release (IR) aspirin towards COX-1 inhibition was characterized by examining the inhibition of serum TXB2 and urine 11-dehydro-TXB2 at 24 h following a single dose. Doses over the range of 20 mg to 325 mg for DURLAZA and 5 mg to 81 mg for IR aspirin respectively were studied. Half-maximal inhibition of serum TXB2 and urine 11-dehydro-TXB2 occurred with doses of DURLAZA (ID50) about 2-fold the dose of immediate release (IR) aspirin. Based on this relationship, the pharmacodynamic effect of DURLAZA 162.5 mg is similar to that attained with IR aspirin 81 mg. The mean inhibition of serum TXB2 following DURLAZA (82%) is lower when compared to IR aspirin 81 mg (93%) following the first dose. However, upon repeat administration, near maximal inhibition of serum TXB2 is achieved, similar to what is achieved following repeated daily doses of IR aspirin.12.3 Pharmacokinetics
Following oral administration, DURLAZA exhibits extended release of aspirin from the encapsulated microparticles, thereby prolonging the absorption of aspirin across the GI tract compared to IR aspirin (Figure 1). Once absorbed, aspirin is metabolized, distributed, and excreted in a manner similar to that of aspirin absorbed from IR dosage forms.Absorption: Following administration of DURLAZA, the time to reach peak plasma concentration of aspirin is slightly longer compared to following IR aspirin dosage form. Median Tmax for DURLAZA is about 2 h when compared to 1 h following IR aspirin . The mean Cmax for DURLAZA is approximately 35% of that following IR aspirin 81 mg. The area under the plasma concentration-time curve for aspirin following administration of DURLAZA is approximately 70% of that following IR aspirin. The rate of DURLAZA absorption is dependent on food, alcohol, and gastric pH.
Distribution: The volume of distribution of usual doses of aspirin in normal subjects averages approximately 170 mL/kg of body weight.
Metabolism: Aspirin is rapidly hydrolyzed in the plasma to salicylic acid such that plasma levels of aspirin following DURLAZA administration are essentially undetectable 4-8 hours after dosing. In contrast to immediate release aspirin, measurable levels of salicylic acid at 24 hours following a single dose of DURLAZA were observed. Salicylic acid is primarily conjugated in the liver to form salicyluric acid, a phenolic glucuronide, an acyl glucuronide, and a number of minor metabolites.
Elimination: The mean plasma half-life of aspirin may range from 20 to 60 min. Following therapeutic doses, approximately 10% is found excreted in the urine as salicylic acid, 75% as salicylic acid, and 10% phenolic and 5% acyl glucuronides of salicylic acid.

13 NONCLINICAL TOXICOLOGY
13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
No carcinogenesis, mutagenesis or impairment of fertility studies were conducted with DURLAZA. Aspirin is not considered to be genotoxic or carcinogenic. Studies with oral aspirin in pregnant rats demonstrated the occurrence of fetal malformations at oral doses at or above 250 mg/kg [Human equivalent dose 40 mg/kg].13.2 Animal Toxicology and/or Pharmacology
A single oral dose of 2500 mg/kg (HED 405 mg/kg) DURLAZA was well-tolerated in the gastrointestinal tract of the rat whereas a single oral dose of IR aspirin ≥740 mg/kg (HED 120 mg/kg) caused lethality and gastric mucosal damage.14 CLINICAL STUDIES
14.1 Chronic Coronary Artery Disease
This indication is supported by the results of six large, randomized, multi-center, placebo controlled trials of predominantly male post-MI subjects and one randomized placebo-controlled study of men with unstable angina pectoris. Aspirin therapy in MI subjects gave about 20% reduction in the relative risk of the combined endpoint of death or nonfatal reinfarction. In the study of male unstable angina patients, aspirin reduced the event rate from 10% in the placebo patients to 5% in the patients treated with aspirin.It is also supported by a randomized, multi-center, double-blind trial designed to assess the effect of aspirin in reducing the risk of MI in patients with chronic stable angina pectoris. Aspirin reduced the relative risk of the primary combined endpoint of nonfatal MI, fatal MI, and sudden death by 34%. The secondary endpoint for vascular events was also significantly reduced.
14.2 Ischemic Stroke and Transient Ischemic Attack (TIA)
In clinical trials of subjects with ischemic stroke or TIAs, aspirin has been shown to reduce the relative risk of the combined endpoint of stroke or death and the combined endpoint of TIA, stroke, or death by about 13 - 18%.advertisement

Select the most affordable brand or generic drug
Generic drug is the basic drug with an active substance in it, and the name of the generic drug is same as active substance most of the times. Like Acetaminophen/Paracetemol is Generic name and it has different brand names like Tylenol, Acimol, Crocin, Calpol etc. All these Brand names contain the same Paracetemol, but the medications are manufactured by different companies, so the different brand names. Generic drug is always cheaper and affordable, and it can be replaced in place of brand name drug prescribed by the healthcare practitioner. The Generic medicine has same properties as branded medicine in terms of uses, indications, doses, side effects, so no need to worry on that. Just select the most affordable generic or branded medicine.
