How Heflacure Spas works

Through COX-2 inhibition, aceclofenac downregulates the production of various inflammatory mediators including prostaglandin E2 (PGE2), IL-1β, and TNF from the arachidonic acid (AA) pathway. Inhibition of IL-6 is thought to be mediated by diclofenac converted from aceclofenac . Suppressed action of inflammatory cytokines decreases the production of reactive oxygen species. Aceclofenac is shown to decreased production of nitrous oxide in human articular chondrocytes . In addition, aceclofenac interferes with neutrophil adhesion to endothelium by decreasing the expression of L-selectin (CD62L), which is a cell adhesion molecule expressed on lymphocytes . Aceclofenac is proposed to stimulate the synthesis of glycosaminoglycan in human osteoarthritic cartilage which may be mediated through its inhibitory action on IL-1 production and activity . The chrondroprotective effects are generated by 4'-hydroxyaceclofenac which suppresses IL-1 mediated production of promatrix metalloproteinase-1 and metalloproteinase-3 and interferes with the release of proteoglycan from chrondrocytes .

Drotaverine is a selective inhibitor of phosphodiesterase 4 (PDE4), which is an enzyme responsible for the degradation of cyclic adenosine monophosphate (cAMP). Inhibition of PDE4 leads to elevated levels of cAMP, leading to smooth muscle relaxation. Recent research showed that low levels of cAMP have been associated with brain tumorigenesis, leading to the investigation of PDE4 inhibitors as potential anticancer agents.

Dosage

Heflacure Spas dosage

Adults: The maximum recommended dose is 200 mg daily, taken as two separate 100 mg doses, one tablet in the morning and one in the evening.

Children: There is no clinical data on the use of aceclofenac in children.

Elderly: The pharmacokinetics of aceclofenac are not altered in elderly patients, therefore it is not considered necessary to modify the dose and dose frequency.

Renal insufficiency: There is no evidence that the dosage of aceclofenac needs to be modified in patients with mild renal impairment.

Hepatic insufficiency: The dose of aceclofenac should be reduced in patients with hepatic impairment. An initial daily dose of 100 mg should be administered.

Aceclofenac SR tablet:

The recommended dose is 200 mg once daily.

Oral-

• Adults: 1 to 2 tablets, 3 times daily
• Children (over 6 years): 1/2 to 1 tablet, 1-2 times daily.
• Children (1-6 years): 1/4 to 1/2 tablet, 1-2 times daily.

Injection-

• Adults: 1 to 2 ampoules, intramuscularly or subcutaneously, 1-3 times daily.
• For the management of acute stone colics: 1 or 2 ampoules by slow intravenous injection.

Side Effects

Generally aceclofenac is well tolerated. The majority of side effects observed have been reversible and of a minor nature and include gastrointestinal disorders (dyspepsia, abdominal pain, nausea and diarrhoea) and occasional occurance of dizziness. Dermatological side effects including pruritus and rash. Abnormal hepatic enzyme levels and raised serum creatinine have occasionally been reported.

The common side effects are headache, dizziness, rhinitis, sinusitis, gastrointestinal upset, nausea, pharyngitis, edema and fatigue.

Toxicity

Some common adverse effects include gastro-intestinal disorders (dyspepsia, abdominal pain, nausea), rash, ruber, urticaria, symptoms of enuresis, headache, dizziness, and drowsiness . Oral LD50 value in rats is 130 mg/kg .

Oral LD₅₀ is 540 mg/kg in rats and 350 mg/kg in mice. There is limited information on drotaverine overdose and toxicity.

Precaution

Aceclofenac should be administered with caution to patients with symptoms indicative of gastrointestinal disorders, with a history of peptic ulceration, ulcerative colitis, Crohn\'s disease, hepatic porphyria, and coagulation disorders. Patients suffering from severe hepatic impairment must be monitored.

Caution should be taken for patients suffering from liver and kidney disease.

Interaction

Lithium and Digoxin: Aceclofenac, like many NSAIDs may increase plasma concentrations of lithium and Digoxin.

Diuretics: Aceclofenac, like other NSAIDs, may interact the activity of diuretics.

Anticoagulants: Like other NSAIDs, Aceclofenac may enhance the activity of anticoagulant. Close monitoring of patients on combined anticoagulants and Aceclofenac therapy should be undertaken.

Methotrexate: Caution should be exercised if NSAIDs and Methotrexate are administered within 24 hours of each other, since NSAIDs may increase Methotrexate plasma levels, resulting in increased toxicity.

May attenuate the action of levodopa. Concurrent use of analgesics, antimuscarinics or benzodiazepines. Additive beneficial effect with concurrent use of analgesics, antimuscarinics or benzodiazepines.

Volume of Distribution

The volume of distribution is approximately 25 L .

Following oral administration of a single 80 mg dose, the mean volume of distribution was 193 ± 48 L. Following an intravenous dose of 80 mg, the mean volume of distribution was 195 ± 48 L.

Elimination Route

Aceclofenac is rapidly and completely absorbed from the gastrointestinal tract and circulates mainly as unchanged drug following oral administration. Peak plasma concentrations are reached around 1.25 to 3 hours post-ingestion, and the drug penetrates into the synovial fluid where the concentration may reach up to 60% of that in the plasma . There is no accumulation in regular dosing, with similar maximum plasma concentration (Cmax) and time to reach peak plasma concentration (Tmax) after single and multiple doses .

Drotaverine is not completely absorbed following oral administration and its bioavailability is highly variable. Following oral administration of a single 80 mg dose, the absolute bioavailability ranged between 24.5 and 91 % with a mean of 58.2 ± 18.2%. Mean C_max was 292 ± 88 ng/mL. Mean AUC was 3251 ± 950 ng*h/mL. Mean T_max was 1.9 ± 0.54 hours.

Half Life

The mean plasma elimination half-life is approximately 4 hours .

Following oral administration of a single 80 mg dose, the mean half-life was 9.11 ± 1.29 hours. Following an intravenous dose of 80 mg, the mean half-life 9.33 ± 1.02 hours.

Clearance

The mean clearance rate is approximately 5 L/h .

Following oral administration of a single 80 mg dose, the mean renal clearance was 0.59 ± 0.18 mL/min. Following an intravenous dose of 80 mg, the mean renal clearance was 0.73 ± 0.29 mL/min.

Elimination Route

The main route of elimination is via the urine where the elimination accounts for 70-80% of clearance of the drug . Approximately two thirds of the administered dose is excreted via the urine, mainly as glucuronidated and hydroxylated forms of aceclofenac . About 20% of the dose is excreted into feces .

Drotaverine is mainly eliminated via hepatic metabolism. About 67% of the drug is found in feces and 20% of the drug was eliminated with urine.

Pregnancy & Breastfeeding use

Pregnancy: There is no information on the use of aceclofenac during pregnancy. Aceclofenac should not be administered during pregnancy, unless there are compelling reasons for doing so. The lowest effective dose should be administered.

Lactation: There is no information on the secretion of aceclofenac in breast milk. The use of aceclofenac should therefore be avoided during lactation unless the potential benefits to the mother outweigh the possible risks to the children.

As with most drugs, the use of Drotaverine Hydrochloride should be avoided during pregnancy and lactation unless essential.

Contraindication

Aceclofenac should not be administered to patients with active or suspected peptic ulcer or gastro-intestinal bleeding. It should not be given to patients with moderate to severe renal impairment. Close medical surveillance is also imperative in patients suffering from severe impairment of hepatic function. It should not be prescribed during pregnancy, unless there are compelling reasons for doing so. The lowest effective dosage should be used. Aceclofenac should not be administered to patients previously sensitive to Aceclofenac or in whom aspirin or NSAIDs precipitate attacks of asthma, acute rhinitis or urticaria or who are hypersensitive to these drugs.

Drotaverine is contraindicated in patients with known hypersensitivity to the products and its constituents.

Acute Overdose

There is no human data available on the consequences of aceclofenac overdosage. After overdosage, following therapeutic measures to be taken: absorption should be prevented as soon as possible by means of gastric lavage and treatment with activated charcoal. Supportive and symptomatic treatment should be given for complications.

Storage Condition

Keep at a cool and dry place, protected from light and moisture.
