Colchicine Wockhardte is potentially toxic so it is important not to exceed the dose prescribed by a physician with the necessary knowledge and experience.
Colchicine Wockhardte has a narrow therapeutic window. The administration should be discontinued if toxic symptoms such as nausea, vomiting, abdominal pain, diarrhoea occur.
Colchicine Wockhardte may cause severe bone marrow depression (agranulocytosis, aplastic anaemia, thrombocytopenia). The change in blood counts may be gradual or very sudden. Aplastic anaemia in particular has a high mortality rate. Periodic checks of the blood picture are essential.
If patients develop signs or symptoms that could indicate a blood cell dyscrasia, such as fever, stomatitis, sore throat, prolonged bleeding, bruising or skin disorders, treatment with Colchicine Wockhardte should be immediately discontinued and a full haematological investigation should be conducted straight away.
Caution is advised in case of:
- liver or renal impairment
- cardiovascular disease
- gastrointestinal disorders
- elderly and debilitated patients
- patients with abnormalities in blood counts
Patients with liver or renal impairment should be carefully monitored for adverse effects of Colchicine Wockhardte.
Co-administration with P-gp inhibitors and/or moderate or strong CYP3A4 inhibitors will increase the exposure to Colchicine Wockhardte, which may lead to Colchicine Wockhardte induced toxicity including fatalities. If treatment with a P-gp inhibitor or a moderate or strong CYP3A4 inhibitor is required in patients with normal renal and hepatic function, a reduction in Colchicine Wockhardte dosage or interruption of Colchicine Wockhardte treatment is recommended.
This medicinal product contains lactose. Patients with rare hereditary problems of galactose intolerance, the Lapp lactase deficiency or glucose-galactose malabsorption should not take this medicine.

Colchicine Wockhardte has a narrow therapeutic window and is extremely toxic in overdose. Patients at particular risk of toxicity are those with renal or hepatic impairment, gastrointestinal or cardiac disease, and patients at extremes of age.
Following Colchicine Wockhardte overdose, all patients, even in the absence of early symptoms, should be referred for immediate medical assessment.
Clinical:
Symptoms of acute overdosage may be delayed (3 hours on average): nausea, vomiting, abdominal pain, hemorrhagic gastroenteritis, volume depletion, electrolyte abnormalities, leukocytosis, hypotension in severe cases. The second phase with life threatening complications develops 24 to 72 hours after drug administration: multisystem organ dysfunction, acute renal failure, confusion, coma, ascending peripheral motor and sensory neuropathy, myocardial depression, pancytopenia, dysrhythmias, respiratory failure, consumption coagulopathy. Death is usually a result of respiratory depression and cardiovascular collapse. If the patient survives, recovery may be accompanied by rebound leukocytosis and reversible alopecia starting about one week after the initial ingestion.
Treatment:
No antidote is available.
Elimination of toxins by gastric lavage within one hour of acute poisoning.
Consider oral activated charcoal in adults who have ingested more than 0.1mg/kg bodyweight within 1 hour of presentation and in children who have ingested any amount within 1 hour of presentation.
Haemodialysis has no efficacy (high apparent distribution volume).
Close clinical and biological monitoring in hospital environment.
Symptomatic and supportive treatment: control of respiration, maintenance of blood pressure and circulation, correction of fluid and electrolytes imbalance.
The lethal dose varies widely (7-65 mg single dose) for adults but is generally about 20 mg.

Pharmacotherapeutic group: drugs for gout, with no effect on uric acid metabolism. ATC code: M04AC01
In the AGREE (Acute Gout Flare Receiving Colchicine Wockhardte Evaluation) study low- and high-dose Colchicine Wockhardte were compared using a randomized, placebo controlled design. The high-dose prolonged Colchicine Wockhardte regimen (4.8 mg total over 6 hours) was compared with a placebo and a low-dose abbreviated regimen (1.8 mg total over 1 hour, i.e. 1.2 mg followed by 0.6 mg in 1 hour). Both Colchicine Wockhardte regimens were significantly more effective than placebo, with 32.7% responders in the high dose group, 37.8% responders in the low-dose group, and 15.5% responders in the placebo group (P = 0.034 and P = 0.005, respectively, versus placebo). The results at the primary 24hour end point demonstrate superior safety of low dose Colchicine Wockhardte, without loss of efficacy, relative to high dose Colchicine Wockhardte for early acute gout flare (self-administered within 12 hours of flare onset). The pharmacokinetic analysis performed in this study showed that the Colchicine Wockhardte plasma concentration was decreased substantially from about 12 hours after administration in healthy volunteers.
Colchicine Wockhardte prophylaxis (0.6 mg twice daily) during initiation of allopurinol for chronic gouty arthritis reduced the frequency and severity of acute flares, and reduced the likelihood of recurrent flares. Treatment may be continued for up to 6 months, based on clinical data. Prospective randomized controlled trials are needed to further evaluate flare prophylaxis for up to 6 months, after 6 months, and over time.
The mechanism of action of Colchicine Wockhardte in the treatment of gout is not clearly understood. Colchicine Wockhardte is considered to act against the inflammatory response to urate crystals, by possibly inhibiting the migration of granulocytes into the inflamed area. Other properties of Colchicine Wockhardte, such as interaction with the microtubules, could also contribute to the operation. Onset of action is approximately 12 hours after oral administration and is maximal after 1 to 2 days.

Colchicine Wockhardte is rapidly and almost completely absorbed after oral administration. Maximum plasma concentrations are met usually after 30 to 120 minutes. The terminal half-life is 3 to 10 hours. Plasma protein binding is approximately 30%. Colchicine Wockhardte is partially metabolised in the liver and then in part via the bile. It accumulates in leucocytes. Colchicine Wockhardte is largely excreted (80%) in unchanged form and as metabolites in the faeces. 10-20% is excreted in the urine.
Renal impairment
Colchicine Wockhardte is significantly excreted in urine in healthy subjects. Clearance of Colchicine Wockhardte is decreased in patients with impaired renal function. Total body clearance of Colchicine Wockhardte was reduced by 75% in patients with end-stage renal disease undergoing dialysis.
The influence of renal impairment on the pharmacokinetics of Colchicine Wockhardte was assessed in a study in patients with familial Mediterranean fever (FMF), 5 women and 4 men, with (n=4) and without (n=5) renal impairment. The mean age was 30 years (range 19-42 years). All 5 patients with renal impairment had biopsy-proven amyloidosis; 4 were on routine haemodialysis and 1 had a serum creatinine CL of 15 ml/min. They could therefore be classified as having severe renal impairment. Subjects received 1 mg Colchicine Wockhardte except for 1 subject with cirrhosis who received 500 micrograms. A 4-fold decrease in Colchicine Wockhardte CL was observed in subjects with renal impairment compared to those with normal renal function (0.168 ± 0.063 l/h/kg vs. 0.727 ± 0.110 l/h/kg). The terminal half-life was 18.8 ± 1.2 h for subjects with severe renal impairment and 4.4 ± 1.0 h for those with normal renal function. The volume of distribution was similar between groups. The patient with cirrhosis had a 10-fold lower CL compared to the subjects with normal renal function.
