1 Adverse Reaction Overview Summary of the safety profile The safety and tolerability of TWYNSTA has been evaluated in five controlled clinical studies with over 3500 patients, over 2500 of whom received telmisartan in combination with amlodipine.
No additional adverse reactions were identified in clinical trials with the combination telmisartan plus amlodipine compared to the adverse reactions of the monocomponents. Peripheral edema, a recognized dose dependent adverse reaction of the monocomponent amlodipine, was generally observed at a lower incidence in patients who received the telmisartan/amlodipine combination than in those who received amlodipine alone.
Adverse reactions previously reported with one of the monocomponents (telmisartan or amlodipine) may be potential adverse reactions with TWYNSTA as well, even if not observed in clinical trials or during the post-marketing period. Therefore, in addition to the reported adverse reactions during the TWYNSTA development program all adverse reactions reported in patients who received telmisartan or amlodipine monotherapy, have been listed for TWYNSTA.
Combination therapy showed a favourable safety profile, with lower edema rates than amlodipine monotherapies, especially when comparing amlodipine full-dose monotherapy with amlodipine low-dose combinations, which showed at least comparable or better efficacy.
2 Clinical Trial Adverse Reactions Clinical trials are conducted under very specific conditions.

1 Dosing Considerations Patients should be titrated on individual drugs. If the fixed dose combination represents the dose and dosing frequency determined by this titration, the use of TWYNSTA may be more convenient in the management of patients.

There were no serious cases. Almost all of the events were of mild or moderate intensity, and the majority of patients continued treatment and recovered without requiring therapy. In a single, randomized double-blind placebo controlled, 8-week factorial design comparing free dose combination telmisartan/amlodipine to monotherapy (telmisartan or amlodipine) and placebo, adverse events (AEs) occurred with similar frequency across the treatment groups, with the highest frequency in the telmisartan 80mg/amlodipine 5 mg (T80/A5) group but the incidence of all AEs, in all groups was within 4% of the placebo group.
Three serious adverse events occurred in the T80/A5 group, none of which were felt to be drug related. The three serious adverse events occurred in 3 different patients and included multiple fractures, deep venous thrombosis, and chest pain (see Table 2).

Additional data on long term safety was based on an open-label, limited study, of 6 month up to 8 months duration and no new safety signals were noted.

, to enhance convenience. Special populations Renal impairment No dosage adjustment is required for patients with renal impairment, including those on haemodialysis. Product Monograph TWYNSTA (telmisartan/amlodipine) Page 6 of 59 Hepatic impairment In patients with mild to moderate hepatic impairment TWYNSTA should be administered with caution.
For telmisartan the dosage should not exceed 40 mg once daily as hepatic impairment increases bioavailability (see Special Populations and Conditions - Hepatic insufficiency). Amlodipine dosage requirement have not been established in patients with impaired hepatic function.
When amlodipine is used in these patients, it should be initiated at the lower end of the dosing range and the dosage should be carefully and gradually adjusted depending on the patient’s tolerance and response. Geriatrics (> 65 years of age) No dose adjustment is necessary for elderly patients.
It should be recognized, however, that greater sensitivity in some older individuals cannot be ruled out. If required, increase in the dose should be done gradually and with caution (see 7 WARNINGS AND PRECAUTIONS and 10 CLINICAL PHARMACOLOGY).
Pediatric population (<18 years of age) TWYNSTA is not recommended for use in patients aged below 18 years due to a lack of data on safety and efficacy. Drug discontinuation If laryngeal stridor or angioedema of the face, extremities, lips, tongue, or glottis occurs, TWYNSTA should be discontinued immediately, the patient treated appropriately in accordance with accepted medical care, and carefully observed until the swelling disappears.
When pregnancy is detected, TWYNSTA should be discontinued as soon as possible. 4 Administration Tablet for oral administration TWYNSTA should be taken consistently with or without food. TWYNSTA tablets are for once- daily oral administration and should be swallowed whole with liquid.
5 Missed Dose If a dose is missed during the day, the next dose should be continued at the usual time. Do not double dose. 5 OVERDOSAGE Symptoms TWYNSTA: Signs and symptoms of overdose are expected to be in line with exaggerated pharmacological effects.
Telmisartan:
Limited data are available with regard to telmisartan overdosage in humans. The most prominent manifestations of overdosage were hypotension and/or tachycardia; bradycardia also occurred. It is not known if telmisartan can be removed from the body by hemodialysis.
Amlodipine:
Overdose with amlodipine may result in excessive peripheral vasodilatation and possibly reflex tachycardia. Marked and probably prolonged systemic hypotension up to and including shock with fatal outcome may occur. A patient who took 70 mg of amlodipine with benzodiazepine developed shock which was refractory to treatment and died.
In a 19 month old child who ingested 30 mg of amlodipine (about 2 mg/kg) there was no evidence of hypotension but tachycardia (180 bpm) was observed. 5 hrs after ingestion and on subsequent observation (overnight) no sequelae were noted.
Therapy Gastric lavage may be worthwhile in some cases. In healthy volunteers the use of charcoal up to 2 hours after administration of amlodipine 10 mg has been shown to […]
