Rapiflo

Rapiflo capsule is indicated for the treatment of the signs and symptoms of benign prostatic hyperplasia (BPH).

Highly effective for the treatment of Benign Prostatic Hyperplasia.

Highest uroselectivity to alpha-1 adrenergic receptor.

Effective treatment option for BPH who are not responding to Tamsulosin.

Dose not cause orthostatic hypotension.

Convenient once-daily dosing.

Rapiflo is not indicated for the treatment of hypertension.

Silodosin is a selective antagonist of post-synaptic alpha-1 adrenoreceptors, which are located in the human prostate, bladder base, bladder neck, prostatic capsule and prostatic urethra. Blockade of these alpha-1 adrenoreceptors can cause smooth muscle in these tissues to relax, resulting in an improvement in urine flow and a reduction in BPH symptoms.

The recommended dose is Silodosin 8 mg orally once daily with a meal. 4 mg capsules taken orally once daily with a meal for those with moderate renal impairment (CrCl 30-50 mL/min).

Strong P-glycoprotein inhibitors (e.g., cyclosporine): Co-administration may increase plasma Rapiflo concentration. Concomitant use of PDE5 inhibitors with alpha-blockers including Rapiflo can potentially cause symptomatic hypotension.

Patients with severe renal & hepatic impairment, concomitant administration with strong Cytochrome P450 3A4 (CYP3A4) inhibitors (e.g., ketoconazole, clarithromycin, itraconazole, ritonavir) and patients with a history of hypersensitivity to Silodosin.

Most common adverse reactions are retrograde ejaculation, dizziness, diarrhea, orthostatic hypotension, headache, nasopharyngitis and nasal congestion.

Pregnancy Category B. Silodosin is not indicated for use in women. An embryo/fetal study in rabbits showed decreased maternal body weight at 200 mg/kg/day (approximately 13-25 times the maximum recommended human exposure or MRHE of Silodosin via AUC). No statistically significant teratogenicity was observed at this dose. Silodosin was not teratogenic when administered to pregnant rats during organogenesis at 1000 mg/kg/day (estimated to be approximately 20 times the MRHE). No maternal or fetal effects were observed at this dose. Rats and rabbits do not produce glucuronidated Silodosin, which is present in human serum at approximately 4 times the level of circulating Silodosin and which has similar pharmacological activity to Silodosin. No effects on physical or behavioral development of offspring were observed when rats were treated during pregnancy and lactation at up to 300 mg/kg/day.

Postural hypotension with or without symptoms (e.g. dizziness) may develop when beginning Rapiflo treatment. Rapiflo should not be used in combination with other alpha-blocker. Inform patients planning cataract surgery to notify their ophthalmologist that they are taking Rapiflo because of the possibility of Intraoperative Floppy Iris Syndrome (IFIS)

Rapiflo was evaluated at doses of up to 48 mg/day in healthy male subjects. The dose-limiting adverse event was postural hypotension. Should overdose of Rapiflo lead to hypotension, support of the cardiovascular system is of first importance. Restoration of blood pressure and normalization of heart rate may be accomplished by maintaining the patient in the supine position. If this measure is inadequate, administration of intravenous fluid should be considered. If necessary, vasopressors could be used, and renal function should be monitored and supported as needed. Dialysis is unlikely to be of significant benefit since Rapiflo is highly (97%) protein bound.

Store at below 30°C in a dry place protected from light. Keep out of reach of Children.
