MOXIDECTIN

The pharmacokinetic parameters of moxidectin following a single 8 mg oral dose of Moxidectin Tablets to healthy subjects and patients with onchocerciasis under fasted conditions are shown in Table 5. Mean moxidectin C max and AUC increased approximately proportionally to dose over a dose range of 2 to 36 mg (0.25 to 4.5 times the approved recommended dose) in healthy subjects under fasted conditions.

6.1 Clinical Trials Experience Because clinical trials are conducted under varying controlled conditions, adverse reaction rates observed in one clinical trial cannot be directly compared to rates observed in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Clinical Trials Experience in Adults and Pediatric Patients (12 Years to Less than 18 Years of Age) The safety of Moxidectin Tablets was evaluated in two randomized, double-blind, active-controlled studies in patients with confirmed onchocerciasis (Trial 1 and Trial 2) [see Clinical Studies ( ...

The following clinically significant adverse reactions are described in greater detail in other labeling sections: Cutaneous, Ophthalmological and/or Systemic Adverse Reactions [see Warnings and Precautio ns ( 5.1 )] Symptomatic Orthostatic Hypotension [see Warnings and Precautions ( 5.2 )] Encephalopathy in Loa loa Co-infected Patients [see Warnings and Precautions ( 5.3 )] Edema and Worsening of Onchodermatitis [see Warnings and Precautions ( 5.4 )] The most common adverse reactions (incidence...

Cutaneous, Ophthalmological and/or Systemic Adverse Reactions of Varying Severity (Mazzotti Reaction ) : This may occur in patients with onchocerciasis following treatment with Moxidectin Tablets. Monitor patients for symptoms, including symptomatic orthostatic hypotension. ( 5.1 ) Symptomatic Orthostatic Hypotension : Episodes of symptomatic orthostatic hypotension including inability to stand without support may occur in patients following treatment with Moxidectin Tablets.

7 DRUG INTERACTIONS 7.1 Midazolam (CYP3A4 substrate) In healthy subjects, concomitant administration of a single 8 mg oral dose of Moxidectin Tablets did not have an effect on the pharmacokinetics of midazolam [see Clinical Pharmacology ( 12.3 ) ]. Moxidectin can be co-administered with CYP3A4 substrates.
