Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. In the opinion of management, the accompanying unaudited interim condensed consolidated financial statements include all adjustments, consisting of normal recurring adjustments, which are necessary to present fairly the Company’s financial position, results of operations, comprehensive income, and cash flows. The consolidated balance sheet at December 31, 2024 has been derived from audited financial statements as of that date. The unaudited interim condensed consolidated statements of operations are not necessarily indicative of the results that may occur for the full fiscal year. Certain information and footnote disclosure normally included in financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to instructions, rules, and regulations prescribed by the U.S. Securities and Exchange Commission (the “SEC”). Therefore, these unaudited interim condensed consolidated financial statements should be read in conjunction with the Company’s audited financial statements and notes thereto previously distributed in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Form 10-K”), as filed with the SEC.
Principles of Consolidation	Principles of Consolidation The unaudited interim condensed consolidated financial statements include the accounts of ANI Pharmaceuticals, Inc. and its subsidiaries. All intercompany accounts and transactions are eliminated in consolidation.
Foreign Currency	Foreign Currency The Company currently has subsidiaries located in India, Ireland, Germany, and the United Kingdom. The India-based subsidiary generally conducts its transactions in Indian Rupees, which is also its functional currency. The Ireland and Germany locations generally conduct their transactions in Euros, which is also their functional currency. The United Kingdom subsidiary conducts its transactions in Euros and British Pounds, and their functional currency is Euros. The Company has ceased operations at its subsidiary in Oakville, Ontario, Canada as of March 31, 2023. The Canada-based subsidiary conducted its transactions in U.S. dollars and Canadian dollars, but its functional currency was the U.S. dollar. The results of any non-U.S. dollar transactions and balances are remeasured in U.S. dollars at the applicable exchange rates during the period and resulting foreign currency transaction gains and losses are included in the determination of net (loss) income. The gain or loss on transactions denominated in foreign currencies and the translation impact of local currencies to U.S. dollars was immaterial for the three months ended March 31, 2025 and 2024. Unless otherwise noted, all references to “$” or “dollar” refer to the U.S. dollar. The Company’s asset and liability accounts are translated using the current exchange rate as of the balance sheet date, except for shareholders’ equity accounts, which are translated using historical rates. Net revenues and expense accounts are translated using an average exchange rate over the period ended on the balance sheet date. Adjustments resulting from the translation of the financial statements of the Company’s foreign subsidiaries into U.S. dollars are accumulated as a separate component of shareholders’ equity within accumulated other comprehensive income, net of tax. Foreign currency transaction gains and losses include fluctuations related to long-term intercompany loans. Translation gains and losses on intercompany balances of a long-term investment nature are included in foreign currency translation adjustments in accumulated other comprehensive income.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. In the condensed consolidated financial statements (unaudited), estimates are used for, but not limited to, variable consideration determined based on accruals for chargebacks, administrative fees and rebates, government rebates, returns and other allowances, income tax provision or benefit, deferred taxes and valuation allowance, stock-based compensation, revenue recognition, allowance for inventory obsolescence, valuation of financial instruments and intangible assets, accruals for contingent liabilities, including contingent consideration and contingent value rights in acquisitions, fair value of long-lived assets, determination of right-of-use assets and lease liabilities, allowance for credit losses, and the depreciable lives of long-lived assets. Because of the uncertainties inherent in such estimates, actual results may differ from those estimates. Management periodically evaluates estimates used in the preparation of the financial statements for reasonableness.
Business Combinations And Goodwill	Business Combination and Goodwill The Company accounted for its acquisition of Alimera using the acquisition method of accounting prescribed by ASC 805, Business Combinations, whereby the results of operations, including the revenues and earnings of Alimera, are included in the financial statements from the date of acquisition. Assets acquired and liabilities assumed as of the date of acquisition are recognized at their fair values based on widely accepted valuation techniques in accordance with ASC 820, Fair Value Measurements. Goodwill is recognized for the excess of the consideration transferred over the net fair values of assets acquired and liabilities assumed. Management’s assessment of qualitative factors affecting goodwill for each acquisition includes estimates of market share at the date of purchase, ability to grow in the market, synergy with existing Company operations and the payor profile in the markets. The fair value assigned to the intangible assets was determined using the income approach, specifically the multi-period excess earnings methodology. The process for estimating fair values requires the use of significant estimates, assumptions and judgments, including determining the timing and estimates of future cash flows and developing appropriate discount rates. The estimates of fair value are based upon assumptions believed to be reasonable using the best information available. These assumptions are inherently uncertain and unpredictable and, as a result, actual results may differ materially from estimates. ASC 805, Business Combinations, establishes a measurement period to provide the Company with a reasonable amount of time to obtain the information necessary to identify and measure various items in a business combination and cannot extend beyond one year from the acquisition date. Measurement period adjustments are recognized in the reporting period in which the adjustments are determined and calculated as if the accounting had been completed as of acquisition date. The Company expects to complete the final fair value determination of the assets acquired and liabilities assumed as soon as practicable within the measurement period, but not to exceed one year from the acquisition date
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Issued Accounting Pronouncements Not Yet Adopted From time to time, new accounting pronouncements are issued by the FASB or other standard setting bodies and are adopted by the Company as of the specified effective date. Unless otherwise discussed, the Company believes that the impact of recently issued standards that are not yet effective will not have a material impact on its financial position or results of operations upon adoption. In December 2023, the FASB issued Accounting Standards Update ("ASU") 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which includes guidance to expand the disclosure requirements for income taxes, specifically related to the rate reconciliation and income taxes paid. These amendments are effective for all public entities for fiscal periods beginning after December 15, 2024, with early adoption permitted. These amendments apply on a prospective basis, but entities have an option to apply it retrospectively for all periods presented.
